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 ﬂ oor on which the appliance rests, if ﬂ oor is above ground level. Gas line holes and other openings should be caulked or stuffed with unfaced ﬁ berglass insulation. If the ﬁ replace 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 ﬁ restops.

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 trafﬁ c ways, furniture, draperies, etc., due to elevated surface temperatures (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 ﬁ replace. 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 8. The mini-

mum 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 8.

MINIMUM CLEARANCES TO COMBUSTIBLES

Appliance and Vent Clearances

Hearth Extension - A hearth extension is not required with this appliance. If a hearth extension is

used, do not block the lower control compartment door. Any hearth extension used is for appearance only and does not have to conform to standard hearth extension installation requirements.

Wall Finishes / Surrounds / Mantels

Note: Combustible wall ﬁ nish materials and/or surround materials must not be allowed to encroach the area deﬁ ned by the appliance front face (black sheet metal). Never allow combustible materials to be positioned in front of or overlapping the appliance front face. See Figure 56 on Page 31.

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 or louvers.

Vertical installation clearances to combustible mantels vary according to the depth of the mantel. See Figure 7. Mantels constructed of non-combustible materials may be installed at any height above the appliance opening; however, do not allow anything to hang below the hood.

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.

Step 4. (Page 25) Field Wiring

a. Millivolt Appliances – The operating control

switch is factory installed.

b. Electronic Appliances – Connect 120 VAC

electrical power to the appliance receptacle.

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

equipment).

Step 6. (Page 26) Make connection to gas sup-

ply.

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

and glowing embers.

Step 9. (Page 30) Install glass door frame as-

sembly.

Step 10. (Page 30) Adjust burner to ensure proper

ﬂ ame appearance.

Step 11. (Page 31) Install the hood.

Step 1. FRAMING

Frame these appliances as illustrated in Figure 13 on Page 11, unless the appliance is to be installed in a corner. See Figure 14 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 ﬂ oor 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 ﬁ t around them. All construction above the appliance must be self supporting. DO NOT use the appliance for structural support.

The ﬁ replace should be secured to the side framing members using the unit's nailing ﬂ anges - one top and bottom on each side of the ﬁ replace front. See Figure 11. Use 8d nails or their equivalent.
