SAFETY PRECAUTIONS
This is a portable, indirect oil-fired air heater with closed
combustion chamber and connection duct for a stack to exhaust
combustion fumes.
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.READ AND UNDERSTAND THE INSTRUCTIONS IN THIS
HANDBOOKBEFORE USINGTHE APPLIANCE. The
electrical system to which the appliance is connected must
comply with current legislation. Installation requires a
minimum 15 A circuit breaker.
4.Always unplug the appliance before performing any
maintenance operations.
5.Before using the appliance, check the power cable. It must
not be bent, taut, stretched, crushed or damaged in any way.
6.The power cable connection must be made by qualified
personnel only. Use a AWG 12/3 SJT x 50' type of cable only
with an approved plug.
7.DANGER (BURNS)! Do not touch the exhaust gas outlet.
8.The appliance must be installed for industrial use only.
OPERATING INSTRUCTIONS
Start-up
1.To operate the appliance with remote thermostat, remove
the protective cap from the thermostat outlet (ill. 1 #1) and
insert the thermostat plug into the outlet. To operate without
thermostat, leave (or re-insert) the protective cap into outlet.
2.Fill the tank with clean fuel (Diesel #1, Diesel #2,
Kerosene).
3.Insert the power plug in a 115V ~ 60 Hz single-phase,
grounded power outlet. If the green light (ill. 1 #5) is ON, the
appliance has power. Electrical grounding is mandatory.
4.Connect the appliance to a stack of a flue to vent fumes to
the outside air.
5.To obtain a good draft (.04 in w.c.), the flue path must rise.
Avoid any bends or elbows in the initial section of pipe for at
least 10 ft. If the appliance is used in a closed environment
without stack, refer to the installation instructions.
6.For use with a remote thermostat set thermostat to
maximum temperature.
7.Move the switch (ill. 1 #3) to the "ON" position.
8.Adjust the thermostat to the required temperature (if
applicable).

The appliance must be thoroughly cleaned once a year to
assure correct combustion and long life.
In addition the following must be cleaned more often depending
on fuel and operating environment:
a) Oil atomization nozzle and associated filter - Unscrew the
nozzle from the burner head. Clean nozzle and filter with
compressed air.
b) Tank filter cartridge - The filter is located on the right side of
the heater above the tank. Open the filter glass, extract the
cartridge, blow compressed air and wash with kerosene.
Depending on the quality fo fuel used, replace the cartridge
if it is very dirty.
c) Electrodes - Distance between tips should be .12 inch.
Remove carbon deposits from electrode tips using a metal
brush.
d) Fan - Blow air on the fan blades through rear guard to
remove dust.
e) Inside of appliance - Open inspection panel. Blow
compressed air to remove dust from inner parts.
f) Photoelectric cell - Extract the photoelectric cell from its seat
near the burner head and clean the front glass surfact using
a light detergent. Take care to place the photoelectric cell in
the right position when reassembling.
g) Electrical - Make a periodic inspection of cables and
electrical connections by a qualified personnel.
INSTALLATION INSTRUCTIONS
GeneralInstructions
1.Never install the appliance in environments containing
flammable materials or in places with a risk of fire or
explosion.
2.The approximate area that can be heated is 28,300 ft³ for
K150-FAI model and 53,000 ft³ for K275-FAI model. 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.

fume venting to the open air through a stack, an external air
delivery of approximately 47 cfm must be assured for good
combustion.
4.If the appliance is installed in a closed environment and
fumes are not vented through a stack, good ventilation of the
environment must be assured.
5.Good ventilation is guaranteed in the case of an hourly air
exchange equal to 2.5 times the volume of the heated area.
To obtain this, an opening for air inlet from below and an
opening for air exhaust from above, with a free surface of at
least (8.6 ft² each), must be provided.
6.The appliance is intended for use in the construction
industry and agriculture. All safety regulations applicable to
these industries must be complied with. In particular, the
following safety distances from flammable materials or
components must be assured:
Side: 2 ft. Air inlet side: 2 ft.
Top: 5 ft. Hot air outlet side: 10 ft.
