!CAUTION

UNIT DAMAGE HAZARD

This gas furnace may be used for construction heat provided that:

-The furnace is permanently installed with all electrical wiring, piping, air filters, venting and ducting installed according to these installation instructions. A return air duct is provided, sealed to the furnace casing, and terminated outside the space containing the furnace. This prevents a negative pressure condition as created by the circulating air blower, causing a flame rollout and/or drawing combustion products into the structure.

-The furnace is controlled by a thermostat. It may not be “hot wired” to provide heat continuously to the structure without thermostatic control.

-Clean outside air is provided for combustion. This is to minimize 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.

-The temperature of the return air to the furnace is maintained between 55_F (13_C) and 80_F (27_C), with no evening setback or shutdown. The use of the furnace while the structure is under construction is deemed to be intermittent operation per our installation instructions.

-The air temperature rise is within the rated rise range on the furnace rating plate, and the firing rate has been set to the nameplate value.

-The filters used to clean the circulating air during the construction process must be either changed or thoroughly cleaned prior to occupancy.

-The furnace, ductwork and filters are cleaned as necessary to remove drywall dust and construction debris from all HVAC system components after construction is completed.

-After construction is complete, verify furnace operating conditions including ignition, input rate, temperature rise and venting, according to the manufacturer’s instructions.

WARNING

 

 

FIRE OR DEATH HAZARD

 

 

Failure to follow this warning could result in property

 

 

damage, personal injury, or death.

 

 

Do not install furnace on its back. (See Fig. 16.) Safety

 

 

control operation will be adversely affected. Never connect

 

 

return-air ducts to back of furnace.

 

 

 

 

 

The furnace and its return air system shall be designed and

 

installed so that negative pressure created by the air circulating

 

fan cannot affect another appliance’s combustion air supply or act

 

to mix products of combustion with circulating air, and that the

 

air circulating fan of the furnace, if installed in an enclosure

 

communicating with another fuel-burning appliance not of the

 

355CAV

direct-vent type, shall be operable only when any door or panel

covering an opening in the furnace fan compartment or in a return

 

air plenum on ducts is in the closed position.

CAUTION

 

 

 

 

UNIT DAMAGE HAZARD

Failure to follow this caution may result in minor property or unit damage.

If these furnaces are installed in an unconditioned space where ambient temperatures may be 32_F (0_C) or lower, freeze protection measures must be taken. See Condensate Drain Protection section and Fig. 17.

32oF MINIMUM INSTALLED AMBIENT OR FREEZE PROTECTION REQUIRED

A93058

Fig. 17 - Freeze Protection

Furnace Location Relative to Cooling Equipment

The cooling coil must be installed parallel with or on downstream side of furnace to avoid condensation in heat exchanger. When installed parallel with a furnace, dampers or other means used to control flow of air shall be adequate to prevent chilled air from entering furnace. If dampers are manually operated, they must be equipped with a means to prevent operation of either unit unless damper is in full-heat or full-cool position.
