Brute Deluxe (500-2000)
through 13. These diagrams are meant only as a guide.
Components required by local codes must be properly
installed.
The minimum inlet water temperature for the Brute
Deluxe is 120°F (49°C) to avoid condensing on the
copper coils.
4B.2 Hot Water Supply Piping —
Water Heater
Follow the tank manufacturer’s guidelines for
completion of the hot water system connections.
NOTE: A listed temperature and pressure relief valve
listed as complying with the Standard for Relief
Valves and Automatic Gas Shutoff Devices for Hot
Water Supply Systems (ANSI Z21.22 / CSA 4.4) of
suitable discharge capacity must be installed in the
separate storage tank system.
If the Brute Deluxe water heater is installed in a
closed water supply system, such as one having a
backflow preventer in the cold water supply line, the
relief valve may discharge periodically, due to thermal
expansion. Means (such as a properly-sized expansion
tank) shall be provided to control thermal expansion.
Contact the water supplier or local plumbing inspector
on how to control this situation.
4B.3 Water Flow Requirements —
Water Heater
In a water heating application (an open system),
new water is constantly being introduced. With the new
water comes a fresh supply of minerals that can be
deposited on the unit’s heat exchanger. This is
commonly known as scaling. The amount of minerals
will depend upon the hardness of the water. Water can
also be aggressive, and can erode metals, including
copper, if the water is moved too quickly. The water
flow requirements for the Brute Deluxe water heater are
based upon the hardness of the water. The water flow is
kept high enough to prevent scaling, but low enough to
prevent tube erosion. For extremely soft or hard water,
cupro-nickel tubes are available. Contact a
Representative if you have questions or concerns about
water quality.
Pump-mounted water heaters can be ordered with
standard pumps for soft or normal water or with pumps
for hard water. The pumps used are sized for the
headloss through the heater, plus 30 feet (9.1m) of full-
sized piping (same size as heater outlet) and a normal
number of fittings.
Table 9 specifies water flow rates for water
heaters, which will enable the user to size a pump. The
headloss shown is for the heater only, and the user will
need to add the headloss of the piping system to
properly size the pump.
4B.4 Combined Water Heating (potable)
and Space Heating — Water Heater
NOTE: These systems are not allowed in the
Commonwealth of Massachusetts.
Piping and components connected to this water
heater for the space heating application shall be suitable
for use with potable water.
Toxic chemicals, such as used for boiler treatment,
shall not be introduced into the potable water used for
space heating.
This water heater when used to supply potable
water shall not be connected to any heating system or
component(s) previously used with a non-potable water
heating appliance.
When the system requires water for heating at
temperatures higher than required for other uses, an
anti-scald mixing or tempering valve shall be
installed to temper the water for those uses in order
to reduce scald hazard potential.
4B.5 Freeze Protection – Water Heater
Although Brute Deluxe water heaters are design-
certified for outdoor installations, such installations are
not recommended in areas subject to freezing
temperatures, unless proper precautions are taken.
Power outage, interruption of gas supply, failure of
system components, activation of safety devices, etc., may
prevent a heater from firing. Any time a heater is sub-
jected to freezing conditions, and the heater is not able
to fire, and/or the water is not able to circulate, there is
a risk of freezing in the heater or in the pipes in the
system. When water freezes, it expands. This can result in
bursting of pipes in the system, or damage to the heater,
which could result in leaking or flooding conditions.
Contact the local factory representative or for
additional information.
SECTION 5.
Electrical Connections
WARNING
The appliance must be electrically grounded in
accordance with the requirements of the authority
having jurisdiction or, in the absence of such
requirements, with the latest edition of the National
Electrical Code, ANSI/NFPA 70, in the U.S. and with
latest edition of CSA C22.1 Canadian Electrical Code,
Part 1, in Canada. Do not rely on the gas or water
piping to ground the metal parts of the boiler. Plastic
pipe or dielectric unions may isolate the boiler
electrically. Service and maintenance personnel, who
work on or around the boiler, may be standing on wet
floors and could be electrocuted by an ungrounded
boiler.
Single pole switches, including those of safety
controls and protective devices must not be wired in a
grounded line.
All electrical connections are made in the field
