The instrucons in this secon explain how to adjust boiler sengs to
allow for higher exhaust temperatures. These instrucons apply only for
installaons using CPVC, listed Polypropylene, or stainless steel venng. If these instrucons are

This product is equipped with safety devices to control the exhaust temperature which allows for a
variety of venng materials to be used in its nal installaon. The boiler is set up from the factory to
be installed with a PVC venng system and a built-in control to limit the exhaust temperature to be
below 149°F (65°C). In high temperature applicaons where the exhaust temperature can exceed
149°F (65°C), CPVC, listed Polypropylene (PP), or stainless steel venng must be used. The choice of
venng materials may have an impact on overall performance. Also, If the vent material is other than
PVC (CPVC, listed PP or stainless steel) follow the procedure below to adjust the internal sengs.
