2.Adjust the gas input rate per the installation instructions. Low gas input rate causes low vent gas temperatures, caus- ing condensation and corrosion in the furnace and/or vent- ing 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. (102 mm) round vent elbow is supplied with the furnace. A 5 in. or 6 in. (127 or 152 mm) vent connector may be required for some model furnaces. A field-supplied 4 in. to 5 in. (102 to 127 mm) or 4 in. to 6 in. (102 mm to 152 mm) sheet metal increaser fitting is required when 5 in. or 6 in. (127 or 152 mm) vent connector is used. See Fig. 35-47 Venting Orientation for approved vent configurations.
