Boyertown Regal Oil Fired Furnace Variable Speed 2 Stage ECM Motor - Manual (Page 20)

Suction vacuum must be held to acceptable limits. THE VACUUM TEST IS WORTH THE TIME
REQUIRED TO MAKE IT. This problem becomes proportionately larger with underground tanks.
Connect vacuum gauge to oil pump. Suction vacuum must not exceed 10 inches of mercury for single
stage pumps and 15 inches for two stage pumps. It is preferable to stay below these limitations. When
the suction line is tight and properly installed the pump will hold its vacuum for a minimum of 60
minutes after shutdown.
Use an oil filter with the proper capacity to filter for all installations. Install the filter inside the
building between the tank shutoff valve and the burner. The filter cartridge should be replaced at least
once a year. The filter body should be thoroughly cleaned before installing a new cartridge.
Start-Up
Use number No. 2 fuel oil only. WARNING
Do not attempt to start the burner if excess oil has accumulated.
Do not use gasoline, crankcase draining or any oil containing gasoline.
This equipment must be adjusted and started only by a qualified service agency – an individual or
agency, licensed and experienced with all codes and ordinances, and who is responsible for the
installation and adjustment of the equipment.
1. Check that all safety devices are in place.
2. Check that thermostats are correctly connected and set.
3. Check that the inside of the furnace is free of any fuel residue or foreign materials and that the
refractory chamber has not been damaged.
4. Check oil burner nozzle to ensure that the right size and type is installed and tight in the adapter.
See preliminary settings for proper nozzle size and type.
5. Check electrode settings, as they may have been jarred out of position during transportation. See
oil burner instructions for nozzle and electrode setting
6. Check air setting to ensure that it matches the preliminary air settings as found in Table 9, Table
10, or Table 11.
7. Check that the Burner mounting bolts are tight.
8. Lubricate burner motor and circulator motor if required.
9. Open all oil lines valves.
10. Set room thermostat to call for heat.
11. Turn service switch on. Burner should start. On one pipe fuel system only you may have to bleed
the oil system. To bleed attach a clear plastic tube to the oil pump bleed port and allow oil to run
until all the air is out of the oil suction line feeding the oil burner. If air is still evident in the bleed
line you must check the oil lines, all fittings, filters and any other connections for tightness. See
burner and fuel pump manufacturers recommendations for proper bleeding of the fuel system.
CAUTION: DO NOT RUN THE PUMP DRY FOR MORE THAN FIVE MINUTES, AS
IRREPAIRABLE DAMAGE MAY RESULT.
12. Turn “OFF” burner and install pressure gauge and vacuum gauge into the proper ports on the
pump. See the burner manufacturer’s manual for location of ports.
13. Start burner again and check oil pressure. Adjust if necessary. See oil burner manufacturers’
instructions for pump adjustment.
