6.5 Recognized Chemicals
The following manufacturers offer glycols,
inhibitors, and anti-foamants that are suitable for use
in the Brute Elite. Please refer to the manufacturers
instructions for proper selection and application.
1. Sentinel Performance Solutions Group
2. Hercules Chemical Company
3. Dow Chemical Company
6.6 Hot Water Piping
6.6.1 Domestic Hot Water Piping (BLMC)
Connect domestic hot and cold water piping to the
boiler at locations noted in Figure 13 . Expected DHW
performance is indicated in Table 8 .
Use of flow restrictor is optional to prevent colder
water at excessive flow rates. Contact Bradford White
for alternate configurations.
6.6.2 Indirect Water Heater Piping (BLMH)
The BLMH model can control an indirect water
heater zone. Pipe to the locations shown in Figure 13 .
Zone valve and associated wiring are not required.
Setpoint is made via aquastat located on the indirect
water heater, or can be controlled at the boiler via a
remote sensor.
6.7 Condensate Drain
A condensate drain trap is built into the Brute Elite.
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 disposal method.
Caution
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
failure to install a neutralizer kit or to adequately
treat condensate will not be the manufacturer’s
responsibility.
