Read before proceeding
The vent piping operates with positive pressure
. Th e vent
piping must be completely sealed and securely supported.
Use only the vent components listed in this manual
. Use
of any other materials could result in vent system failure.
Exposed vent pipe poses a potential burn hazard to people and
pets. Insulate or shield the pipe where necessary to prevent risk.
Never drill through, or install screws into
, the vent pipe or
vent components.
Seal test hole with high temperature silicone aft er each
combustion test and annual inspection to prevent gases and
condensation from leaking during appliance operation.
Failure to properly install the vent piping could result in fl ue
gas leakage, causing possible severe personal injury, death or
substantial property damage.
Code compliance
— Follow all applicable local codes when
installing the vent system. Where codes diff er from this
manual, follow code requirements. Contact Hydrotherm if you
have any questions regarding the installation.
Terminate the vent and air piping following the guidelines
in this manual. Avoid vent termination locations likely to be
aff ected by winds, snowdrift s, people and pets. Protect building
materials and vegetation from degradation caused by the fl ue
gases and condensation.

❑
Th e vent connection at the boiler is for Heat-Fab EZ-Seal vent piping only.
EZ-Seal vent att achment
Insert EZ-Seal pipe male end into the boiler connection
(Do not cover
combustion test port)
. Make sure the locking tabs slide under the EZ-Seal
locking ring. Bend back locking tabs to complete the joint. Follow EZ-Seal
instructions to complete the vent piping installation.
Th e concentric vent/air termination must be done only with Saf-T Vent type SC
vent components. Th is requires that all of the vent piping be Saf-T Vent EZ-Seal for
compatibility. DO NOT apply this vent/air termination option using any other
vent materials.
