Fulton Classic ICX or FB-F Vertical Tubeless Boilers (Steam) Oil Fired - Manual (Page 20)

The Blow-Off Valve— There are two
blow off valves on the boiler; the main
valve at the rear of the boiler and the
water gauge glass blow off valve.
The boiler blow off valve supplied
with the boiler should be screwed to
the blow off pipe at the rear of the
boiler and connected to a blow off
receptacle of approved design. This
should be done in accordance with
state and local codes.
The Feed Water Piping--
1) Provisions must be made for
adequate water supply and properly
sized piping. Piping must be done
in compliance with all local codes.
The following chart may be used as
a guideline for sizing.

2) When feeding the boiler using a
return system the city water pres-
sure should not exceed 40 PSI. A
pressure reducing valve should be
installed ahead of the return tank
above this pressure.
3) It is important that all piping be
lined up and not forced into
place. It is recommended that you
begin piping at the pump. If the
lines are ended at the pump, partic-
ularly if the last piece is cut too short
or long, the pump will be forced to
meet the pipe and strain or distor-
tion will result.
4) Do not use the pump as a piping
support. It is critical that the pipe be
independently supported near the
pump so no strain will be transmit-
ted to the unit.
5) Connect the feed water stop
valve to the feed water pipe at the
rear of the boiler and pipe it to the
return system.
The Water Column
Install the piping from the water col-
umn and water gauge glass to a
safe blow-off point.
