Part 3 - Prepare the Boiler
COLD WEATHER HANDLING - If the boiler has been stored in a
very cold location (BELOW 0
o
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.
Remove all sides of the shipping crate, and the wooden block
that holds the boiler in place during shipping. Slide the boiler
from the mounting bracket, which is axed to the skid (Figure 1
and 2). Remove the mounting bracket from the crate (Figure 1).
Take care to place the boiler in a safe location prior to installation
to prevent damage to the mechanical connections.
• Vision II (7250P-322)
NOTE: When using an optional system sensor, pipe insulation
must be wrapped around it to improve temperature
measurement accuracy and increase overall system eciency.
This boiler has a condensate disposal system that may
freeze if exposed to sustained temperatures below 32
o
F.
Precautions should be taken to protect the condensate trap
and drain lines from sustained freezing conditions. Failure
to take precautions could result in property damage, severe
personal injury, or death.

This boiler is certied 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.
A. Locating the Boiler
1. Installation Area (Mechanical Room) Operating Conditions
• Ensure ambient temperatures are higher than 32
o
F /
0
o
C and lower than 104
o
F / 40
o
C
• 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
o
F
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.
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 ammable 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.
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 inuenced 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.
