FRESH AIR FOR
COMBUSTION AND
VENTILATION

Today’s homes are built more energy effi-
cient than ever. New materials, increased
insulation, and new construction methods
help reduce heat loss in homes. Home own-
ers 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 pos-
sible.

While it is good to make your home energy
efficient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning
appliances need fresh air for proper com-
bustion and ventilation.

Exhaust fans, fireplaces, clothes dryers, and
fuel burning appliances draw air from the
house to operate. You must provide ad-
equate fresh air for these appliances. This
will insure proper venting of vented fuel-
burning appliances.

PROVIDING ADEQUATE
VENTILATION

The following is exerpts from National Fuel
Gas Code. NFPA 54/ANSI Z223.1, Section
5.3, Air for Combustion and Ventilation.

All spaces in homes fall into one of the three
following ventilation classifications:

1. Unusually Tight Contruction; 2. Uncon-
fined Space; 3. Confined Space.

The information on pages 4 and 5 will help
you classify your space and provide ad-
equate ventilation.

 WARNING: This heater shall

not be installed in a confined
space unless provisions are pro-
vided for adequate combustion
and ventilation air. Read the fol-
lowing instructions to insure
proper fresh air for this and other
fuel-burning appliances in your
home.
