D. Wall Mounting Considerations
These boilers are wall mounted. Use only the wall mounting
instructions included with this boiler.
Ensure the wall that the boiler is intended to be mounted on is
comprised of cement, brick, block, or wooden studs spaced 16” apart
from center. Ensure the wall is capable of supporting at least 150 lbs
(68 kgs).
If flooding is possible, elevate the boiler to prevent floodwater from
reaching the boiler.
Ensure the boiler is installed in a location that minimizes the risk of
water damage due to leaking valves, pumps, unions, etc.
The boiler may be installed on any suitable internal wall (suitable
sound-proofing may be required when installing onto a stud partition
wall).
WARNING
!
Ensure that the structure of the installation location is sufficient to
support the full installed weight of the boiler, including water content
of the heat exchanger and related piping and components. If the
mounting location cannot support a minimum of 150 lbs. (68 kg), it
is recommended to locate the boiler in a mounting location that can
support the minimum weight. Failure to ensure the structure of the
installation location is structurally sound before installation of the
boiler and properly mount the boiler can result in structural failure,
substantial property damage, severe personal injury, or death.
Do not mount the boiler to a hollow wall.
WARNING
!
The space must be provided with correctly sized combustion/
ventilation air openings for all other appliances located in the
space with the boiler. For power venting installations using room
air for combustion, refer to the boiler venting section, this manual,
for descriptions of confined and unconfined spaces. Do not install
the boiler in an attic. The boiler cover must be securely fastened
to prevent the boiler from drawing air from the boiler room. This is
particularly important if the boiler is in a room with other appliances.
Failure to comply with the above warnings could result in substantial
property damage, severe personal injury, or death.
Boiler Area Ventilation Air Openings - Closet Installations
If the boiler is installed in a closet or alcove the boiler area/room must
be ventilated.
EXCEPTION: If the boiler area/room has a volume of 150 ft
3
or greater,
ventilation of the boiler area/room is not required.
Each ventilation air opening must meet the minimum requirements
of 1 in
2
per 1000 BTU/hr., but not less than 100 in
2
. The lower ventila-
tion opening must be located within 6 in. of the floor, while the upper
opening must be located 6 in. from the top of the space.
If the boiler area has a volume less than 150 ft
3
, it is considered a
Closet or Alcove. In the US/Canada, PVC vent pipe and fittings SHALL
NOT BE USED within the closet or alcove. Only approved CPVC,
Polypropylene, or Stainless Steel vent pipe and fittings may be used.
See Table 12 for a list of approved materials. Under all circumstances
proper ventilation must be provided.
Alcove Installations
Alcove installations have the same minimum dimensions as closet
installations, except the installation must be completely open to the
room at a distance no greater than 18 in. (457 mm) from the front of
the boiler and the room must be at least three (3) times the size of the
alcove. Provided these conditions are met, the boiler requires no extra
ventilation air openings to the space. If these conditions are not met,
follow the requirements for Closet Installations.
Position the paper template on the concrete wall to locate the
positions of the hanging bracket and piping bracket.
Drill and plug the wall and secure the hanging bracket using the
screws provided (Fischer S 10x50). Ensure the hanging bracket is
level.
Secure the piping bracket on the concrete wall. Use suitable
hardware.
WARNING
!
This boiler is too heavy for one person to lift. It is highly
recommended to install the boiler with two people. Use caution
as to not drop the boiler, which could damage the boiler and
cause property damage and/or severe personal injury. Verify
that the boiler is properly and securely mounted before leaving
unsupervised. Failure to comply with the above and properly
mount the boiler could result in substantial property damage,
severe personal injury, or death.

Figure 6 - Mounting to a concrete wall
Use extreme care not to drop the boiler or cause bodily injury while
lifting or mounting the boiler onto the wall mount bracket.
Failure to follow these instructions could result in property damage,
severe personal injury, or death.
WARNING
!
This wall mounting system is not seismic rated and should not be
applied as such. Failure to comply with the above and properly
mount the boiler could result in substantial property damage,
severe personal injury, or death.
The manufacturer cannot anticipate all installation conditions. These
instructions and included parts may not apply to wall-mounting the
appliance at your installation location. The appliance must be properly
and securely mounted by a qualified installer according to installation
conditions, the technical specifications of the appliance, and to meet AHJ
/ building code requirements. All applicable permits must be obtained
before installing the appliance. Failure to follow these instructions could
result in property damage, severe personal injury, or death. Any damages
resulting from improper installation are not covered by product warranty.
