OPERATING PRECAUTIONS
This is a propane, direct-fired, convection 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 fitting, it sinks to the floor, 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 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.
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. DO NOT light or operate heater unless the shells are fully
extended and locked into position. See enclosed assembly
sheet for instructions.
4. Use only propane gas.
5. Use only VAPOR WITHDRAWAL propane supply. If there is
any question about vapor withdrawal, ask your propane
dealer.
6. Mount the propane cylinders vertically (shutoff valve up).
Secure them from falling or being knocked over and protect
them from damage.
7. Locate propane containers at least (USA) 7 ft. (2.13m) for
MH80CV and 9 ft. (2.7m) for MH200CV (Canada)10 ft. (3m)
from the heater and do not direct exhaust toward
containers.
8. 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.
9. For indoor use only. Area must be well ventilated. Figure 1.
(also see "Operating Precautions").
10. 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.
11. Install the heater such that it is not directly exposed to water
spray, rain and/or dripping water.
12. Maintain minimum clearance from normal combustible
material (like paper). Figure 2.
13. Due to the high surface and exhaust temperatures, adults
and children must observe clearances to avoid burns or
clothing ignition.
14. Operate only on a stable, level surface.
15. Do not use with duct work. Do not restrict inlet or exit.
16. Do not move, handle or service while hot or burning.
17. Use only in accordance with local codes or, in the absence of
local codes, with the Standard for the Storage and Handling
of Liquefied 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 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, 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.
• 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.
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 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.
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!
