 Overheat Switch
When the heater gets too hot during operation (for example when the filters or air outlet louvers are
blocked) this device turns the gas off automatically. Remove cause of overheat (clean filters) allow
heater to cooI, then re-ignite.
 Fuse
The electrical circuits are protected by a fuse. When the fuse blows, the heaters will not operate at all.
The fuse must be replaced by an authorized person.
 Flame Failure Device

INCLUDED IN CARTON:
Customers Operating Information/Manual Gas Valve
IMPORTANT
1. The appliance must be installed in accordance with state and local codes.
2. For information on gas rate, see data plate on the appliance.
3. When using this appliance, ensure that the room is correctly ventilated. Check the local gas
authority for information on ventilation requirements.
4. The heater must not be installed where curtains or other combustible materials could come into
contact with it. In some cases, curtains may need restraining. It must be installed 2" (50mm) away from
walls.
5. This appliance is not designed to be built in.
6. If you move, check the gas type in the area where you are moving to. The local gas authority will be
able to advise on local regulations.
7. This heater discharges a large volume of warm air at low level to provide even heat distribution. If
the air in the room contains cooking vapor or cigarette smoke, and the heater is used on a carpet,
the surface of the carpet may become discolored.
In addition, some nylon carpets contain dyes which may be affected by the warm air flow. Some soft
vinyl surfaces are also subject to distortion, or discoloration by warm air. To prevent discoloration of
carpets etc., a nonflammable board should be placed under the appliance, extending about 30" (750mm)
in front of it.

USAGE AND INSTALLATION INFORMATION

NOTICE BEFORE INSTALLATION
The heater must be installed by a qualified service person according to these installation instructions.
When used without adequate combustion and ventilation heater air the heater may give off carbon
monoxide.
Check your local building codes for the proper method of installation. In the absence of local codes, this
heater installation must conform with American National Standard (National Fuel Gas Code) ANSI
Z223. 1/NFPA54.
Available from the American National Standards lnstitute, Inc.,
1430 Broadway, New York, NY 10018, or from the National Fire
Protection Association, Batterymarch Park, Quincy, MA 02269.
All correspondence should refer to Model No., Serial No., and type of gas.
WARNING: Electrical Grounding Instructions
This appliance is equipped with a three-prong (grounding) plug for your protection against shock hazard
and should be plugged directly into a properly grounded three-prong receptacle.
This appliance may be installed in an aftermarket manufactured (mobile) home when not prohibited by
state or local code. (Aftermarket = completion of sale, not for purpose of resale from manufacturer.)
This heater shall not be installed in a confined space or unusually tight construction unless provisions
are provided for adequate combustion and ventilation air.
The National Fuel Gas Code ANSI Z223. 1/NFPA54 defines a confined space as a space whose volume
is less than 50 cubic feet per 1,000 Btu per hour (4.8m3 per kW) of the aggregate input rating of all
appliances installed in that space and an unconfined space as a space whose volume is not less than 50
cubic feet per 1,000 Btu per hour (4.8m3 per kW) of the aggregate input rating of all appliances installed
in that space.
Rooms communicating directly with the space in which the appliances are installed, through openings
not furnished with doors, are considered a part of the unconfined space.
The folIowing formula can be used to determine the
maximum heater rating per the definition of
unconfined space:
BTU/HR=(L1+L2)Ft × (W)Ft × (H)Ft × 1000
50
Consider two connecting rooms with an open area
between, with the following dimensions:
BTU/HR=(151/2+12) × (12) × (8) × 1000
50
=52800 BTU/HR
If there is a door between the two rooms that can
be closed the calculation must be based only on the
room with the heater.
BTU/HR=(151/2) × (12) × (8) × 1000
50
=29760 BTU/HR
WARNING: If the area in which the heater may be operated is smaller than that defined as an
unconfined space or if the building is of unusually tight construction, provide adequate combustion and
ventilation air by one of the methods described in the National Fuel Gas Code, ANSI Z223.1/NFPA54,
Section 5.3 or applicable local codes.

b) Weather stripping has been added on openable windows and doors, and
c) Caulking or sealants are applied to areas such as joints around window and door frames, between
sole plates and floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing,
electrical, and gas lines, and at other openings.

 TURNING ON
Press the ON/OFF button to operate the heater. The ON
indicator will glow green. After approximately 20 seconds
the spark generator will be heard before the burner
ignites and the ON indicator glows red, indicating that the
burner is lit. Warm air can be felt coming from the
louvers 15 seconds later.
If the heater does not ignite on initial try, air may be remaining in the gas supply line.
The spark generator will only continue for 30 seconds. After this, it will be necessary to press the
ON/OFF button OFF, then ON again.
 TURNING OFF
Simply press the ON/OFF button to switch off the heater. The
ON indicator will go out. The convection fan will continue to
operate for several minutes after the burner has gone out in
order to cool the appliance. Do not unplug the appliance
while the convection fan is running.
DO NOT turn heater off by unplugging.
The convection fan will continue to run until the appliance cools.
 ROOM TEMPERATURE ADJUSTMENT
The room temperature and pre-set temperatures can only be displayed and adjusted when the
heater is running.
Press the " " button to increase the temperature setting
or " " button to decrease the temperature setting.
The temperatures can be preset to:
a) [L] low (about 50°F)
b) [60°F] to [80°F] in 2°F increments
c) [H] (continuously high)
If the heater does not ignite then the pre-set temperature may not be set to a setting which is
higher than the actual room temperature.
 AUTO-OFF FUNCTION
When you select AUTO-OFF, the indicator light will glow.
You have selected a Full Thermostat Control Function.
The heater will cycle High, Low and OFF to maintain the
selected room temperatures.
When the AUTO-OFF indicator is not glowing, you have

 OFF TIMER OPERATION
This feature is useful on cold nights when the unit continues to operate after you have gone to
bed.
The OFF Timer can be selected when the heater is operating manually, in OFF, or in ON Timer mode.
When the OFF Timer feature is selected, the heater will automatically switch off after 60 minutes.
1 Press the OFF Timer button. The OFF Timer indicator
lights up.
The heater will operate at the preset temperature selected in the system memory.
The temperature will automatically run at 80°F if the set temperature is "H".
If selected while the ON Timer is set, the heater will come on and run for 60 minutes, after which it will remain in
ON Timer standby mode.
If the ON Timer is selected after the OFF Timer has been selected, the unit will run for 60 minutes (OFF Timer
mode) and then remain in the ON Timer standby mode.
In all cases where the ON and OFF Timers are selected together, the OFF Timer will take precedence and run
the heater for 60 minutes after which the heater will remain in the ON Timer standby mode.
OFF TIMER STOPS AFTER 1 HOUR.
Five minutes before the finish of the OFF Timer, the OFF Timer indicator will flash, indicating that the function is
nearing completion.
The OFF Timer indicator will then go out at completion of the 60 minute time delay.
In cases where both the ON and OFF Timers are selected, once the OFF Timer has run the heater for 60
minutes, the ON Timer indicator will remain lit and the heater will be in ON Timer standby mode.
To cancel the OFF Timer, press either the ON-OFF button or the OFF Timer button at any time.
 ON TIMER OPERATION
The ON Timer allows you to program the heater to turn on after a pre-determined time period.
As an example, if the time now is10:30 pm and you wish the heater to start at 6:00 am tomorrow morning, then
the ON Timer must be set to 7.5 (hours)
The ON Timer preset times are from 30 minutes to 24 hours.
These times can be selected in 30 minute increments up to 10 hours and then 1 hour increments up to the
maximum of 24 hours.
BEFORE SELECTING THE ON TIMER CONFIRM:
That the desired preset room temperature has been set (see page 12)
