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~neonly,
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 con-
nected 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 inac-
cessible locations. Avoid running tubing against heating unit
and across ceiling or floor joists. If possible install under floor.
Specific informat~orlon piping, fuel unit connections, lift capa-
bilities, and tank installat~onsis provided in the instructions
of the fuel unlt manufacturer.
COMBUSTION AIR
Burner must be installed in area with adequate fresh air avail-
able 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~naaequatt 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.

UPGRADING OR CONVERSION
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.
Se-
cure 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 faci-
litated 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.
IMPORTANTCAUTIONS
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~onchambers 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~tha "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~lledw~th
clean No.
1
or No.
2
furnace oil. Crankcaseoil, waste oilor GASOLINE
should never be used. Water, rust, or other contam~nationin the fuel
supply system will cause malfunction and premature failure of the
~nternalparts of the fuel unit
POWER CIRCUIT
Be sure that burner and controls are w~redcorrectly and that the
line switch
IS
properly fused (20 amp). In Canada wiring to be
done inaccordance with the Canadian Electr~calCode, Part
I.
NOZZLE
Be sure that spec~fiednozzle
IS
Installed and that any covering
over nozzle is removed prior tostarting the burner.
NOZZLE AND ELECTRODE SETTING
Be sure nozzle and electrodes are pos~tioned
as
shown elsewhere
In these ~nstructlons Improper adjustment can result In oil

AIR TUBE INSERTION
The burner head should be
'A"
back from the Inside wall of the
combust~onchamber. Under no circumstances should the burner
head extend Into the combust~onchamber.
FUEL UNIT
Be sure that fuel unlt
IS
arranged for the type of 011supply 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~dedmay result In an alr lock w~th~nthe pump that w~ll
prevent 011from be~ng
delivered
to the nozzle See also Fuel Unlt

LINEOIL 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.
OILSHUTOFF VALVE
Install approved high qual~tyshutoff valves in 011supply 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-inshutoff 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~neto the burner.
