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.
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.
A. Locating the Boiler
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
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
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.
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.
High heat sources (generating heat 100
o
F / 37
o
C or greater, 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.
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
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.
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.
Do not mount the boiler to a hollow wall. Mount to the studs only.
6. Clean and flush system when reinstalling a boiler.
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.
Use extreme care not to drop the boiler or cause bodily injury while
lifting or mounting the boiler onto the optional wall mount bracket.
Gas conversion should be performed BEFORE the boiler is installed.
Carefully follow the gas conversion instructions when performing
the conversion.
Failure to follow these instructions could result in property damage,
severe personal injury, or death.
