Operating Controls

The following specifications, data, equipment and operating
descriptions apply to typical Vertical Boiler units. These
sections are provided for general information purposes only,
and do not necessarily reflect the specific details of individual
systems.
At commissioning, the operation of all safeties and interlocks
should be verified. Setpoints of all pressure and temperature
switches as well as the programs for all programmable
controls (pressure controls, pressure limits, operating controls,
servo motors etc.) should be recorded for future reference.
Contact the Fulton Service Department with any questions
regarding the proper operation, set points and verification
procedures for these controls.

Burner Settings

Burner combustion settings:
ƒ Boiler is fully test fired at the factory, please refer to the
test fire sheet for combustion information.
» P0 set point is typically between P1 and P2 on
combustion curve.
–
NOTE: Pilot pressure range is to be 2.5" w.c. to 3.5" w.c.
» Lower O2 settings can reduce burner mesh life.
» Higher O2 settings will reduce the overall
efficiency of the burner.
ƒ Boiler pressure controller is Yokogawa UT-32A for the
VSRT 9.5-125 and a Fulton PLC Controller for the
VSRT-250.
* Please refer to the PURE Control manual for the
VSRT-250
Burner combustion adjustment guidelines:
Up
Fan Speed Adjustment More O2, More Input
Gas Servo Adjustment More Input, Less O2
Air Servo Adjustment More O2, Less Input
SKP-25 Adjustment More Input, Less O2
