OPERATING INSTRUCTIONS
1) Set the
gas selector valve
for fuel being used. The conversion shall be done by the owner or
lessor of the equipment.
NOTE
: When using Propane Gas the Selector Valve
MUST
be locked in the “ON” position.
2) Ensure the
manual shut-off valve
(valve nearest the burner) is in the “ON” position.
3) Connect power supply (115 volt). Check voltmeter to confirm full voltage.
4) Slowly open shut-off valve at gas meter or propane tank. Check for leaks.
5) Push
START
button
6) Set
thermostat
for desired room temperature.
7) To stop turn gas off.
The appliance area should be kept clear and free from combustible materials, gasoline, and other
flammable vapors and liquids.
Ensure that the flow of supply air and combustion gases is not obstructed.
The installation and operation of the heater shall comply with the code requirements specified by
the authorities having jurisdiction.
General criteria for the use of construction heaters may be found in the applicable sections of
American National Standard A-10.10-1987, Safety Requirements for Temporary and Portable Space
Heating Devises and Equipment Used in the construction industry.
THE INSTALLATION AND MAINTENANCE OF THE HEATER MUST BE ACCOMPLISHED BY A
QUALIFIED SERVICE PERSON.
3) INSUFFICIENT VAPORIZATION AT SUPPLY
Normally caused by undersized supply tank.
4) IMPROPER GAS SUPPLY PRESSURE
Usually a result of propane supply pressure being too high because of improper or lack of
regulation or too low of natural gas pressure at meter.
5) DIRTY GAS SUPPLY
Dirty gas can cause strainers to plug or form a build-up in the burner orifice.
6) LACK OF PREVENTIVE MAINTENANCE
Heaters must be cleaned as required, especially when used in a dirty environment.
7) IMPROPER SUPPLY OF FRESH AIR
It is normally recommended that the intake air of the heater be taken from outside the enclosed
area. This provides a slight pressurization and prevents any problems associated with re-
circulation.
