DO NOT mix piping from different pipe manufactur-
ers unless using adapters specifically designed for the
purpose by the manufacturer.
Every joint on polypropylene vent piping must include
a locking collar.
DO NOT use cellular core PVC (ASTM F891), cellular
core CPVC, or Radel
®
(polyphenolsulfone) in venting
systems.
DO NOT cover non-metallic vent pipe and fittings
with thermal insulation.
ADAPTERS FreeStyle
®
Boiler comes with a 3”, 3-in-1
adapter as standard. This adapter allows the installa-
tion of 3” PVC schedule 40, CPVC schedule 40, PVC-DWV
schedule 40, AL29-4C stainless steel and Polypropylene
(from Simpson-Duravent only) piping without the need
for extra adapters.
It may require an adapter at terminations.
If your venting system uses Centrotherm Eco systems
InnoFlue single wall material, then an approved adapter
is required.
If using 2” piping (FS-80/120 only), where approved for
the application, provide adapters for a 3” pipe material
(mentioned above) connections and at the termina-
tions, if required.
ALL vent and air pipes require a BIRD SCREEN at each termination. Most kits do not include
the bird screens. Purchase bird screens separately from Williamson-Thermoflo or vent kit sup-
plier if not included. [Note — bird screening is integral to the 3” PVC W- T sidewall vent cap,
available for purchase from Williamson-Thermoflo . No additional screening is required.]
USE SWEEP ELBOWS FOR ALL VENT AND AIR PIPING — DO NOT use short
radius elbows for vent or air piping. Boiler performance could be affected.
