Fulton Companies Gas Fired Steam Boiler VMP-130

1. Cleaning the gas burner assembly

a. Disconnect the gas head from the burner by disconnecting the union. Remove the burner plate screws. Withdraw the burner assembly and clean the flame rod and ignition electrode

b. Check that the settings of the flame rod, if applicable, and ignition electrode correspond to those in the illustration below

c. Reassemble the burner assembly and check the flame rod setting or scanner setting

d. Check the combustion efficiency of the burner and adjust if necessary

e. Clean probe on top of boiler shell and probes in water column. There must be no pressure on the boiler during the removal of the probes

f. Check refractories for soot or breakage and inspect the stainless steel ring (50-100 HP only)

g. With the boiler under no more than 15 PSI pressure, check that the steam safety valve is operating by lifting the lever

2. Drain condensate tank and clean tank by flushing with hose. Check float valve operation

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

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

Sign off on the Fulton LoNOx Burner Pilot Adjustment

Start the boiler and generate not more than 10 PSI (.703 kg/cm2) of steam

Turn on tap water to blow-down separator

Open the boiler blow-down valves for approximately 10 seconds, then close the valve

Shut off tap water to blow-down separator

Blow down water column each morning when boiler is at 10 PSI (.703 kg/cm2) by opening the water column and the water gauge blow-down valves for approximately 5 seconds, then close the valves

If the feed water is being treated by compounds, make sure that this treatment is carried out carefully and according to the manufacturer's instructions

When first starting the boiler each day, make sure ignition and burner are working properly

Check water level in sight glass

Check to be sure feed water pump is working

Remove the burner plate and top plate assembly up and out of the air to air heat exchanger

Remove the stainless steel combustion ring from the furnace

Remove the clean-out plugs from the bottom sides of the boiler

Break off the top holding clips that were used to keep the refractory in position during shipping

Break up the top and/or bottom refractories and remove the pieces from the boiler through the clean-out plugs

Round and bevel the outer edges of the new refractories

Lower the bottom refractory down the furnace with wire fastened around the refractory in three positions

Install the top refractory in the same manner as the bottom refractory

Seal the outer edges of the top refractory with insulcrete
