Dear Homeowner:
Over forty years of engineering and product development have
gone into your new oil burner. Its quality and
des~gn are unsur-
passed. Properly installed and maintained it
will
provide many years
of efficient, trouble-free operation. Please read
this
lnstructlon
M?nual
carefully, and give special attent~on to the
following
points.
-
An oil burner must have a generous supply of
combustion
air
to
operate properly. Please refer to the information in this manual for
details.
- NEVER attempt to use gasoline
In
your heating applmce. Gaso-
line is more combustible than fuel oil and could result in a
serlous
explosion. NEVER burn garbage or refuse In your heatlng appllance
or try to light oil by tossing burning mater~al into the heater

GENERAL INFORMATION
FUEL UNITS & TUBING INSTALLATION
Burners are most commonly installed with a single stage fuel
unit. This fuel unit, when connected with a supply
l~ne only,
is
satisfactory where the fuel supply is on a level with, or
above the burner permitting gravity flow of oil. When it is
necessary to lift oil to the burner, a return line should be connected between the fuel unit and tank. This requires insertion
of the "by-pass" plug into the fuel unit. If lift exceeds ap-
proximately 10 ft., a two-stage pump should be installed with
a
return line.
When
a
return line is used, with either single or two-stage
pumps, air is automatically returned to the tank making the
unit self-purging.
Use of continuous runs of
hcavy wall copper tubing is recom-
mended. Always use flare fittings. Avoid use of fittings in inaccessible locations. Avoid running tubing against heating unit
and across ceiling or floor joists. If possible install under floor.
Specific
informat~orl on piping, fuel unit connections, lift capa-
bilities, and tank
installat~ons is provided in the instructions
of the fuel
unlt manufacturer.
COMBUSTION AIR
Burner must be installed in area with adequate fresh air available to support combust~on.
Appliances located in confined spaces: The confined space shall
be providad with two permanent openings, one near the top
of the enclosure and one near the bottom. Each
openlng shall
have
a
free area of not less than one square inch per 1,000
Btu
per hour of the total input rating of all appliances in the
enclos~lre, freely communicating with interior areas having in
iu~n aaequatt infiltration from the outside.
WIRING
The wiring must be in accordance with the National Electric
Code and local codes and regulations.
Wiring diagrams are included in the heating
cjnit installation
instructions.

ATTACHING AIR TUBE COMBINATION
(CHASSIS PLAN ONLY)
If the air tube combination and oil burner chassis are pack-
aged separately, the assembly is completed
as
follows:
1.
Attach air tube to burner housing using four sheet metal
screws. (If using an adjustable burner mounting flange, first
attach flange to air tube.)
2.
Insert nozzle line electrode
as-
sembly into tube and position nozzle from head, using
'2'
dimension shown elsewhere in these instructions. Check to
be
certain nozzle and head are concentric.
3.
Secure escut-
cheon plate by tightening screw at side of housing.
4.
Secure nozzle line using bulkhead lock nut. When a knurled
lock nut is supplied, the recessed side is to face away from
burner housing.
5.
Attach connector tube (from pump to
nozzle line). With long air tube combinations, insertion of
the nozzle line electrode assembly into the air tube is facilitated by rotating the assembly
180° from its installed
position, inserting it partially into the air tube, and then
rotating it back to its proper position.
SETTING THE BURNER
Use a mounting flange or pedestal as required.
The end of the burner air tube should be
'A"
back from
the inside surface
of
the front wall of the combustion
chamber.
Insulate around air tube to prevent overheating of tube,
nozzle and components. Make sure that insulation and
cement do not obstruct face of burner head.
IMPORTANT CAUTIONS
FZEAD BEFORE STARTING
CAUTION:
STAINLESS STEEL COMBUSTION CHAMBERS
The higher temperature levels produced by high-performanct
flame retention burners may exceed the temperature ratings of
stainless steel combust~on chambers and can result in chamber
burn-outs.
Where
a
burner upgrading
IS
being made in a unit with a sta~nless
steel chamber, please observe at least one of these precautions:
1. Line the Chamber
w~th a "wet-pac" ceramlc liner.
2.
Adjust inlet alr to the burner so that the CO, level
IS
below
OIL
Before startlng the burner be sure fuel tank
IS
adequately f~lled w~th
clean No. 1 or No. 2 furnace oil. Crankcase oil, waste oil or GASOLINE
should never be used. Water, rust, or other
contam~nation in the fuel
supply system will cause malfunction and premature failure of the
~nternal parts of the fuel unit
POWER CIRCUIT
Be sure that burner and controls are
w~red correctly and that the
line switch
IS
properly fused (20 amp). In Canada wiring to be

Be sure that fuel unlt
IS
arranged for the type of 011 supply system
installed "One
P~pe" or "Two P~pe" Be sure that all connec-
tlons are t~ght
Fuel units generdlly requlre manual ventlng of alr when ~n~t~ally
started. Failure to vent the alr from the fuel unlt through the vent
plug
prov~ded may result In an alr lock w~th~n the pump that w~ll
prevent 011 from be~ng
delivered
to the nozzle See also Fuel Unlt
I\,flanufacturer's ~nstructlons
LINE OIL FILTER
Use an oil filter of generous capacity for all
~nstallat~ons. Install
inside the building between the tank shutoff valve and the burner.
For ease of servicing, locate the filter and
a
shut-off valve close to
the oil burner.
OIL SHUTOFF VALVE
Install approved high
qual~ty shutoff valves in 011 supply line in
accessible locations, one close to the tank and another close to oil
burner, but ahead of the filter. Note that some types of filters are
made with a built-in shutoff valve.
T
STARTING AND ADJUSTMENT PROCEDURE
Caution: Do not attempt to start the burner when excess oil has
accumulated, when
the furnace or boiler is full of vapour, or
when the combustion chamber
is
very hot.
1. Set thermostat substantially above room temperature.
2.
Open shut-off valves in the oil supply l~ne to the burner.
HOMEOWNER INFORMATION
3. Check ~n~t~al alr adjustment. Normally the bulk air band (3)
should be closed and the shutter
(21
part~ally open:
4.
Close line sw~tch to start burner. If burner does not start
-
immediately, re-set manual overload switches on motor and
control.
5.
Vent fuel unit
as
soon
as
burner motor starts rotating. To
vent, loosen vent plug while holding an empty container
under the vent opening to catch oil which will be expelled.
Dra~n at least
112
plnt of
011
from the pump then close the
vent plug. The
~gnit~on should be instantaneous with closing
the vent plug.
If the burner starts and runs but stops
agaln dur~ng the venting
operation,
Walt three to five minutes for the safety switch to cool
then re-set the manual switch and repeat the procedure until ignition
IS
obtained. Somet~mes after venting is accomplished and
oil is
Ignited, the fire will again go out. This probably means that
additional venting is necessary. Repeat the above venting procedure.
AIR ADJUSTMENT
Adjust air supply by loosening lock screws and moving air shutter
(2)
and if necessary the bulk air band
(3).
Allow just sufficient air to obtain
clean combustion determined by visual inspection. Reduce air supply
until flame tips appear slightly smoky, then increase air just enough to
make the flame tips appear absolutely clean.
DRAFT CONTROL ADJUSTMENT
When the burner air supply and draft are properly adjusted the combustion chamber draft will normally be
.01" - .02"
WC. Larger installa-
tions may require slightly greater draft.
F
FINAL ADJUSTMENTS
At this point a final adjustment should be made using suitable instruments for smoke spot and
C02 (or
02)
measurements. Unless
otherwise specified in appliance manufacturer's instructions, the unit
should be set as follows: After allowing
10
minutes for warm up, air
should be set so that the smoke number is zero or a trace; less than
no.
1
smoke is highly desirable and should never exceed this limit.
(Note: Occasionally a new heating appliance will require longer warm
up time in order to burn clean because of the evaporation of oil
deposits on the heat exchanger and other surfaces.
C02 measured in
the stack (ahead of the draft control) should be a minimum of
10%
for
knocked down appliances or retrofit applications and a minimum of
12%
for units with burners tested and supplied by manufacturers as a
package.
Tighten all locking screws after final adjustments are made.
The unit should be started and stopped several times to make sure
there are no significant rumbles or pulsations.
CHECKING THE CONTROLS
Check and
adjust all controls In accordance with the Control
Manufacturer's instruction sheets. Be sure the primary control
safety switch operates
proper1 y so that safety shutdown will oc-
cur in the event of equipment malfunction.
FINAL CHECKS
Be sure air shutter and draft control are locked
. . .
that there is
an ample supply of fresh air to the room in which the unit is lo-
p
cated, and there are no oil leaks.
INSTRUCTING THE HOMEOWNER
The operation and care of the heating system should be explained
to the home owner, including how to adjust the thermostat, necessity of air supply to the burner. care of the burner. and the
simple checks to make before calling for service if the burner fails
tn
nnnrate auntnmatirall\r
OIL SUPPLY
Do not allow the fuel tank to run out of oil. During the summt
be sure that your fuel tank is kept full; this will prevent conder
sation of moisture on the inside surfaces of the tank.
IF YOUR TANK RUNS DRY, ITMAY BE NECESSARY
TO MANUALLY VENT THE AIR FROM THE PUMP
AND LINES WHEN RE-STARTING THE BURNER.
-
COMBUSTION AIR SUPPLY
Your burner requires a generous amount of clean combustion a
in order to burn the fuel completely. Lack of adequate combu:
tion air may result in erratic operation of the burner or nois
combustion or fuel odors in the air.
Remember your need fc
outs~de air will be greatly increased if you have a vented dry€
in the basement or other venting fans in the home.
OILING MOTOR
Motor life will be increased by proper oiling. Use a few dropsa
non-detergent oil at both motor oil holes twice each year
FILTER
The line filter cartridge should be replaced every year to avoi
contamination of the fuel unit and atomizing nozzle.
AREA AROUND HEATING UNIT
Should be kept clean and free of any combustible materials
-
especially papers and oily rags.
NEVER
Burn garbage or refuse in your heating unit. Never try to ignite oi
by tossing burning papers or other material into your heater.
SERVICE INFORMATION
"Preventive maintenance" is the best way to avoid unnecessar)
expense and inconvenience. Have your heating system and burnel
inspected
at
regular intervals by a qualified service man. If diffi
culty occurs, follow these simple checks before calling the servicc
man.
1.
Be sure there is oil in the tank and valve is open.
2.
Be sure the thermostat is set above Room Temperature.
3.
Be sure main Line Switch
is
"ON" and fuses are not blown.
