• Condensate Removal Pump (Part # 554200)
• 2" Mesh Vent Screens (Part # 7850P-088)
NOTE: When using an optional system sensor, pipe insulation
must be wrapped around it to improve temperature measurement
accuracy and increase overall system efficiency.

Part 3 - Prepare the Boiler Installation

Remove all sides of the shipping crate to allow the boiler to be
moved into its installation location.
CAUTION
COLD WEATHER HANDLING - If the boiler has been stored in a
very cold location (BELOW 0
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 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.
Do not use this boiler only for space heating applications.
Circulators suitable for DHW applications must be used.
Failure to take precautions could result in property damage,
severe personal injury, or death.

F. Precautions
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.
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.
!
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
• Location that could cause the system and boiler to freeze and
leak
• Incorrectly sized expansion tank
6. Clean and flush system when reinstalling an boiler.
Do not introduce toxic chemicals, such as antifreeze or boiler
treatments, into any piping meant for potable water purposes.
Do not connect the boiler DHW connections to any heating systems
o
C and
or components that have been previously used for non-potable
applications.
Ensure that all piping and components connected to the boiler are
suitable for potable water applications.
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.
B. Leveling
o
F
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.
C. Clearances for Service Access
See Table 6 for recommended service clearances. If these minimum
clearances are not provided, it may not be possible to service the boiler
without removing it from the space.
