LOCATING THE APPLIANCE

2.1 Locating the Appliance
The Brute 1000 and 1200's may be installed indoors
or outdoors. The unit may only be installed outdoors
in a location which will never experience freezing
temperatures. Choose a location for the unit which
allows clearances on all sides for maintenance and
inspection. See Table 1. Always install the unit on a
firm, level surface. Level the unit using the leveling
feet.
The unit 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 floors
of the structure.
When this type of location is not available, install a
suitable drain pan, adequately drained, under the
appliance.
The appliance is design-certified by CSA-
International for installation on combustible flooring;
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.
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 1 should be met when choosing the locations
for the appliance.
2.2 Correct Vent Distance from
Outside Wall or Roof Termination
The forced draft combustion air blower in the
appliance has sufficient power to vent properly when
the guidelines in Table 2 are followed.

Installations in the U.S. require exhaust vent pipe that is PVC or
CPVC complying with ANSI/ASTM D1785 F441, polypropylene
complying with ULC-S636, or stainless steel complying with
UL1738. Installations in Canada require exhaust vent pipe that is
certified 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,
stainless steel, or galvanized material.
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 (1.5 m) for each elbow used.
