(continued)
Ultra Boilers must be vented and supplied
with combustion and ventilation air using
piping and methods described in this

.
Every boiler must have its own vent. DO
NOT
common vent with any other appliance.
See page16.
Inspect nished vent and air piping thoroughly
to ensure all are airtight and comply with the

Venting/combustion air piping - Installations
must provide provisions for combustion and
ventilation air in accordance with the sec-
tion “Air for Combustion and Ventilation,” of
the National Fuel Gas Code - ANSI Z223.1/
NFPA54 – latest edition, or Sections 8.2, 8.3,
or 8.4 of Natural Gas and Propane Installation
Code - CAN/CSA B149.1, or applicable provi-
sions of the local building codes.
Use only the materials listed in this manual for
vent and air pipe and ttings. Failure to comply
could result in severe personal injury, death or
substantial property damage.
If used, a masonry chimney can ONLY be
used as a PIPE CHASE for vent and air pipes
— e vent and air piping must be installed as
instructed in this manual and all joints must be
sealed. e chimney must be used only for Ul-
tra boilers. NO OTHER appliance or replace
can be connected to the chimney.
e chimney must be straight, with no osets,
and the vent and air piping materials must
comply with this instruction manual.
e chimney must be tted with a sealed ac-
cess opening, through which the interior of the
chimney can be inspected.
e chimney and liner must be inspected at

Failure to comply could result in severe personal
injury, death or substantial property damage.
1. Combustion air must be piped from outside to the boiler, fol-
lowing the instructions in this manual, and compliant with
all applicable codes. Read the warning in Figure11,page16,
and ensure the air intake will not be likely to draw in con-
taminated air.
2. Combustion air can be piped individually for each boiler, or
it can be manifolded as shown in Figure59,page59. Air pip-
ing must always terminate on the same side (or roof ) of the
building as the vent.
1. Boiler ue gases must be piped from the boiler to outside, fol-
lowing the instructions in this manual, and compliant with all
applicable codes. e vent pipe must terminate either through
the sidewall or through the roof, located with the correct
separation from the air termination. See Figure14,page20,
and the associated instructions referenced.
2. Each Ultra boiler requires a separate vent. Do not common
vent.
