OPERATING INSTRUCTIONS

 The venting system should be inspected at the start of each heating season. Check the

vent pipe from the boiler to the chimney for signs of deterioration by rust or sagging joints.
Repair if necessary.

 Remove the vent pipe at the base of the chimney or flue and, using a mirror, check for

obstruction.

 The lever of the pressure relief valve, shown in Figure 17, on page 16, on the boiler

should be operated periodically to make sure that it is functioning properly. The pressure
relief valve should open before the water pressure exceeds the 30 lb. reading on the gauge.
If this pressure is exceeded and the pressure relief valve leaks water when the boiler is
operating at normal pressures, it should be immediately replaced. Corrosion can build up
rapidly at the valve seat and prevent its functioning as a safety device.

START-UP AND ADJUSTMENT OF OIL BURNER (See oil burner instructions for

nozzle and electrode setting).

A. Check oil burner nozzle to make certain it is tight in adapter. Burner mounting bolts

should be tight.

B. Check electrode setting, as they may have been jarred out of position during

transportation.

C. Lubricate burner motor and circulator motor if required. Some circulators are water

lubricated and do not require oiling.

D. Set room thermostat to call for heat, or jump thermostat contacts on the boiler control.
E. Open all oil line valves.
F. Turn service switch on. Burner should start.
G. On one pipe fuel systems only, vent pump as soon as burner starts. Allow oil to run

until all traces of air in the suction line disappear.

H. Turn 

“OFF”

 burner and install pressure gauge port on pump.

I. Start burner again and check oil pressure for 140 lbs. Adjust if necessary.

 CAUTION:

 

   DO NOT SET FIRE VISUALLY.

Instruments are the only reliable method to determine proper air adjustments. An

improperly adjusted burner causes soot and high fuel bills because of incomplete
combustion of the fuel oil. This in turn may require excessive boiler maintenance, service
costs, and in some instances, house cleaning or redecorating. A competent service
mechanic should be consulted to make the proper adjustments with a smoke tester, CO

2

indicator and draft gauge. Bacharach or Dwyer test kits include these instruments.

INSTRUCTIONS TO OBTAIN PROPER OPERATION

OF THE BOILER-BURNER UNIT

A 1/4" diameter slot is provided in the inspection cover plate to take draft readings in the

combustion chamber. See figure 17, on page 16.  A 1/4" diameter hole will be required in
the flue pipe between the boiler and barometric damper (if used) to take draft, CO

, smoke

and temperature readings. Adjust air shutter on oil burner to obtain a “trace” of smoke.
Measure CO

 at this point. Increase air adjustment to lower CO
