INSTALLATION
air inlet of the boiler.
2. The air intake must be piped out of the building if the boiler room contains
contaminated air.
3. Air Intake pipes and fi ttings shall be Schedule 40 PVC pipe or galvanized
steel. All Schedule 40 PVC pipe, fi ttings, primer and cement must conform
to American National Standard Institute and the American Society for
Testing and Materials (ANSI/ASTM standards) per pipe manufacturer’s
requirements.
4. Intake PVC piping must be assembled using cement. This will ensure that
the intake is air tight and will not allow contaminates from the boiler room
into the boiler. The cement must be free fl owing and contain no lumps,
undissolved particles or any foreign matter that adversely aff ects the joint
strength or chemical resistance of the cement. The cement must not show
gelation, stratifi cation, or separation that cannot be removed by stirring.
5. Adhere to procedure for cementing joints (per ASTM D2855).
Air Filter
The air fi lter requires monthly maintenance. See Maintenance section of this
manual.
Exhaust Venting
The Endura is equipped with a vent connection at the lower rear of the boiler.
Adhere to the following for installation:
1. The Endura is a Category II/IV appliance, thus venting material must be
appropriate for condensing, positive pressure applications. Any venting
material supplied for the Endura boiler must be AL29-4C or 316L SS, listed
and labeled to UL1738, and guaranteed appropriate for the application by
the manufacturer and supplier of the venting. It is also acceptable to vent
the Endura Cat. II (negative pressure, condensing).
2. The exhaust line must be sloped down toward the drain with a pitch of
at least 1/4” per foot (6.35 mm per .3 m). Failure to do so can result in a
condensate pocket, which can result in an inoperative boiler. There must
be no low spots in the exhaust pipe, as this can also result in a condensate
pocket. A high spot is acceptable, provided the pitch from the high spot
is maintained back to the boiler or to the outside point of the exhaust.
Always avoid rigid connections between piping and structural members of
the building.
3. Follow vent manufacturer’s instructions for installation of exhaust venting.
Refer to table for acceptable venting materials. Use of cellular core PVC
(ASTM F891), cellular core CPVC , or Radel® (polyphenolsulfone) in venting
systems is prohibited.

WARNING
Cements for plastic pipe are
fl ammable liquids and should
be kept away from all sources of
ignition. Proper ventilation should
be maintained to reduce the hazard
and to minimize breathing of cement
vapors. Avoid contact of cement with
skin and eyes.
Never install a barometric damper on
fl ue systems designed with positive
pressure.
Assure all electrical connections are
powered down prior to attempting
replacement or service of electrical
components or connections of the
boiler.
Do not use the boiler/burner as
support for ducted air piping.
Ducted piping must be supported
independently of the boiler.
Particulate matter or chemicals in
the combustion air supply to the
boiler will cause damage or failure to
the burner and is not covered under
warranty.
Regular maintenance of the
fi lter is required (as per the fi lter
manufacturer’s recommendations) to
maintain the Endura warranty.
Negative pressure in the boiler room
can cause operational issues and
boiler damage.
