Installation & Operation Manual
(continued)
When using an existing vent system to
install a new boiler:
Failure to follow all instructions can result
WARNING
in fl ue gas spillage and carbon monoxide
emissions, causing severe personal injury
or death.
Check the following venting components before installing:
• Material - For materials listed for use with this appliance,
see Section 3 - General Venting. For polypropylene or
stainless steel venting, an adapter of the same
manufacturer must be used at the fl ue collar connection.
• Size - To ensure proper pipe size is in place, see Table 3A.
Check to see that this size is used throughout the vent
system.
• Manufacturer - For a stainless steel or polypropylene
application, you must use only the listed manufacturers
and their type product listed in Tables 3E and 3G for CAT
IV positive pressure venting with fl ue 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
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 fi t 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
3H 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 polypropylene and stainless steel vent, seal and connect
all pipe and components as specifi ed by the vent manufacturer
used; with PVC/CPVC vent, see the Installing Vent or Air
Piping Section on pages 20 and 21.
If any of these conditions are not met,
WARNING
the existing system must be updated
or replaced for that concern. Failure to
follow all instructions can result in fl ue gas
spillage and carbon monoxide emissions,
causing severe personal injury or death.
