V/LNV Series Manual
3-3
Operation
When the conditions covered above and in Chapter 2 are assured, the burner is ready for firing.
3.1.5 — Burner Settings
To ensure reliable and safe burner performance, the location and gap setting of the electrode for direct-
spark igniters, and the relative positions of the burner nozzle, diffuser, and air baffle components must be
correctly set. The air damper blades must be adjusted, relative to the established flow rates, to provide the
correct amount of air for complete efficient combustion.
These items are preset at the factory, but must be checked prior to placing the burner into initial service, or
after conducting any service work that may have altered their position. Refer to Chapter 4 for instructions.
3.1.6 — Combustion Settings
Fuel and air flow rates are individually adjusted at low fire and at high fire to achieve rated heat input, firing
rate turndown, optimum efficiency, safe operation, and the ability to cope with environmental changes
(including air temperature, humidity, barometric pressure), and fuel property changes. Refer to the
nameplate inside the control panel for minimum and maximum fuel input ratings. Refer to Chapter 4 for
instructions.
3.1.7 — Test Equipment
The following tests should be conducted on site:
1.
Combustion analyzer with O
2
indication
2.
U-Tube manometer, or pressure gauge, to measure gas pressures (Main and Pilot), pressure and vacuum
gauge for the oil burners
3.
Inclined manometer to measure draft pressures
4.
Smoke spot tester for oil burners and CO analyzer for gas fired units
5.
Voltmeter/Ammeter
6.
Stack thermometer and thermocouples
3.2 — Electrical Interference Test
Prior to putting the burner into service, conduct the following test to ascertain that ignition spark will not
cause the flame relay to pull in.
Should a starting failure occur for any reason, combustible fumes may fill the combustion chamber. Never
attempt to re-light the burner under these conditions without first purging the chamber.
Read the flame safeguard manual and fully understand its content before attempting to operate this equipment.
If this instruction is ignored, serious injury or death may result.
