SPECIFICATIONS
OPERATING PRECAUTIONS
This is a kerosene, direct-fired, forced air heater. It's intended
use is primarily temporary heating of buildings under con-
struction, 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 ade-
quate 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.
