INSTALLION INSTRUCTIONS DUCTED SYSTEM IS700-IS900

Timber Frame Construction for Ducted IS700-IS900

STEP 1: Build Timber Frame Construction

Build the timber frame construction as illustrated. Ensure required clearances and access panels are noted for removal of the off-take and flue system for servicing the heater. The heater must be installed a minimum of 300mm from the floor.

Illustration: A diagram showing a timber frame structure designed to house the gas heater. It depicts the basic box-like construction with internal supports and openings for the heater unit and ducting connections.

STEP 2: Position Heater into Timber Frame

Position the heater into the constructed timber frame.

IS700 CoAxial Flue Installation: Pages 14, 15, 16

IS900 Single Flue Installation: Pages 16, 18, 19, 20, 21, 22

IS900 CoAxial Flue Installation: Pages 17, 23, 24

STEP 5: Connect Power to Heater

NOTE: If the heater is directly wired to the main electricity supply, an external power isolation switch must be installed to enable the heater to be isolated from incoming mains power.

Ducting Installation

STEP 6: Fit Offtake Duct to Heater

Secure the offtake duct to the top panel with wing nuts.

Illustration: Two images showing the gas heater unit with the offtake duct attached to the top. The first image shows the heater with logs and flames, connected to the duct. The second image shows the heater unit from the side, with the duct connection visible.

STEP 7: Connect 6 Meters of 250mm Duct to Offtake

Connect 6 meters of 250mm duct to the offtake.

Illustration: A diagram depicting the timber frame construction with the heater inside. A 250mm duct is shown connecting from the heater's offtake, extending outwards, and leading to an inline fan.

STEP 8: Fit Inline Fan with Support Brackets to 250mm Duct

NOTE: The minimum distance of the inline fan must be 6 meters from the offtake. Secure the inline fan brackets with screws to the timber base. Ensure the fan is installed with the provided support brackets and screwed to a solid timber base to absorb motor vibration. Failure to do so may void the warranty from the motor supplier.

Image: A photograph of an inline duct fan. The fan has a cylindrical metal casing with mounting brackets attached. Labels indicate model information such as "EBM R2E225-RA 9239", "230v~50 HZ 0,68A 1551", "2500/RPM", and "Ins C1.B".

Electrical and Commissioning

Step 9: Connect Temperature Switch and Fan Speed Controller

Connect the 40-degree temperature switch cable from the inline fan to the offtake. Install the fan speed controller with the supplied leads and plugs.

Electrical Diagram: A schematic showing the ducting system's electrical connections. It illustrates the ducting take-off with a 40°C temperature switch, the ducting fan, and a fan speed controller with an On/Off switch. Components are numbered 1 through 5, corresponding to: 1-Ducting take-off with 40°C temp. switch; 2-Ducting fan with leads and plug; 3-240 Volts extension lead (not supplied); 4-Fan speed controller with leads and plugs; 5-240 Volts extension lead (not supplied).

Step 10: Commissioning Heater and Ducting System

Prior to finishing the timber frame construction with sheet plaster or alternative materials, test run the heater and ducting system.

1. Remove the main door from the heater.
2. Remove packaging material from inside the firebox.
3. Check log placement to ensure all logs are in the correct position.
4. Test run the heater manually or with remote control operation to ensure the heater and ducting system are operating correctly.
5. Follow instructions in the operating manual for heater operation.

NOTE: For the ducting system to be activated, the heater needs to be operating on both burners for 30 minutes for the inline fan to activate.

Note: The speed controller switch should be in the ON position. Turn the speed controller switch to select the heat output to the ducting system.

Access Panel Installation

Access Panel Installation IS700

After the heater and ducting system has been successfully commissioned, finish the timber frame construction with sheet plaster or alternative materials.

NOTE: Access panels on the Right-Hand (R/H) and Left-Hand (L/H) sides, made of plaster sheet or alternative materials, are required for the removal of the OFFTAKE and flue system. These panels are also necessary for servicing the combustion fan and heat exchanger, which are located at the back of the heater.

Follow supplied instructions and illustrations.

Diagrams: Two diagrams illustrating timber frame construction for access panels on the R/H and L/H sides for Model IS700. Dimensions are provided for the panel openings and surrounding frame structure, indicating clearances and placement for servicing.
