Do not mount the boiler to a hollow wall. Mount to the studs only.
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.
Figure 3 - Recommended Service Clearances
This boiler must be installed upright in the vertical position as
described in this manual. DO NOT attempt to install this boiler
in any other orientation. Doing so will result in improper boiler
operation and property damage, and could result in serious
personal injury or death.
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. Locate the boiler where any leakage
from the relief valve, related piping, tank, or connections will
not result in damage to surrounding areas or lower oors of the
building. Any boiler should be installed in such a manner that if
it should leak the resulting ow of water will not cause damage
to the area in which it is installed. If the boiler is installed in
a location where a leak could cause damage, it is required to
provide containment measures. Such measures include but are
not limited to: a properly sized drain pan installed beneath the
boiler and piped to an open drain line, or installing the boiler on
a concrete oor pitched to a free owing drain. Failure to provide
containment measures is the sole responsibility of the owner and/
or installer. Leakage damages ARE NOT covered by warranty.
In addition, water leak detection devices and automatic water
shuto valves are readily available at plumbing supply houses. IT
IS HIGHLY RECOMMENDED BY THE MANUFACTURER TO INSTALL
WATER LEAK DETECTION DEVICES AND AUTOMATIC SHUTOFF
VALVES IN ANY BOILER INSTALLATION WHERE A LEAKAGE OF
WATER COULD RESULT IN PROPERTY DAMAGES.
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.
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 55 – 110 models, 300 lbs (136 kg) for 155 – 285 models, and
500 lbs (227 kg) for 399 model.
If ooding is possible, elevate the boiler to prevent oodwater 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.
