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.

UNPACKING

OPERATING INSTRUCTIONS

1. Remove all protective material which may have been
applied to the heater for shipment.

2. Remove heater from carton.

3. Check the heater for possible shipping damage. If any
damage is found immediately notify the dealer from whom
you purchased the heater.

ASSEMBLY (For 125,000 and 175,000 BTU/hr models only)

Wheel and handles are found in the shipping carton along
with mounting hardware. The wheels, axle and mounting
hardware are in a package. Tools required are a 5/16"
nutdriver, 3/8" open or adjustable wrench and standard
pliers.

1. Assemble the wheels onto the wheel support frame as
follows:
a. Install one of the cotter pins into the hole on one end of

axle.

b. Slide the large washer, then wheel onto the axle next to

the cotter pin.

c. Slide a small washer, spacer, small washer onto the

axle next to the wheel.

d. Slide the partially assembled axle through the wheel

support frame.

e. Slide the small washer, spacer, and small washer

onto the axle next to the wheel support.

f. Slide the wheel then large washer onto the axle and

hold in place with the remaining cotter pin.

g. Install the caps over the larger washers to finish the

wheel assembly.

2. Position the heater on the wheel support frame assembly
with the exit end over the wheels.

3. Use eight screws and nuts to attach the handles to the top
of the tank flange. The screws will go through the handles,
tank flange and wheel support frame. Install the nuts and
finger tight only until all nuts are installed.

4. Tighten all the nuts.

5. Attach cord caddies to handles using No. (14) & No. (5)
screws and nuts.

PREPARING FOR OPERATION

1. Check the heater for possible shipping damage. If any is
found, immediately notify the factory.

2. Follow all of the "Precautions".

3. Fill the fuel tank with clean kerosene, No. 1 fuel oil or No. 1
diesel fuel only. Kerosene is recommended for use when
the temperature drops below 0°F (-18°C). 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. Model K75 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
think and extending 3 ft. or more beyond the heater in all
directions.

START

1. Turn thermostat to lowest setting. Plug heater into a well
grounded 115V, 60HZ, 1Ø 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.

In cold weather, starting may be improved by holding a
finger over the end of the pressure adjusting screw until the
heater starts. This unit is equipped with a circuit breaker
located near the power cord. If the unit does not start, check
to see that the reset button is pressed in.

STOP

1. For a short duration shutdown, press toggle switch to "OFF"
position. For extended shutdown, unplug the heater.

RESTART AFTER SAFETY SHUTDOWN

1. Wait 5 minutes.

2. Push reset button.
