Part 3 - Prepare the Boiler for Installation

CAUTION
COLD WEATHER HANDLING - If the boiler has been stored in a very
cold location (BELOW 0oF) 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 32oF. Precautions 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.

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

F
to perform maintenance. Failure to consider maintenance when
determining installation location could result in 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.
