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 ex-
tended storage periods, drain the fuel tank of any moisture
or condensation.
4. Locate heater at a safe distance from combustible materials.
Models 50 & 75 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.
HEATER START UP
HS50K: Plug the heater into a grounded 1 15V, 60 Hz, 1 Ø
1.
outlet.
HS75KT, HS125KT, HS175KT & HS210KT: 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 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

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. #26) in the
exploded parts drawing. The pressure adjustment screw
is located at the rear of the heater, in the air filter housing
cover (slotted adjustment screw approx.10 o'clock position).
4. The plug directly under the adjustment screw can be used to
install a pressure gauge. It is not a second adjustment screw.
5. 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".
6. 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.
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
