6B.2 Piping Requirements
Water piping should be supported by suitable
hangers and floor stands. Do not support piping with the
appliance. Due to expansion and contraction of copper
pipe, consideration should be given to the type of
hangers and supports used. Rigid hangers may transmit
noise through the system resulting from piping sliding
in the hangers. It is recommended that padding be used
when rigid hangers are installed. Maintain 1" (2.5cm)
clearance to combustibles for hot water pipes.
Pipe the discharge of the relief valve (full size) to
the drain or in a manner to prevent injury in the event of
pressure relief. Install a diaphragm-type expansion tank,
flow check, and shutoff valves where needed or as
required by code.
Brute Elite 80-500 can be ordered with pumps.
Whether the factory pumps or other pumps are installed
the piping should be installed such that the pump
supplies flow to the heater it is attached to only. The
factory pumps are sized for 30 feet and 6 elbows of total
pipe length, so the heater should be placed within 15
feet of the tank. If longer runs are required, properly-
sized field-supplied pumps should be used.
SECTION 6B.
Water Connections -
BNTV Water Heater
Section 6 is divided into two parts. The first is
for BNTH models and is Section 6A. The
second is for BNTV models and is Section 6B.
Refer to the proper section for instructions in
installing and piping your product. Refer to
Table 9 for pipe sizes required.
6B.1 BNTV Water Quality
BNTV water heaters must be installed in water
conditions of 10gpg hardness or less with a pH range of
8.2 to 9.5. Operating the BNTV in water with higher
hardness levels will cause heat exchanger fouling,
erosion, or corrosion leading to premature component
failure, reduced efficiency, heat exchanger failure or
system failure. Failure of this type will not be
warranted. If the water in use exceeds the conditions
recommended water softeners or other devices should
be installed to improve water quality.

NOTES:
1. Optional CWMU & Recirc. line location.
2. Locate BNTV DHW sensor or remote aquastat well
in lower 1/3 of tank.
3. Back flow preventer may be required - check local codes.
4. Thermal expansion tank may be required - check local codes.
5. Factory mounted pumps are sized for a max pipe length of
30' total, 6-90° elbows, full pipe size.
6. Caution: Pump sizing must be based opon water hardness at job site.
