condensate outlet of the individual boiler and must
remain fl ooded by being at least 5 ½” below the outlet
of the condensate drain trap.
10. Connect 1 1/2” drain outlet to an appropriate waste line
following applicable codes. The 11/2” drain connection
on the condensate drain must be the highest point
prior to going to the drain. Failure to keep drain
piping lower than this point will result in overfl ow of
the condensate drain. Slope the drain pipe away at a
minimum pitch of 1 inch (25.4 mm) for every 12 feet
(3.65 m).
11. Attach a 1/4” water supply to the compression fi tting
on the fl oat. The water line must be connected to an
uninterruptible supply. Fulton recommends connecting
it before the “Fast-Fill” valve to the boiler supply but
after the back fl ow preventer to avoid contamination
of a potable water supply. Maximum allowable water
pressure to the compression fi tting is 100 PSI.
Venting
Adhere to the following venting requirements:
1. The boiler can be installed with either sealed
combustion or a conventional venting arrangement.
With either venting confi guration, the diff erence in
pressure readings at the boiler exhaust connection
and air intake connection cannot 2.0” W.C.
This equates to 70 feet (21.3 m) and 8 elbows when
combining the distances on the air intake and exhaust
with the piping diameters matching the standard
connections.
2. The pressure at the boiler exhaust connection must not
exceed 0.04” W.C. negative. This pressure must remain
relatively constant throughout the operation of the
boiler.
3. The boiler should not be operated with a negative
pressure in the boiler room (unless there is sealed
combustion [intake piped outside]). Pay particular
attention to other equipment installed in the boiler
