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
number.
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.
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.
Failure of the boiler or components due to incorrect operating
conditions IS NOT covered by product warranty.
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.
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.
Figure 2 - Correct and Incorrect Leveling
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.
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.
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.
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.
B. Flooring
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.
