LOCATING THE APPLIANCE
2.1 Locating the Appliance
The 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 1. Always install the unit on a
¿UPOHYHOVXUIDFH,WLVUHFRPPHQGHGWKDWWKHXQLWLV
installed on a raised 4” pad so that there is elevation for
a condensate neutralizer kit (not included with unit).
The unit should not be located in an area where
leakage of any connections will result in damage to
WKHDUHDDGMDFHQWWRWKHDSSOLDQFHRUWRORZHUÀRRUV
of the structure.
When this type of location is not available, install a
suitable drain pan, adequately drained, under the
appliance.

. 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 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 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
DSSOLDQFHKDVVXI¿FLHQWSRZHUWRYHQWSURSHUO\ZKHQ
the guidelines in Table 2 are followed.
Note - When located on the same wall, the Unit
combustion air intake terminal must be installed a
minimum of 12” (
30cm)
below the exhaust terminal.
There must also be a minimum horizontal distance
from intake to the exhaust terminal
of 84” (
213cm)

Combustion Intake and Vent must be the same size.
Installations in the U.S. require exhaust vent pipe that is 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

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.
To calculate max equivalent length, measure the linear feet of
the pipe, and add 5 feet
(1.5 m) for each elbow used.
