OPERATING PRECAUTIONS
This is a natural gas, direct-fired, forced air heater. It's intended
use is primarily temporary heating of buildings under
construction, alteration or repair.
If natural gas leaks from a connection or fitting, it mixes with
the surrounding air, forming a potentially explosive mixture.
Obviously, gas leaks should be avoided, so set up the gas
supply with utmost care. Read enclosed Odor Fade Sheet
for additional information about detecting gas leaks. Leak
check new connections or reconnections with a soap and
water solution and follow all connections instructions herein.
This heater was designed and certified for use as a
construction heater in accordance with ANSI Standard Z83.7/
CGA 2.14-2000. Check with your local fire 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.
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 natural gas.
4. Provide at least 5" W.C. but not over 1/2 psig to the heater
inlet (regulator inlet).
5. Use an appropriate hose or flexible connector not over 10 ft.
(3.05m) in length.
6.Operate the heater only with the 4" W.C.regulator
provided by the factory.
7. For indoor use only. Area must be well ventilated. Figure 1.
(also see "Operating Precautions").
8. If at any time gas odor is detected, IMMEDIATELY
DISCONTINUE operation until the source of gas has been
located and corrected.
for additional information about detecting gas 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). 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 ductwork. Do not restrict inlet or exit.
15. Use only the electrical power specified. The electrical
connection and grounding must comply with National
Electrical Code - ANSI/NFPA 70.
16. Use only a properly grounded 3-prong receptacle and
extension cord.
17. Do not move, handle or service while hot or burning.
18. Use only in accordance with local codes.
Read enclosed Odor Fade Sheet
Forced Air means that a blower or fan pushes the air through
the heater. Proper combustion depends upon this air flow;
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.
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 flow 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 specification section of the heater’s manual,
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
heater dataplate, or contact the Scheu Products Company 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.
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 fire 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 firefighters
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.
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.
• 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.
• Always be sensitive to the slightest gas odor. 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.
• 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!
