2. Operation of 1590 Construction Heater:
Choose a location where installation will provide suitable proximity to the work area yet minimize obstructions during use
and in the event a rescue is necessary. Once a location is chosen:
a.
Inspect the control box fuel lines, fuel inlet, and base for signs of liquid fuel or oil contamination. If present, DO
NOT USE THE HEATER. Have a qualified technician disassemble the LPG supply line and components to
remove the liquid fuel or oil before use of the heater.
b.
Place the heater on a secure and level surface. The heater must be positioned such that it is not directly exposed
to wind, water, spray, rain, and/or dripping water.
c.
Connect the LPG supply hose with the first stage regulator assembly to a 20 or 40 lb approved cylinder. (First
stage regulator should take bottle pressure down to 10 - 35 psi). Connect the hose to the heater and tighten all
connections. Locate the LPG gas cylinder as least 6 ft away from the heater in a position away from the direct
path of heated flow from the blower.
d.
Turn on the fuel at the LPG cylinder and recheck all fittings for possible leaks using a soap solution. Tighten any
leaks found and retest. Never use a match to check for leaks. NOTE: The longer the fuel hose length, the longer
period of time to purge the hose of air from the initial hookup.
e.
IGNITION:
(DO NOT STAND OVER THE HEATER OR LEAN OVER THE CHIMNEY) Turn heater control switch
to the “on” position. There will be a 4 second delay prior to ignition once the switch has been turned on, to facili-
tate a safety purge of the combustion chamber. After this delay the pilot should be lit, and the heater should fire.
f.
Connect a Pelsue heat-resistant blower hose to the heater outlet, in order to direct fresh, heated air to desired
location. Ensure that NO toxic fumes are blown into an unventilated area.
g.
TO TURN HEATER OFF:
First turn off the fuel supply at the LPG bottle. This burns off any excess fuel in the
supply hose and lowers the line pressure. When the heater flame goes out (lack of combustion noise will be evi-
dent) turn the control switch to “off”. Leave the heater / blower plugged in to an electrical receptacle, so the blower
continues to run for at least 5 minutes, to cool the heat exchanger. Disconnect the hose from the propane bottle
to the heater. Check for leakage. Once cool, disconnect power and remove the blower hose.
j.
NOTE: The hose assembly shall be visually inspected prior to each use. If it is evident that there is excessive abra-
sion or wear, or the hose is cut, it must be replaced prior to heater operation. The replacement hose assembly
must be that specified by the manufacturer.
