causing condensation and corrosion in the furnace and/or venting system. Derating is permitted only for altitudes above 2000 ft

3.Adjust the air temperature rise to the midpoint of the rise range or slightly above. Low air temperature rise can cause low vent gas temperature and potential for condensation problems.

4.Set the thermostat heat anticipator or cycle rate to reduce short cycling.

Air for combustion must not be contaminated by halogen compounds which include chlorides, fluorides, bromides, and iodides. These compounds are found in many common home products such as detergent, paint, glue, aerosol spray, bleach, cleaning solvent, salt, and air freshener, and can cause corrosion of furnaces and vents. Avoid using such products in the combustion-air supply. Furnace use during construction of the building could cause the furnace to be exposed to halogen compounds, causing premature failure of the furnace or venting system due to corrosion.

Vent dampers on any appliance connected to the common vent can cause condensation and corrosion in the venting system. Do not use vent dampers on appliances common vented with this furnace.

ADDITIONAL VENTING REQUIREMENTS

A 4 in. round vent elbow is supplied with the furnace. A 5 in. or 6 in. vent connector may be required for some model furnaces. A field-supplied 4 in. to 5 in. or 4 in. to 6 in. sheet metal increaser fitting is required when 5 in. or 6 in. vent connector is used. See Fig. 36-48 Venting Orientation for approved vent configurations.

See Venting Notes after Fig. 48.
