CHAPTER 3 Operation
3.1 — Preparations for Starting
When the installation is complete and all electrical, fuel, water, and vent stack connections are made, make certain said
connections are tight. The operator should become familiar with the burner, boiler controls, and components. To
identify controls and components, refer to contents of Chapter 1. Adjustment procedures given in Chapter 4 should be
reviewed prior to firing. The wiring diagram should also be studied along with the operating sequence of burner
programmer. Read and understand starting instructions before attempting to operate the burner. Before attempting to
start the burner, the following checks must be made:
Item Check
Boiler Check the boiler water level. Be sure all boiler valves are installed correctly and positioned
properly. Set the high limit control slightly above the desired temperature. Set modulating
controls at the desired temperature or pressure.
Burner Check the electrical power supply to the burner in accordance with the nameplate voltage on all
motors and the control circuit. Check the direction or rotation of the motors. Open the housing
to check the electrode setting. Check the gas pilot pressure at the pilot gas regulator. The
normal setting is 3” to 6” W.C.
For protection in shipment, the flame safeguard control chassis is shipped unmounted. Check
all screw connections before attaching the flame safeguard chassis to the base. The screw must
be secure to assure low resistance connections. The relay chassis is mounted on the sub-base
with a screw which, when tightened, completes the connection between the sub-base and
chassis contacts. Press the manual reset button to be sure safety switch contacts are closed.
Check the control linkage for proper movement of the air volume damper and fuel metering
components. This can be done by loosening the linkage at the actuator level and manipulating
by hand.
Check the air shutter and adjust low fire setting.
Oil-Air Tank (Lube Oil) Check the lube oil level in the air-oil tank. Inspect oil level regularly. Loss of oil will damage
the compressor. Fill the tank with non detergent SAE30 oil to a level midway up the sight glass.
Do not overfill the tank.
For a normal environment use SAE10 oil. Change oil every 2000 hours of operations.
