Due to the extreme flammability of most glues, cements, solvents, and primers used to join plastic exhaust vent and intake pipes,
explosive solvent vapors must be cleared from all vent piping before start-up. Avoid using excess cement or primer, as this may pool in
the vent pipes. Vent assemblies should be allowed to cure for a period of at least 8 hours before powering a connected appliance.
Failure to follow these instructions will result in substantial property damage, severe personal injury, or death. It is the
installers’
responsibility to understand the hazards associated with explosive solvents and take the necessary precautions to avoid these risks.


The exhaust and intake components installed with this boiler must be used for near boiler piping BEFORE transitioning to the
approved materials listed above. DO NOT REMOVE these installed components. Doing so WILL VOID appliance warranty.

PVC/CPVC pipe and fittings of the same diameter are considered interchangeable.

Do NOT use Foam Core Pipe in any portion of the exhaust piping from this boiler.

DO NOT connect PVC/CPVC to PP without an approved vent connector.

When installing AL29-4C vent piping, install a PVC-to-stainless adapter at the boiler vent connection, and at the termination
when using an HTP PVC termination kit. DO NOT mix AL-29-4C piping from different manufacturers unless using adapters
specifically designed for the purpose by the manufacturer.

*PVC-DWV for air intake applications ONLY.
Failure to follow these directions will result in substantial property damage, severe personal injury, or death.
Table 9
– Approved Materials for Exhaust Vent and Intake Pipe
Exhaust vent and intake adaptors are not designed as load-bearing devices, and must not be used to support exhaust vent and intake
piping. All vent pipes must be glued, properly supported, and the ex
haust must be pitched a minimum of ¼” per foot back to the boiler
to allow drainage of condensate. Failure to properly support vent piping and follow the information in this statement could result in
product damage, severe personal injury, or death.
NOTE: The use of double-wall vent or insulated material for the combustion air inlet
pipe is recommended in cold climates to prevent the condensation of airborne
moisture in the incoming combustion air.
High heat sources (sources generating heat 100
o
F / 37
o
C or greater, such as stove
pipes, space heaters, etc.) may damage plastic components of the boiler as well as
plastic vent pipe materials. Such damages ARE NOT covered by warranty. It is
recommended to keep a minimum clearance of 8” from high heat sources. Observe
heat source manufacturer instructions, as well as local, state, provincial, and
national codes, laws, regulations and ordinances when installing this boiler and
related components near high heat sources.
C. REQUIREMENTS FOR INSTALLATION IN CANADA
1. Installations must be made with a vent pipe system certified to ULC-S636. IPEX is
an approved vent manufacturer in Canada supplying vent material listed to ULC-
S636. Additionally you may use AL29-4C stainless steel venting to comply with
Canadian requirements.
2. The first three (3) feet of vent pipe from the appliance flue outlet must be readily accessible for visual inspection.
