Cold Climate Insulation

For cold climate installations, seal all cracks around your appliance with noncombustible material and wherever cold air could enter the room. It is especially important to insulate outside chase cavity between studs and under floor on which appliance rests, if floor is above ground level. Gas line holes and other openings should be caulked or stuffed with unfaced fiberglass insulation.

If the fireplace is being installed on a cement slab in cold climates, a sheet of plywood or other raised platform can be placed underneath to prevent cold transfer to the fireplace and into the room. It also helps to sheetrock inside surfaces and tape for maximum air tightness

and caulk firestops.

LOCATION

In selecting the location, the aesthetic and functional use of the appliance are primary concerns. However, vent system routing to the exterior and access to the fuel supply are also important.

Due to high temperatures, the appliance should be located out of traffic and away from furniture and draperies (Figure 3).

Enraisondestempératuresélevées,l’appareil devrait être installé dans un endroit où il y a peu de circulation et loin du mobilier et des tentures (Figure 3).

The location should also be free of electrical, plumbing or other heating/air conditioning ducting.

These direct-vent appliances are uniquely suited for installations requiring a utility shelf positioned directly above the fireplace. Utility shelves like these are commonly used for locat-ing television sets and decorative plants.

Be aware that this is a heat producing appliance. Objects placed above the unit are exposed to elevated temperatures.

Do not insulate the space between the appliance and the area above it (see Figure 8 on Page 8).

The minimum height from the base of the appliance to the underside of combustible materials used to construct a utility shelf in this fashion is shown in Figure 8 on Page 8.

The appliance should be mounted on a fully supported base extending the full width and depth of the unit. The appliance may be located on or near conventional construction materials. However, if installed on combustible materials, such as carpeting, vinyl tile, etc., a metal or wood barrier covering the entire bottom surface must be used.

MINIMUM CLEARANCES TO COMBUSTIBLES

The appliance is approved with zero clearance to combustible materials on all sides (as detailed in Table 5), with the following exception: When the unit is installed with one side flush with a wall, the wall on the other side of the unit must not extend beyond the front edge of the unit. In addition, when the unit is recessed, the side walls surrounding the unit must not extend beyond the front edge of the unit (see Figure 3).

*Note: 3 in. (75 mm) above any horizontal/inclined vent component.

**Note: See Page 9, Step 1 for clearance requirements to the nailing flange located at each side of the unit and any screw heads adjacent to it.

The appliance should be mounted on a fully supported base extending the full width and depth of the unit. The appliance may be located on or near conventional construction materials. However, if installed on combustible materials, such as carpeting, vinyl tile, etc., a metal or wood barrier covering the entire bottom surface must be used.

Shelf Height

To provide for the lowest possible shelf surface, the venting attached to the top vent should be routed in a way to minimize obstructions to the space above the appliance. Do not insulate the space between the appliance and the area above it (see Figure 8). The minimum height from the base of the appliance to the underside of combustible materials used to construct a utility shelf in this fashion is shown in Figure 8.

Wall Finishes / Surrounds / Mantels

Note: Combustible wall finish materials and/or surround materials must not be allowed to encroach the area defined by the appliance front face (black sheet metal). Never allow combustible materials to be positioned in front of or overlapping the appliance face. See Figure 10 and Figure 53 on Page 28.

Non-combustible materials, such as surrounds and other appliance trim, may be installed on the appliance front face with these exceptions: they must not cover any portion of the removable glass panel.

Vertical installation clearances to combustible mantels vary according to the depth of the mantel. See Figure 9. Mantels constructed of noncombustible materials may be installed at any height above the appliance opening.

NOTE: We recommend the use of high temperature paint (rated 175° F or higher) on the underside of the mantel.

WARNING

Failure to position the parts in accordance with these diagrams or failure to use only parts specificallyapprovedwiththisappliance may result in property damage or personal injury.

AVERTISSEMENT

Risque de dommages ou de blessures si les pièces ne sont pas installées conformément à ces schémas et ou si des pièces autres que celles spécifiquement approuvéesaveccetappareilsont utilisées.

DETAILED INSTALLATION STEPS

The appliance is shipped with all gas controls and components installed and pre-wired.

1.Remove the shipping carton, exposing the front glass door on the valve access side.

2.Using a Phillips screwdriver, unfasten two (2) screws located at the top of the glass frame (see Figure 49). Tilt the top of the glass frame away from the unit. Lift it carefully off the bottom door track and set the door aside, protecting it from inadvertent damage.

TYPICAL INSTALLATION SEQUENCE

The typical sequence of installation is outlined below. However, each installation is unique and may result in variations to the steps described.

See the Page numbers references in the following steps for detailed procedures.

Step 1. (Page 9) Construct the appliance framing. Position the appliance within the framing and secure with nailing brackets.

Step 2. (Page 11) Route gas supply line to the right side.

Step 3. (Page 12) Install the vent system and exterior termination.

Step 4. (Page 21) Field Wiring

a.Millivolt and Electronic Appliances – The operating control switch is factory installed.

b.Electronic Appliances – Connect 120 Vac electrical power to the appliance receptacle.

Step 5. (Page 22) Remove glass door assembly.

Step 6. (Page 22) Make connection to gas supply.

Step 7. (Page 23) Verifying appliance operation.

Step 8. (Page 24) Install ceramic panels, logs and glowing embers.

Step 9. (Page 26) Install glass door assembly.

Step 10. (Page 26) Adjust burner to ensure proper flame appearance.

Step 11. (Page 29) Attach Safety in Operation Warnings.

Step 1. Framing

Frame these appliances as illustrated in Figure 12 on Page 10, unless the appliance is to be installed in a corner. See Figure 13 on Page 11 for corner framing installations. All framing details must allow for a minimum clearance to combustible framing members as shown in

Table 5 on Page 8.

If the appliance is to be elevated above floor level, a solid continuous platform must be constructed below the appliance.

Headers may be in direct contact with the appliance top spacers but must not be supported by them or notched to fit around them. All construction above the appliance must be self-supporting, DO NOT use the appliance for structural support.

The fireplace should be secured to the side framing members using the unit's nailing flanges - one top and bottom on each side of the fireplace front (see Figure 11). Use 8d nails or their equivalent.
