Figure 11 - Checking for Spillage
Check area along entire top edge of
fireplace opening. Smoke or flame should
be drawn into appliance opening.
CHECKING FOR PROPER VENTING
After completing and checking the electrical, gas and vent connec-
tions, follow the lighting instructions and allow the main burner to
run for approximately 5 minutes. Hold a lit match or cigarette near
top edge of fireplace opening and play it along entire length of the
opening (see Figure 11). Proper venting should tend to draw flame
or smoke into appliance. Improper venting or escaping of spillage
of burned gas, is indicated when match flickers or goes out. Smoke
from a cigarette will also tend to disperse away from the appliance.
If appliance is found to be improperly venting, shut it off and notify
your installer or a qualified service agency to inspect venting system.
NOTICE: This appliance is equipped with a vent safety
shutoff switch which will shut down appliance in case
of a venting problem. Do not bypass vent safety switch.
If appliance should shut down, contact a qualified
installer, service agency, or your gas supplier to have
vent inspected before operating.
