Check:
• Electrical terminals in the control panel and on all electrical components.
• Pipe fittings and unions.
• Tubing connections.
• Nuts, bolts, screws.
Before operating pumps, metering heads, and compressors, make certain that reservoirs are properly filled with
the specific lubricant. Open all necessary oil shutoff valves. Do not run compressors, pumps, or metering units
without oil.
Before connecting electrical current to any component, be sure the supply voltage is the same as that specified
on component nameplates.
Before burner operation, be sure all motors are rotating in the correct direction.
Before firing, make sure that the refractory flame cone is properly sealed to the burner mounting flange and the
boiler front plate.
Make certain that the operator in charge is properly instructed in the operation and maintenance procedures.
Before opening the gas shutoff valves, read the regulator instructions carefully. Open the shutoff valve slowly to allow
inlet pressure to build up slowly in the regulator until it is fully pressurized. Opening the shutoff valve quickly will
damage the regulator. Do not exceed the regulator pressure ratings.
Lubricating oil is drained from the air-oil tank before shipment. Before attempting to start the burner, add oil to the
recommended level.
The burner refractory cone is air-cured only. Heat-curing must be initiated at initial startup. Run the burner at low fire
for a period of 6 to 8 hours before starting to gradually increase the firing rate. Failure to do so will result in damage
and cracks in the refractory.
