the cooling cycle.
14. The boiler is furnished with a probe type low water
cutoff . No fi eld 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.
15. 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
fl oor 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.
16. Before fi lling the boiler clean and fl ush the system
to remove any debris. Clean and fl ush old piping
thoroughly before installing the boiler. Consider
installing a strainer ahead of the boiler.
Install Condensate Drain
The condensate drain kit is intended for use 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 12 MM BTU/hr) through a common header. See
Figure 7.
Adhere to the following for installation:
1. An uninterruptable water supply is required and shall
be connected to the 1/4” compression fi tting on the
drain fl oat. The water supply maintains a water level in
the drain kit to prevent the fl ue 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 fl ue gas emission into the boiler
room.
2. Keep the cover on at all times, except during
maintenance of the drain. This drain should be
monitored and checked regularly in your Pulse
maintenance schedule.
