START UP
• Only people 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 remote thermostat. The temperature must be set
higher than the ambient temperature.
3. Open all possible shut-off devices of the fuel supply lines.
4. Turn the control switch on the control box to position “1” (HEATING).
5. 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 startup, the heater is operated automatically by the room thermostat and governed by all
control devices, including the safety limit controls.
• The room thermostat and burner sensor control the running sequences of the
burner and the fan sensor controls the fan function.
• Overheat limit reset 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.
SHUT DOWN
• Turn control switch to position “0” (STOP).
• If moving the heater, close fuel supply followed by turning control switch to position “0” (Stop).
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!
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 WILL VOID
WARRANTY.
