5.0 Special Precautions: ( CAUTION )

5.01 This heater is designed to function as a two-stage regulator system.

Meaning a first stage regulator is required at the bottle. Dropping bottle

pressure down to 10 P.S.I. (pounds per square inch). The regulator built

into the unit drops the 10 P.S.I down to 11” WC (water column).

3 Rev.#7 11-01-06

5.02 Make sure all L.P. fittings are tight. Use only a pipe joint compound that is

resistant to liquefied petroleum gases.

5.03 Propane bottle must be the vapor draw style, DOT (for U.S.) or CTC (for Canada)

approved 20 or 40 Lb. Gas cylinder. Do not use a forklift or liquid withdrawal

cylinder. Use only LPG (propane) fuel.

5.04 Propane is very flammable. 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 heaver than air and will accumulate in low

areas. Never strike a match, create a spark or flame when you smell gas.

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 manufacture or

qualified technician.

5.05 Do not lean over heater when lighting. When lighting with a match, light through

the hole provided on the side of the reflector. Do not light at orifice.

5.06 Do not move, handle or service unit while hot or burning. Permanent skin tissue

damage can occur if contact is made with the unit. Let the heater cool down after it

has been shut off.

5.07 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 other combustibles. Survey the work area for any

potential hazards and correct them before operation.

5.07 Unit should be used in a well-ventilated area. Provide a positive air displacement

of at least 4-CFM per 1000 BTUH of the heaters rated input.

5.08 Heater should be inspected before each use and at least annually by a

Qualified service agency.

5.09 Minimum ambient temperature for using this heater is -20°F –(29°C). The heater

Is designer for use as a construction heater under ANSI Z83.7 & CGA 2.14.

Check with your local fire safety authority if you have questions about applications.

5.10 WARNING: For the safe installation of this unit, the following table of clearances

Must be maintained.

NOTE: Clearances are established by A.N.S.I. and the Canadian Gas Association

as proper clearances to combustible such as wood, cardboard, tent fabrics etc. in

case of tip over or inadvertent unsupervised operation.

4 Rev.#7 11-01-06

Clearance to Combustibles:

Side: 18”

Rear: 18”

Ceiling: 48”

Discharge End: 48”

(FRONT)

6.0 Operating Procedures:

6.01 Inspect heater orifice, Fuel inlet and base for signs of liquid fuel or oil

contamination. If present, DO NOT USE HEATER. Have a qualified technician

disassemble LPG supply line and components to remove liquid fuel or oil before

use.

6.02 Place heater on secure level surface. Heater must be positioned such that it is not

directly exposed to wind, water, spray, rain and/or dripping water.

6.03 Connect LPG supply hose with first stage regulator assembly to a 20 or 40 LB.

approved cylinder. (First stage regulator should take bottle pressure down to

10 to 35 PSI.) Connect to heater by either a quick disconnect fitting or 9/16”

Left Hand threaded fitting. Tighten all connections.

Locate LPG gas cylinder at least 6Ft. from heater, in a position away from the

Direct path of radiant heat from the heater.

6.04 Turn on the fuel at 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.

6.05 TO IGNITE: First depress and turn rotary knob, located on the back of heater

base, too the HIGH position, first detent. Kneeling behind heater (DO NOT

STAND OVER HEATER) Second, depress and hold the brass button on the safety

shut off valve located under the heaters ceramic head in the middle of the base.

While still holding down on the brass button, push down on 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 tank valve and wait for five minutes and

repeat lighting procedure.

6.06 Alternate lighting procedures: 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. Once the heater has been lit, you can adjust the heat

output to the desired setting.

6.07 To turn heater off: First turn off the fuel supply at the bottle. This burns off excess

fuel in the supply hose and lowers line pressure. When the heater flame goes out,

turn the rotary knob to the off position. Let the heater cool down and you can

5 Rev.#7 11-01-06

disconnect hoses and store away. NOTE: The unit must not be relit for 5-minutes

after a shut off. Follow paragraph 6.05 to reignite.

6.08 In the event heater is inadvertently tipped over while operating, the gas flow will be

cut off by the safety ball check valve. To reignite you must first stand heater

upright. Then to release the safety ball check valve, you must turn off the rotary

valve on the back of the heater and fuel cylinder, wait 5-minutes, then turn valves

on again to reset for ignition. If heater still will not ignite, see Restart Trouble

Shooting (see Dwg. #109207) for further instructions.

6.09 Use of the heater in a drafty area may result in a loss of heater efficiency.

Operate the unit in a draft free area or turn the back of the heater into the wind.

6.10 NOTE: The hose assembly shell be visually inspected prior to each use. If it is

evident that there is excessive abrasion 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 manufacture. See parts list.

6.11 When a heater is installed or stored indoors you must conform to the local building

Codes, or in there absence the current Standard for Canada or the U.S.,

CAN/CGA-B149.2 or ANSI/NFPA-58 titled Storage and handling of liquefied

petroleum gases. When stored or not in use the connection between the LPG

cylinder/bottle and the heater must be disconnected and the cylinder removed from

the heater.

7.0Care, Maintenance & Service:

7.01 Visually inspect daily for oil or liquid fuel contaminant present in the heater or fuel

supply hose. If any is evident, heater should be cleaned and or repaired by a

qualified technician before use.

7.02 If the heater has not been in service for a period of time, the following procedure

should be initiated before placing it back into operation. Use an air hose (not to

exceed 30 PSI.) Blow off any dust/dirt that has accumulated on the heater. Pass

then air hose over the entire exposed area of ceramic. Vacuuming is acceptable.

7.03 Clean the venture tube and orifice spud allowing air pressure to flow for

approximately one minute. If venture still appears dirty, remove orifice bracket and

clean with a nylon brush (toothpick, pipe cleaner) If a residue or deposit inside the

orifice spud remains after an attempt has been made to clean it, it must be

replaced with a new orifice and a tip-over ball check obtained from the factory.

DO NOT CLEAN ORIFICE WITH A DRILL OR OTHER METAL OBJECTS.

7.04 Wipe the reflector clean using a soap and water solution or a non-abrasive

aluminum cleaner.
