Part 3 - Prepare the Boiler for Installation
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.
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.
E. Wall Mounting Instructions
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.

1. Mounting to a Concrete Wall

1. Position the upper wall mounting bracket on the concrete wall.
Ensure the bracket is level. Then use the bracket as a template to
mark four (4) drilling holes on the wall - two (2) on each side of the
bracket. See Figure 4 for details.
2. Drill and plug the wall. Then secure the upper mounting bracket
using the provided Fischer S 10x50screws. Ensure the bracket is level.
3. Install the lower mounting bracket on the boiler. Then hang the
boiler on the upper mounting bracket. Ensure the boiler is level.
Then use the lower bracket to mark the lower bracket drilling
holes.
4. Drill and plug the wall and secure the lower mounting bracket
using field provided screws. Then adjust the lower mounting
bracket on the boiler. Ensure the boiler is installed plumb. Tighten
the bracket to the boiler.

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.
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
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.
