CALIFORNIA RESIDENTS ONLY-WARNING:
This product and the fuels used to operate this product (liquid propane or natural gas), and the
products of combustion of such fuels, can expose you to chemicals including benzene, which is

The heater is designed and approved for use as a construction heater under ANSI Z83.7 CSA2.14.
It is hard to anticipate every use which may be made of this heater. CHECK WITH YOUR LOCAL
FIRE SAFETY AUTHORITY IF YOU HAVE QUESTIONS ABOUT APPLICATIONS.
PROPANE TANK TOP CONSTRUCTION HEATERS
This is a direct-red tank top construction heater for either indoor construction or outdoor use. Its intended
use is primarily the temporary heating of buildings or structures under construction, alteration or repair. All the
products of combustion generated by the heater are forced through the heater and released into the area being
heated. This heater operates at approximately 98%+ combustion efciency but still produces a small amount
of carbon monoxide. Humans can tolerate small amounts of carbon monoxide for short periods. Carbon
monoxide can build up in a heated space and failure to provide adequate ventilation could result in poisoning
or death.
Other standards govern the use of fuel gases and heat producing products in specic applications.
Your local authority can advise you about these.
IMPORTANT: READ THIS USER’S MANUAL CAREFULLYAND COMPLETELY BEFORE TRYING
TO OPERATE OR SERVICE THIS HEATER. IMPROPER USE OF THIS HEATER CAN CAUSE
SERIOUS INJURY OR DEATH FROM FIRE, EXPLOSION AND CARBON MONOXIDE POISONING.

Accidents are always tragic especially because so many of them could have been prevented with little care
and judgment. There are some basic good practices, we hope you will follow for safe use of your heater.
• Children should be carefully supervised, when they are in the area.
• Always maintain proper clearance from combustible materials. Minimum clearance from combustibles.
Side & Rear: 36” (91cm); Top: 36” (91cm); Front: 60” (152cm); Floor: 0” when installed on 20lb cylinder.
Note: Not for use on nished oor.
• Heater must be placed on level and stable surface.
• Never place anything including clothes or other ammable items on the heater.
• The appliance area shall be kept clear and free from combustible materials, gasoline and other
ammable vapours and liquids.
• Do not modify or operate a heater which has been modied.
• Adequate clearance for accessibility and for combustion & ventilation air supply must be maintained
at all times when the heater is operating.
• Service and repair should be done by a qualied service person. The heater should be inspected
before each use and at least annually by a qualied person. More frequent cleaning may be
required as necessary. Do not service while hot or operating.
• Never connect heater to an unregulated gas supply.
• The heater is shipped from the factory for LP(Propane) gas. This heater is for use with
propane gas only, do not convert heater to any other gas. Installation must conform to local
codes or, in the absence of local codes, with the standard for the Storage and Handling of Liqueed
Petroleum Gases ANSI/NFPA 58 and the Natural Gas and Propane Installation Code CSAB149.1.
• The minimum and maximum inlet pressures to the regulator from the gas tank are 17.5 psi and bottle
pressure, respectively. Use only the regulator & hose assembly provided with the heater. Inspect the
regulator/hose assembly prior to each use of the heater. If there is excessive abrasion or wear,
or hose is cut, replace with regulator/hose assembly listed on the parts list prior to using this heater.
• Gas supply connections should be checked using a 50/50 solution of liquid dish soap and never use
a ame to check for gas leaks.
• Do not restrict inlet or outlet by any means. The ow of combustion and ventilation air is not to be obstructed.
• This heater should not be directed toward any propane-gas container within 20 ft (6M). The heater
must be located at least 6 ft. (1.83 m) in the U.S.; or (ii) 10 ft. (3 m) in Canada, from any other
propane gas container.
• The propane cylinder supply system must be arranged to provide for vapour withdrawal from the
operating cylinder.

• A collar to protect the propane gas valve.
• A shutoff valve terminating a Propane gas cylinder valve outlet as specied in the American National
Standard for Compressed Gas Cylinder Valve Outlet and Inlet Connections.
• Asafety relief valve having direct communications with the vapor space of the tank.
• An arrangement of vapor withdrawal.
PROPANE SUPPLY
This heater requires a 20 lb propane cylinder for operation. (Not included).
The propane (LP) gas tank must also be equipped with the following:
REFILLING THE PROPANE GAS TANK
Propane is safe to use when properly handled. Careless handling of the Propane gas tank could result in
re and/or an explosion. Therefore:
• Always keep tank/cylinder securely fastened in an upright position.
• Avoid tipping tank on its side when connected to a regulator since this may cause damage to
diaphragm in regulator.
• Handle valves with care.
• Never connect an unregulated Propane tank to construction heater.
• Do not subject Propane tank to excessive heat.
• Tightly close the gas shutoff valve on the Propane tank after each use.
• The POL tting must be protected when disconnected from the propane tank.
• Never store a Propane gas tank inside a building or in the vicinity of any gas burning appliance.
THE DISCONNECTED TANK MUST NEVER BE STORED IN A BUILDING,
GARAGE OR ANY OTHER ENCLOSED AREA.
ALL NEW CYLINDERS MUST BE PURGED BEFORE THE FIRST FILLING.
• Turn heater gas valve knob and gas tank valve to OFF position.
• Propane tank valve equipped with the old style tting has LEFT HANDED THREADS. Turn POL tting
CLOCKWISE to loosen. Protect POL tting when disconnected from tank.
• Have tank lled by your local Propane gas supplier.
• Some propane tanks have a bleed-off valve. This valve should be inspected for leaks after each lling of
the tank. Turn clockwise to close the valve.
• Fasten full Propane tank and connect POL tting to tank valve by turning COUNTERCLOCKWISE.
• With heater gas valve knob still in the OFF position, turn ON tank valve and check for leaks with soap solution.
The propane (LP) gas pressure regulator and hose assembly of 30K BTU models supplied with
the heater must be used without alteration.
The hose assembly shall be visually inspected prior to each use of the heater. If it is evident that there is
excessive abrasion or wear, or the hose is cut, it must be replaced prior to the heater being put into operation.
The replacement hose assembly shall be that specied by the manufacturer.

Mounting bolt knob should be positioned to the outside of tank collar and be positioned as closely as possible
directly opposite to the cylinder valve outlet. See Figures 1 and 2.
2. (Applies to dual burner models only). Firmly secure to tank by hand-tightening mountingbolt knob.
Do not overtighten mounting bolt knob.
3. Make sure heater regulator knob is in the OFF position.
4. Insert regulator’s connector into tank’s valve outlet tting and turn left (counterclock-wise) until fully tightened.
Threads are left-handed. (Figure 3.)
NOTE: Heater features a hand wheel that can be used to tighten the tting to the cylinder. No
wrench required.
5. Open propane tank valve slowly by turning counterclockwise .
6. Check all ttings for leaks. Apply a 50/50 mixture of liquid soap and water to all joints. Bubbles forming
show a leak. Correct all leaks at once.
7. Always remove propane tank from heater after each use. Do not store heater while attached
to propane tank.
WARNING: NEVER USE AN OPEN FLAME TO CHECK FOR LEAKS.
