Force-Air Propane Construction HeaterOperating Instructions and Owner’s Manual
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 2.14-2000. 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 producing
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, modified or
operated with parts removed or missing. Likewise, safety
systems must not be circumvented or modified in order to
operate the heater.
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. Figure 1.
(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 it is not directly exposed to water
spray, rain and/or dripping water.
11. Maintain minimum clearance from normal combustible material
(like paper). Figure 2.
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 duct work. 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.
17. Do not move, handle or service while hot or burning.
18. Do not adjust the heater combustion tube elevation while
heater is running or hot. Adjustments to elevation should only
be made after the heater has cooled to touch.
19. 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.
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.

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.
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.
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.
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 properly 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!

SIZE AND CAPACITY OF PROPANE CYLINDERS
The charts below show the approximate size of the cylinder
required for these heaters. To use the chart:
WARNING: When using a thermostat controlled heater,
its exit area should be protected from personnel and
warnings posted of sudden startup.
1. Select the lowest air temperature expected (at the bottom of
the chart).
2. Move straight up to time of operation desired
(left side of the chart).
3. Read the cylinder size required.
All heaters should have: full cylinders
good air circulation
no frost on cylinders
Fuel Cyclinder Capacity: 100#
HOW MUCH HEAT DO I REQUIRE?
For economy, it is important to match input to that required. But
heat requirements often vary. For example, it usually takes a lot
more heat to get things warm than it does to keep them that way.
Likewise, outside air temperature usually changes during the day
so you may need more heat at night than you do in the daytime.
An approximation of the heat required can be found by using the
chart below.
