C. Leveling
In order for the condensate to properly flow out of the collection
system, the area where you locate the boiler must be level. Location
must also fully support the weight of the filled boiler.
Figure 1 - Correct and Incorrect Leveling
Ensure that the floor and structure of the installation location are
sufficient to support the full installed weight of the boiler, including
water content of the heat exchanger and related piping. Failure
to ensure the floor and structure of the installation location are
structurally sound before installation of the boiler can result in
structural failure, substantial property damage, severe personal
injury, or death.
This boiler is approved for installation on combustible flooring,
but must never be installed on carpeting. Installing this boiler on
carpeting could result in fire, property damage, severe personal
injury, or death.

D. Clearances for Service Access
NOTE:
If you do not provide the minimum clearances shown in Figure
2 it might not be possible to service the boiler without removing it
from the space.
Figure 2 - Recommended Service Clearances
All boilers eventually leak. It is recommended to install a catch
pan beneath the boiler. This catch pan should be sized with a
maximum depth of 2”, and a minimum diameter 2” greater than
the diameter of the boiler. The catch pan should empty into an
open drain line. This drain line should be 3/4” ID minimum, piped
to an open drain. Failure to follow these instructions could result
in property damage. Such damages ARE NOT covered by product
warranty.
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.
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.
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.
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.
NOTE:
A combustible door or removable panel is acceptable front
clearance.
Minimum Clearances from Combustible Materials
•
Hot water pipes - at least 1” from combustible materials
•
Exhaust vent pipe - at least 1” from combustible materials
