WARNING:
Vent pipes must be adequately and securely
supported; the vent weight must not be supported by the
heater; this may cause unwarrantable damage.
Venting of the XTherm with polypropylene vent material
requires the D-33 adapter kit available from Raypak.
The polypropylene vent adapter should appear as in
Figure 44
. The standard high limits [up to 240°F (116°C)
for boilers, 200°F (93°C) for water heaters, 180°F (82°C) for
pool heaters] may be used.

CAUTION:
The inlet water temperature to the
XTherm must not exceed 190°F at 100% fire to use the
polypropylene venting option. The venting system must
conform to local codes and/or the current edition of the
National Fuel Gas Code ANSI Z223.1/NFPA 54.
Cleaning
Prior to installing Polypropylene pipe and fittings, ensure
that all gaskets are free of grease, oil, debris or damage.
Installation
Vent pipes are joined by push-fit connections, with EPDM
gaskets located in the sockets. Pipes and components
must be installed with the socket ends to the outlet and
male ends towards the appliance.
It is not recommended to install polypropylene when the
material temperature is below 32°F (0°C).
Joining
Lubricate gaskets and male ends of pipes with
CENTROCERIN™ lubricant or water only. Push male
ends of pipes into gasketed openings with a light twisting
motion.
Cutting
Components should be selected to minimize cutting.
Where it is necessary, pipe sections may be cut to length
at male ends (non-socketed end) only. Any cuts must
be made at right angles to the pipe. Pipe must then be
beveled for insertion into the adjoining socket to ease
installation. All field cuts must be deburred. Bends and
other preformed components must not be cut.
Termination
Termination should be accomplished using the adapter as
shown in
Figure 44
.
Polypropylene Construction
• ULC-S636 Certified, making it approved for use in
Canada
• Zero Clearance to Combustibles
Storage
Components should be stored in a clean, dry environment
in their original packaging. Non-UV stabilized plastic
components must be protected from prolonged exposure
to UV light.
Appliance Start-Up
Once polypropylene installation is complete, the heating
system and flue should be commissioned following
Raypak’s instructions. There is no cure time or wait time
required.
