The appliance, when installed, must be electrically grounded in accordance
with local codes or, in the absence of local codes, with the National
Electrical Code, ANSI/NFPA 70 or Canadian Electrical Code, CSA C22.1,
if an external electrical source is utilized. This appliance is equipped
with a three-prong [grounding] plug for your protection against shock
hazard and should be plugged directly into a properly grounded
three-prong receptacle. Do not cut or remove the grounding prong
from this plug. For an ungrounded receptacle, an adapter, which has
two prongs and a wire for grounding, can be purchased, plugged into the
ungrounded receptacle and its wire connected to the receptacle mounting
screw. With this wire completing the ground, the appliance cord plug can
be plugged into the adapter and be electrically grounded.
CAUTION: Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and dangerous operation.
Verify proper operation after servicing.
Note: For testing flame sensor circuit use a micro-amp meter in series
with sensor. Minimum current should be 1 micro-amp during operation.
Be careful as flame sensor is in the 115VAC circuit. If current is below 1
micro-amp, remove sensor, clean with light sandpaper and retest.
Note: This heater is equipped with a remote bulb electronic thermistor
control located down low at the back of the furnace. Sometimes due to
field locations different air currents may effect the control sensing of the

for better room air sensing and control.
Replacement of Thermistor with 24 Volt Wall Thermostat
1. If furnace is installed, turn off gas supply and electric supply.
2. Remove casing front.
3. Remove black hose from front nipple on pressure switch.
4. Remove junction box cover (4 screws).
5. Please refer to wiring diagram for removal of the following
wires.
6. Internal Electronic Thermostat/Temperature Control Board
Attention! No 24 volt wall thermostat wires are to be attached
to the internal electronic thermostat.
7. Control Board
A. Remove white wire form screw marked W.
B. Remove yellow wire from screw marked C.
C. Remove red wire from screw marked R.
8. Route (2) wires from any 24 volt wall thermostat through the
casing back of furnace to the screws marked W and R on the
control board.
9. Replace junction box cover (4 screws).
10. Replace black hose onto front nipple on pressure switch.
11. Replacement of thermistor with 24 volt wall thermostat is
completed.
