PSC Motor Air Flow

Heating – set the blower motor speed to give the specied
air temperature rise. Fan on time after the burner starts is
fixed by the nrgMax control. Fan off time can be
adjusted by using the delay DIP switches to regulate the
outlet air temperature at the end of a heating cycle.
During a call for heat the electronic air cleaner terminal
“EAC”and the humidifier terminal “H” are energized.

Cooling – set the blower speed to give the required
cooling tonnage. Blower starts immediately upon call for
cooling. During a call for cooling the electronic air
cleaner terminal “EAC” is energized. Blower stops
immediately after cooling demand is satisfied.

Continuous fan – By attaching a blower motor speed lead
to the continous terminal “CONT” the blower will run
continuously at that speed until there is a call for heat or
cooling.



VENTING

Failure to follow all instructions can result in flue gas spillage and carbon monoxide
emissions, causing severe personal injury or death. All chimneys must meet the requirements of
NFPA 211 and NFPA 31


Chimney

The furnace must be connected to an adequate chimney or an approved venting system in accordance
with these instructions. An adequate chimney or venting system is one that is sealed and lined with the
capability of producing a -.04" W.C. flue draft and having the capacity to handle the amount of flue
gas that is introduced. A chimney with an internal construction of corrosion resistant tile, stainless
steel, or some other material that will withstand flue gas temperatures up to 1000

0

F is required.

Masonry and metal chimneys shall be constructed in accordance with applicable building code
requirements. Masonry chimneys shall be lined with an approved clay tile liner or a listed chimney
lining system installed in accordance with manufacturers’ instructions and also meeting the
requirements of NFPA-211 Standard for Chimneys, Fireplaces, Vents, and Solid Fuel-Burning
Appliances. Metal chimneys also shall meet the requirements of NFPA-211. Factory built chimneys
shall be listed and shall be installed in accordance with their listing and NFPA-211.

Prior to installation of the furnace, the chimney or venting system shall be examined by the installer
and determined to be in good condition. All joints of the chimney must be tightly sealed. The inside of
the chimney should be free of all obstruction, such as loose brick, broken pieces of tile, or corroded
metal. If chimney flues are divided or there are multiple flues within one chimney, make sure there are
no openings in the partition separating the divided or individual flues. When a new appliance is
connected to an existing chimney, that chimney shall be brought up to current requirements.
Chimneys which are relined shall be done so with an approved liner that will resist corrosion,
softening, or cracking from the flue gasses.
