vented gas fireplaces with draft hoods, to draft
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.
