NOTE: Consult your venting pipe supplier for assistance with sizing of vent
materials and other potentially required accessories.
3. Do not use boot tees or bullhead tees.
4. Barometric dampers should never be used in a condensing boiler
application even if the draft is negative, this is because barometric
dampers physically open to the mechanical room and it will be possible for
fl ue gas condensate to drain down the outside of the stack.

5. The air intake system must be designed to prevent any moisture from
draining to the boiler.
6. The layout of the piping used for air intake and exhaust must be done in a
way that facilitates smooth travel and natural fl ow. Performing a pressure
drop calculation isn't enough information to make sure a draft system will
perform adequately. Good practice must be used by the designer and
installer. Some recommendations:

Avoid sharp turns, boot tees, bullhead tees, back-to-back 90
degree elbows, short radius elbows especially right at the
connections to the boilers

Avoid extensive direction changes (fl ue gases being required
to turn around)

Never direct fl ue stacks in a downward direction.

INSTALLATION
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.
