Section 2 -
LOCATING THE APPLIANCE
2.1 GeneralInformation
The Brute unit is designed for indoor installations only.
The appliance should be located to provide clearances on all
sides for maintenance and inspection. It should not be located
in an area where leakage of any connections will result in
damage to the area adjacent to the appliance or to lower oors
of the structure.
When such a location is not available, it is recommended that
a suitable drain pan, adequately drained, be installed under the
appliance.
The appliance is design certied by CSA-International for
installation on combustible ooring; in basements; in closets,
utility rooms or alcoves. Brute Boilers must never be
installed on carpeting. The location for the appliance should
be chosen with regard to the vent pipe lengths and external
plumbing and on a level surface. The unit shall be installed
such that the gas ignition system components are protected
from water (dripping, spraying, rain, etc.) during operation
and service (circulator replacement, control replacement, etc.).
When vented vertically, the Brute must be located as close as
practical to the vertical section of the vent. If the vent terminal
and/or combustion air terminal terminate through a wall, and
there is potential for snow accumulation in the local area, both
terminals should be installed at an appropriate level above
grade or the maximum expected snow line.
The dimensions and requirements that are shown in Table 4
should be met when choosing the locations for the appliance.

The forced draft combustion air blower in the appliance has
sufcient power to vent properly when the guidelines in Table
2are followed.
NOTE: When located on the same wall, the Brute
combustion air intake terminal must be installed a
minimum of 12” below the exhaust terminal. Models
399-850 (commercial models) also require a minimum
horizontal distance from intake to exhaust terminal of 36”.
For concentric vent terminal kit (optional), follow installation
instructions included with the kit.

Combustion Intake and Vent must be the same size.
Installations in the U.S. require exhaust vent pipe that is a combination
of PVC & CPVC complying with ANSI/ASTM D1785 F441 or stainless
steel complying with the stainless steel vent suppliers listed in Section 3.
Installations in Canada require exhaust vent pipe that is certied to
ULC S636.
Intake (air) pipe must be PVC or CPVC that complies with ANSI/ASTM
D1785 F441, ABS that complies with ANSI/ASTM D1527 or galvanized
material.
The installer must comply fully with the manufacturer’s installation
instructions, including use of minimum exhaust length CPVC, to main-
tain ANSI Z21.13 safety certication.
Closet and alcove installations do not allow the use of PVC under any
circumstances
To calculate max equivalent length, measure the linear feet of the pipe,
and add 5 feet (1.5m) for each 90° elbow used. Add 2 1/2 feet (.76
meters) for each 45 elbow used.
