Inspecting the Venting System
This appliance venting system is designed and con- structed 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 the window frame assembly (Refer to Page 10). Using a flashlight, check the area above the baffle in the combustion dome. Clean if necessary.
Test Chimney Draw
A "Chimney Draw" test must be made before the instal- lation 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 ad- equate draft has been determined and rectified.

First Firing
Remove window frame assembly before lighting. Upon completing the gas line connection, a small
amount of air will be trapped in the line. When first lighting the unit with 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 appli- ance will not require purging.
When lit for the first time, the appliance will emit a slight odor for awhile. This is due to paint and lubricants used in the manufacturing process. After each lighting, vapor may condense and fog the glass; this moisture disap- pears within a few minutes of burning.
