Electronic Air Cleaner
Th
e integrated furnace control has provisions to supply power and
control an electronic air cleaner rated at 120vac, 1.0 amp max. 120
volt power will be available at these terminals whenever the
circulating fan is operating in the heating or cooling modes.
Power Humidifi er
Th
e integrated furnace control has provisions to supply power and
control a line voltage humidifi er or the primary of a 120 / 24 volt
humidifi er step down transformer, rated at 120vac, 1.0 amp max.
NOTICE
All HUM and EAC terminals are 120V. Do not directly
connect 24V equipment to these terminals.
Th
is furnace is equipped with a HSI (Hot Surface Ignition) device.
Each time that the room thermostat calls for heat, the HSI lights the
main burners directly. See the lighting instructions on the furnace.
To Start The Furnace
1.
Remove the burner compartment access door.
2.

WARNING
SHOULD OVERHEATING OCCUR OR THE GAS
BURNERS FAIL TO SHUT OFF, CLOSE THE MANUAL
GAS VALVE FOR THE FURNACE BEFORE SHUTTING
OFF THE ELECTRICAL POWER TO THE FURNACE.
FAILURE TO DO SO CAN CAUSE AN EXPLOSION OR
FIRE RESULTING IN PROPERTY DAMAGE, PERSON-
AL INJURY OR LOSS OF LIFE.
BEFORE RESTARTING THE FURNACE, CHECK ALL
PLASTIC VENTS AND WIRES FOR DAMAGE.
NOTICE
NOTE: On initial startup, the drain trap assembly will be
dry. A dry trap will allow fl ue gases to fl ow through the
recovery coil drain, which will prevent the condensate
from draining from the recovery coil. If enough conden-
sate accumulates in the recovery coil, the recovery coil
pressure switch will sense this condition and break its
electrical contacts, and extinguish combustion. If this takes
place, the induced blower will stop aft er a brief post-purge
cycle, the condensate will drain out and fi ll the trap. If the
thermostat is still calling for heat, the ignition sequence
will start again aft er a 5 minute wait.
