CAUTIONS
A temperature exceeding 100
o
F in the boiler room may cause premature failure of
electrical components on the boiler control panel.
The water chemistry in the boiler must be kept within limits outlined in this manual. Failure
to do so will likely cause premature boiler pressure vessel failure and poor steam quality.
Boiler feed water temperature must be 140
o
F or greater to prevent corrosion fatigue
cracking at the feed water nozzle.
The bolts that connect the boiler shell to the rails need to be loosened slightly before the
boiler is warmed up to allow thermal expansion of the pressure vessel. Failure to do so
will create unwanted pressure vessel stress.
NOTES
After installation is complete and prior to operation the pressure vessel should be cleaned
or boiled out per instructions included in this manual.
The normal water level is approximately the center of the water gauge glass.
To ensure that your Fulton Steam Boiler is kept operating safely and efficiently, follow the
maintenance procedures set forth in this manual.
It is normal for the boiler safety relief valve to weep water if the boiler is operated above
90% of the valve setpoint (i.e. weep will occur for a 100 psig valve if boiler is >90 psig).
To ensure the continued safety and efficiency of the boiler, the schedule of maintenance
outlined in this section should be adhered to.
The boiler blow off operation should be done a minimum of once during the day when the
boiler is at 10 PSIG or less.
After a new Fulton Boiler has been in operation for several months, pieces of burned metal
will be found in the space at the bottom of the boiler. These pieces of metal are the
remains of a light gauge metal form which was used during manufacture for forming the
