Step 3
Negative
Pressure
Make-up Air
Negative Pressure warning: When negative pressure
is present, an atmospherically vented fireplace (with a
draft hood) may not function properly and it may down
draft. In the case of a gas appliance, spillage of the
combustion gases may occur. This may create a
dangerous carbon monoxide situation in the house.
The causes of negative pressure to a house can include
the following:
•Stackeffectinthebuilding.
•Exhaust only appliances (mechanically and
atmospherically vented).
•Inadequate make-up air (which is increasingly
more prevalent in new construction).
NOTE: This fireplace will operate correctly only if
adequate ventilation is provided to allow proper draft to
the fireplace system. Heat-N-Glo assumes no
responsibility for the improper performance of the
fireplace system caused by inadequate draft due to
environmental conditions, down drafts, tight sealing
construction of the structure, or mechanical exhausting
devices which create a negative air pressure within the
structure where the fireplace is located.
It is recommended that all natural venting non-air tight
gas fireplaces have outside air connected to them. It is
also recommended that the building be mechanically or
passively balanced to allow atmospherically vented
appliances, such as top 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 ANEGATIVE PRESSURE
CONDITION (LIKELYTO 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 damper assembly (found in AK-TV Kit) must be
installedto the fireplace.SeeFigure5. Attach the
damper assembly to the outer wrap of the fireplace using
sheetmetal screws
