F. Startup and Operation
When the installation is complete and all electrical, fuel, water, and vent stack connections are made, make
certain the connections are tight. The operator should become familiar with the burner, boiler controls and
components. Adjustment procedures should be reviewed prior to firing. The wiring diagram should also be
studied along with the operating sequence of the burner programmer. Check the electrical power supply for
accordance with the nameplate specifications for all motors and controls.
Read and understand starting instructions before attempting to operate the burner. The following checks must
be made:
BOILER
Check boiler water level. Be sure all boiler valves are installed correctly and positioned properly. Set the high
limit control slightly above the operating control. Set operating control at the desired temperature or pressure.
BURNER
For protection in shipment, the flame safeguard control chassis is shipped unmounted. Check all screw
connections before attaching flame safeguard chassis to base. The screw must be secure to assure low
resistance connections. The relay chassis is mounted on the subbase with a screw which, when tightened,
completes the connection between the subbase and chassis contacts. Press manual reset button to be sure
safety switch contacts are closed.
Check fuses in main panel and in the burner control cabinet. Check wiring to the burner control cabinet for
compliance with the wiring diagram and local codes. The control cabinet components are 120 volt. If a control
transformer is supplied, ensure that the supply voltage matches its primary voltage.
Check motor rotation by momentarily closing the starter or relay. Blower rotation is clockwise when viewed
from the drive end.
Check the pilot electrode setting.
Check 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 lever and manipulating by hand.
Check the air shutter and adjust low-fire setting.
FIRING PREPARATIONS
Check to make certain that all plugs, connections. linkages, etc., are tight. Prior to initial firing, oil flow and
pressure should be verified.
Gas Burners
A representative of the gas utility should turn on the gas. Determine by a test gauge upstream of the burner
regulator that sufficient pressure exists at the entrance to the gas train. The gas pressure regulator must be
adjusted to the pressure required and the pressure setting recorded.
On combination fuel models, set the selector switch to gas. On initial startup it is recommended that the main
gas shutoff cock remain closed until the programmer has cycled through pre-purge and pilot sequences to
determine that the main gas valve opens. Turn the burner switch OFF and let the programmer finish its cycle.
Check to see that the gas valve closes tightly.
On burners equipped with high and low gas pressure switches, set switch pressure actuating levels and record
settings for future service reference.
See the burner specification nameplate inside the control panel door for minimum and maximum input rate
and required manifold pressure.
