properly. If the home experiences negative pressure
or is likely to experience negative pressure,
connection to an outside air source is mandatory.
Installing Optional Outside Make-up Air:
This unit is equipped to accept outside air. By using
outside make-up air, the amount of room air used for
combustion will be reduced. It is recommended that
an AK-TV air kit be used with this appliance.
WARNING: IN A NEGATIVE PRESSURE
CONDITION (LIKELY TO OCCUR IN
NEW HOMES THAT DO NOT HAVE ADEQUATE
MAKE-UP AIR) THE OUTSIDE AIR KIT MUST
BE INSTALLED TO OBTAIN PROPER
PERFORMANCE AND TO HELP PREVENT
SPILLAGE OF COMBUSTION GASES.
A 4-inch side collar/damper (found in AK-TV Kit)
must be installed on the fireplace by attaching the
side collar to the outer wrap of the fireplace at the
right-hand rear corner using sheetmetal screws.
See Figure 4. Attach one end of a 4-inch flexible air
duct (not provided in the AK-TV Kit) to the side collar
and the other end of the duct to the make-up air
termination cap. Use plastic tie straps to secure the
ends of the flex duct to each collar.
