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
o
F / 37
o
C or greater,
such 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.
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
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 a drain pan.
Leakage damages ARE NOT covered by warranty.
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.
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.
Failure to follow these instructions could result in property
damage, severe personal injury, or death.
Assure that the structure of the installation location is sufficient
to support the full installed weight of the boiler, including water
content of the heat exchanger and related piping. Failure to
ensure the structure of the installation location is structurally
sound before installation of the boiler can result in structural
failure, substantial property damage, severe personal injury, or
death.

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.
Minimum Clearances from Combustible Materials
• Hot water pipes - at least 1” from combustible materials
• Exhaust vent pipe - at least 1” from combustible materials
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.
