iii) With Heater Assembly in hand, remove the two (2) mounting brackets and element baffle. Two (2) Phillips screws hold each mounting bracket to the Heater

Assembly and four (4) screws attach the baffle to the element (2 on top and 2 from underneath).

iv) Using screws removed in step iii, attach mounting brackets and baffle to replacement Heater Assembly.

v) Disconnect one of the wire leads from the defective

Heater Assembly (which are still connected to itself and the Remote Control Receiver) and immediately connect it to the new Heater Assembly’s terminal, matching its position. Continue with the remaining wires using the same procedure (refer to Figure 17).

Ensure that exterior intake louvers and firebox cavity are free of dirt/dust.


Normal operation is when the heater emits an odor for a brief period after the heater is initially turned on.

The heater is burning off any dust accumulated during manufacturing or operation.



Trace wiring in unit


Small glowing sections of the element are considered normal.

If larger glowing sections are causing the heater to trip the thermal cutout, unplug unit, discontinue use and replace heater assembly.

Ensure that exterior intake louvers and firebox cavity are free of dirt/dust.


Ensure rod is straight and mounted properly in the bracket, spinning freely away from other components.
