DAMPER AND OUTSIDE AIR CONTROLS

This appliance is fitted with a manually con- trolled vent damper. The vent damper should be closed when the appliance is not in use to prevent cold air from entering the home through the venting system. The damper is controlled through the use of a control lever located within the appliance opening at the top center in front of the firebox lintel (see Figure 5 ). The control lever snaps into place at either extreme of its range of motion. When locked in position all the way to the right, the damper is open. When locked in position all the way to the left, the damper is closed.

2.When lit for the first time, this appliance will emit a slight odor for an hour or two. This is due to the “burn-in” of internal paints and lubricants used in the manufacturing process.

3.Keep lower control compartment clean by vacuuming or brushing at least twice a year. More frequent cleaning may be required due to excessive lint from carpeting, bedding materi- als, etc. It is important that control compart- ments, burners and circulating air passage- ways of the appliance be kept clean.

4.Always turn off gas to the pilot (millivolt appliances) before cleaning. Before re-light- ing, refer to the lighting instructions in this manual. Instructions are also found on a pull- out panel located on the floor of the appliance.

5.Always keep the appliance area clear and free from combustible materials, gasoline and

other flammable liquids.

7.Clean the optional glass doors only when necessary. Wipe surface with clean, damp- ened, soft cloth. Follow with dry, soft towel as desired. Take care not to scratch the glass surface.
