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 (3.78 Liters) of fuel in the tank. When filling the
heater, use at least 2 gallons (7.57 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 ex-
tended storage periods, drain the fuel tank of any moisture
or condensation.
4.
Locate heater at a safe distance from combustible materials.
Model MHC80KT is 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.
HEATER START UP
1.
Turn thermostat to lowest setting, and 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.
Notes:
• 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".
HEATER SHUT DOWN
1.
Push "On/Off" switch to "Off" position. For extended
shutdown, unplug heater from power source.
RESTART AFTER SAFETY SHUTDOWN
1.
Toggle switch to "OFF" position, wait 5 minutes. Restart.

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.
FUEL PRESSURE ADJUSTMENT SCREW
(located at the rear of the heater)
ADJUSTMENT PROCEDURE
1. Fill fuel tank.
2. Start heater.
3. Locate the pressure adjustment screw and pressure tap,
pictured above, located on the back of the power pack
assembly and accessible by the handle of the heater.
4. Remove and the rubber cap over the fuel pressure adjustment
screw.
5. Using a flat bladed screw driver, turn the pump pressure
adjustment screw:
• clockwise
to increase pump pressure
• counter-clockwise
By using the installed pressure gauge you may quantitatively
calibrate the pressure. The manufacturer's recommended pump
pressures are in the specifications chart on page 3.
6. The desired qualitative burner characteristics are that 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.
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.
