WARNINGS
WARNING: FIRE, BURN, INHALATION, AND EXPLOSION
WARNING ICON G 001
HAZARD. KEEP SOLID COMBUSTIBLES, SUCH AS BUILDING
MATERIALS, PAPER OR CARDBOARD, A SAFE DISTANCE
AWAY FROM THE HEATER AS RECOMMENDED BY THE
INSTRUCTIONS. NEVER USE THE HEATER IN SPACES
WHICH DO OR MAY CONTAIN VOLATILE OR AIRBORNE
COMBUSTIBLES, OR PRODUCTS SUCH AS GASOLINE, SOLVENTS, PAINT THINNER, DUST PARTICLES OR UNKNOWN
CHEMICALS.
WARNING
NOT FOR HOME OR RECREATIONAL VEHICLE USE.
The heater is designed for use as a construction heater in accordance with ANSI
Z83.7•CGA2.14. Other standards govern the use of fuel gases and heating products
for specific uses. Your local authority can advise you about these. The primary
purpose of construction heaters is to provide temporary heating of buildings under
construction, alteration or repair. Properly used, the heater provides safe economical heating. Products of combustion are vented into the area being heated.
We cannot foresee every use which may be made of our heaters. Check with your
local fire safety authority if you have questions about heater use.
Other standards govern the use of fuel gases and heat producing products for
specific uses. Your local authorities can advise you about these.
Carbon Monoxide Poisoning: Some people are more affected by carbon
monoxide than others. Early signs of carbon monoxide poisoning resemble the flu,
with headaches, dizziness, and/or nausea. If you have these signs, the heater may
not be working properly. Get fresh air at once! Check for proper ventilation and
have heater serviced.

WARNINGS
Propane Gas: Propane gas is odorless. An odor-making agent is added to propane
gas. The odor helps you detect a propane gas leak. However, the odor added to
propane gas may fade. Propane gas may be present even though no odor exists.
Make certain you read and understand all warnings. Keep this manual for reference.
It is your guide to safe and proper operation of this heater.
• Install and use heater with care. Follow all local ordinances and codes. In the
absence of local ordinances and codes, refer to the Standard for Storage and
Handling of Liquefied Petroleum Gas, ANSI/NFPA 58 and the Natural Gas
Installation Code, CAN/CGA B149.2. This instructs on the safe storage and
handling of propane gases.
• Use only the electrical voltage and frequency specified on model plate.
• The electrical connections and grounding of the heater shall follow the Na-
tional Electric Code, ANSI/NFPA 70 or Canadian Electric Code, Part 1.
• Electrical grounding instructions — This appliance is equipped with a threeprong (grounding) plug for your protection against shock hazard and should
be plugged directly into a properly grounded three-prong receptacle.
• Use only a three-prong, grounded extension cord.
• Use only the hose and factory preset regulator provided with the heater.
• Use only propane gas set up for vapor withdrawal.
• Provide adequate ventilation. Before using heater, provide at least a four and one
half (4.5)-square-foot opening of fresh, outside air for each 100,000 Btu/Hr of
rating. This heater produces carbon monoxide, which is listed by the State of
California as a reproductive toxin under Proposition 65.
• For indoor use only. Do not use heater outdoors.
• Do not use heater in occupied dwellings or in living or sleeping quarters.
• Do not use heater below ground level. Propane gas is heavier than air. If a leak
occurs, propane gas will sink to the lowest possible level.
• Keep appliance area clear and free from combustible materials, gasoline, paint
thinner, and other flammable vapors and liquids. Do not use heater in areas
with high dust content.
• Minimum heater clearances from combustibles:
Outlet: 8 Ft. Sides: 2 Ft. Top: 6 Ft. Rear: 2 Ft.
• Keep heater at least six feet from propane tank(s). Do not point heater at
propane tank(s) within 20 feet.
• Keep propane tank(s) below 100° F.
• Check heater for damage before each use. Do not use a damaged heater.
• Check hose before each use of heater. If highly worn or cut, replace before
using heater.
• Locate heater on stable and level surface if heater is hot or operating.
• Not intended for use on finished floors.
• Never block air inlet (rear) or air outlet (front) of heater.
• Keep heater away from strong drafts, water spray, rain, or dripping water.
• Do not leave heater unattended.
• Keep children and animals away from heater.
• Never move, handle, or service a hot, operating, or plugged-in heater. Severe
burns may result. Wait 20 minutes after turning heater off.
• To prevent injury, wear gloves when handling heater.
• Never attach duct work to heater.
• Do not alter heater. Keep heater in its original state.
• Do not use heater if altered.
• Turn off propane supply and unplug heater when not in use.
• Use only original replacement parts. This heater must use design-specific
parts. Do not substitute or use generic parts. Improper replacement parts could
cause serious or fatal injuries.

THEORY OF
OPERATION
The Fuel System: The hose/regulator assembly attaches to the propane gas
supply. The propane gas moves through the solenoid valve and out the nozzle.
The Air System: The motor turns the fan. The fan pushes air into and around
the combustion chamber. This air is heated and provides a stream of clean, hot air.
The Ignition System: The direct spark ignitor (DSI) sends voltage to the
ignitor. The ignitor ignites the fuel and air mixture.
The Safety Control System: This system causes the heater to shut down if the
flame goes out.

PROPANE
!
Propane gas and propane tank(s) are to be furnished by the user.
SUPPLY
INSTALLATION
Use this heater only with a propane vapor withdrawal supply system. See Chapter
5 of the Standard for Storage and Handling of Liquefied Petroleum Gas, ANSI/
NFPA 58 and/or CAN/CGA B149.2. Your local library or fire department will have
this booklet.
The amount of propane gas ready for use from propane tanks varies. Two factors
decide this amount:
1. The amount of propane gas in tank(s)
2. The temperature of tank(s)
The chart below shows the number of 100 pound tanks needed to run this heater.
Do not operate this product with any tank smaller than 100 pounds.
Temperature (°F) At Tank
32° 20° 10° 0° -10° -20°
Number of tanks 2 2 3 3 (Use larger tank)
Less gas is vaporized at lower temperatures. You may need two or more 100
pound tanks or one larger tank in colder weather. Your local propane gas dealer
will help you select the proper supply system. The minimum surrounding-air
temperature rating for this heater is -20°F (-29°C).
WARNING
Review and understand the warnings in the Safety Information
Section, pages 2 and 3. They are needed to safely operate this
heater. Follow all local codes when using this heater.
!
WARNING
Test all gas piping and connections for leaks after installing
or servicing. Never use an open flame to check for a leak.
Apply a mixture of liquid soap and water to all joints. Bubbles
forming show a leak. Correct all leaks at once.
1. Provide propane supply system (see Propane Supply above).
2. Connect POL fitting on hose/regulator assembly to propane tank(s). Turn POL
fitting counterclockwise into threads on tank. Tighten firmly using wrench.
