Rinnai Symmetry RDV3610 Installation Manual

Installation Manual

Diagram shows a framed structure with the Rinnai Symmetry unit installed, before cladding. A separate view shows the unit within a wall cavity with a vent.

Note: Not intended as a fireplace insert.

The appliance, including the flue, is installed after framing and before cladding. Rinnai strongly recommends the appliance is fully tested before any cladding materials are applied. Cladding must be installed up to the flange and not over it; any overhang will alter the performance of the appliance and cause an unsafe situation. The appliance must be installed with a Rinnai supplied flue system. Installation may require two people due to the size and weight of the appliance. The appliance must be installed, commissioned, and serviced by a licensed tradesperson in accordance with all applicable local rules and regulations.

• Unit Depth (internal frame): 750 mm

Cover panel: Covers a 150 mm opening on both sides of the heater. It is removed only when a Symmetry Heat Transfer Kit is installed.

Location

The main points governing location are flueing and warm air distribution. The heater must not be installed where curtains or other combustible materials could come into contact with the appliance. In some cases, curtains may need restraining. Refer to the next page for clearance details.

The heater must be positioned on a flat, level surface. For installations further up the wall, the heater needs to be supported, either by constructing a base using board or supporting with joists.

Enclosure Dimensions

Diagram shows a framed enclosure for the unit. Key dimensions indicated are:

• Minimum Height: 850 mm
• Minimum Width: 1100 - 1125 mm
• Minimum Depth: 540 mm

Note: If installing the Symmetry Heat Transfer Kit, allow an additional side clearance of 250 mm. This 250 mm clearance is required to ensure the ducting does not come into contact with the fire.

The 540 mm minimum dimension provides a 25 mm clearance (plus) from the back of the unit.

A 25 mm clearance is required around the unit (sides and back).

Enclosure Dimensions in a Corner

Diagram shows the minimum enclosure dimensions required when the unit is installed in a corner. Key dimensions are:

• Width: 1830 mm
• Height: 915 mm
• Depth: 1295 mm

Clearances

The appliance must not be installed where curtains or other combustible materials could come into contact with the heater. In some cases, curtains may need restraining. The clearances listed below are minimum clearances unless otherwise stated.

Diagram illustrating clearances. Arrows indicate distances:

• To ceiling: 1000 mm
• Side clearances (non-combustible cladding): 400 mm

Note: The 400 mm side clearance includes side walls.

Up-wall Installations

If the Symmetry is being installed up the wall, the recommended minimum clearance is 1000 mm to the ceiling.

Non-combustible Cladding

Non-combustible cladding, such as 9 mm Eterpan MD (extending at least the full width of the appliance and 400 mm in height), must be installed directly above the fire as shown. This is required to minimise the risk of scorching or fire in the event of a power failure (when the fan stops running and hot air will rise directly above the unit).

1 9mm Eterpan MD (medium density) is supplied by PBS Ltd (www.pbs.co.nz). Other materials may also be suitable; please seek advice from a cladding supplier as to the correct application and specification of the material.

Mantels, Surrounds, and Hearths

Diagram shows a fireplace opening with a mantel shelf and surround. Labels indicate:

• A - Mantel height from top of glass
• B - Mantel depth
• C - Surround from side of glass
• D - Surround projection

A mantel and surround are allowed, provided they are outside the minimum clearances shown below. Due to the number of different sized Symmetry frames, the dimensions are taken from the edge of the glass.

For every 50 mm of added mantel depth, there must be an additional 100 mm of vertical clearance. For example; a mantel depth (B) of 350 mm will require 450 mm (A) of vertical clearance.

Hearths

A hearth is not necessary but can be used for decorative purposes or protection of sensitive flooring if required. It must not obscure the front of the fire.

TV Installation Above a Fireplace

If installing a flat screen TV above the fire, the main issue is heat. Heat from the fire and heat from the flueing components that sit behind the TV, especially if recessed, can be problematic.

The Symmetry RDV3610 has a fan that distributes warm air from the top of the appliance out into the room. As warm air is dispersed outwards rather than directly upwards, installation of a TV may be an option. The following are recommended minimum clearances when installing a TV directly above the Symmetry RDV3610 or into a recess. All dimensions are in mm.

Diagrams show two scenarios: 'Directly Above' and 'Recessed'.

• Directly Above: Shows a TV mounted above a mantel. Clearances indicated: 75 mm (from TV to flue), 400 mm (from mantel to flue).
• Recessed: Shows a TV mounted in a recess above the fireplace. Clearances indicated: 20 mm (from TV to recess wall), 220 mm (from TV to fireplace unit), 400 mm (from mantel to flue).

The 400 mm dimension is the minimum clearance required to combustibles and to a mantel.

For a TV mounted directly above the Symmetry RDV3610, the mantel must be at least the depth of the TV to deflect the heat away from the appliance.

It is up to the owner to check the TV installation instructions with the TV supplier to verify clearances. Some TV manufacturers have warranty conditions that state a TV is not to be installed above a fireplace.

Rinnai does not accept any responsibility for damage to a TV resulting from the use of this information.

Building the Frame

Using the dimension drawing below and the information on pages 5-8, construct a frame.

[!] A 25 mm clearance is required around the unit (sides and back).

Diagram shows a framed structure with dimensions:

• Minimum Height: 850 mm
• Minimum Depth: 540 mm
• Minimum Width: 1100 - 1125 mm

Note: If installing the Symmetry Heat Transfer Kit, allow an additional side clearance of 250 mm. This 250 mm clearance is required to ensure the ducting does not come into contact with the fire.

The 540 mm minimum dimension provides a 25 mm clearance (plus) from the back of the unit.

Electrical Connection

The standard electrical connection is to the right side of the front of the appliance. If necessary, this can be changed by an electrician to terminate on the left. The appliance must not be located immediately below a socket outlet (potential fire hazard).

The connection is either direct wired or connected to a power point within the cavity. A 1500 mm power cord is supplied with a 3-pin plug. This must be connected to a dedicated earthed power point. The electric isolation switch must be accessible after the appliance has been installed.

The electrical cord is not fire-rated and should not come into contact with the fire. If the supply cord is damaged, it must be replaced by a licensed tradesperson. This must be a genuine replacement part available from Rinnai, part number 6765B.

Diagram shows a close-up of the appliance's rear or side, indicating a 250 mm clearance requirement for the electrical connection.

Bracket Installation

Install the four metal mounting brackets supplied onto the Symmetry RDV3610. The position of the brackets will depend on the cladding thickness and type of installation (framed or frameless).

The Symmetry RDV3610 can be installed with the Rinnai granite and metal frames, and also as a frameless installation. The frameless installation can accommodate brick, rock veneer, or tiles, which sit tight up against the framing plate of the fireplace.

The metal mounting bracket adjusts 20 mm to allow for different cladding thicknesses. Refer to the diagrams below.

Diagram 1: Shows a bracket in the 'forward position' for Rinnai granite or metal frame, with backing board around the framing plate.

Diagram 2: Shows a bracket in the 'middle position' for frameless brick or tile installation with a brick recess. The front face of the backing board is level with the back face of the framing plate.

Diagram 3: Shows a bracket in the 'back position' for frameless brick or tile installation with a shallower brick recess. The front face of the backing board sits behind the framing plate.

Fixing the Unit to the Frame

The Symmetry RDV3610 comes pre-assembled with the burner already in position. For all installations, the unit MUST BE positioned on a level surface.

1. Position the unit inside the cavity.
2. Bend and secure the two metal standoffs supplied with the unit into position. These provide the required 150 mm minimum vertical clearance to the upper lintel.
3. Fix the unit to the frame with the four mounting brackets. These act as seismic constraints as well as providing the horizontal clearance to the frame.
4. Install the glass front. This will help protect the unit while the remaining installation work is completed. The carton in which the Symmetry is packaged has a cardboard cut-out that is the same size as the glass frame. This can also be used to protect the unit during installation.

• Flue Elbow Strap (R3644): Used to prevent excessive weight in the flue elbow.
• Flue Restrictor (11516): Supplied component. Maintains efficiency by restricting air flow as flue length increases.

Flue Installation - General Guidelines

Every gas fireplace requires a flue system that will draw effectively and clear flue products safely under all potential wind and climatic conditions.

It is the installer's responsibility to ensure the appliance is provided with an effective flue. The following guidelines assist with flue design and should be viewed in conjunction with the flue manufacturer's installation instructions and the Horizontal Flue Flashing Kit instruction sheet.

The Rinnai Symmetry RDV3610 must be installed with an approved Rinnai flue system. Approved flue components are detailed in this manual.

Clearance to Combustibles

Diagram shows concentric flue pipes (inner 100 mm, outer 170 mm) and combustible material.

Minimum clearance from the inner flue to combustible material must be greater than 50 mm (equates to 15 mm from the outer flue).

Flashings

A wall thimble and flashing kit is supplied with the Horizontal Through The Wall Kit. For all other flueing configurations, flashings must be specified.

Flue Cowl Clearance

To ensure products of combustion are cleared, adequate clearance for the building is required. The guideline is recommended as follows:

The flue cowl should have a 500 mm clearance from any part of the building. This also applies to steepled and pitched roofs, which should be clear of the ridge line. Lesser clearances may provide adequate flue systems depending on the installation. Minimum clearances are shown in NZS 5261.

Flue Terminal Locations

Must be compliant with 'Clearances Required for Flue Terminals' from NZS 5261 2003. The flue is not to terminate under floors or in a roof space.

Self-supporting Flue

The weight of the flue system should not be supported by the appliance; it should be self-supporting. Supporting the flue is usually completed during the framing stage with flue supports or straps within the cavity. Wall straps have been included in the Rinnai Vertical Flue Kit to assist with this. Elbow straps are also available as a separate component to prevent excess weight on the flue elbow.

Shared Flues

Gas appliances must not be connected to a chimney or flue serving a separate fuel-burning appliance.

Flue Installation - Vertical Termination

For vertical flue terminations with or without 45° bends (maximum of two). The shaded sections determine the position of the flue restrictor.

Diagram shows a vertical flue system with height markers and shaded zones indicating restrictor positions:

• Max. 5.4 m
• 4.2 m: Restrictor position # 2
• 3.0 m: Restrictor position # 3
• 1.8 m: Restrictor position # 4
• Min. 0.6 m: No restrictor

If a bend is greater than 45°, the installation is deemed a vertical termination with 90° bends (refer to the next page).

Vertical Termination with 90° Bends

For vertical flue terminations with two 90° bends (maximum of two). The shaded sections determine the position of the flue restrictor.

Horizontal runs of flue pipe must be supported to prevent any downward sags. Horizontal pipe sections should be supported at least every 1.2 m. Wall straps can be used for this purpose.

The horizontal run of flue pipe must have a 20 mm rise for every 1 m of run towards the termination. Never allow the flue pipe to run downward, as a downward slope can trap heat and become a fire hazard.

Diagram shows a vertical flue system with two 90° bends and horizontal runs, indicating restrictor positions and clearance requirements:

• Max. 5.4 m
• 4.2 m: Restrictor position # 2
• 3.0 m: Restrictor position # 3
• 1.8 m: Restrictor position # 4
• Min. 0.6 m (after bend): No restrictor
• Max. 3.5 m (horizontal run)

Flue Installation - Horizontal Termination

For horizontal flue terminations with a 90° bend (maximum of one). The shaded sections determine the position of the flue restrictor.

Horizontal runs of flue pipe must be supported to prevent any downward sags. Horizontal pipe sections should be supported at least every 1.2 m. Wall straps can be used for this purpose.

The horizontal run of flue pipe must have a 20 mm rise for every 1 m of run towards the termination. Never allow the flue pipe to run downward, as a downward slope can trap heat and become a fire hazard.

Diagram shows a horizontal flue system with height markers and shaded zones indicating restrictor positions:

• Max. 5.4 m
• Max. 1.2 m (horizontal run)
• 4.2 m: Restrictor position # 3
• 2.4 m: Restrictor position # 4
• Min. 0.6 m (horizontal run): No restrictor
• Min. 0.3 m, Max. 0.9 m (horizontal run)
• Max. 3.5 m (horizontal run)

Example:

• Vertical flue: 5.0 m (calculated as (6.03 - 5.0) / 0.52)
• Max. horizontal flue: 2.0 m
• Max. horizontal calculation: Max. Horizontal = (6.03 - Vertical) / 0.52

Example 2:

• Vertical flue: 2.0 m
• Max. horizontal flue: 2.9 m
• Max. horizontal calculation: Max. Horizontal = Vertical / 0.692

Gas Connection

The gas connection from the control valve is a 1/2" BSP male flare fitting. This connects straight into the gas control on the lower left-hand side of the appliance.

Gas pipe sizing must consider the gas input to this appliance as well as all other gas appliances in the premises.

Diagram shows side and front views of the appliance, highlighting the gas connection point and dimensions. A close-up shows the 'Connection Access' area with 'Flared Union' and 'Gas Control' labels.

Note: To access the gas connection, remove the upper and lower bracket (also called the service access panels). The brackets can be removed by undoing the screws shown below at each end.

Flue Restrictor Installation

Different flue configurations require different positioning of the flue restrictor. Refer to the 'Flue installation' pages to determine what setting is required. The flue restrictor works by limiting the amount of air required for combustion. The higher the flue, the more air is circulated, which can affect the performance of the fire.

The different hole positions are shown below. These are stamped on the flue restrictor.

Diagram shows the flue restrictor with numbered holes (1, 2, 3, 4) and two possible installation positions.

Before you can install the flue restrictor, you need to remove the pilot shield and carefully lift the burner bed out of the unit. Attach the flue restrictor as shown by securing with the screws provided.

Diagram shows the burner assembly with the flue restrictor being fitted.

Log Set Installation

The log set (burn media) is packaged separately and consists of five log pieces and three moulded rocks. Handle the log set with care to avoid chipping.

It is important to position the pieces in order as shown below, as incorrect placement can create carbon build-up and affect performance. Malfunctioning due to improper log/rock placement is not covered under warranty. The unit must never be used with broken logs and should not be mixed with other burn media (except Rinnai Rockwool).

Diagram shows the 'Final Log Set Layout' with labels for each log and rock piece: Top log, Front middle left log, Front base left log (with moulded rock), Front base right log, Front left rock, Round flat rock, Triangular shaped rock.

The rocks form an important part of the log set and must be positioned as shown. There are three distinct shapes, identified below.

Diagrams show the three rock shapes: 'Front left rock', 'Round flat rock', and 'Triangular shaped rock'.

Step-by-step Log Set Installation

1. Carefully remove log set from packaging and fit Front Base Left Log in the created gap. It should only fit one way.
2. Fit Front Base Right Log into position on the far right of the burner base.
3. Fit Front Middle Left Log into the back flat section of the burner and slot on top of Front Base Left Log.
4. Place Front Middle Right Log into the U-shaped groove.
5. Place the Top Log onto the recessed sections of the Left and Right Middle Logs. Ensure the middle elbow section rests on the top of the Bottom Log.
6. Position the round flat rock and front left rock over the screw holes. Keep them as far away as possible from the glass, while making sure they still cover the holes. Place the remaining triangular shaped rock on top of the round flat rock as shown.

Test Pressures

1. Turn on the gas and power supply to the unit.
2. Refer to the data plate for applicable test point pressures.
3. The test point is on the gas control valve. Using a suitable screwdriver, loosen the captivated test point screw and attach a manometer.
4. Using the manual control switch (on the appliance), turn the unit on and switch to the HIGH setting and adjust the pressure as necessary.
5. Disconnect the solenoid (yellow wire). This will ensure the unit is on the lowest setting, and set the appliance to the LOW setting. Adjust the pressure as necessary. Reconnect the solenoid.

Diagram shows a gas control valve with labels for 'Inlet test point', 'Outlet test point', 'Cap', 'Gas outlet', 'High pressure adjusting screw', and 'Low pressure adjusting screw'. It also includes a note: 'Adjust test point pressures as necessary using a screwdriver and spanner as shown below'.

6. After checking pressures, turn the unit off, remove the manometer, and replace the test point screw.
7. Turn the heater on and off a few times to check ignition.
8. When you are satisfied that the heater is working correctly, reassemble and start the appliance to check the flame pattern (refer to the next page).

Flame Pattern

It may take approximately two hours of operation for the logs to achieve their full flame pattern and glow. During the initial burning-in period, some smoke and smell may be experienced. The appliance should be run on the high setting in a well-ventilated room until these dissipate. It is important to check the flame pattern during this time.

Abnormal Flame Pattern

Abnormal flame performance and/or pattern can indicate a problem with the fire, such as blocked gas injectors or artificial logs/burn media having shifted during installation. There are some warning signs that could indicate a problem:

• Unusual smell from the appliance
• Continued difficulty or delay in establishing a flame
• Flame appears either very short or very long
• Flame only burns part way across the burner
• Severe soot building up on the inside of the glass door

Diagrams compare 'Normal' flame pattern with 'Abnormal' flame pattern.

[!] It is the responsibility of the installer to check that under normal conditions of the appliance, all flue gases are exhausted to the outside atmosphere and that there are no spillage of combustion gases into the room.

If the appliance cannot be made to perform correctly, please contact Rinnai.

Cladding

Non-combustible cladding must be installed directly above the fire as shown on page 7. When installing cladding, ensure it is installed up to the flange and not over it. Any overhang will affect the performance of the appliance and cause an unsafe situation.

Diagram shows a close-up of cladding installation, indicating that 'Cladding should be installed hard up against the flange and not over it.'

Fitting the Frames and Dress Guard

[!] Before fitting the frames and/or dress guard, ensure the glass front is secured in place. It is critical when fitting the glass front that you double-check that it is not scratched or damaged in any way and that you have checked the gasket.

Diagram shows the components: Inner Frame, Outer Frame, and Dress Guard.

Inner Frame

Hook over the glass and secure in place on the two large lower magnets on the front assembly.

Outer Frame

Screw into position with the four screws provided. If you have a granite outer frame, refer to separate installation instructions.

Mesh Dress Guard

No fixings required; this inserts flush into the inner frame by hooking onto the top and then pushing in.

Commissioning

Complete the installation and commissioning checklist in the customer operation manual and make sure you leave the manual with the customer. Explain to the customer about the use and care of the unit and ensure they understand the instructions and operation of the appliance.

If operating without a dress guard, advise the customer of the safety instructions to prevent the risk of injury.
