OPERATING PRECAUTIONS
This is a kerosene, direct-fired, forced air heater. It's intended use
is primarily temporary heating of buildings under construction,
alteration or repair.
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 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.
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 Kerosene. Never use gasoline, naphtha, paint
thinner, alcohol or other fuels of any kind.
4. For indoor use only. Not for use where exposed to weather.
5. Use in well ventilated areas, provide at least 2 sq. ft. (0.19
sq. m.) of opening near the floor and 2 sq. ft. (0.19 sq. m.)
near the ceiling directly to outdoors. Increase air openings as
marked for each additional heater.
6. Always keep combustibles, like paper and wood at least 8
ft. (2.4 m) from the heater outlet and 3 ft. (1.0 m) from the
top, sides and inlet. Locate 10 ft. (3.0 m) from canvas or
plastic coverings and secure them to prevent flapping
movement.
7. Caution: Due to the high surface and exhaust temperatures,
adults and children must observe clearances to avoid burns
or clothing ignition. Do Not Touch. Keep Children, Clothing,
and Combustibles away.
8. Install the heater such that it is not directly exposed to
water spray, rain and / or water.
9. Never use in areas normally for habitation and /or where
children may be present.
10. Operate only on a stable, level surface. (MH50K & MH75KT
– See wood floor warning).
11. Do not use with duct work. Do not restrict inlet or exit.
12. Use only with electrical power specified. 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).
13. Use only a properly grounded 3-prong receptacle or
extension cord.
14. Do not move, handle, or service while hot or burning.
15. Use only in accordance with local, state (provincial) or
National requirements, ordinances and codes.
