Input is 36,000 BTU/HR.

A 1/8" N.P.T. plugged tapping is provided on the gas control along side of the outlet to the main burner for a test gage connection.

These appliances must not be connected to a chimney flue servicing a solid fuel burning appliance.

These appliances must be isolated from the gas supply piping system by dosing their individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig.

The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test temperatures in excess of 1/2 PSIG (KPa).

Assembly Steps

1. Position appliance prior to framing or into prepared framing.
2. Route gas line up to firebox compartment and install millivolt wall switch.
3. Install chimney or vent system.
4. Complete finished wall material and trim. (Refer to page 12 for Removal of Corner Shipping Posts.)
5. Install controls and burner assembly. Connect to gas supply.
6. Wire remote millivolt wall switch to control valve and door switches.
7. Uncarton and install glass doors.

Installation

Step 1. Frame fireplace enclosures as illustrated in Figures 1, 2, 3 or 4.

Figure 1 (GST Framing): Shows a rectangular opening with dimensions indicating framing for the GST model. Key dimensions include 41" height, 20 1/2" width, and 3" minimum clearance.

Figure 2 (GPF Framing): Shows a rectangular opening with dimensions indicating framing for the GPF model. Key dimensions include 41" height, 20 1/2" width, and 3" minimum clearance.

Figure 3 (Inside Corner Installation GCR (Right Open) Framing): Shows framing for an inside corner installation of the GCR model. Key dimensions include 41" height, 33 1/8" width, and 25 3/16" depth, with a 3" minimum clearance.

Step 2. Route a 1/2" NPT black iron gas line 4 13/16" above the floor surface (if fireplace will be resting on the floor) and 4" behind the face of the rough framing (Figure 5).

Figure 5: Illustrates the gas line routing relative to the framing, showing a 1/2" NPT gas line extending 4 13/16" above the floor and 4" behind the framing.

Note: Gas piping should be routed to the front side of framing in line with the gas controls (Refer to appliance specifications and to Figures 40, 41 and 42 on pages 10 and 11). The back side of framing for both the right hand open GCR and the right hand (or reverse) open GPF. This gas line should extend at least 2" into the control compartment at the time connection is to be made (Figure 6).

Figure 6: Shows a gas line connection with a shut-off valve in the "Off" position.

Step 3. Position the appliance into prepared framing, nailing with 6d nails through the nailing flange holes (Figure 7).

Figure 7: Depicts the appliance being positioned within the framed opening, with nails being driven through the nailing flange.

Step 4. Install the remote wall switch in a convenient location and route the 18 gage millivolt wire through the gas line access hole into the control compartment. At least 15" of wire is required in the control compartment.

Step 5. Connect either a listed 8" Type B vent system to the appliance flue collar, using a listed draft hood connector to start the vent or connect Superior's TF8 or BC8 chimney system to the appliance collar. Install remainder of vent or chimney to the outside. Minimum height of the vent or chimney and appliance should be 12 feet.

Note: Refer to the vent manufacturers installation instructions for variations of Type B venting tech-niques. If Superior's TF8 or BC8 chimney system is used, the following procedures should be followed.

Installing the Chimney System

Step 1. Before installing the complete vent or chim-ney system, it is important that the flue damper operates correctly after the vent or chimney has been installed. When installing a Type B Venting system, it is suggested that a draft hood connector (DHC) be the first vent component attached to the appliance flue collar. It may be necessary to trim or crimp the DHC skirt in order to properly adapt to the collar without interfering with the flue damper. After the first vent or chimney component has been attached to the flue collar, check the flue damper for proper operation and that there is no interference.

Step 2. Using standard construction framing tech-niques, construct opening for chimney route up through the ceiling(s) and roof or through an outside chase. Framing must maintain adequate minimum airspace clearance at all times.

CAUTION: ALLOW MINIMUM 1" (or 2")** (SEE *NOTE) CHIMNEY AIR SPACE TO COMBUSTIBLE FRAMING MEMBERS THROUGHOUT VERTICAL OR OFFSET CHIMNEY INSTALLATION.

A minimum (See **Note) air space must be re-served for all materials extending for any con-tinuous length surrounding the chimney.

Figure 10: Illustrates the required 2" air space around the BC8 chimney system.

**Note: 1" for TF8 chimney system and 2" for BC8 chimney system.

Chimney Offset 30° Through Floor or Ceiling

It may be necessary to assemble the chimney at 30° when passing through the floor or ceiling area. Use appropriate 30° angled firestop spacer as shown in Figures 34 and 35. Support the chimney at floor or ceiling penetration with a stabilizer if distance of chimney below ceiling is 10' or more. Maintain 1" (or 2")** (See **Note) minimum air space to combus-tibles from chimney sections.

Figure 34: Illustrates a 30° firestop spacer installation for a ceiling with attic above, showing 1" (or 2") minimum air space and a stabilizer.

Figure 35: Illustrates a 30° firestop spacer installation for a ceiling with room above, showing 1" (or 2") minimum air space and a stabilizer.

Step 6. Complete finished wall material and trim.

Control Module and Gas Line Hook Up

Note: The logs are packaged in their own carton and are shipped with each appliance model. The control module, burner assembly, burner grate, pilot shield, colorization rod and burner trough assembly are packaged separately in their own carton and must be ordered separately. Before gas supply piping can be connected to the gas control valve, the control mod-ule must first be installed in the appliance. If your model is not a GPF-8000, skip to Step 3.

GPF-8000 CONVERSION

Special Note: The GPF-8000 has been designed so that the control module can be installed on either the left or right side. The GPF-8000 model is shipped from the factory with the provisions to install the control module in a left open configuration (closed end or right side) (refer to specification on page 16 for stated orientation). A field conversion can be made to reverse the control module and operating glass doors. The following steps must be taken to convert the factory supplied left hand open unit to a right hand open unit:

Step 1. Switching glass doors:

The operable set of glass doors must be removed from the left side and assembled on the opposite or right side. The fixed glass panels must be removed from the right side and assembled on the left side. The top retention clips must first be removed from both doors and both fixed glass panels before they can be removed from the appliance. After doors and panels have been switched, replace the retention clips.

Step 2. Switching the door pin/switch bracket:

The pin/switch bracket that is mounted on the right door panel will have to be removed and remounted on the left door panel. To remove, remove the two (2) Phillips head screws from the pin bracket and re-mount in the same fashion on the left door panel (Figure 58, page 14). Replace screws that have been removed. Adjust the bracket so that the switch pin penetrates the slot in the control access door and contacts the switch lever. Re-tighten switch/pin bracket screws.

Note: The GPF-8000 comes with two (2) control access doors. Each access door is different and is matched to the side that corresponds to the place-ment of the control module. If, for any reason the control access doors are mounted on the wrong side, they can be switched easily.

The GPF-8000 has now been converted from a left sided model to a right sided model. The continuing steps can now be performed.

Step 3. Remove the control module securing screw from the appliance hearth flange and set aside. Open the control access door for better viewing when installing the control module. Lift up and tilt down to open.

Step 4. Remove the control module from the carton and insert the control end (facing the control access opening) into hearth opening (Figure 36). Rotate control module until level inside opening and slide to rear (Figure 36). Slide forward until front module flange engages front bracket under hearth and rear bracket slides over hearth flange. Replace control module screw to secure control module in place.

Figure 36: Illustrates the control module installation into the hearth opening, showing the front and rear brackets and the module screw.

Step 5. 1/2" Flex Connector Procedure - Attach a 1/2" flex connector (12" length, 30" length if installed on a GCR-8000R or GPF-8000R unit) with a shut off valve to the 1/2" gas supply stub, using a wrench and pipe joint compound (where required). Tighten fitting securely (Figure 37).

Figure 37: Shows a diagram of a 1/2" flex connector with a shut-off valve attached to a 1/2" fitting.

Note: Do not damage or kink the flex connector.

Step 6. Carefully bend and shape the flex gas con-nector so that a connection can be made to the gas valve. Caution should be used so as not to kink the gas connection.

Note: Check for gas leaks with soap and water solution. DO NOT USE OPEN FLAME FOR LEAK TESTING.

Step 7. Rigid Pipe Connection Procedure-Extend previously installed 1/2" NPT gas supply pipe to the gas control valve. Figures 38 and 39 illustrates the sequence of connection. Secure all fittings tightly using a wrench and pipe joint compound where necessary.

Figure 38: Illustrates a rigid pipe connection for gas supply, showing a 1/2" NPT gas supply pipe, a 1/2" x 1/2" shut off valve, a 1/2" union, and 1/2" nipples.

Figure 39: Shows a diagram of a gas valve with various connection points.

Remote Millivolt Wall Switch Wiring

Step 8. Attach one wire from the remote millivolt wall switch to the "TH" terminal on the gas control valve. Connect the other wire from the remote millivolt wall switch to the red wire (nut provided on wire) located on the door switch mounted to the control access door. Connect the blue wire, hanging in control com-partment, from flue damper switch to empty terminal on door switch (Figure 43).

Figure 43: A wiring diagram showing connections between the remote millivolt wall switch, gas valve, flue damper switch, and door switch.

CAUTION: DO NOT WIRE REMOTE WALL SWITCH TO A MAIN POWER SUPPLY. GAS VALVE WILL BE DAMAGED BEYOND REPAIR.

Step 9. Insert the venturi pilot shield into the hearth opening as illustrated in Figure 44. Center the burner grate over the pilot shield and rest grate on refractory hearth. Long side of grate must be parallel with the long side of the hearth opening.

Figure 44: Shows the venturi pilot shield, grate, burner, burner orifice, gas control module, and air shutter.

Step 10. Attach burner trough assemblies to the burner assembly with the No. 6-32 x 7/32" Phillips head screws. Secure burner troughs with screws from the underside of burner (Figure 45). It is important to orientate the burner troughs so that the white colorization material faces towards the center of the burner.

Figure 45: Illustrates the burner trough assemblies being attached with screws, showing flame enhancement strips.

Step 11. Carefully place burner, with venturi tube, into grate. Make certain that the venturi tube engages the burner orifice on the control module (Figure 44). The venturi tube guide will assist in seating the burner into the grate and center the venturi tube over the burner orifice.

Step 12. Carefully position and center the two lower logs onto the burner. It makes little difference which way the two lower logs are orientated over the burner. Position the colorization rod, from the control carton, into the two grooves found in the burner log connecting bridges (Figure 46). Place the three (3) smaller logs across the two (2) lower logs in the manner illustrated in Figure 47. The letters in the underside of the smaller logs must match the letters on the lower log to assure proper orientation.

Figure 46: Shows the colorization rod being placed into the grooves of the lower logs.

Figure 47: Illustrates the placement of the smaller logs over the lower logs, emphasizing letter alignment for proper orientation.

Step 13. Follow instructions printed on the door packaging to remove the doors and door panels from the appliance. Re-assemble doors and door panels at this time. The set of door panels (described on pages 16 and 17, items 28 and 29) are not designed to be opened.

Flame Colorization Devices

The burner assembly is equipped with special flame enhancement strips (burner trough assemblies) lo-cated around the lower burner ports. These devices, along with the colorization rod, colorize the gas flame and produce the "ember effect".

In normal operation, these devices will provide many hours of satisfactory performance. Over time, the orange color will diminish in intensity and it will be necessary to purchase a replacement rod and/or mineral fiber flame enhancement device. These de-vices are available at nominal charge from your local distributor/dealer or directly from Superior.

Cold Climate Insulation

If you live in a cold climate, seal all cracks around your appliance with non-combustible material and wher-ever cold air could enter the room. It is especially important to insulate the outside chase cavity be-tween studs and under floor on which it rests, if floor is above ground level.

Surround material must be caulked where it meets the black metal facing of the appliance to avoid air intrusion. Use non-combustible caulking material only on appliance facing to seal.

Do not place insulation materials in the gas vent or chimney system dearance spaces.

High Elevation Derating

When installing these appliances above 4,000 feet level, it is recommended that the appliance burner be derated by changing the existing orifice to a smaller one. Order and install appropriate high altitude orifice kit (Figure 48).

Figure 48: Shows examples of natural and propane orifices, labeled for derating.

Finished Wall Details

It is best to frame your appliance after it is positioned. Frame with 2 x 4's or heavier lumber. Frame in accordance with local prevailing building codes.

Note: The header may rest on the top metal spacers but must not be notched to fit around them.

To install the appliance facing flush with the finished wall position framework to accommodate the thick-ness of the finished wall (Figure 49).

Figure 49: Diagram showing a finished wall installation with a header and spacer, indicating maximum dimensions for a combustible mantel.

Non-combustible surround materials can be placed around the appliance facing to provide a flush surface between the surround materials and the fireplace facing (Figure 50).

Figure 50: Diagram illustrating the placement of non-combustible surround material for a flush finish.

A combustible mantel shelf projecting a maximum of 8" from the wall may be installed a minimum distance of 11" above the appliance opening (Figure 51).

Figure 51: Diagram showing clearance requirements for a combustible mantel shelf.

Operation

Your appliance control system is a millivolt type. It consists of a pilot burner, piezo ignition, a gas control valve and a manual ON/OFF switch. The wall switch is connected in series with a flue damper safety switch, a high temperature limit switch and a door switch. The appliance flue damper must be in the fully open position and the doors must be closed before the burner will operate (Figures 8, 9 and 57).

To obtain proper operation, it is imperative that the pilot and main burner flame characteristics are steady, not lifting or floating, and be blue in color (Figure 53).

Figure 53: Illustrates the correct pilot flame shape, showing a blue cone and a light orange tip, and indicating the pilot generator should be engulfed in the pilot flame.

Approximately the top 3/8" at the pilot generator (thermopile) should be engulfed in the pilot flame (Figure 54).

Figure 54: Shows a close-up of the pilot assembly and flame, indicating the correct pilot flame engulfment of the thermopile.
