WARNING: This heater shall
not be installed in a confined
space or unusually tight con-
struction unless provisions are
provided for adequate combus-
tion and ventilation air. Read the
following instructions to insure
proper fresh air for this and
other fuel-burning appliances
in your home.
Today’s homes are built more energy efficient
than ever. New materials, increased insulation
and new construction methods help reduce
heat loss in homes. Home owners weather
strip and caulk around windows and doors
to keep the cold air out and the warm air in.
During heating months, home owners want
their.homes.as.airtight.as.possible.
While.it.is.good.to.make.your.home.energy.
efficient, your home needs to breathe. Fresh
air.must.enter.your.home..All.fuel-burning.ap-
pliances.need.fresh.air.for.proper.combustion.
and.ventilation.
Exhaust fans, fireplaces, clothes dryers and
fuel burning appliances draw air from the
house to operate. You must provide adequate
fresh air for these appliances. This will insure

PROVIDING ADEQUATE
VENTILATION
The following are excerpts from
National Fuel
Gas Code, ANSI Z223.1/NFPA 54, Air for
Combustion and Ventilation.
All.spaces.in.homes.fall.into.one.of.the.three.
following ventilation classifications:

2. Unconfined Space
3. Confined Space

ventilation.
Unusually Tight Construction
The air that leaks around doors and windows
may.provide.enough.fresh.air.for.combustion.
and ventilation. However, in buildings of un-
usually tight construction, you must provide
additional.fresh.air.
Unusually tight construction is defined as
construction where:
a. walls and ceilings exposed to the out-
side atmosphere have a continuous
water vapor retarder with a rating of one
perm (6 x 10
-11
kg per pa-sec-m

) or less
with openings gasketed or sealed and
b. weather stripping has been added on
