AIR FOR COMBUSTION
AND VENTILATION

-
Today’s homes are built more energy efcient
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
efcient, 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, replaces, 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
proper venting of vented fuel-burning appli-
ances.
The following are excerpts from National Fuel
Gas Code. ANSI Z223.1/NFPA 54, Section
5.3, Air for Combustion and Ventilation.
All spaces in homes fall into one of the three
following ventilation classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
The information on pages 6 through 8 will help
you classify your space and provide adequate
ventilation.
4. Check installation of brick liners. Brick
liners are in four pieces: 2 sides, 1 back
and 1 top.
5. Place hood under top edge of rebox
opening. Use 3 screws from hardware kit
to mount hood to rebox (see Figure 3).
