operation and service (circulator replacement, con-
trol replacement, etc.).
8. The boiler must be located where ambient room
temperatures (minimum possible temperatures
where boiler is installed assuming boiler is not in
operation and therefore contributes no heat to the
space) are always at or above 32°F to prevent
freezing of liquid condensate.

This boiler requires a dedicated direct vent system.
In a direct vent system, all air for combustion is
taken directly from outside atmosphere, and all flue
products are discharged to outside atmosphere.
Combustion air and vent pipe connections must
terminate together in the same atmospheric pres-
sure zone, either through the roof or sidewall (roof
termination preferred). See Figures 1 and 2 for re-
quired clearances.
If the concentric vent termination is being used, re-
fer to Figure 3 for proper setup.
CAUTION
Keep boiler area clean of debris and free of
flammable and combustible materials, va-
pors, and liquids.
WARNING
Failure to follow these warnings could result
in fire, property damage, personal injury, or
death.
When vent pipe is exposed to tempera-
tures below freezing, such as when it pass-
es through an unheated space or when a
chimney is used as a chaseway, vent pipe
must be insulated with ½”Armaflex or
equivalent. In extremely cold climate ar-
eas, use ¾”Armaflex or equivalent.
Combustion air must be clean outdoor
air. Combustion air must not be taken
from inside the structure because that air
is frequently contaminated by halogens,
which include fluorides, chlorides, phos-
