3. Check area around boiler. Remove any combustible materials,
gasoline, and other flammable liquids.
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: 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.

Figure 1 - Lifting the Boiler
Use extreme care not to drop the boiler or cause bodily injury
while lifting the boiler.
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
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.
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. 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.
D. Clearances for Service Access
NOTE: If you do not provide the minimum clearances shown in
Figure 3 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.
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.
