burning fuel-air mixture.
Operation of the heater is simple. It involves
. i the £
three basic systems. (See figure 1.) The rest of the air from the fan passes over and
around the combustion chamber. At the front of the
heater it mixes with the hot air coming from inside the

C. MODEL DIFFERENCES
1. The two heaters covered in this manual are
similar in construction and alike in principle. The
Deluxe heaters use a control system which consists
ofalight-sensitivecell, a relay, anda circuit break-
er which will shut the heater off if it fails to ignite, or
if itruns out of fuel. An accessory kit is available to
convert standard heaters to Deluxe operation. (The
operation of the control system is explained more fully
in Section V, Service and Repair Instructions, Para-
graph N.).
2. Athermostatcontrol kit, Part No. HA-1000
is available as anaccessory for use with these heaters.
The thermostat can be setfor any temperature between
30 and 90 F, and will cycle the heater on and off to
maintain the surrounding air at the desired tempera-
ture. At its OFF position, the thermostat shuts the
heater off. At its ON position, it causes the heater to
operate continuously.
D. CONTROL SYSTEM DESCRIPTION
1. Description .
The control system used in Deluxe heaters is
designed to shut the heater off in case it does not ig-
nite, or in case the flame should go out during opera-
tion.
The control consists of three main parts: (1)
A light-sensitive cell which "sees" into the combustion
chamber; (2) A control relay whose coil is controlled
by the cell; and (3) A circuit breaker whose internal
heating coil is controlled by the relay contacts.
2. Operation.
When the heateris first plugged in, the heat-
ing coil inside the circuit breaker starts to warm up.
If no ignition takes place, the circuit breaker
will trip. When it trips, it shuts off all power to the
heater.
A2815-00
After a trip-out, the circuit breaker must be
manually reset by pressing the red button.
If ignition takes place, the cell "sees" the
flame. Itthenallows enough current to flow to operate
the control relay. The relay breaks the circuit to the
internal heating coil in the circuit breaker, and the cir-
cuit breaker's main contacts will then stay closed to
keep the heater operating.
If the heater should lose its fire during oper-
ation, the circuit breaker will trip after a short time,
shutting off all power to the heater.
E. POWER REQUIREMENTS
The heaters are manufactured for use on 115
volt, 60 cycle power.

SECTION II
OPERATION
A. OPERATING CAUTIONS
1. Usetheheater in a well-ventilated area only.
A partly-opened door or window near the heater will
give enough ventilation. We donot recommend the use
of this heater as a source of heat in sleeping quarters.
2. Use ONLY kerosene or No. 1 fuel oil. DO
NOT USE GASOLINE, AS IT IS VOLATILE AND
DANGEROUS. Do not use No. 2 or No. 3 fuel oil, as
they contain tars which will contaminate the heater.
3. Usethe heater only on the specified electrical
| power. This is given on the heater instruction plate.
4. Plug the heater into a grounded receptacle, or
use a grounding adapter. Be suretheheater is ground-
ed whenever it is in operation and whenever you are
working on it.
5. Keepthe heater at least 4 feet from any com-
bustible material.
6. Donotusethe heater in the presence of flam-
mable vapors like those from paint or gasoline.
7. Donotadd fuel while the heater is operating.
WARNING
The motor has an automatic thermal over-
load protector. It may stop due to low
voltage or overload, then RESTART auto-
matically. Be sure to disconnect the heater
service cord before removing the upper
shell or inspecting the motor.
B. EXTENSION CORD WIRE SIZES
Be sure to use an extension cord of the proper
size to assure adequate voltage at the heater.
Length of cord (feet) 100 200 300 400 500
Wire Size (AWG) 14 12 10 8 6
C. FUEL
Be sure the tank is clean. Fill it with clean
kerosene or No. 1 fuel oil ONLY. Do not use any
other fuel.
When the heater is operated at very low temp-
eratures (beyond 10 F below zero), the fuel may con-
geal. |
To prevent this, add a non-toxic anti-icer to the
fuel. Follow the mixing instructions contained on the
anti-icer container.
D. STARTING
1. Power Supply. Be sure thatthe power avail-
able to the heater matches that shown -on the instruc-
tion plate, in both voltage and frequency (cycles).
2. Heaters Without Thermostat. The heater
will normally ignite as soon as it is plugged into the
outlet.
3. Heaters With Thermostat. Set the temper-
ature dial of the thermostat or thermostat accessory
to the desired temperature or to the ON position.
| ‚a. Ifthe dial is set to the ON position, the
heater should ignite immediately and will operate con-
tinuously.
'А2816-01
b. I the dial is set to a temperature set-
ting, the heater should ignite immediately, providing
the surrounding air is cooler than the setting of the
dial. The heater will operate until the temperature
of the air reaches the dial setting, then will shut off.
When the surrounding air temperature falls below the
dial setting, the heater will start.
4. Heaters With Safety Controls.
a. If a thermostat is used, set it as de-
scribed above. If the heater does not ignite immed-
iately, or if it has no thermostat and does not ignite
as soon as plugged in, proceed as follows:
b. Press the red reset button on the rear
of the heater. The heater should start immediately.
с. Ifthe heater fails to start, the red but-
ton will pop out within 15 to 45 seconds, depending on
surrounding temperature. If it pops out, wait from
three to five minutes for the control circuit breaker to
cool, then press the red button again, after checking
for the reason the heater did not start.
d. Deluxe heater will generally restart
after they are shut off, without pressing the red re-
set button.
E. STOPPING
To stop the heater, unplug the heater cord from
the outlet. (If the heater has a thermostat, set the
dial to OFF.)

SECTION HI
MAINTENANCE
Maintenance consists of the simple operations the
owner or user of the heater can perform to keep the
heater running and in good condition. If ordinary main-
tenance fails to return the heater to good operating
condition, refer to Section IV in this manual for check-
ing and trouble shooting. See Figure 2 for maintenance
points.
A. FUEL TANK MAINTENANCE
Drainthe fuel tank after every 150 hours of oper-
ation, and flush it out with clean fuel. Refill with fresh
clean fuel.
B. AIR FILTERS
1. Check and clean the intake air filter often.
The filter needs cleaning if you can see a film of dust
on it. It will need cleaning more often if the heater is
operated in dustv air, See Figure 3,
2. To clean the intake air filter, simply pull it
out of the housing. Wash it with a mild detergent and
hot or cold water. Dry it thoroughly, and replace it
in the housing.
CAUTION: DGC NOT CIL tie filter element,
3. Replace the output air filter once each heating
season.
4. Toreachthe outputair filter, remove the four
screws which attach thefilter housing end cover. Re-
move the output air filter. See Figure 4.
NOTE: Cleaning the output air filter may cause a
change in the air pump output pressure. If
the heater burns improperly after cleaning,
have the air pump pressure checked. See
Section V, paragraph L.

C, REMOVING UPPER SHELL
WARNING
With the upper shell removed and the service
cord plugged in, the heater can be dangerous.
Always unplug the heater when performing
the following maintenance operations.
Remove the upper shell by removing the eight
screws (4 on each side) that hold the upper shell to the
lower shell. Lift the upper shell off.
To replace the upper shell, align the eight holes
located along its lower edge over the eight speed nuts
on the lower shell, and install the screws.
D. CLEANING THE FAN
Cleanthe fan blades after every 500 hours of op-
eration, or whenever you see that they are getting
dirty. Abuild-upof dirtwill reduce the air supply and
cause faulty operation.
To clean, wipe the blades with a cloth moistened
with kerosene or solvent. Be careful not to bend the
blades. Dry the fan thoroughly.

immediately, protect it from damage until it is re-
installed.
4. Install the plug if burner head maintenance is
notrequired. Install the plug into burner heads which
retain the plug with a screw so that the white dot on
the plug (just below the knurled surface) is in line with
the retaining screw. The spark plug gap must be
across the nozzle spray pattern.
G. CLEANING THE FUEL FILTER
The fuel filter is in the tube which leads up from
the fuel tank to the burner. Clean it twice each sea-
son, or if the Trouble Shooting Chart indicates.
1. To remove the fuel filter, loosen the hex nut
attaching the filter tube to the burner head, then loosen
the air tube and spark plug lead.
2. Remove the screws attaching the combustion
chamber to the lower shell. Liftthe combustion cham-
ber only enough to pull filter element and tube from
the fuel tank. Withdraw the filter element out of the
tube. Rinse it several times in clean fuel.
3. Blowtheelementdry, with a gentle stream of
compressed air, through the large end. Use care to
prevent damaging the filter element with air pressure.
4. If the filter element is damaged or lost, it
must be replaced with a new element. NEVER oper-
ate the heater without the element in place. Failure to
use the filter element may result in clogging and per-
manent damage to the nozzle.
5. Insertthe fuel filter element into the tube mak-
ing sure that it seats properly in the tube. Instali the
flared nut onto the tube. Lift up on the combustion
chamber and insert the filter element and tube into the
fuel tank. Attach the combustion chamber to the lower
shell, then position the filter tube carefully to seat on
the male connector and thread the flare nut to secure
thefilter and tube. Reconnect air line and spark plug
lead.

REPLACEMENT
1. Besuretheheater cord is unplugged, and re-
move the lead wire from the spark plug. Remove fuel
filter from burner head. Disconnect the air line from
the fitting in the right side of the nozzle adapter.
2. Loosenthe screws that fasten the burner head
to the rear of the combustion chamber.
3. Remove the nozzle carefully, using a socket
wrench. Hold the nozzle adapter with another wrench
while removing the nozzle.
CAUTION
Do not attempt to open the nozzle passage
with a steel drill, a wire or any other tool,
as you will damage it beyond repair. Protect
the nozzle face from damage while the burner
is out of the heater. This is important!
4. Soak the remaining parts of the burner head
assembly for one hour in non-flammable liquid clean-
ing agent. (DO NOT use kerosene or fuel oil). Blow
drythrough the face (OUTLET) end ONLY. See Fig-
ure 8.
5. Re-check the spark plug electrode setting
See Paragraph F of this
Section.

SECTION IV
TROUBLE SHOOTING
A. GENERAL
If normal maintenance fails to keep a heater in
good operating condition, it probably requires repair
or replacement of some parts. Examine it and test-
fire itto gain first-hand knowledge of why the service
might be needed.
This section tells how to examine and test-fire the
heater. It also contains a Trouble Shooting Chart for
help in diagnosing heater troubles and finding the re-
medies.
B. EXAMINATION
1. Check the fuel tank for sludge and water. If
you find it, expect to find a dirty nozzle and/or fuel
filter.
2. Spinthefanto be sure it turns freely. If it is
stiff, lookfor a worn or dry bearing on the fan-end of
the motor, or for a binding pump rotor.
3. Checktheheater for dirt and foreign materials
around the pump, fan, and air filters. Be sure the
heater is reasonably clean before test-firing it.
4. Check the heater cord for obvious breaks or
other unsafe conditions. I the cord is doubtful, re-
pair it or install a new one before test-firing.
C. TEST-FIRING
1. Clean the fuel tank and fill it with at least 3
gallons of fuel. A minimum of 3/4 gallon of fuel must
be in the tank for proper test-firing.
2. Clean the air intake filter.
(See Section III).
3. Checkand adjust the air pressure, as described
in Section V, paragraph L.
NOTE: It is not possible to test-fire a heater
properly if this adjustment cannot be
made.
4. Allow the heater to run for 15 minutes. Ob-
serve its operation during the test-run. _
5. After makingthe pressure check, adjustment,
and test-firing, remove the gage and reinstall the plug.
CAUTION: Tightenpluguntil sealed. Use soapy
water to check for sealing. Do not
overtighten.
6. Iftroubles show up during the test-firing, re-
fer to the Trouble Shooting Chart for remedy.
D. TROUBLE SHOOTING
The following chart lists problems, " Possible
Causes" and "Remedy", to correct the problem, or
tells you a section and paragraph number where to
find detailed instructions for correcting it.
In trouble shooting, remember that the air pump
is part of the fuel system, because the air it supplies
но
lifts the fuel from the tank and pushes it through the
nozzle.
NOTE: Besure to follow all cautions and warn-
ings. They will help you prevent damage
to the heater or injury to yourself.

SECTION V
SERVICE AND REPAIR INSTRUCTIONS
A. GENERAL
This section covers replacement of parts, repair
and rebuilding of heater components, and the making
of adjustments. Check to be sure the maintenance of
the heater has been done, before going into the more
extensive service operations.
Whenever a part needs to be replaced, you can
identify it on the exploded view in the Parts List por-
tion of this book, Section VI. Order any needed part
by name and part number.
B. SPECIAL TOOLS, EQUIPMENT, AND
SUPPLIES
The following tools, equipment and supplies should
be available for complete servicing of the heater.
1. Air Gage, Part No. M9148, or any gage with
a 15 pound pressure range and 1/4 pound divisions,
able to indicate 4-1/4 pounds accurately, plus fittings
for installation into a 1/8-inch standard pipe-threaded
hole.
2. Oil Burner Nozzle Wrench, or any deep 5/8-
inch socket wrench.
3. Cleanfuel, either kerosene or No. 1 fuel oil.
. 4. Non-flammable, non-toxic liquid cleaning sol-
vent.
WARNING
Alwaysuse solventinawell ventilated area.
9. Compressed air is advisable, but not ab-
solutely necessary.
C. THERMOSTAT ACCESSORY
If a thermostat accessory is being used and you
suspect that it is faulty, check as follows:
A2307-01
-15-
1. Turn the knob from OFF to ON, slowly,
through the full range of the thermostat, two or three
times. If the heater does not start, proceed as fol-
lows: |
2. Takethethermostat accessory out of the cir-
cuit by unplugging the heater from the thermostat ac-
cessory.
3. Plug the heater service cord into an outlet.
If the heater operates properly, the thermostat ac-
cessory is defective and must be replaced.
D. REMOVAL OF UPPER SHELL
It will be necessary to remove the upper shell in
order to perform the rest of the service operations on
the heater. See Section III, paragraph C.
E. TRANSFORMER
WARNING
To begin the transformer test, first be
sure the heater is not plugged in. Then,
when power is required, be EXTREMELY
careful when checking the transformer. A
transformer in good condition produces
VERY high voltage at the output terminals.
Check the transformer as follows:
1. Connect the transformer lead to a properly
gapped spark plug. The gap should be 0.050 inch,
plus or minus 0.005 inch. See Figure 6.
2. Establish a good ground between the spark
plug and the heater. Be careful not to let any part of
your person become a portion of the ground circuit.
3. Plug theheater cord into an outlet of the pro-
per voltage. Observe the spark between the plug's
electrodes. If the ground is good and a spark does not
jump between the electrodes, the transformer is de-
fective. Replace it. —
4/72
4. To replace the transformer, take out the two
screws which attach it to the motor mounting bracket.
Make sure that the new transformer mounting tabs are
free of paint, to assure a satisfactory ground.
5. Reinstall the attaching screws, and make
wiring connections in accordance with Figure 9.
6. Snap the spark plug lead tightly onto the plug
terminal, to prevent its coming loose when the heater
is moved.
F. CHECKING THE MOTOR STARTING CIRCUITS
In case the motor fails to start when the cord is
plugged in or the thermostat is set to call for heat,
check the motor and its starting circuit components as
described in the following paragraphs.
WARNING
The motors contain an automatic thermal
overload protector. This may stop the motor,
due to overload or low voltage, then RESTART
it automatically. Be sure to disconnect the
heater before inspecting the motor.
1. Mechanical Check. Spin the motor by turning
thefanblades by hand. If the motor turns freely, make
the electrical check as described in paragraph 2. Any
stiffness of the motor indicates mechanical troubles.
See "Motor Service, " paragraph G of this Section.
2. Electrical Check.
The heaters have 1/6 horsepower motors and
separate starting relays. (See the Wiring Diagrams,
Figure 9).
NOTE
The starting relay is "position - sensitive"
and must be tested in the same position as
when installed in the heater (with the con-
tacts on the bottom).
(1) Take the relay out of the heater by removing
the screw which holds its bracket to the left side of
the lower shell near the motor.
A2822-00
-16-
CAUTION
Avoid touching the bare wires or the exposed
wire terminals.
(2) Take the black motor wire off its terminal
of the starting relay. Touch this wire to the terminal
of the red motor wire at the relay. The motor should
start. As soonas the motor reaches operating speed,
remove the black wire from contact. The motor should
continue to run. |
(3) HK the motor starts, install a new relay, and
reconnect the wiring according to the Wiring Diagram,
Figure 9.
(4) Failure of the motor to start could result from
any of the following, assuming that all other circuits
in the heater are operating correctly. |
(а) Internal fault in the motor, such as
burned-out stator, or failure of thermal overload pro-
tector.
(b) Failure of the external starting relay.
(5) I the motor fails to start and the relay is
found not to be the cause of failure to start, remove
the motor and install a new or rebuilt motor. Send the
defective motor to the nearest motor manufacturer's
service station for repair, or order a replacement
motor from the Master Service Parts Department.
NOTE
When sending the motor away for repairs,
remove the fan, the air filter housing, and
the pump end cover. Remove the pump rotor,
and the carbon blades, but do not disturb the
pump body, which is the ring attached to the
end of the motor. (See paragraph K for pump
service instructions).
G. MOTOR SERVICE
1. Applyafew drops of oil to the fan-end bearing
of a stiff motor. If this fails to correct the starting
difficulty, rebuild the pump, as described in para-
graph K of this Section.
2. If rebuilding the pump does not eliminate the
motor stiffness, send the motor to the nearest motor
manufacturer for repair.
3. Whenever a motor has been replaced, be sure
to adjust the pump rotor clearance as described in
paragraph K-4 of this Section, before reassembling
the motor into the heater.

H. FAN SERVICE
Replace a damaged or bent fan. Do not attempt
repair except as a temporary emergency measure.
Loosen two setscrews to remove the fan from the mo-
tor shaft.
Be sure the replacement fan has the same blade
pitchas the fan that was removed. This is important
in order to retain the air flow and combustion charac-
teristics of the heater.
Position the fan on the motor shaft. Location
shown in Figure 10.
I. FUEL FILTER SERVICE
1. Remove the fuel filter from the heater and
clean it, as described in Section III, paragraph G.
2. Before reinstalling the fuel filter, check the
rubber bushing where it enters the fuel tank. Be sure
the bushing is in good condition -- not cut or cracked.
Replace a damaged bushing.
3. Reinstall the fuel filter according to Section
HI, paragraph G. Replacefilter parts which are dam-
aged or if anair tight connection cannot be made. Re-
place connection.
" A2823-00
-17-
J. BURNER HEAD SERVICE
1. Take out the spark plug and remove the burner
head. Clean the entire burner head, as described in
Section II, paragraph H.
2. If there is any sign of damage to the nozzle,
or if it is impossible to clean out the nozzle by blowing
compressed air into it through the outlet-end, replace
with a new nozzle. Always blow a nozzle out thoroughly
withair, from the outlet-end, before installing it into
the burner.
CAUTION
NEVER try to open a nozzle passage with a
drill. Any change in the size or shape of the
passage will damage the nozzle, beyond repair.
Donot disassemble the nozzle, as flow char-
acteristics are changed by disassembly. Pro-
tect the passage from damage whenever you
work on the burner or nozzle.
3. Always install a new rubber sleeve whenever
you install a nozzle into the burner. The sleeve is the
partthat helps maintain the needed pressure difference
between the air and fuel chambers of the burner head.
If bubbles have appeared in the fuel tank during oper-
ation, the rubber sleeve is probably leaking and should
be replaced.
4. Be sure the seal washer, spring, and second
seal washer are in place on the nozzle before you in-
stall the rubber sleeve.
5. When seating the nozzle firmly against the
burner head, do not apply too much pressure with the
wrench, or the nozzle could be distorted.
6. Adjustthe sparkplug gap as explained in Sec-
tion III, paragraph F.
K. AIR PUMP REPAIR
NOTE
Because of the close tolerances and critical
positioning of the parts, we recommend that
only a skilled serviceman attempt any repair
of the air pump.
The heater's air pump consists of a rotor with
four carbon blades rotating inside a pump body. The
rotor is driven directly by the motor, and is supported
by the ball-bearing end of the motor. One of the pump
end plates is the motor's back end plate. The other
pump end plate is part of the housing for the air intake
and outlet filters.
Handle all pump parts with care and keep them
clean. The parts are made with close tolerances.
Dirtand oil on pump parts will hinder the performance
of the pump.
If pump repair is required, you may order a com-
plete pump package, or individual parts, as shown in
the Parts List, Section VI.
5/71
1. Disassembly.
CAUTION
Do not take the pump apart any further than
youneedto in order to reach the parts which
must be replaced.
a. Remove the end cover and take out the in-
take and outlet air filters and the lint filter. Disconnect
the air line from the male connector.
b. Hold a clean, dry cloth under the pump,
and remove the six screws that hold the end cover to
the pump body. Catch the carbon blades in the cloth,
if they fall out as the pump body is removed.
c. Take all four carbon blades out of the
rotor. Pull the rotor and the spring off the motor shaft.
2. Replacing Carbon Blades.
a. Wornor sticking carbon blades cause loss
of air pressure. I the blades are worn, or are stick-
ing inthe rotor slots, replace them. (It is not neces-
sary to remove the rotor or the pump body to replace
the carbon blades.)
b. Blowdustfrom rotor slots, end cover and
pump body using compressed air. DO NOT immerse
parts in cleaning solvent.
с. Install the carbon blades into the slots.

3. Replacing the Rotor.
Use a new rotor only if deep grooves or uneven
wear appear on the surfaces. Check the insert for
wear, and replace it if worn or loose.
To remove the rotor, first remove the pump body.
4. Reassembly of Air Pump.
a. Install the insert in the pump rotor as
shown in Figure 11, then assemble rotor on the motor
shaft. When installing the rotor, take care to keep it
perpendicular to the motor shaft. Attach the pump
body to the motor with the two recessed screws which
were removed to take it off.
b. Adjustthe pump body to provide 0.005 to
0.006 inch clearance at the point shown in Figure 11.
Measure the clearance with a feeler gage. Spin the
motor by hand to be sure the rotor does not rub on the
pump body. The proper clearance must be maintained.
Be sure the recessed screws are tight after adjusting.
c. Imsertcarbonblades as described above.
d. Mmstall the end cover, using the six screws
which were removed. Reconnect the air line.
L. ADJUSTMENT OF PUMP PRESSURE
1. Remove the plug from the air filter housing,
and install the pressure gage (listed in paragraph B
of this Section) into the hole. See figure 12.
2. Starttheheater. (You do not need to have fuel
in the tank for this pressure check and adjustment).
3. Pump pressure must be 4 psi plus or minus
1/4 pound. If the pressure is not within this range,
adjust the pressure relief valve.
4. To adjust pump pressure, screw the valve
stem in to raise the pressure; out to lower it.
5. Removethe gage and replace the plug. Tighten
pluguntil sealed. Use soapy water to check for seal-
ing. Do not overtighten.
M. REASSEMBLY OF HEATER
1. Put the heater back together in the reverse
order of disassembly.
2. Checkall wiring to be sure it agrees with the
wiring diagram. Be sure all electrical connections
are tight.
3. Tighten the connections at both ends of the
air line, and tighten the connection where the fuel
filter is assembled to the burner head.
5/71
Install gage finger tight, plus one
turn. Check for leakage before
setting air pressure.
Figure 12. Checking and adjustment of
Air Pump Pressure

4. Make sure the electrode lead is snapped onto
the spark plug and the transformer output terminal.
2. Besure all parts are in place and the screws
are tight before attempting to use the heater.
N. CONTROL SYSTEM SERVICE
Since no adjustment is possible on the parts of
the control system, service is limited to cleaning the
glass face of the light-sensitive cell, cleaning the dirt
from the exposed contacts of the relay (if the contacts
are exposed), and replacing defective parts of the sys-
tem with parts that are known to be good.
O. FINAL CHECK
Put at least two gallons of fuel in the fuel tank
and test-fire the heater for a few minutes, after all
service has been completed, to be sure it will operate
satisfactorily.
