HEATER START-UP
On start-up of the heater, you may experience some odors relating to the first time operation of the heating
components. There also may be an odor associated with dust accumulation in the system if the heater is shut
down for an extended period of time. Allowing the heater to charge to its highest heat storage level (full core
charge) will help expel these odors in a timely manner.
Since room air passes directly through the hot brick core of the heater, air borne particles and odors may be
drawn into the heating system and oxidized. During the oxidation process, odors can be amplified; thus, it is
recommended not to operate the heating system if odors such as that from paints, varnishes, or chemicals are
present in the air. Allow the area to be completely aired out before operating the heater.
ADJUSTING THE ROOM TEMPERATURE SET POINT
Room temperature set point is adjusted differently if using manual charge control versus automatic charge
control. Thus, when making adjustments to the room temperature set point or the brick core charge level, you
must determine whether your heating system is set for automatic or manual charge control.
Automatic charge control - The right indicator light on the control panel will be illuminated. With automatic
charge control, a sensor regulates the amount of heat stored in the heater's brick
core automatically in relation to outdoor temperature.
Manual charge control - The right indicator light will not be illuminated. With manual charge control, the
user regulates the amount of heat stored in the heater's brick core in relation to
outdoor temperature.
How to Adjust Room Temperature Set Point if Using Automatic Charge Control
Step 1 Press the

arrow button to increase the set point or the

arrow button to decrease the set point.
The face plate will automatically return to displaying current room temperature a few seconds after
making an adjustment.
How to Adjust Room Temperature Set Point if Using Manual Charge Control
Step 1 Press and hold the M button until a green bar appears on the MODE digit of the control panel face
plate to indicate room setting can be adjusted. The room temperature set point will appear on the
TEMPERATURE digits of the face plate.
Step 2 Press the

arrow button or the

arrow button to adjust the room temperature set point. The face
plate will automatically return to displaying current room temperature after making an adjustment.
ADJUSTING THE BRICK CORE CHARGE LEVEL
The room heating unit's brick core charge level can be regulated either manually or automatically. The method of
control will be set at the time of installation. If the right indicator light is illuminated on the face plate, the
heater is set for automatic charge control. If it is not illuminated, the heater is set for manual charge control. The
room heating unit will come factory preset for automatic charge control.
Automatic Charge Control
If the room heating unit is set for automatic charge control, the brick core charge level will be regulated automati-
cally in relation to outdoor temperature. An outdoor sensor is required for this method of charge control.
