Operating Controls
 Water Relief Valve
The Water Relief Valve releases extra pressure.
 Water Outlet Valve
The Water Outlet Valve serves as the isolation valve for the system.
 Temperature Control
The Temperature Control is a digital indicating control used to turn the boiler on
and off , and to control the fi ring rate when the boiler is modulated. The digital
display will show both the boiler process temperature and the boiler setpoint.
 Operating Temperature Aquastat
The Operating Temperature Aquastat controls the working temperature of the
boiler. This an ASME CSD-1 code control which will turn the boiler off when the
water temperature exceeds its setpoint. It is an auto-reset control.
 High Limit Aquastat/High Temperature Limit
The High Limit Aquastat/High Temperature Limit prevents over-temperature
conditions. It is an ASME CSD-1 code control which includes a manual reset
feature for over-temperature. Press the manual reset button when the
temperature drops to reset the control.
 Air Safety Switch
This switch is controlled by the pressure of air entering the burner. This
switch proves that the blower fan is delivering combustion air.
 Probe Type Low Water Cut-Off
The Low Water Cut-Off shuts down the unit when the water level is too low, after
a three-second time delay to prevent nuisance shut downs. Fulton boilers are
equipped with ASME CSD-1 Code controls which include a manual reset feature
on the burner low water cut off relay. Press the low water reset button to reset
the control, and the boiler will start.

WARNING
This boiler is equipped with an ignition
device which automatically lights the
burner. Do not try to light burner by hand.
Operating this equipment beyond its
design limits can damage the equipment
and can be dangerous. Do not operate the
equipment outside of its limits. Do not try
to upgrade the equipment performance
through unapproved modifi cations.
Unapproved modifi cations may cause
injury, equipment damage, and will void
the warranty.
Check daily that the equipment area
is free and clear of any combustible
materials, including fl ammable vapors
and liquids.
Do not tamper with safety features
provided by the operating controls.

CAUTION
Operation of the circulating pump for any
amount of time without fi rst bleeding will
result in equipment damage.
For all systems containing boilers or unfi red
steam generators, the water chemistry in
the boiler (generator) must be kept within
required limits. Failure to do so may cause
premature pressure vessel failure and poor
steam quality and will void the warranty.
