BCBR36 B-VENT GAS APPLIANCE
5. Checking the Vent System
Test the venting system periodically to assure proper
operation. This can be done with a match while the
appliance is operating.
Hold a lighted match at the top edge of the appliance
opening. If the flames and smoke remain upright,
ventilation is acceptable. If the flames and smoke are
drawn into the appliance, this means ventilation is
good. If the flames and smoke are forced away from
the appliance, this may indicate a ventilation blockage
or down draft resulting in gas spillage into your home.
If this occurs, turn off the appliance and do not burn it
until it has been inspected by a qualified service
person.
If you have installed optional doors, close the doors
and conduct the test following the same instructions
above. See Figure 9.
6. Outside Air Kit Installation
An outside air kit is available as an optional feature
with this appliance. An outside air kit helps to decrease
the amount of room air taken, by utilizing outside air
for combustion. It is strongly recommended that it be
installed. An outside air kit can be installed only on the
left side.
It is recommended to utilize the shortest duct run to
optimize the performance of the outside air kit. The
outside air kit inlet thimble should be positioned at least
four feet above the ground level, in a manner that will
not allow snow, leaves, etc. to block the inlet.
To install the outside air kit, refer to the installation
instructions provided with the kit.
Note:
The outside air kit can terminate at any level
with the exception that it must terminate at least one
foot below the vent termination cap.

Testing Ventilation
WARNING!
Exhaust products of gasoline engines are haz-
ardous. The outside air must not be taken from
a garage space, attic spaces, basements, or
above the roofing where other heating appli-
ances, fans, or chimneys exhaust or utilize air.
