B - Low Heat Switch
The Low Heat Switch supplies power to the heater fan and
the heater element. When the switch is in the ON position
(“ I ”) the heater operates on LOW.
C - High Heat Switch
The High Heat Switch supplies power to the heater fan and
the heater element. When the switch is in the ON position
(“ II ”) the heater operates on HIGH. The Low Heat Switch
must also be in the ON position (“ I ”) for the high heat
setting to operate.
Resetting the Temperature Cutoff Switch
Should the heater overheat, an automatic cut out will turn
the replace off and it will not come back on without being
reset. It can be reset by switching the On/Off Switch to Off
and waiting ve (5) minutes before switching the unit back
on.
!NOTE: If operating the unit with a remote control, the
remote may require re-initializing after turning the power
off.
CAUTION: If you need to continuously reset the heater,
disconnect power and call Dimplex customer service at
1-888-DIMPLEX (1-888-346-7539).
Remote Control (Figure 2)
The replace is supplied with an integrated On/Off remote
control, that is factory synchronized with the rebox.
To operate, push the ON button to turn replace on, push
the OFF button to turn the replace off. The amount of heat
produced will be dependant on positioning of manual heat
controls.
!NOTE: Ensure that the replace’s On/Off switch is set to
the remote control setting (“ II ” position).
!NOTE: Before attempting any operation with the
remote control, pull the plastic insulator strip out from
between the remote casing and battery cover (Figure 2).
Initialization/Reprogramming
Follow these steps for remote control initialization, if
required:
Set the 3-Position Switch to OFF.1.
Wait a minimum of ve (5) seconds and set the 3 2.
Position Switch to the Remote position (refer to
Operation Section).
Within3. 10 seconds of re-acquiring power, press the ON
button located on the remote control.
!NOTE: You will have only 10 seconds to perform this
last step. Failure to do so will result in these steps
needing to be followed again.
This will synchronize the remote control and receiver.
Battery Replacement
Slide battery cover open on the remote control1. (Figure
3).
Correctly install one (1) 12 Volt (A23) battery in the2.
battery holder.
OPERATION
Manual Controls for Units without Remote
A - On/Off Switch
The power switch controls the electricity supply to the
heater, ame effect and pilot light. When the switch is in
the “ I” position the unit is ON and when the switch is in the
“ O “ position the unit is OFF.
!NOTE: When the pilot light is lit but ames are not
present, power is still supplied to unit and ame effect
light bulb should be replaced.
B - Low Heat Switch
The Low Heat Switch supplies power to the heater fan and
the heater element. When the switch is in the ON position
(“ I ”) the heater operates on LOW.
C - High Heat Switch
The High Heat Switch supplies power to the heater fan and
the heater element. When the switch is in the ON position
(“ II “) the heater operates on HIGH. The Low Heat Switch
must also be in the ON position (“ I“) for the high heat
setting to operate.
Manual Controls for Units with Remote
A - 3-Position Switch
The power switch has two (2) On positions marked with “ I
” and “ II ”. The “ I” position is for manual operation. In this
position the remote control is bypassed.
The “ II ” position is for operating the unit with the provided
remote control. When in “ II ” position the unit is operated
with the ON and OFF buttons of the remote control.
When the switch is in the center (“ O”) position the unit is
off.
