Operating Instructions and Owner’s ManualMr. Heater |Kerosene Forced Air Heater

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 or #1 fuel oil. Never use gasoline,

naphtha, paint thinner, alcohol or other fuels of any kind.

4. For indoor use only. Use only in well ventilated areas.

Provide at least 2 sq. ft. of opening near the floor and

2 sq.ft. of opening near the ceiling. (Also see "Operating

Precautions").

5. Install the heater such that it is not directly exposed to

water spray, rain and/or dripping water.

6. Maintain minimum clearance from normal combustible

material (like paper) at least 8 ft. from the heater outlet and

3 ft. from the top, sides and inlet. Locate 10 ft. from canvas

or plastic coverings and secure them to prevent flapping or

movement.

7. Due to the high surface and exhaust temperatures, adults

and children must observe clearances to avoid burns or

clothing ignition.

8. Never use in areas normally for habitation and/or where

children may be present.

9. Operate only on a stable, level surface.

10. Do not use with duct work. Do not restrict inlet or exit.

11. Use only the 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).

12. Use only a properly grounded 3-prong receptacle or

extension cord.

13. Do not move, handle or service while hot or burning.

14. Use only in accordance with local codes and federal

ordinances.
