6. 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 10.
7. 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.
The outside air kit can be installed on either side of the
appliance.
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. 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.
WARNING!
Exhaust products of gasoline engines are hazard-
ous. The outside air must not be taken from a ga-
rage space, attic spaces, basements, or above the
roofing where other heating appliances, fans, or
chimneys exhaust or utilize air.
