BOILERS AND VOLUME WATER HEATERS
tank, flow check, and shutoff valves where needed or as
required by code.
Brute 150-500 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, a properly-sized field-supplied
pump should be used.
6B.3 Cold Water Make-Up
The cold water make-up may be connected to the tank
or to the inlet of the boiler as shown in Figures 22-
25. Install back flow preventers and shut offs where
needed or required by code. Pipe sizes may have to be
increased to accomodate cold water make-up flow.
6A.4 Condensate Drain
A condensate drain trap is built into the Brute unit.
Connect a 3/4" PVC pipe between the drain connection
and a floor drain (or a condensate pump if a floor drain
is not accessible).
The condensate drain must be installed so as to prevent
accumulation of condensate. When a condensate
pump is not used, the tubing must continuously slope
downward toward the drain with no spiraling.
Consult local codes for the proper disposal method for
the condensate.
Condensate is mildly acidic (pH = 5), and may harm
some floor drains and/or pipes, particularly those
that are metal. Ensure that the drain, drainpipe,
and anything that will come in contact with the
condensate can withstand the acidity, or neutralize
the condensate before disposal. Damage caused by
Caution
failure to install a neutralizer kit or to adequately
treat condensate will not be the manufacturer's
responsibility.
6B.5 Freeze Protection
Brute heaters are not certified for outdoor installation, so
the chance of freezing is minimized. In an event such as
power outage, component failure or other issue when
freezing is likely, the heater and system must be drained
to avoid the risk of damage due to freezing. Glycol must
not be used in volume water heating applications.
6B.6 BNTV Suggested Piping Schematics
Figures 23-25 show suggested piping configurations
for BNTV boilers. These diagrams are only meant as
guides. All components or piping required by local code
must be installed.
6B.7 BNTV Suggested Pumps
Possible pumps for BNTV sizes 600-850 are Grundfos
model TP 40-160/2B, or for size 600 (only) is Armstrong
model E22B. See Table 8 on page 16 for heater water
flow and head requirements.
Note - The head loss for the piping, fittings, and
accessories must be calculated and added to the heater
