INSTALLATION VTG-IOM-2016-1214 SECTION 2
! WARNING
The exhaust vent installer should be
familiar with Federal Codes as well
as local codes and regulations.
4 CAUTION
An uninterruptible water supply is
required and shall be connected to the
¼” (U.S. only) compression tting on
the condensate drain. The water supply
maintains a water level in the drain kit
to prevent accidental ue gas emission
into the boiler room.
The minimum return water
temperature to the boiler is 140 F
(60 C) when ring on standard #2 fuel
oil. Failure to maintain this will void
the warranty.
 Multiple Boilers Sharing A Common Drain Trap
The multiple boiler condensate drain trap is Fulton Part Number 4-57-000440.
The maximum capacity to attach per condensate drain trap is 12 MM BTU/hr
total. See Figures 6 and 8.
Adhere to the following for installation:
1. The 1 inch (25.4 mm) boiler condensate drain will be connected to the
1 inch (25.4 mm) inlet on the drain trap. One or more drain lines may be
connected to this inlet (max of 12 MM BTU/hr per drain) using a common
header pipe.
2. If the water supply must be temporarily disconnected, the boilers must be
turned o to prevent accidental ue gas emission into the boiler room.
3. The condensate drain cover must be kept on at all times, except during
maintenance of the drain. This drain should be checked regularly in your
boiler maintenance schedule.
4. A condensate collecting tank and condensate pump will be required if a
oor drain is not available to collect condensate (collecting tank and pump
are not supplied with the boiler).
5. All piping (Figure 6) must be galvanized or stainless steel, and be free of
leaks. Copper, carbon steel/iron pipe, PVC or CPVC are not acceptable.
6. Connect 1 inch (25.4 mm) condensate drain(s) (at the rear of the boiler), to
the 1 inch (25.4 mm) inlet at the base of the drain tank. The header must be
at least 5.5 inches (14.2 cm) below the condensate outlet of the individual
boiler, and must remain ooded - achieved by ensuring it is at least 5.5
inches (14.2 cm) below the outlet of the condensate drain trap.
7. Connect the 1.5 inch (38.1 mm) drain outlet to an appropriate waste line
following applicable codes. The 1.5 inch (38.1 mm) drain connection on the
drain tank must be the highest point prior to going to the drain. Failure to
keep drain piping lower than this point will result in overow of the drain
tank. Slope the drain pipe away at a minimum pitch of 1 inch (25.4 mm) for
every 12 feet (3.65 m).
8. (U.S. Only) Attach a ¼” water supply to the compression tting on the oat.
The water line must be connected to an uninterruptible supply. Fulton
recommends connecting it before the “fast ll” valve to the hydronic
system, but after the back ow preventer, to avoid contamination of
a potable water supply. Maximum allowable water pressure to the
compression tting is 100 PSI (689.5 kPa).
NOTE: Ensure condensate drain piping will not be exposed to freezing
temperatures.
