COLD CLIMATE INSULATION

For cold climate installations, seal all cracks around the 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 the 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 conducting cold up 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. Consideration should be given to traffic ways, furniture, draperies, etc., due to elevated surface temperatures (Figure 4 ). 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 locating television sets and decorative plants. Be aware that this is a heat producing appliance. Objects placed above the unit are exposed to elevated temperatures.

To provide for the lowest possible shelf surface use the alternate rear vent outlet with attached venting routed in a way to minimize obstructions to the use of the space above the appliance. Do not insulate the space between the appliance and the area above it. See Figure 9. 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 the Table in Figure 9.

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.

DETAILED INSTALLATION STEPS

The appliance is shipped with all gas controls and components installed and pre-wired. Remove the shipping carton, exposing the front glass door. Remove the top and bottom louvered control panel per instructions on Page 27 (see

Control Compartment Access / Louver Panel Instructions). Remove the cardboard from underneath the pressure relief plates, in area behind top louver panel (see Figure 11). Open the two latches (located under the firebox floor) securing the glass door. Remove the door by tilting it outward at the bottom and lifting it up. Set the door aside protecting it from inadvertent damage. See Figure 55 on Page 31.

TYPICAL INSTALLATION SEQUENCE

The typical sequence of installation follows, however, each installation is unique resulting in variations to those described.

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

Step 1. (Page 10) Construct the appliance framing. Position the appliance within the framing and secure with nailing brackets.

Step 2. (Page 10) Route gas supply line to appliance location.

Step 3. (Page 13) Install the vent system and exterior termination.

10

Step 4. (Page 25) Field Wiring

a.Millivolt Appliances – Install the operating control switch (not factory provided) and bring in electrical service line for forced air circulating blower (optional equipment).

b.Electronic Appliances – Field wire and install operating control switch.

Step 5. (Page 25) Install blower kit (optional equipment).

Step 6. (Page 26) Make connection to gas supply.

Step 7. (Page 27) Checkout appliance operation. Step 8. (Page 28) Install the logs, decorative

volcanic stone and glowing embers.

Step 9. (Page 31) Install glass door frame assembly.

Step10.(Page31) Adjustburnertoensureproper flame appearance.

Step 11. (Page 32) Install the hoods.

Step 1. FRAMING

Frame these appliances as illustrated in Figure 14 on Page 11, unless the appliance is to be installed in a corner. See Figure 15 on Page 12 for corner framing installations. All framing details must allow for a minimum clearance to combustible framing members as shown in

Table 8 on Page 9.

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

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.

Thefireplaceshouldbesecuredtothesideframing members using the unit's nailing flanges - one top and bottom on each side of the fireplace front. See Figure 12. Use 8d nails or their equivalent.
