OPERATION

Continued

  CAUTION:  Label  all  wires 

prior  to  disconnection  when 

servicing controls. Wiring errors 

can cause improper and danger

-

ous operation.

 CAUTION: Do not plug power 

cord  into  electrical  outlet  until 

installation is complete.

Extension Cord

Use extension cord if needed. The cord must 
have  a  three-prong,  grounding  plug  and  a 
three-hole  receptacle.  Make  sure  cord  is  in 
good shape. It must be heavy enough to carry 
the current needed. An undersized cord will 
cause a drop in line voltage. This will result in 
loss of power and overheating. Use a No. 16 
AWG cord for lengths less than 50 feet.

 CAUTION: Verify proper op

-

eration after servicing.

Operating Blower

The  blower  is  connected  to  a  thermostat. 
When unit heats up, the blower will operate. 
A few minutes after unit cycles off or is turned 
off, blower will shut off. Blower will cycle on 
and  off  in  this  manner. 

Note:  If  you  have  a 

heater  with  a  thermostat,  the  heater  and 
blower will not turn off and on at exactly the 
same time. Blower cycle times will vary with 
heat setting selected.

THERMOSTAT CONTROL 

OPERATION

The  thermostatic  control  used  on  these 
models  differs  from  standard  thermostats. 
Standard thermostats simply turn on and off 
the burner. The thermostat used on this heater 
senses  the  room  temperature. At  times  the 
room may exceed the set temperature. If so, 
the burner will shut off. The burner will cycle 
back on when room temperature drops below 
the set temperature. The control knob can be 
set to any comfort level between 1 and 5. All 
plaques will turn off and on.

Note:  The  thermostat  sensing  bulb  mea-
sures the temperature of air near the heater 
cabinet.  This  may  not  always  agree  with 
room  temperature  (depending  on  housing 
construction, installation location, room size, 
open air temperatures, etc.) Frequent use of 
your heater will let you determine your own 
comfort levels.

MANUAL LIGHTING

BLOWER 

OPERATION

  WARNING:  Blower  acces-

sory must be grounded. Blower 

comes  with  a  three-prong, 

grounding  plug  as  shown  in 

Figure  24.  The  plug  is  your 

protection  against  electrical 

shock. Plug it into a standard, 

three-hole, grounded, outlet. If 

cord needs replacing, use only a 

cord with a three-prong, ground

-

ing plug.
