k) The boiler is furnished with a probe type low water cutoff. No field piping is required. If the
probe does not sense water, the boiler will shut down and a red indicator will be
illuminated on the control panel.
l) The boiler is not provided with external drain connections. A drain valve must be installed
near the inlet connection to the boiler and piped to a suitable floor drain. A Boiler Drain
Assembly can also be purchased from Fulton. This Boiler Drain Assembly must be
installed near the inlet connection to the boiler.
m) Before filling the boiler clean and flush the system to remove any debris. Clean and flush
old piping thoroughly before installing the boiler. Consider installing a strainer ahead of
the boiler.
12. Condensate Drain Kit
Caution
Do not install the boiler in an uncontrolled environment where the condensate will
be subject to freezing temperatures.
a) The condensate drain kit is intended to be utilized with any size pulse unit supplied by
Fulton. The 3/4” condensate drain on the pulse unit will be connected to the 1” inlet on
the drain kit. One or more drain lines may be connected to this inlet (maximum of 8 total
per drain kit) through a common header.
b) An uninterruptable water supply is required and shall be connected to the 1/4”
compression fitting on the drain float. The water supply maintains a water level in the
drain kit to prevent the flue gas from entering the boiler room through the condensate
connection. The 1 1/2” connection shall be piped to an appropriate drain for disposal. If
the water supply must be temporarily disconnected, the boiler(s) must be turned off to
prevent accidental flue gas emission into the boiler room.
c) The cover should be kept on at all times, except during maintenance of the drain. This
drain should be monitored and checked regularly in your pulse maintenance schedule.
