OPERATING PRECAUTIONS
This is a propane, direct-red, forced air heater. It's intended use
is primarily temporary heating of buildings under construction,
alteration or repair.
Propane is heavier than air. If propane leaks from a connection or
tting, it sinks to the oor, collecting there with the surrounding
air, forming a potentially explosive mixture. Obviously, propane
leaks should be avoided, so set up the propane supply with utmost
care. Read enclosed Odor Fade and Propane Sheet for additional
information about detecting propane leaks. Leak check new
connections or reconnections with a soap and water solution and
follow all connection instructions herein. Also, ask your propane
dealer for advice on the propane application and supply installation
and ask him to check it if there are any questions.
This heater was designed and certied for use as a construction
heater in accordance with ANSI Standard Z83.7/CGA 2.14. Check
with your local re safety authority if you have any questions about
your applications. Other standards govern the use of fuel gases and
heat producting products in specific applications. Your local authority
can advise you about these.
Direct-Fired means that all of the combustion products enter the
heated space. Even though this heater operates very close to 100
percent combustion efficiency, it still produces small amounts of
carbon monoxide. Carbon monoxide (called CO) is toxic. We can
tolerate small amounts but not a lot. CO can build up in a heated
space and failure to provide adequate ventilation could result in
death. The symptoms of inadequate ventilation are:
• headache
• dizziness
• burning eyes and nose
• nausea
• dry mouth or sore throat
So, be sure to follow advice about ventilation in these operating
instructions.
Forced Air means that a blower or fan pushes the air through the
heater. Proper combustion depends upon this air ow; therefore,
the heater must not be revised, modied or operated with
parts removed or missing. Likewise, safety systems must not be
circumvented or modified in order to operate the heater.
When the heater is to be operated in the presence of other people
the user is responsible for properly acquainting those present with
the safety precautions and instructions, and of the hazards involved.
SAFETY PRECAUTIONS
1. Check the heater thoroughly for damage. DO NOT operate a
damaged heater.
2. DO NOT modify the heater or operate a heater which has been
modified from its original condition.
3. Use only propane gas.
4. Use only VAPOR WITHDRAWAL propane supply. If there is any
question about vapor withdrawal, ask your propane dealer.
5. Mount the propane cylinders vertically (shutoff valve up).
Secure them from falling or being knocked over and protect
them from damage.
6. Locate propane containers at least (USA) 7 ft. (2.13m), (Canada)
10 ft. (3m) from the heater and do not direct exhaust toward
containers.
7. IMPORTANT Use only the hose and regulator assembly
provided with the heater. Match the color stripe on the
hangtag attached to the hose assembly with the color on
the label located near the propane inlet fitting on the heater.
Inspect hose assembly before each use of the heater. If there
is excessive abrasion or wear, or hose is cut, replace with hose
assembly listed on parts list before using heater.
8. For indoor use only. Area must be well ventilated. Provide
minimum openings of 1/2 sq. ft. (.046 m²) near the oor
and 1/2 sq. ft. (.046 m²) near the ceiling (also see "Operating
Precautions").
9. If at any time gas odor is detected, IMMEDIATELY
DISCONTINUE operation until the source of gas has been
located and corrected. Read enclosed Odor fade and Propane
Sheet for additional information about detecting propane leaks.
10. Install the heater such that is is not directly exposed to water
spray, rain and/or dripping water.
11. Maintain minimum clearance from normal combustible material
(like paper) as follows: oor-0 ft. (0 m); outlet-6 ft. (1.83m);
sides-2 ft. (.61m); top-6 ft. (1.83m). Locate 10 ft. (3m) from
canvas or plastic tarpaulins or similar coverings and secure them
to prevent apping or movement due to wind action.
12. Due to the high surface and exhaust temperatures, adults and
children must observe clearances to avoid burns or clothing
ignition.
13. Operate only on a stable, level surface.
14. Do not use with ductwork. Do not restrict inlet or exit.
15. Use only the electrical power specied. The electrical
connection and grounding must comply with National Electrical
Code - ANSI/NFPA 70 (USA) and CSA C22.1 Canadian Electrical
Code, Part 1 (Canada).
16. Use only a properly grounded 3-prong receptacle or extension
cord (6 ft (1.83m) in length minimum).
17. Do not move, handle or service while hot or burning.
18. Use only in accordance with local codes or, in the absence of
local codes, with the Standard for the Storage and Handling
of Liqueed Petroleum Gases ANSI/NFPA 58 and CSA B149.1,
Natural Gas and Propane Installation Code.

ODOR FADE WARNING
WARNING
Asphyxiation Hazard
• Do not use this heater for heating human living
quarters.
• Do not use in unventilated areas.
• The ow of combustion and ventilation air must not
be obstructed.
• Proper ventilation air must be provided to support
the combustion air requirements of the heater
being used.
• Refer to the specication section of the heater’s
manual, heater dataplate, or contact the factory to
determine combustion air ventilation requirements
of the heater.
• Lack of proper ventilation air will lead to improper
combustion.
• Improper combustion can lead to carbon monoxide
poisoning leading to serious injury or death.
Symptom of carbon monoxide poisoning can
include headaches dizziness and difficulty in
breathing.
ODOR FADING - NO ODOR DETECTED
• Some people cannot smell well. Some people cannot smell
the odor of the man-made chemical added to propane (LP)
or natural gas. You must determine if you can smell the
odorant in these fuel gases.
• Learn to recognize the odor of propane (LP) gas and
natural gas. Local propane (LP) gas dealers will be more
than happy to give you a scratch and sniff pamphlet. Use it
to become familiar with the fuel gas odor.
• Smoking can decrease your ability to smell. Being around
an odor for a period of time can affect your sensitivity to
that particular odor. Odors present in animal confinement
buildings can mask fuel gas odor.
• The odorant in propane (LP) gas and natural gas is
colorless and the intensity of its odor can fade under
some circumstances.
• If there is an underground leak, the movement of gas
through the soil can filter the odorant.
• Propane (LP) gas odor may differ in intensity at different
levels. Since Propane (LP) gas is heavier than air, there may
be more odor at lower levels.
•Alwaysbesensitivetotheslightestgasodor.If you
continue to detect any gas odor, no matter how small, treat
it as a serious leak. Immediately go into action as discussed
previously.
FUEL GAS ODOR
LP gas and natural gas have man-made odorants added
specifically for detection of fuel gas leaks.
If a gas leak occurs you should be able to smell the fuel
gas. Since Propane (LP) is heavier than air you should
smell for the gas odor low to the floor. ANY GAS ODOR
IS YOUR SIGNAL TO GO INTO IMMEDIATE ACTION!
• Do not take any action that could ignite the fuel gas. Do
not operate any electrical switches. Do not pull any power
supply or extension cords. Do not light matches or any
other source of flame. Do not use your telephone.
• Get everyone out of the building and away from the area
immediately.
• Close all propane (LP) gas tank or cylinder fuel supply
valves, or the main fuel supply valve located at the meter if
you use natural gas.
• Propane (LP) gas is heavier than air and may settle in low
areas. When you have reason to suspect a propane leak,
keep out of all low areas.
• Use your neighbor’s phone and call your fuel gas supplier
and your re department. Do not re-enter the building or
area.
• Stay out of the building and away from the area until
declared safe by the firefighters and your fuel gas supplier.
• FINALLY, let the fuel gas service person and the reghters
check for escaped gas. Have them air out the building and
area before you return. Properly trained service people
must repair any leaks, check for further leakages, and then
relight the appliance for you.
ATTENTION - CRITICAL POINTS TO
REMEMBER!
• Propane (LP) gas has a distinctive odor. Learn to recognize
these odors. (Reference Fuel Gas Odor and Odor Fading
sections above.
• Even If you are not property trained in the service and
repair of the heater, ALWAYS be consciously aware of the
odors of propane (LP) gas and natural gas.
• If you have not been properly trained in repair and service
of propane (LP) gas then do not attempt to light heater,
perform service or repairs, or make any adjustments to the
heater on the propane (LP) gas fuel system.
• A periodic sniff test around the heater or at the heater’s
joints; i.e. hose, connections, etc., is a good safety practice
under any conditions. If you smell even a small amount of
gas, CONTACT YOUR FUEL GAS SUPPLIER IMMEDIATELY.
DO NOT WAIT!
