B. Outside Air

A source of air (oxygen) is required in order for combustion to take place. Whatever air is consumed by the fire must be replaced through cracks around windows, under doors, etc. Most newly constructed houses or existing homes fitted with tightly sealed doors and windows are relatively air tight. In this case, an outside air source must be made available to feed combustion air from outside the home.

An outside air control handle allows you control of the out- side air inlet if your fireplace is equipped with this option. Use of outside air for combustion is highly recommended to conserve heated air within the structure and to provide make up air to keep the fireplace venting properly.

This fireplace will operate correctly only if adequate ventila- tion is provided to allow proper draft to the fireplace sys- tem.

See Figure 9.1 for location and operation.

CAUTION

Outside air control handle is HOT. Adjust before lighting fire.

C. Clear Space Near the Fireplace

Combustible materials must not be stored on the hearth ex- tension. Room furnishings such as drapes, curtains, chairs or other combustibles must be at least 4 ft (1.22 m) from the open front of the fireplace.

D. Flue Damper

The flue damper must be in full open position, and is oper- ated by moving the handle up toward the top of the fireplace. Before lighting the fire, verify this by looking up from the in- side of the fireplace. Always operate this fireplace with the damper fully open. Please note: Down drafts, obstructions, damaged or poor (wet) fuels can cause smoke spillage.

See Figure 9.1 for location and operation.

WARNING

Asphyxiation Risk

Fire Risk

•Open damper to operate fireplace.

Closed damper will over-fire fireplace and prevent venting of combustion gases.

E. Firescreen

A firescreen is always provided to control sparks. It must be closed whenever the fireplace is in use. Glass doors or firescreens must not be used to hold burning material in- side the fireplace. Only those glass doors specifically tested and listed for use with the specific fireplace model should be used. Screens should be closed when the glass doors are closed.

WARNING

Fire Risk

•Close firescreen when burning fireplace.

•Do not use firescreen or glass doors to hold burning material in fireplace.

Glass may break or burning material may roll out.

F. Glass Doors

Most efficient fireplace operation using glass doors is with the doors open. When the doors are open the screen must be closed. Only Hearth & Home Technologies glass doors may be used. See Figure 9.2 for proper glass door opera- tion.
