E. Wall Mounting Considerations
These boilers are wall mounted. Use only the wall mounting
instructions included in this manual.
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 250 lbs (115 kg) for 055 – 110 models, 300 lbs (136 kg) for
155 – 285 models, and 500 lbs (227 kg) for 399.
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 mounting location must be capable of carrying the weight
of the boiler and its related components. If the mounting
location cannot support a minimum of 250 lbs. (115 kg), it is
recommended to locate the boiler in a mounting location that
can support the minimum weight. Failure to comply with the
above and properly mount the boiler could result in substantial
property damage, severe personal injury, or death.
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.
F. Wall Mounting Instructions
Figure 4 - Wall Mounting Bracket - NOTE: Drawing for
Demonstration Purposes Only
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.
DO NOT use the bolts included in shipping for wall mounting
the boiler. Doing so may result in property damage, serious
injury, or death.
1. Mounting to a Wood Studded Wall
a. The building frame (studs) must be 2 X 4 minimum and 16”
on center (24” on the 399). If not, you must use ½” minimum
plywood 24” x 48” with at least fourteen (14) #12 x 3” (3/16” x
3”) round head tapping screws to the frame of the building to
provide proper support for the boiler. No alternate methods of
mounting or fastening (ex. Toggle bolts, hollow wall anchors,
or any other fastener) may be used.
b. The provided mounting bracket must be mounted directly
to the center of at least 2 studs using standard steel or stainless
steel ¼” x 2 ½” lag bolts for all models. Be sure the bracket
is level and mark the hole location of the bracket height and
horizontal stud location. Ensure the marked holes are located
in the center of the building frame (studs).
c. For all models, 2 ½” is the minimum lag bolt length if the
bracket is directly on stud. Increase lag bolt length for any
materials covering the studs.
d. Predrill pilot holes on the marked stud locations. The pilot
holes for bare studs should be 2” deep for all models. See table
below for pilot hole diameter by wood type. Increase length
for any material covering the stud. Ensure that the predrilled
holes are straight and square to the wall. Failure to do so could
lead to insufficient support or out of level boiler. See Figure 4.
NOTE:
Bolt must embed into the wood structure a minimum
of 2”.
e. Using the predrilled holes, mount the hanger bracket to the
building frame (studs) using the appropriately sized standard
steel (or stainless) lag bolt. Hang boiler on the wall mounted
bracket. Be sure that the bracket is engaged before letting
the boiler hang free. Slowly release the weight of the boiler
while ensuring that the bracket is properly secured. Verify
that the boiler is securely mounted before leaving the boiler
unsupervised.
If the boiler is not installed upright, vertically plumb, and level,
improper and unsatisfactory operation may occur, causing
excessive condensation build-up, nuisance fault codes, and
unnecessary maintenance.
Always take future maintenance into consideration when
locating the boiler. If the boiler is located in an installation
location with limited clearances, it may be necessary to remove
the boiler from the space to perform maintenance. Failure to
consider maintenance when determining installation location
could result in property damage.
All boilers eventually leak. It is recommended to install a catch
pan beneath the boiler. This catch pan should be sized with a
maximum depth of 2”, and a minimum diameter 2” greater than
the diameter of the boiler. The catch pan should empty into
an open drain line. This drain line should be 3/4” ID minimum,
piped to an open drain. Failure to follow these instructions could
result in property damage. Such damages ARE NOT covered by
product warranty.
The space must be provided with combustion / ventilation air
openings correctly sized for all other appliances located in the
same space as the boiler. 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.
