OPERATING INSTRUCTIONS

INSTALLATION

• When transporting, use both lifting eyes located on sides of heater.

• Place the unit on a level and non-combustible surface.

• Minimum clearances from combustible materials for indoor or outdoor installation on
combustible flooring:

- outlet, minimum 10 feet

- sides, minimum 3 feet

- top, minimum 3 feet

- flue pipe exhaust, gas discharge minimum 2 feet

• Manufacturer recommends a free zone of 5 feet around the unit and a minimum distance of 10
feet at the unit’s flue gas openings are to be maintained.

• If the unit is placed indoors, secure an adequate fresh air opening for the burner combustion air.

• The unit may not be installed and operated in premises where explosive or combustible fumes

or dust are present. Check the regulation of local authorities, when necessary.

• Make sure that neither the air inlet nor the air outlet is obstructed.

FUEL SUPPLY

• This heater will burn kerosene (#1 or #2), diesel fuel (#1 or #2), and heating fuel (#1 or #2). It is
highly recommended to use winterized fuel with ambient temperatures less than 20ºF and to
also install optional circulation or fuel tank heaters.

• The installation of this heater must comply with all applicable local codes.

• Check and clean fuel filter (if necessary) on a weekly schedule.

ELECTRICAL

• Electric cable extensions must be connected based on the unit capacity and cable length.

• Connect unit to a power supply with a suitable appliance receptacle (15 Amp).

• Confirm voltage at heater connection (105V min.) to ensure proper operation.

EXHAUST FLUE PIPE

• The unit is to be connected to a flue pipe with adequate draft, to ensure the proper start and
operation of the unit. Refer to page 16.

• The flue pipe is to be made of non-combustible material and clearances from combustible
materials must be a minimum 8 inches (temperature of flue gases is approximately 410º F).

• The flue pipe and its installation must comply with the regulations and instructions given by
the local authorities.

START UP

• Only people who are trained in the operation and supervision of this heater should operate

and maintain the unit.

• Check the unit to make sure that there are no visible defects on the control and safety devices

and that the unit has been installed correctly.

1. Check that the control switch on the control box is in position “0” (STOP).

2. Pre-select desired room temperature on the room thermostat. The temperature must be set
higher than the ambient temperature.

3. Turn the control switch in control box to position “1” (HEATING).

4. When the ambient temperature level is low, the burner switches on automatically. The fan

does not switch on until the set temperature (104ºF) of the heat-exchanger has been

reached (will take approximately 1-5 minutes).

• After starting, the unit runs fully automatically with the pre-selected room temperature
thermostat and it is controlled by its own control devices and safety limit controls.

• The room thermostat (TSTAT) and burner sensor control the running sequences of the
burner and the fan sensor controls the fan function.

• Overheat limit reset (STB) controls and shuts off the heater (burner) in the case of overheating.

• The unit can also be used for ventilation purposes only, if needed.

1. Turn the control switch on the control box to position “2” (VENTILATION).

2. The unit is now in the continuous ventilating mode.

3. Heating is not possible in this mode.

DUCTING (Warm Air)

• Clearness from combustible materials have to be a minimum of 4 inches.

• Use steel ducting or fabric ducting capable of withstanding a minimum temperature of 300ºF.

• Maximum length of duct: 50’ (straight).

• Duct diameter: 12”.

• Make sure that the duct is safely and properly fastened to the outlet.

• Avoid sharp bends and corners to ensure maximum air flow and avoid back pressure/heat

accumulation in heater.

• FAILURE TO COMPLY WITH THESE RECOMMENDATIONS COULD RESULT IN SHUTDOWN

OF THE HEATER.

SHUT DOWN

• Turn control switch to position “0” (STOP).

WARNING!
UNIT MAY BE UNPLUGGED IN EMERGENCY SITUATIONS ONLY. OTHERWISE, DO NOT
STOP THE UNIT BY UNPLUGGING IT. UNIT NEEDS TO COOL DOWN USING ITS OWN
FAN. FAILURE TO COMPLY WITH PROPER SHUT-DOWN PROCEDURES CAN CAUSE
DAMAGE TO THE COMBUSTION CHAMBER, HEAT EXCHANGER, SAFETY FEATURES AND
ALSO VOID WARRANTY.

Important!

The air supply fan continues running
to cool down the combustion
chamber/heat exchanger and then
stops later. The fan can restart for
several times before finally switching off!
