Furnace must be located or physically protected from pos- sible damage by a vehicle.
8.If the furnace is to be suspended from the floorjoists in a base- ment or a crawl space or the rafters in an attic, it is necessary to use steel pipe straps or an angle iron frame to attach the furnace. These straps should be attached to the furnace with sheet metal screws and to the rafters or joists with bolts. The preferred method is to use an angle iron frame bolted to the rafters or joists.

Clean outside air is provided for combustion. This is to mini- mize the corrosive effects of adhesives, sealers and other
construction materials. It also prevents the entrainment of
drywall dust into combustion air, which can cause fouling and plugging of furnace components.

CARBON MONOXIDE POISONING HAZARD.
Failure to follow safety warnings exactly could result in serious injury, death, or property damage.
Do NOT operate furnace in a corrosive atmosphere containing chlorine, fluorine or any other damaging chemicals, which could shorten furnace life.
•The air temperature rise is within the rated rise range on the furnace rating plate, and the firing rate has been set to the rating plate value.
•The filters used to clean the circulating air during the
construction process must be either changed or thoroughly cleaned prior to occupancy.
