Figure 2 - Correct and Incorrect Leveling
The space must be provided with combustion / ventilation
air openings correctly sized for all other appliances located in
the same space as the boiler. The boiler cover must be securely
fastened to prevent the boiler from drawing air from the boiler
room. This is particularly important if the boiler is in a room with
other appliances. Failure to comply with the above warnings could
result in substantial property damage, severe personal injury, or
death.
All boilers eventually leak. 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. Any boiler should be installed in such a manner that if
it should leak the resulting flow of water will not cause damage
to the area in which it is installed. If the boiler is installed in
a location where a leak could cause damage, it is required to
provide containment measures. Such measures include but are
not limited to: a properly sized drain pan installed beneath the
boiler and piped to an open drain line, or installing the boiler on
a concrete floor pitched to a free flowing drain. Failure to provide
containment measures is the sole responsibility of the owner and/
or installer. Leakage damages ARE NOT covered by warranty.
In addition, water leak detection devices and automatic water
shutoff valves are readily available at plumbing supply houses. IT
IS HIGHLY RECOMMENDED BY THE MANUFACTURER TO INSTALL
WATER LEAK DETECTION DEVICES AND AUTOMATIC SHUTOFF
VALVES IN ANY BOILER INSTALLATION WHERE A LEAKAGE OF
WATER COULD RESULT IN PROPERTY DAMAGES.
Precautions
If the boiler is located in a residential garage, per ANSI Z223.1:
• Install the boiler burner and ignition devices a minimum of 18”
above the floor of the garage. This will ensure the burner and
ignition devices are well off the floor.
• When raising the boiler ensure the entire bottom and fully
filled weight of the boiler are fully supported.
• Locate or protect the boiler so it cannot be damaged by a
moving vehicle.
Figure 3 - Recommended Service Clearances
F. Exhaust Vent and Intake Pipe
The boiler is rated ANSI Z21.13 Category IV (pressurized vent, likely
to form condensate in the vent) and requires a special vent system
designed for pressurized venting.
NOTE: The venting options described here (and further detailed
in the Venting section, this manual) are the lone venting options
approved for this boiler. Failure to vent the boiler in accordance
with the provided venting instructions will void the warranty.
E. Residential Garage and Closet Installations
Check with your local Authority Having Jurisdiction for requirements
when installing the boiler in a garage or closet. 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.
The space must be provided with correctly sized combustion/
ventilation air openings for all other appliances located in the
space with the boiler. For power venting installations using room
air for combustion, refer to the venting section, this manual, for
descriptions of confined and unconfined spaces. Do not install the
boiler in an attic. Failure to comply with these warnings could result
in substantial property damage, severe personal injury, or death.
Failure to vent the boiler properly will result in serious personal
injury or death.
Do not attempt to vent this boiler by any means other than those
described in this manual. Doing so will void the warranty and may
result in severe personal injury or death.
