with other vent systems or unlisted pipe ttings. Plastic components
and specied primers and glues of the certied vent system must be
from a single system manufacturer and not intermixed with other system
manufacturer’s vent system parts. For installation in Canada, eld
supplied plastic vent piping must comply with CAN/CSA B149.1 (latest
edition) and be certied by the local jurisdiction.

For specic venting components (terminals, ttings), contact the
respective vent manufacturer.
SSB boilers are equipped with a ue/condensate pressure switch on each
module, able to switch off the burner in case of vent or condensate blockage.

WARNING: Do not attempt to restart the boiler in case of
vent or condensate blockage, contact a qualied contractor.
Failure to comply with this WARNING could result in the
accumulation of carbon monoxide gas which can cause
severe personal injury or death.

DANGER: It is extremely important to follow these venting
instructions carefully. Failure to do so will cause severe
personal injury, death or substantial property damage.


DANGER: Use of cellular core PVC (ASTM F891), cellular
core CPVC or Radel® (polyphenosulfone) in venting
systems is prohibited.

DANGER: Covering non-metallic vent pipe and ttings with
thermal insulation is prohibited. Failure to do so will cause
severe personal injury, death or substantial property damage.

WARNING: Do not connect this gas appliance with any other
appliance unless approved by manufacturer. Failure to comply
with this WARNING could result in the accumulation of carbon
