Fulton Companies Gas Fired Steam Boiler VMP-100

Warning: Ensure there is no pressure on the boiler during the removal of the probes

Clean probe on top of boiler shell

Note: Remove one probe, clean with very fine emory cloth and replace it before removing another to avoid mix ups

Probe cleaned and replaced correctly

For replacement purposes, installed probe lengths are indicated in the chart below. For a universally adaptable plug and probe which can be cut to length in the field to fit all boilers, order Part No. 2-20-017

Enter the part number for replacement probe

Sign off on the water probe cleaning

Warning: Adjustments are made with the detectors installed and the burner running.

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

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

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

Enter the VDC signal for the RM7800 Series.

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).

Adjustments to establish a good signal may include the following items

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

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;
