SCALE RELATED MAINTENANCE
Periodic maintenance is necessary to keep your boiler clean and efficient. It is recommended that
initially after three months of steamer usage you have your Vulcan Hart authorized servicer inspect the
boiler and perform the below listed maintenance and inspections. Local water conditions and steamer
usage will determine the frequency that this service must be repeated; however, a minimum
recommendation is once a year. This maintenance is not covered by warranty.
• Descaler — Automatic descalers are provided inside the boiler to hold minerals in a suspended state
so they can be flushed out. This descaler will be consumed. The rate of consumption depends upon
the chemical makeup of the feed water and the average volume of feed water required. An inspection
by service personnel is recommended until it is learned from experience what the normal life of the
descalers are under your operating conditions.
• Boiler Scale — Have the servicer inspect the boiler through the hand hole for lime build-up. Have
your servicer open the washout plug under the boiler and add water to flush out any loose scale.
If a build-up of scale is present that indicates the boiler should be delimed, have the servicer delime
the boiler at this time. If a water treatment system that has its own delime procedure is being used,
follow the procedures provided with the water treatment system.
• Boiler Drain Valve Strainer — Have your servicer clean the strainer screen as needed.
• Water Level Probes — Have your servicer inspect and clean the water level probes in the boiler.
WATER LEVEL GAUGE
Check sight glass assembly daily. The correct water level is approximately one inch of water in the
gauge glass.
Extremely murky water in the sight glass indicates bad water conditions. The boiler should be blown
down. If conditions persist, have the boiler cleaned by your Vulcan-Hart authorized servicer.
LUBRICATION
The door screw was factory lubricated with high-temperature grease, but will require periodic
lubrication. When the door screw is properly lubricated, the hand pressure required to seal the door
is greatly reduced and the life of the screw and nut are lengthened. The frequency of lubrication should
depend upon use. Lubricate monthly at first and let experience determine the frequency. A high-
temperature door screw grease can be obtained from Vulcan-Hart Company.
FLUE
When cool, annually check the flue to be sure it is free of obstructions.
BOILER INSPECTION PLATE
The plate must be removed for boiler inspection every 12 months according to state code. This must
be done by a boiler inspector.
