Failure to keep the boiler area clear and free of combustible materials,
liquids, and vapors can result in substantial property damage, severe
personal injury, or death.
The service life of the boiler's exposed metallic surfaces, such as
the casing, as well as internal surfaces, such as the heat exchanger,
are directly influenced by proximity to damp and salty marine
environments. In such areas higher concentration levels of
chlorides from sea spray coupled with relative humidity can lead to
degradation of boiler components. In these environments, boilers
must not be installed using direct vent systems which draw outdoor
air for combustion. Such boilers must be installed using room air for
combustion. Indoor air will have a much lower relative humidity, and
hence potential corrosion will be minimized.
High heat sources (generating heat 100
as boiler flue pipes, space heaters, etc.) may damage plastic
components of the boiler as well as plastic vent pipe materials. Such
damages ARE NOT covered by warranty. It is recommended to keep
a minimum clearance of 8" from high heat sources. Observe heat
source manufacturer instructions, as well as local, state, provincial,
and national codes, laws, regulations, and ordinances when installing
this boiler and related components near high heat sources.
Failure of the boiler or components due to incorrect operating
conditions IS NOT covered by product warranty.
4. Gas control system components must be protected from dripping
water during operation and service.
5. If the boiler is to replace an existing boiler, check for and correct any
existing system problems, such as:
•
System leaks
•
Location that could cause the system and boiler to freeze and
leak
•
Incorrectly sized expansion tank
6. Clean and flush system when reinstalling a boiler.
NOTE: This boiler must be installed within the prescribed clearances.
If local building codes require additional clearance, these codes
supersede Westinghouse's. It is recommended to make note of the
boiler model and serial number before finalizing installation.
The boiler is extremely heavy. Use extreme care not to drop the boiler
or cause bodily injury while lifting. Failure to follow these instructions
could result in property damage, severe personal injury, or death.
Gas conversion should be performed BEFORE the boiler is installed.
Carefully follow the gas conversion instructions when performing
the conversion. Failure to follow these instructions could result in
property damage, severe personal injury, or death.
B. Flooring
Assure that the floor and structure of the installation location are
sufficient to support the full installed weight of the boiler, including
water content of the heat exchanger and related piping. Failure
to ensure the floor and structure of the installation location are
structurally sound before installation of the boiler can result in
structural failure, substantial property damage, severe personal
injury, or death.

C or greater, such
This boiler is approved for installation on combustible flooring,
but must never be installed on carpeting. Installing this boiler on
carpeting could result in fire, property damage, severe personal
injury, or death.
C. Leveling
In order for the condensate to properly flow out of the collection
system, the area where you locate the boiler must be level.
Location must also fully support the weight of the filled boiler.
NOTE: It is recommended that the boiler be installed on a 4 - 6"
raised boiler pad rated for the weight of the fully operational boiler
and related piping. If flooding is a concern, it is recommended to
further elevate the boiler pad to prevent water from reaching the
boiler.
D. Clearances for Service Access
NOTE: If you do not provide the minimum clearances shown in
Figure 2 it might not be possible to service the boiler without
removing it from the space.
NOTE: A combustible door or removable panel is acceptable front
clearance.
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.
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 floors of the
building. Any boiler should be installed in such a manner that if
it should leak the resulting flow 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 floor pitched to a free flowing 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
shutoff 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.
