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.

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.
PREPARING FOR OPERATION
1. Check the heater for possible shipping damage. If any is
found, immediately contact the manufacturer at
800-251-0001.
2. Follow all of the “Precautions”.
3. Fill the fuel tank with clean kerosene. In extremely cold
weather, condensation may develop in the tank and it is
recommended that a tablespoon of de-icer be added for
each gallon (4 liters) of fuel in the tank. When filling the
heater, use at least 2 gallons (8 liters) of fuel. Be sure heater
is level and do not overfill. Use a funnel or can with a long fill
spout.
IMPORTANT: Before filling fuel tank the first time or after extended storage periods, drain the fuel tank of any moisture
or condensation.
4. Locate heater at a safe distance from combustible materials.
Models MH50KR & MH75KTR are not suitable for use on
wood floors or other combustible materials. When used, the
heater should rest on suitable insulating material at least 1
inch thick and extending 3 ft. or more beyond the heater in
all directions.
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 Adjustment
Problem: Heater does not have a strong consistent flame.
Heater smokes and spits raw fuel.
Nose cone does not get cherry red.
HEATER START UP
MH50KR: Plug the heater into a grounded 115V, 60 Hz, 1 Ø
outlet.
MH75KTR, MH125KTR, MH175KTR & MH210KTR: Turn
thermostat to lowest setting, make sure “On/Off” switch
is “Off”. Plug the heater into a grounded 115V, 60 Hz, 1 Ø
outlet. Turn thermostat to highest setting. Start heater by
pushing toggle switch to “On” position (light signifies switch
is in “ON” position). Adjust thermostat to desired setting.
Heater will cycle on/off as heat is required.
EXTENSION CORD REQUIREMENTS: Up to 100’ (30.5m) use
16 awg. conductor. 101’ - 200’ (30.5 - 61.0m) use 14 awg.
conductor.
For all models:
• In cold weather (below 10° F), starting may be improved by
holding a finger over the vent hole of the pump adjustment
screw cap until the heater starts.
• This unit is equipped with an interrupt circuit. The reset is
integrated into the “On/Off” switch. If the unit does not
start, toggle the switch to “Off”, wait 5 min. and toggle
the switch to “On”.
1.
Adjustment:Pump pressure is too low.
Turn adjustment screw clockwise to increase pump pressure.
Problem:
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”.
HEATER SHUT DOWN
1.
MH50KR: Unplug heater from power source.
MH75KTR, MH125KTR, MH175KTR & MH210KTR: Push
“On/Off” switch to “Off” position. For extended shutdown,
unplug heater from power source.
RESTART AFTER SAFETY SHUTDOWN (MH50KR, MH75KTR,
MH125KTR, MH175KTR & MH210KTR) See page 7

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.).
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.
CAD CELL. Clean the glass portion of the cad cell with a soft
dry cloth.
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.
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
A hazardous condition may result if a heater is used that has been
modified or is not functioning properly.
When the heater is working normally:
* The flame is contained within the heater.
* The flame is essentially yellow.
* There is no strong disagreeable odor, eye burning or other
physical discomfort.
* There is no smoke or soot internal or external to the heater.
* There are no unplanned or unexplained shut downs of the
heater.
