SELECTING LOCATION

Continued

• Do not locate appliance close to where gasoline or other flammable liquids may be stored. The appliance must be kept clear and free from combustible materials.

• Do not use this appliance if any part has been under water. Immediately contact a local service technician to examine the appliance and to replace any part(s) of the control ignition system and other related components that have been submerged under water.

PRE-INSTALLATION

PREPARATION

CAUTION: Do not block required air spaces with insulation or any other material. Do not obstruct the effective opening of the appliance with any type of facing material.

CLEARANCES TO COMBUSTIBLES

Minimum clearances to combustibles for the fireplace are:

• Back and Sides of Fireplace . . . . . . . . . . . . 0"

• Floor . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0"

• Perpendicular Wall . . . . . . . . . . . . . . . . . . . 6"

VENT TERMINATION CLEARANCES

The final position of your fireplace depends on the location of the vent termination in relation to the clearances that must be observed as shown in

Figure 5 on page 6.

The vent system serves as the “chimney” as well as the combustion air supply (air intake). The horizontal run must have a rise of 1/4" (.6 cm) for every 12" (30.48 cm) of horizontal run towards the termination. The maximum horizontal run depends on the vertical rise from the fireplace adapter collar to the vent termination (see table below).

VERTICAL

0 to

HORIZONTAL

1 ft (30.48 cm)

1 ft (30.48 cm) to 4 ft (121.92 cm)

2 ft (60.96 cm) to 8 ft (243.84 cm)

3 ft (91.44 cm) to 12 ft (365.76 cm)

4 ft (121.92 cm) to 16 ft (487.68 cm)

5 ft (152.40 cm) to 15 ft (457.20 cm)

6 ft (182.88 cm) to 14 ft (426.72 cm)

7 ft (213.36 cm) to 13 ft (396.24 cm)

8 ft (243.84 cm) to 12 ft (365.76 cm)

FRAMING

Once the final location has been determined, observing height clearances for vent termination, you may construct framing using dimensions shown in

Figures 3 and 4, depending on your installation.

If the appliance is to be installed directly on carpeting, tile (other than ceramic) or any combustible material other than wood flooring, the appliance must be installed on a metal or wood panel extending the full width and depth of the appliance.
