VENTING INSTALLATION
Continued
Some codes areas allow the use of existing B-type vent systems if
the system is at or above the recommended diameter of the flue, in
this case 6".
The flue connection must be made using listed B-type connectors
and the existing system must be code inspected for damage and
proper installation.
It is not recommended that this appliance be common vented with
an existing gas burning appliance.
NOTE:
Before connecting this appliance to an existing vent system
consult with your local architect, planner or building official.

Figure 11 - B-Vent Terminations
Figure 12 - Checking for Spillage
Check this 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 electrical, gas and vent connections,
follow the lighting instructions and allow main burner to run for ap-
proximately 5 minutes. Hold a lighted match or cigarette near the top
edge of fireplace opening and play it along entire length of opening
(see
Figure 12
).
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. 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 the venting
system.
WARNING: This appliance must be properly con-
nected to a system and must not be connected to a
chimney flue servicing a separate solid fuel burning
appliance.
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 appliance should shut down, con-
tact a qualified installer, service agency or your gas
supplier to have the vent inspected before operating.
