1.J Locating the Unit
This unit may be installed indoors or outdoors. If installing
outdoors in a location that may experience freezing
temperatures, precautions must be taken to prevent water
in the heat exchanger and condensate inside and outside
of the boiler from freezing. Damage due to freezing water
or condensate is not covered by the warranty.
Choose a location for the unit which allows clearances on
all sides for maintenance and inspection. See Table 3.
Always install the unit on a rm, level surface. The unit
must be installed on a 4” equipment pad or suitable
blocking so that there is elevation for the condensate trap
and condensate neutralizer (not included). See Figure 16
on page 36 for pad dimensions and condensate trap
position.
The unit should not be located in an area where leakage
of any connections will result in damage to the area
adjacent to the unit, or to lower oors of the structure.
When this type of location is not available, install a
suitable drain pan, adequately drained, under the unit.
This unit is design-certied by CSA-International for
installation on combustible ooring; in basements;
in utility rooms or alcoves. Boilers must never be
installed on carpeting. The location for the unit 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 unit 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 3 must be met when choosing the location for the
unit.
Ensure the location takes into account the maximum
allowable vent length shown in SECTION 2 of this
manual.
NOTE : 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.).
