ing occupants to gas combustion products that could include
carbon monoxide.
If this furnace is to be installed in the same space with other
gas appliances, such as a water heater, ensure there is an ad-
equate supply of combustion and ventilation air for the other
appliances. Refer to the latest edition of the National Fuel
Gas Code NFPA 54/ANSI Z223.1 or CAN/CSA B149.1-15 Instal-
lation Codes or applicable provisions of the local building
codes for determining the combustion air requirements for
the appliances.
Most homes will require outside air be supplied to the fur-
nace area by means of ventilation grilles or ducts connecting
directly to the outdoors or spaces open to the outdoors such
as attics or crawl spaces.
