alled in place at the Factory. Attach thermo-altimeter
in 1/2" tapping in top front of boiler. Install 3/4" x close nipple in
3/4" top connection with 3/4" x 3/4" x 1/2" Tee. 3/4" Tee opening for
installation of the relief valve and 1/2" opening for expansion tank.

_WIRING_

Controls are all in place and wired at the factory except connection to
circulator.

_REGULATING OIL PRESSURE_

Standard nozzles furnished with the burner will produce the stamped
rated capacity when used with Commercial Standard No. 2 Fuel Oil, and
operated with a pressure of 100 lbs. per square inch. The standard
setting of the fuel unit is 100 lbs. Due to difference in tank
elevations, the pressure should be adjusted at the time of start up.

_FUEL LINES_

Care should be employed when attaching the oil lines to the fuel unit.
Overtightening or twisting will twist the pump-motor mounting plate and
put a stress on the motor bearings.

_START UP PROCEDURE_

General:

1. Make certain that correct voltage has been supplied to
motor and control circuit.

2. Insure that outside air openings are provided in the
boiler room for ventilation, and for admission of air
for combustion. The free area of such openings should
not be less than 7 square inch opening per 100,000 Btuh
burner input, or more as required by local codes.

3. Check to see that flue, wiring and water level are in
order.

4. Start burner fan motor to prime pump. If pump does not
pick up oil within a few minutes, prime the pump with
lubricating oil. Do not allow pump to run more than a
few minutes without additional lubrication.

5. Check oil pressure and adjust if necessary. (See
REGULATING OIL PRESSURE).

6. Set air shutters. (See ADJUSTING BURNER) Refer to Figure 1.

7. Generously lubricate the front motor bearing with SAE #20
oil.

_ADJUSTING BURNER_ (See Figure 1)

Positioning of the nozzle in relation to the face of the cone and the
electrodes in relation to the nozzle are very important, also the face
of the cone in relation to the face of the choke ring must be set
according to the chart for each rate.

If the air shutter openings are too large the oil may not ignite.

1. This setting will vary somewhat depending upon the grade
of oil being used or if No. 1 is used instead of No. 2.

2. The approximate burn
