Corrosive Contaminants and Sources
Failure to follow all instructions can result
in flue gas spillage and carbon monoxide
emissions, causing severe personal injury
or death.
WARNING
When using an existing vent system to
install a new boiler:
Check the following venting components before installing:
• Material
- For materials listed for use with this appliance,
see Section 3 - General Venting, Table 3A. For stainless
steel venting, an adapter of the same manufacturer
(Table 3B) must be used at the flue collar connection.
• Size
- To ensure proper pipe size is in place, see Table 3C.
Check to see that this size is used throughout the vent
system.
• Manufacturer
- For a stainless steel application, you
must use only the listed manufacturers and their type
product listed in Table 3A for CAT IV positive pressure
venting with flue producing condensate.
• Supports
- Non-combustible supports must be in place
allowing a minimum 1/4" rise per foot. The supports
should adequately prevent sagging and vertical slippage,
by distributing the vent system weight. For additional
information, consult the vent manufacturer’s
instructions for installation.
• Terminations
- Carefully review Sections 3 through 5 to
ensure requirements for the location of the vent and air
terminations are met and orientation of these fit the
appropriate image from the Sidewall or Vertical
options listed in the General Venting Section. For
stainless steel vent, only use terminations listed in Table
3B for the manufacturer of the installed vent.
• Seal
- With prior requirements met, the system should be
tested to the procedure listed in parts (c) through (f) of
the Removal of an Existing Boiler Section on page 11.
With stainless steel vent, seal and connect all pipe and
components as specified by the vent manufacturer used; with
PVC/CPVC vent, see the Installing Vent or Air Piping Section
on page 16.
WARNING
If any of these conditions are not met, the
existing system must be updated or
replaced for that concern. Failure to
follow all instructions can result in flue gas
spillage and carbon monoxide emissions,
causing severe personal injury or death.
