Operating Information
Turning the heater ON
When you press the ON/OFF button, the LED display
will illuminate, the combustion fan will begin to run,
and the spark will ignite the main burner.
This heater has an automatic ignition system. When
the main burner has lit, the combustion lamp will glow
red, and the spark will stop.
If ignition does not occur after 15 seconds, the
appliance will automatically turn off and a fault code
will be displayed on the control panel. This may
occur when using the appliance for the first time or if it
has not been used for a while. Try operating the
appliance again.
There may be a smell of burning dust or oil the first
time the heater is lit or when the heater has been out
of operation for a long time.
The appliance may make noises after ignition or when
it is turned off. This is normal and is due to the
thermal expansion or contraction of its components.
Adjusting the Temperature
The temperature setting and the room temperature
are indicated by the L.E.D. display on the control
panel. When the appliance is turned on the
temperature setting will be displayed for 10 seconds.
The display will then show the room temperature.
The default temperature setting is 72°F.
To change the temperature setting press one of the
temperature control buttons once. The “Set Temp”
should light up and the display will show the current
temperature setting. Continue to press the control
buttons until the desired temperature setting is
reached. After 10 seconds the display will return to
showing the room temperature.
The thermostat automatically modulates the burner
and the fan to maintain the temperature setting.
The temperature settings available are:
LO - burner is on minimum combustion
60°F - 80°F in two degree increments
HI - burner is on maximum combustion
Turning the heater OFF
Press the ON/OFF button. Do not
turn off by unplugging at the power
outlet.
The fan will continue to run for a short time to prevent
the internal components from overheating.
Economy Mode
Pressing the Economy button will cause the
appliance to go into Economy Mode and the
green lamp will glow. This results in the
temperature setting being reduced by 2°F,
30 minutes after the room temperature has
reached the temperature setting. After
another 30 minutes the temperature setting
is reduced another 2°F. This could result in
the temperature setting being reduced by a
maximum of 4°F. The intent of this mode is to save
energy.

Adjusting Air Flow Direction
The vertical louvers may be adjusted to move the air
flow more to the right or to the left.
Use a screw driver or similar object to bend each
louver to the desired position.
Do not bend repeatedly (no more than 5 times) or
else the louver will break.
The horizontal louver (which determines the vertical
air flow direction) is fixed and cannot be adjusted.
CAUTION
Do not adjust the air flow
louvers while warm air is
flowing.
Sensible Temperature Control
The sensible temperature control feature allows
comfortable heating which matches the conditions in
the room.
Based on the information collected by the room
temperature thermistor when the heating starts, the
heating capacity is automatically adjusted to achieve
a comfortable heating effect and to reach the
temperature setting quickly.
Adding Water to the Humidifier
Warm air is humidified when it passes over the water
in the tray.
To fill the tray, remove the bottom trim panel below
the louvers by pulling on both sides. Pull the tray out
and fill with water. Push the tray back in and attach
the bottom trim panel. Do not operate the appliance
unless the humidifier tray is installed.
During operation a small amount of condensation is
produced in the flue system and drains into the
humidifier tray.
CAUTION
Do not remove the bottom
trim panel or the humidifier
tray while warm air is
flowing.

Care and Maintenance
Filters
Dirty filters reduce the air flow and the appliance’s
ability to produce heat. The filters should be cleaned
frequently during the heating season. If the filters
become blocked the filter indicator lamp will flash red.
Eventually the appliance will turn off and display fault
code 14 on the control panel display.
To clean the filters, the
appliance should be OFF
and cool. Remove the
filter and clean it using a
soft dry cloth or vacuum.
If the filter is greasy wash
with warm soapy water,
rinse, and dry
completely.
Maintenance
Repairs should be performed by a qualified service
technician. The appliance should be inspected
annually by a qualified service technician. More
frequent cleaning may be required due to excessive
lint from carpeting, bedding material, etc. It is
imperative that control compartments, burners, and
circulating air passage ways of the appliance be kept
clean.
Any screen or guard removed for servicing the
appliance must be replaced prior to operating the
appliance. Clean as follows:
1. Turn heat off. Allow to cool for one hour.
2. Remove the front panel by removing six screws.
3. Use pressurized air to remove dust from the main
burner, heat exchanger, and fan blades.
4. Use soft dry cloth to wipe cabinet.
Do not use wet cloth or spray cleaners on the burner.
The flue should be inspected annually for blockages
or damage.
Motors are permanently lubricated and do not need
periodic lubrication. Keep fan and motor free of dust
and dirt by cleaning annually.
Verify proper operation after servicing.
Visual Inspection
of Flame
Check that the burner flames are operating normally.
The flame can be seen through the circular window
through the louvers.
When operating normally the burner flame should
appear as long, clear, blue, stable, streaks. Yellow
flames or an orange color is abnormal and
maintenance is required.
NORMAL
ABNORMAL
Care of Exterior
Dampen soft cloth with warm water. Wring water out
well and wipe the unit.
Do not use volatile substances such as benzene or
thinners. They cause fading of the paint and
deformation of the resin.
Snow Accumulation
Keep the area around flue terminal free of snow and
ice. The appliance will not function properly if the
intake air or exhaust is impeded by obstructions.

Before Making a Service Call
Before making a service call please check the following:
■ At Ignition:
Heater does not operate.
Warm air does not flow when the burner
lights.
Smoke or strange smells are produced
on the first trial light up after installation.
Sharp clicking noises at ignition, or when
unit cuts down on the thermostat, or goes
out.
■ During Combustion:
Clunking noise when the thermostat
operates.
Unit is not heating room.
Air filter is blocked or the louvers are
blocked or obstructed.
Heater will not re-ignite after overheating.
■ When the unit is turned off.
Convection fan continues to run after
turning OFF.
■ Other Points:
Steam is discharged from the flue terminal.
Unit cuts off without apparent reason.
Power Failure.
Is the heater plugged in?
Have the fuses or breaker blown at the fuse box / breaker panel?
Is there a power failure?
Is the air filter blocked?
Is anything blocking the outlet for the hot air?
Is the flue blocked?
The fan is started automatically after a short delay.
This is to allow the heat exchanger to warm up, helping to avoid cold draughts.
This is caused by grease or oil and dust on the heat exchanger and will stop
after a short time.
This is simply expansion noise from the heat exchanger.
This is the sound of the solenoid gas valves opening and closing.
Is the air filter blocked?
Is the set temperature high enough?
Is the warm air outlet blocked by anything?
Are the doors and windows of the room closed?
Was the appliance correctly sized for the space?
Allow heater to cool, clean air filter, operate again.
Even after unit has cooled down, the heater does not ignite again. Repair is
necessary.
Contact a qualified / authorized service provider.
This is to remove the residual heat from the heat exchanger. The fan will stop
when the heater cools down.
High efficiency appliances tend to discharge water vapor on cold days. This
is normal.
Check whether filters are blocked. Dirty filters will cause the heater to overheat.
Switch OFF, then ON again when power is restored to re-set controls.
