WARNING
!
The space must be provided with combustion / ventilation air
openings correctly sized for all other boilers 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
boilers. Failure to comply with the above warnings could result in
substantial property damage, severe personal injury, or death.

Table 6 - Minimum Installation and Service Clearances - *NOTE:
The
piping configuration of the Floor Model can be changed from the left to the
right side of the boiler.
NOTE:
For closet installations, a combustible door or removable
panel is acceptable front clearance. A 3” minimum clearance must
be provided from the boiler front cover to the removable panel or
combustible door.
NOTE:
If you do not provide the minimum clearances shown in Table
6 it might not be possible to service the boiler without removing it
from the space.
MINIMUM CLEARANCES FROM COMBUSTIBLE MATERIALS
•
Hot water pipes - at least 1” from combustible materials
•
Exhaust vent pipe - at least 1” from combustible materials
CAUTION
D. Residential Garage and Closet Installations
Precautions
If the boiler is located in a residential garage, per ANSI Z223.1:
• Mount the bottom of the boiler a minimum of 18” above the
floor of the garage to ensure the burner and ignition devices
are well off the floor.
• Locate or protect the boiler so it cannot be damaged by a
moving vehicle.
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 boilers 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.
CAUTION
WARNING
!
E. Exhaust Vent and Intake Pipe
The appliance is rated 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 appliance. Failure to vent the appliance in
accordance with the provided venting instructions will void the
warranty.
DANGER
!
Failure to vent the appliance properly will result in serious personal
injury or death.

CAUTION
Always take future maintenance into consideration when locating
the boiler. If the boiler is located in an installation location with
limited clearances, it may be necessary to remove the boiler
from the space to perform maintenance. Failure to consider
maintenance when determining installation location could result
in property damage.
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.
