Fulton Companies Gas Fired Steam Boiler VMP-150

Close downstream shut off valve

Start boiler and check flame signal on pilot, lock programmer into pilot hold

Adjust air and gas regulator as needed to obtain a strong pilot signal

Slowly open downstream shut off valves and take the flame programmer off of hold

1. Flame scanner adjustments are made with the detectors installed and the burner running. It is essential to obtain optimum flame signal detection for safe and continual operation of the control relay

2. If a scanner is inoperable, it may prove the detector is working and only an adjustment to the pilot flame is needed to improve the signal

3. If the scanner is found to be defective, replace

NOTE: The scanner is located on the outside edge of the burner top plate for 40, 80, and 100 HP

4. For the RM7800 Series use a keyboard display module or volt meter. The flame safeguard will require a 1.25 VDC signal to pull in the main flame. Then a maximum signal should be obtained on main flame (5.0 VDC)

5. Adjustments to establish a good signal may include the following items

a. Primary and secondary air adjustments

b. Increasing the pilot gas through the pilot gas regulator;

Boiler is cool with little or no pressure showing on the steam pressure gauge

Boiler blow-down valves are open

Water level in the water gauge glass

Burner shut off when water level fell below the low water electrode in the water column assembly and/or the boiler shell

Manual reset of the low water relay is required

Sign off on the weekly boiler check

NOTE: If it is determined that a servo motor needs to be replaced, the first step in this process is to verify the model number of the new servo motor is the same as the old servo motor

NOTE: The model number starts with the letters SQM and is displayed on a label on the side of the motor. Once the new motor has been verified to be correct, turn power to the boiler off

Turn off all electricity to the boiler

Remove the cover on the servo motor to be changed

Remove the green wiring plugs and the conduit termination point from the motor by pulling them towards you. A black grounding wire runs from the motor to the conduit termination point. Pull it off from the conduit termination point

Also note the location of the jumper on the left side of the motor

Loosen the allen screws on the motor end of the motor to valve coupling

Unbolt the motor from the mounting bracket and remove the motor

Turn the valve so it is in the closed position and can rotate clockwise to open

1. Have combustion (CO2, O2, CO) and input checked by responsible personnel

2. Dirty flues can cause air flow restrictions resulting in poor combustion and loss of efficiency. Clean flues as follows

a. Remove the outer flue cover plate

b. Remove inner plate and turbultors

c. Remove clean out plugs at lowest part of unit and clean the bottom of combustion chamber

d. Remove all soot from the top, and from the clean out plugs at the bottom with a vacuum cleaner

e. Replace clean out plugs carefully so as not to damage insulation and replace burner and flue cover plates

3. Flush boiler out if necessary. See Section 2 for proper procedure for "Cleaning the Pressure Vessel."

4. Provide annual inspection by a qualified ASME Boiler inspector;
