Part 3 - Prepare the Boiler
Remove all sides of the shipping crate to allow the boiler to be
moved into its installation location. The boiler is also equipped
with leveling feet that can be used to level the boiler properly on
an uneven location surface. If surface flooring is rough, take care
when moving the boiler into position, as catching the leveling
feet could damage the boiler.
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 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
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
and 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

This boiler has a condensate disposal system that may
freeze if exposed to sustained temperatures below 32
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.
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.
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.
High heat sources (generating heat 100
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.
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.
Failure of the boiler or components due to incorrect operating

conditions IS NOT covered by product warranty.
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
