Prevent the air from becoming contaminated by the products, places, and conditions listed in this manual.
Avoid continuously high levels of humidity
Never close existing ventilation openings
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 the heat exchanger and other 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.
This boiler is certified for indoor installations only. Do not install the boiler outdoors. Failure to install this boiler indoors could result in
substantial property damage, severe personal injury, or death.
This boiler must be installed as described in this manual: upright, with the vent adapters in the vertical position. 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.
2. Check for nearby connections to:
System water piping
Venting connections
Gas supply piping
Electrical power
Condensate drain
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. The boiler should be located near a floor drain, or installed in an adequately drained drain pan.
Westinghouse WILL NOT be held liable for leakage damages.
To conserve water and energy, insulate all water piping, especially the hot and recirculation water lines.
3. Check area around boiler. Remove any combustible materials, gasoline, and other flammable liquids.
Failure to keep boiler area clear and free of combustible materials, liquids, and vapors can result in substantial property damage,
severe personal injury, or death.
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 an boiler.
NOTE:
When installing in a zero clearance location, it may not be possible to read or view some product labeling. It is recommended to
make note of the boiler model and serial number.
C. LEVELING
In order for the condensate to properly flow out of the collection system, the boiler must be installed level. Failure to ensure the boiler is
installed level will result in improper boiler operation.
