ON-SITE SAFETY PROBLEMS
1) SHORTING OUT OF DEFECTIVE COMPONENTS
This is a very common problem which saves short term expense at the risk of a large future cost.
Any heaters found in this condition should be removed immediately.
2) IMPROPER ENCLOSURES
When heaters are installed partially to the outside for fresh air intake, strict adherence must be
made to the minimum clearance to combustibles given on the instruction plate. Wood framing
around a heater can cause a safety hazard.
3) SUPPLYING LIQUID PROPANE TO HEATER NOT EQUIPPED WITH A BUILT IN VAPORIZER
This problem has occurred upon initial start-up. To minimize the damage, shut off the gas
supply and let the heater run until all of the liquid in the lines had been consumed.
OPERATING INSTRUCTIONS
1) Set the
gas selector valve
for fuel being used. Check for proper gas pressure.
2) Open
manual shut-off valve
on heater.
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.
Bleed air from hose at heater.
5) Set
fan
and
burner switches
to “on” position.
6) Set
thermostat
for desired room temperature.
7) To stop, turn
thermostat
down or turn
fan switch
“off”.
(Burner will turn off; after 5 seconds fan will turn off.)
8) Close
manual shut-off valve
on heater.
NOTE:
If the heater will be shut down over night, close valve at fuel supply first and burn all gas out
of line.
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.
