enclosure as this will cause heater to overheat and could
create a hazard.
10. When mounting heater, use care when drilling mounting
holes and mounting heater to building structure to avoid
damaging internal heater components. Be sure to loosen
mounting screws ½ turn to allow for expansion and contraction.
11. Do not remove or bypass the safety limit control(s) (thermal
protectors) as this could allow heater to become a fire hazard, see heater wiring diagram supplied with heater.
12. The factory installed wires inside wireway are used to connect the built-in controls. Limit the maximum current to no
more than 45 total amp. Refer to instructions and current
capacity rating as provided with the accessory.
13. Heaters that are not installed end to end must have end
caps installed to cover exposed ends of heater.
14. Do not allow objects to be placed on top of heater as they
may be damaged or create a fire hazard.
15. To avoid damaging heater, do not use a screw driver to
separate front cover from back housing. Use only a putty

OPERATION INSTRUCTIONS
1. After heater(s) are completely assembled and installed, set
thermostat or operating controls for NO HEAT and energize
the heater circuit (s). Verify the heater(s) are not producing
heat.
2. Adjust thermostat or operating control to call for heat. Allow
heater(s) to operate for a few minutes and verify all heaters
are producing heat.
Note:
during initial start up, heaters may exhibit a new smell
and possibly some slight smoke from the manufacturing
residues on the heating element. Allow heaters to operate for
approximately 30 minutes to dissipate these residues.
Ventilating the area may be desired.
3. To set thermostat or operating controls to maintain desired
comfort level, allow heaters to operate until room ambient
temperature reaches the desired level. The thermostat or
operating control can then be adjusted to maintain this temperature.
Note:
when built-in thermostat and/or disconnect switch is/or
provided, access to these controls will be through grille openings
at either end of the heater. To rotate the thermostat shaft will
require a small flat blade screw driver. The disconnect switch is
a rocker switch that can be operated with the same screw driver
or tool through the openings.
4. If built-in thermostat is provided, after room reaches desired
comfort level, rotate thermostat shaft counterclockwise until
the thermostat clicks. This should allow the thermostat to
cycle the heater on and off to maintain this temperature.
Rotation in the clockwise direction will allow the heater to
remain ON MORE and will maintain a HIGHER room ambient. Likewise, rotation in the counterclockwise direction will
result in the heater remaining ON LESS and the room ambient will be LOWER. If remote thermostat or other types of
controls are provided, refer to the instructions provided with
these controls for proper operation.
IMPORTANT NOTE:
safety limit (Thermal Protector– see Fig. 8) to automatically turn
off the heater if it is blocked or otherwise overheats due to an
abnormal condition. The heaters should not be cycling off on
this safety control during normal use. If this is occurring, check
heater installation to assure it has adequate clearances and the
free airflow around heater is not restricted. If heater continues
to cycle on this safety control, discontinue using until it can be
inspected and/or repaired by a qualified electrician.
These heaters are provided with a built-in
MAINTENANCE INSTRUCTIONS
Your heater will give your years of service and comfort with only
minimal care. The user can perform periodic cleaning of the
exterior cabinet, but all other interior cleaning and servicing
should be done by a qualified service person.
