CHECKING FOR PROPER VENTING
After completing and checking electrical, gas
and vent connections, follow the lighting in-
structions and allow the main burner to run for
approximately 5 minutes. Hold a lighted match
near the top edge of fireplace opening and play
it along entire length of opening (see Figure 21,
page 17). Proper venting should tend to draw
the flame or smoke into the appliance. Improper
venting or escaping of spillage of burned gas, is
indicated when the match flickers or goes out.
If the appliance is found to be improperly
venting, shut it off and notify your installer
or a qualified service agency to inspect the
venting system.
NOTICE: This appliance is
equipped with a vent safety
shutoff switch which will shut
down the appliance in the case of
a venting problem. Do not bypass
the vent safety switch. If the appli-
ance should shut down, contact a
qualified installer, service agency
or your gas supplier to have the
vent inspected before operating.
