Part 3 - Prepare the Boiler for Installation

CAUTION
COLD WEATHER HANDLING - If the boiler has been stored in a very
o
cold location (BELOW 0 F) before installation, handle with care
until the components come to room temperature. Failure to do so
could result in damage to the boiler.
Carefully consider installation when determining boiler location.
Please read the entire manual before attempting installation.
Failure to properly take factors such as boiler venting, piping,
condensate removal, and wiring into account before installation
could result in wasted time, money, and possible property damage
and personal injury.
A. Locating the Boiler
WARNING
This boiler is certified for indoor use only. DO NOT INSTALL
OUTDOORS. Outdoor installations ARE NOT covered by warranty.
Failure to install the boiler indoors could result in property damage,
severe personal injury, or death.
Incorrect ambient conditions can lead to damage to the heating
system and put safe operation at risk. Ensure that the installation
location adheres to the information included in this manual. Failure
to do so could result in property damage, serious personal injury,
or death. Failure of boiler or components due to incorrect operating
conditions IS NOT covered by product warranty.
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.
1. Installation Area (Mechanical Room) Operating Conditions
• Ensure ambient temperatures are higher than 32
o o
lower than 104 F / 40
• 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
• Ensure a minimum 1" clearance around hot water and exhaust
vent pipes
• NOTE: To prevent condensing in the fan, it is recommended to
avoid prolonged exposure to temperatures below 45
WARNING
This boiler has a condensate disposal system that may freeze
if exposed to sustained temperatures below 32
should be taken to protect the condensate trap and drain lines
from sustained freezing conditions.
Circulators suitable for DHW applications must be used.
Failure to take precautions could result in property damage, severe
personal injury, or death.

F. Precautions
CAUTION
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.
2. Check for nearby connections to:
• System water piping
• Venting connections
• Gas supply piping
• Electrical power
• Condensate drain
3. Check area around boiler. Remove any combustible materials,
gasoline, and other flammable liquids.
WARNING
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.
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
o
C and
• Location that could cause the system and boiler to freeze and
leak
• Incorrectly sized expansion tank
CAUTION
Always take future maintenance into consideration when locating
the boiler. If the boiler is located in an installation location with
limited clearances, it may be necessary to remove the boiler
from the space to perform maintenance. Failure to consider
maintenance when determining installation location could result in

F
property damage.
6. Clean and flush system when reinstalling a boiler.
WARNING
Do not introduce toxic chemicals, such as antifreeze or appliance
treatments, into any piping meant for potable water purposes.
Do not connect DHW connections to any heating systems or
components that have been previously used for nonpotable
applications.
Ensure that all piping and components connected to the appliance
are suitable for potable water applications.
Failure to follow these instructions could result in serious personal
injury or death.
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.
