First Firing
Upon completing the gas line connection, a small
amount of air will be trapped in the line. When first
lighting the unit with the pilot light, it will take a few
minutes to purge the trapped air. Once purging is
complete, the pilot and burner will light and operate as
indicated in the instruction manual. Subsequent
lightings of the appliance will not require purging.
When lit for the first time, the appliance will emit a slight
odor for an hour or two. This is due to paint and lubri-
cants used in the manufacturing process. After lighting,
vapor may condense and fog the glass; this moisture
disappears within a few minutes of burning.
Inspecting the Venting System
This appliance venting system was designed and
constructed to develop a positive flow adequate to
remove flue gases to the outside atmosphere.
Any foreign objects in the venting system, except those
designed specifically for the venting system, may cause
spillage of flue gases.
To inspect the venting system, make sure the main gas
valve is off. Remove glass frame (See Window Frame
Assembly Removal Section). Using a flashlight, check
the area above the baffle in the combustion dome.
Clean if necessary.
Flame Characteristics
It is important to periodically perform a
visual check of the pilot and the burner
flames. Compare them to the illustrations
below (Figs. 15, 16, 17). If any of the flames appear
abnormal call a service person.

Test Chimney Draw
A "Chimney Draw" test must be made before the
installation is complete.
1. Close all doors and windows in the home and start
exhaust fans in the kitchen and bathroom.
2. Light unit and operate for 5 minutes.
3. Hold an ignited match, cigarette, or smoke match in
front of the unit. Refer to Figure 17 for location of the
draft hood opening.
4. Check to make sure smoke from the match, cigarette
or smoke match is drawn into the fireplace. If it is
not, turn the unit off and check for causes creating
the lack of adequate draft.
Do not operate the unit until lack of
adequate draft has been determined and
rectified.
