• The most important safety device on this equipment is a safe operator. It is the operator’s responsibility to read
and understand all of the safety and operating instructions in the manual and to follow them. Most accidents
can be avoided.
• A person must understand the operation of this equipment and be trained in it’s usage before operating the
equipment. An untrained operator exposes himself and others to possible serious injury or death.
• Do not modify the equipment in any way. Unauthorized modication may impair the function and/or safety and
could affect the life of the equipment.

4.2 - General Safety Information
! CAUTION ! - The heater is not recommended for home or recreational vehicle use. The heater
should not be used in aerial bucket truck.
! CAUTION ! - Do not use heater in a space where gasoline or other liquids having ammable
vapors are present.
! CAUTION ! - Heater produces radiant infrared heat which is an open ame. Keep solid com-
bustibles, such as building materials, paper or cardboard, a safe distance away from the heater
as recommended. Never use the heater in spaces which may contain volatile or airborne com-
bustibles, dust particles, paint, thinner, solvents or unknown chemicals.
Safety Precautions:
It is necessary to follow these safety precautions, each time, prior to using the product.
The Safety Precautions are not limited to, but must include the following items;
1. Do not use the heater for anything other than its intended use.
2. This heater is designed to function as a two-stage regulator system. A rst stage regulator is required at the
bottle dropping the pressure down to 10 P.S.I. (pounds per square inch). The regulator built into the unit then drops
the 10 P.S.I. down to 11” WC (water column).
3. Make sure all L.P. ttings are tight. Only a pipe joint compound that is resistant to liquied petroleum gases should be
used.
4. The propane bottle must be vapor draw style, DOT (for U.S.) or CTC (for Canada) approved, 20 or 40 lbs gas cylin
der. Do not use a forklift or liquid withdrawal cylinder. Use only LPG (propane) fuel.
5. Propane gas is very ammable. Propane is scented and its strong odor is readily detectable. If a gas odor is detected
at any time, do not operate or continue to operate the unit until the source of the gas odor has been located. In the
event of a leak, propane is heavier than air and will accumulate in low areas.
. Move the heater outside and ventilate the area. Find and correct the source of the
leak before attempting to light the heater. If the leak cannot be corrected, do not tamper with the heater. Turn the
heater off and consult the manufacturer or a qualied technician.
6. . When lighting with a match, light through the hole provided on the side
of the reector.
7. Do not move, handle or service the unit while hot or burning. Permanent skin tissue damage can occur if contact is
made with the unit. Let the heater cool down after is has been shut off.
8. Never direct this infrared construction heater toward any LP gas cylinder within 20ft. The heater must be a minimum
of six feet from any LP Gas cylinder. Keep away from fabric or combustibles.
distances. Survey the work area for an potential hazards and correct them before operating the heater.
9. Unit should be used in a well ventilated area. When heater is in use, a positive air displacement of at least 4-CFM
per 1,000 BTUH of the heaters rated output should be provided.
10. Heater should be inspected before each use and at least annually by a qualied service agency.

Controls
2. Operation of 1557 Infrared 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 heater orice, fuel inlet, and base for signs of liquid fuel or oil contamination. If present, DO NOT USE
THE HEATER. Have a qualied 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 rst 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 radiant heat from the heater.
d. Turn on the fuel at the LPG cylinder and recheck all ttings 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: First depress and turn the rotary know to the HIGH position. Kneeling behind the heater (DO NOT
STAND OVER THE HEATER) depress and hold the safety shut off valve located under the heater’s ceramic head
in the middle of the base. (Figure 5.2b) While still holding down on the button, push down the igniter button
repeatedly until the heater ignites. Continue holding the safety valve button in for approximately one minute to
heat the thermocouple. When the thermocouple is hot enough, release the safety valve button and the heater will
stay lit. If the heater goes out, turn off the fuel valve and the take valve and wait for ve minutes and repeat the
lighting procedure.
f. ALTERNATE LIGHTING PROCEDURE: A long match may be inserted through the opening in the heater
shield on the left side in lieu of the piezoelectric igniter while observing all other safety precautions. One the heater
has been lit, you can adjust the heat output to the desired setting.
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 ame goes out, turn the rotary knob to the off position.
Let the heater cool down and then disconnect the hose and store away. NOTE: The unit must not be relit for 5
minutes after shut off.
h. In the event the heater is inadvertently tipped over while operating, the gas ow will be cut off by the safety ball
check valve. To reignite, the heater must rst be stood upright. Then to release the safety ball check valve, you
must turn the rotary valve and the cylinder valve to the off position. Then turn the valves on again to reset for igni
tion.
i. Use of the heater in a drafty area may result in a loss of heater efciency. Operate the unit in a draft free area or
turn the back of the heater into the wind.
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, of the hose is cut, it must be replaced prior to heater operation. The replacement hose assembly
must be that specied by the manufacturer.

2. If the heater has not been in service for a long period of time, the following procedure should be initiated before plac-
ing it back into operation. Use an air hose (not to exceed 30 psi) to blow off any dust/dirt that has accumulated on the
heater. Pass the air hose over the entire exposed area of ceramic. (Vacuuming is acceptable)
3. Clean the orice spud allowing the air pressure to ow for approximately one minute. If a residue or deposit inside
the orice spud remains after an attempt has been made to clean it, it must be replaced with a new orice and a
tip-over ball check valve obtained from the factory. DO NOT CLEAN ORIFICE WITH A DRILL OR OTHER METAL
OBJECTS.
