Fulton Companies Gas Fired Steam Boiler VMP-49.5

Boiler started and generating not more than 10 PSI (.703 kg/cm2) of steam?

Tap water turned on to blow-down separator?

Boiler blow-down valves opened for approximately 10 seconds?

Tap water to blow-down separator shut off?

Water column and the water gauge blow-down valves opened for approximately 5 seconds?

WARNING! Make sure main power switch is off before starting work

1. Cleaning the water gauge glass

CAUTION! Do not clean the gauge or gauge glass while pressurized or in operation

a. Clean the water gauge glass using a commercial non-abrasive glass cleaner. Use diluted acids such as hydrochloric (muriatic) acid when regular cleaners do not seem to work. Do not use wire brushes or any other abrasive materials which could scratch the glass. If any leakage is evident, replace the gaskets

b. Always replace the high impact plastic gauge glass protector which is standard on all Fulton Boilers

3. Check scanner or flame rod and ignition electrodes

4. Check starter contacts. Burned or pitted contacts should be replaced. Do not use sand paper or file to clean

5. Clean water traps and strainers in fuel lines

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

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;

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
