I PORTANT INFOR ATION! READ FIRST
The heater is designed for use as a construction heater under ANSI Z83.7a-2000. Heater is not
intended for use in pest remediation. The primary purpose of construction heaters is to provide
temporary heating of buildings under construction, alteration, or repair and to provide emer-
gency heat. Properly used, the heater provides safe, economical heating. Products of combustion
are vented outside the area being heated.
The heater IS NOT designed as an Unvented Gas Fired Room Heater under ANSI-Z21.11.2 and
SHOULD NOT be used in the home.
ANSI A119.2(NFPA 501C)-1987 Recreational Vehicle Standard prohibits the installation or stor-
age of LP-gas containers even temporarily inside any recreational vehicle. The standard also pro-
hibits the use of Unvented Heaters in such vehicles.
NFPA-58 1989 STANDARD FOR THE STORAGE AND

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 AY BE UNPLUGGED IN E ERGENCY SITUATIONS ONLY. OTHERWISE,
DO NOT STOP THE UNIT BY UNPLUGGING IT. UNIT NEEDS TO COOL
DOWN USING ITS OWN FAN. FAILURE TO CO PLY WITH PROPER SHUT-
DOWN PROCEDURES CAN CAUSE DA AGE TO THE CO BUSTION
CHA BER, HEAT EXCHANGER, SAFETY FEATURES AND WILL VOID
WARRANTY.

AINTENANCE
Prior to starting any maintenance work be sure to disconnect unit from power supply after
the unit cools down fully and fan shuts off! (Shut Down Procedures page 6)
To ensure the proper function of the unit, it must be serviced on regular basis. Maintenance can
be performed, excluding the control devices and safety limit controls, by an authorized trained &
certified Heat Wagon dealer. The control devices and safety limit controls do not need routine
maintenance. If these items fail they must be replaced.
- Do not use any aggressive cleaning agents, which are harmful or environmentally unfriendly,
when cleaning the unit.
- Do not use water jet when cleaning the unit.
- Pressurized air may be used for maintenance. Be careful not to damage the fan blower wheel
with too much pressure (<30 psi).
- Check whether the unit is free from mechanical damage, replace faulty parts as necessary.
- Check fan blower wheel of the fan at regular intervals and clean it with a small
brush when needed, especially in a dusty (drywall) environment.
- Check functionality of control and safety devices regularly.
- Have the flue gas values of the burner checked regularly by authorized agents.
- Be sure to store the unit in a dust free and dry place when it is not used for a long period of
time. Cover the exhaust flue to prevent entry of foreign objects.
