A CAUTION
A CAUTION
Air for combustion must not be contaminated by halogen
compounds, which include fluoride, chloride, bromide and
iodide. These elements are found in aerosol sprays, deter
gents, bleaches, cleaning solvents, salts, air fresheners, and
other household products.
The operation of exhaust fans, kitchen ventilation fans,
clothes dryers, or fireplaces could create a negative air
pressure condition at the furnace. Make-up air must be
provided for the ventilation devices, in addition to that
required by the furnace.
All fuel-burning equipment must be supplied with air for combus
tion of the fuel. Sufficient air MUST be provided to insure there
will not be a negative pressure in the equipment room or space. In
addition, a positive seal MUST be made between the furnace
cabinet and the return-air duct to prevent pulling air from the
burner area and draft safeguard opening.
Combustion air requirements are determined by whether the
furnace is in an UNCONFINED or CONFINED space. A confined
space is one whose volume is less than 50 cubic ft per 1000 Btuh
of the total input rating for all appliances installed in that space.
UNCONFINED SPACE
An unconfined space must have at least 50 cubic ft for each 1000
Btuh of input for all the appliances (i.e. furnaces, clothes dryer,
water heaters, etc.) in the space.
