SPECIFICATIONS

CAUTION : CSA certified for use with only No. 1-K kerosene fuel.

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. 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

Be sure to follow advice about ventilation in the Safety Precautions section. 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. Recommended for use with No.1-K kerosene fuel. Factory tested for use with No.2-K kerosene, No.1 or No.2 Diesel, No.1 or No.2 fuel oil or JP8 Jet A fuel and these fuels may be used as well. Never use gasoline, oil drained from crank cases, naphtha, paint thinners, alcohol or any other highly flammable fuels.
2. Check the heater thoroughly for damage. DO NOT operate a damaged heater.
3. DO NOT modify the heater or operate a heater which has been modified from its original condition.
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 combustible 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. (MH50KR & MH75KTR – 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.

MAINTENANCE AND STORAGE

WARNING. To prevent personal injury, unplug the heater from the wall outlet before servicing. For maximum efficiency and trouble-free service, make the following periodic maintenance, cleaning and inspections.

Adjusting Pump Pressure
Due to varying fuel viscosities and normal component wear the pump pressure on this heater may need to be adjusted.

Adjustment Procedure

1. Fill fuel tank.
2. Start heater.
3. Locate the fuel pressure adjustment screw (ref. #29) in the exploded parts drawing. The pressure adjustment screw is located at the rear of the heater, in the air filter housing cover (approx.2” from the left side and 1” from the top). Remove and discard the rubber cap (ref. #4) to expose the screw.
4. Using a flat bladed screw driver, turn the pump pressure adjustment screw clockwise to increase pump pressure and/ or counter-clockwise to decrease pump pressure. Base pump pressures can be found in the specifications chart on page 3 of the “Operating Instructions and Owners’ Manual”.
5. For best results, the nose cone in the combustion chamber should be cherry red with no dark spots and the flame should not extend beyond the nose cone.

Improper Pressure Ad

• Problem : Heater does not have a strong consistent flame. Heater smokes and spits raw fuel. Nose cone does not get cherry red.
• Adjustment : Pump pressure is too low. Turn adjustment screw clockwise to increase pump pressure.
• Problem : Flame extends beyond the end of the heater.
• Adjustment : Pump pressure is too high. Turn adjustment screw counter clockwise to decrease pump pressure.

DAILY SCHEDULE

1. GENERAL. Make general visual inspection of heater for loose or damaged parts. Check nuts and bolts to insure against looseness caused by vibration or rough handling. Damaged parts should be repaired or replaced before using heater again. Check heater operation to be sure it is operating normally (See “Servicing” section for description of normal operation).
2. FILTERS. Dirty air or fuel filters will cause an imbalance in the air-fuel mixture. The best indication that this condition exists is an increase in odors or difficulty getting your heater to ignite. This heater should never be operated without the filters in place. If required, clean filters as described under “500 Hours” and “Annual Schedules”.

500 HOUR SCHEDULE

1. AIR INTAKE FILTER. Remove and wash the filter element with a mild detergent, dry thoroughly and replace. Do not oil the filter element. If your heater is used where there is considerable dust or dirt, clean as often as necessary (approximately every 50 hrs.).
2. REMOVE DUST. Clean heater twice a season (more often under dusty conditions). Remove accumulated dust from the transformer, burner, motor and fan blades with compressed air. Wipe area clean with a clean dry cloth. Inspect area to insure all foreign materials are removed, especially around the burner and combustion area.
3. CAD CELL. Clean the glass portion of the cad cell with a soft dry cloth.
4. NOZZLE. Accumulation of dirt from fuel and carbon from the compressor vanes will eventually fill up the passages in the nozzle, resulting in reduction of fuel and air flow. Pressure will gradually increase giving improper fuel-air mixture and excess odor and smoke. If this occurs, replace the fuel nozzle.
5. FUEL TANK. Clean twice a season (during frequently used periods, clean twice a month). Drain and flush the fuel tank with clean fuel oil.

ANNUAL SCHEDULE

1. AIR OUTPUT FILTER. Remove the air output filter and tap the contaminated side gently on a solid object to remove contaminates. Compressed air or liquids should not be used to clean this filter. Reinstall cleaned filter in filter body in the same position as it was when removed. If the filter appears extremely dirty, replace it with a new filter of the same type. When replacing the filter cover, be sure the gasket is firmly in place and the screws in the filter cover are tight to prevent air leaks.
2. FUEL FILTER. Remove the fuel filter from fuel line and direct compressed air through the filter in the opposite direction of fuel flow. Safety glasses should be worn when using compressed air.
3. AIR AND FUEL LINES. If the air or fuel lines are removed during cleaning, be sure all connections are tight before operating unit

STORAGE

Store the heater in a dry location free from fumes or dust. At the end of each heating season, clean the heater as described in the MAINTENANCE section. Drain and flush the fuel tank with clean fuel. The manufacturer recommends completely filling the tank with fuel for extended storage to minimize condensation inside the tank.

SERVICING
