Page 9: Cold Climate Insulation
COLD CLIMATE INSULATION If you live in a cold climate, seal all cracks around your appliance, and wherever cold air could enter the room, with noncombustible material. It is especially important to insulate the outside chase cavity between the studs and under the floor on which the appliance rests, if the floor is above ground level. -
Page 10: Mantel Clearances
CLEARANCES CLEARANCES TO COMBUSTIBLES Follow these instructions carefully to ensure safe installation. Failure to follow in struc tions exactly can create a fi re hazard. The appliance cannot be installed on a carpet, tile or other combustible material other than wood fl ooring. If installed on carpet or vinyl fl ooring, the appliance shall be installed on a metal, wood or noncombustible material panel ex tend ing full width and depth of the appliance. -
Page 11: Securing Fireplace To Floor Or Framing
The fireplace must be secured to the floor and/or to framing studs as shown in Figure 6. Use two (2) wood screws or masonry/ concrete screws to secure fireplace to the floor. Use four (4) screws to attach fireplace to framing. The side nailing flanges are 1/2"... -
Page 12: Installation Information
INSTALLATION INFORMATION FINISHING MATERIAL NOTE: Any remote wiring (i.e. remote control, wall switch, and optional fan) must be done prior to fi nal fi nishing to avoid costly reconstruction. Only noncombustible materials (i.e. brick, tile, slate, steel, or other materials with a UL fire rating of Zero) may be used to cover the black painted face of the appliance. -
Page 13: Vent Installation
Horizontal sections of this vent system require a minimum of 3" clearances to combustibles at the top of the fl ue and 1" clearance at the sides and bottom until the fl ue penetrates the outside wall. A minimum 1" clearance all around the fl ue is acceptable at this point of penetration. -
Page 14: Installation Planning
VENT INSTALLATION INSTALLATION PLANNING There are two basic types of direct-vent installation: • Horizontal Termination • Vertical Termination It is important to select the proper length of vent pipe for the type of termination you choose. It is also important to note the wall thickness. - Page 15 FOR HORIZONTAL TERMINATION Vent Terminal Figure 8 - Horizontal Vent Termination Location MINIMUM DISTANCES A = Clearance above the grade, a veranda, porch, deck, or balcony [*12" (305mm) minimum]. B = Clearance to window or door that may be opened [*12" (305mm) minimum]. C = Clearance to permanently closed window [*minimum 12"...

Page 17: Vertical/Horizontal Termination
VERTICAL/HORIZONTAL TERMINATION CONFIGURATIONS Since it is very important that the venting system maintain its balance between the combustion air intake and the flue gas exhaust, certain limitations as to vent configurations apply and must be strictly adhered to. The Vent Graph, showing the relationship between vertical and horizontal side wall venting, will help to determine the vari- ous dimensions allowable. - Page 18 VENT INSTALLATION VERTICAL/HORIZONTAL TERMINATION CONFIGURATIONS (continued) • If a 90° elbow is used in the horizontal vent run (level height maintained) the horizontal vent length is reduced by 36". See Figures 11 and 12, page 17. This does not apply if the 90°...
-
Page 19: Below Grade Installation
BELOW GRADE INSTALLATIONS When it is not possible to meet the required vent terminal clearances of 12" above grade level, a snorkel kit is recommended. It allows installation depth down to 7" (178mm) below grade level. The 7" (178mm) is measured from the center of the horizontal vent pipe as it penetrates through the wall. -
Page 20: Vertical Through-The-Roof Applications
VENT INSTALLATION VERTICAL (THROUGH-THE-ROOF) APPLICATIONS This gas fireplace has been approved for, • Vertical installations up to 40' (12m) in height. Up to a 10' (3m) horizontal vent run can be installed within the vent system using a maximum of two 90° elbows. See Figure NOTE: Horizontal sections of this vent system require a minimum of 3"... -
Page 21: Installation For Vertical Termination
INSTALLATION FOR VERTICAL TERMINATION 1. Determine the route your vertical venting will take. If ceiling joist, roof rafters or other framing will obstruct the venting system, consider an offset. See Figure 20 to avoid cutting load bearing members. For optimal flame appearance, a restrictor disk is necessary on straight vertical runs of 10' of more. - Page 22 VENT INSTALLATION 3. Cut a hole in the roof using the locating hole as a center point. (Cover any exposed open vent pipes before cutting hole 1/ 2 in roof). The 10 "x10 " (241mm x 241mm) hole must be measured on the horizontal. Actual length may be larger depending on the pitch of the roof.
