2. insert the clamp "D" into convertor
"A" in the "C" side.
3. insert the adapter "E" into connection
"C" of the convertor "A";
4. use the precedent clamp "D" to
mechanically secure the adapter "E"
to the adapter "A". To do this tighten
the half clamp on the adapter "A"
and half clamp on the adapter "E".
A = Two pipes boiler adapter
B = Flue exhaust connection
C = Air intake connection
D = Fixing clamp
E = PVC/CPVC adapter
F = Fixing clamp
G = PVC/CPVC pipe
H = 90° elbow

Tight the clamps with a tork of 1.5 - 2
lbf ft (2-3 Nm).
5. insert the clamp "F" into convertor
"E".
6. insert the air inlet PVC/CPVC pipe,
for 2" into the adapter "E";
7. use the precedent clamp "F" to
mechanically secure the pipe to
WARNING!!!
Check stamped
arrow on boiler adapter for the
correct side of fl ue exhaust and
air intake. Failure to follow this
warning could result in excessive
levels of carbon monoxide or a
fi re, which can result in severe
personal injury or death!
WARNING!!!
Do not insulate
PVC/CPVC exhaust pipe nor
install into an enclosure or
any other obstruction thereby
preventing the cooling of the
exhaust pipe. Failure to follow
this warning could result in
excessive levels of carbon
monoxide or a fi re, which can
result in severe personal injury or
death!

the adapter "E". To do this tighten
the half clamp on the pipe and half
clamp to the adapter "E". Tight the
clamps with a tork of 1.5 - 2 lbf ft
(2-3 Nm).
Vent connection (see Figure
10-8 Item "B")
. This connection
is used to provide a passageway for
conveying combustion gas to the
outside. Vent piping must be supported
per the National Building Code, Section
305, Table 305.4 or as local codes
dictate.
To connect a PVC/CPVC pipe to the
vent connection proceed as follow
while referring to Figure 10-8:
1. install boiler adapter "A" above
boiler. Rotate boiler adapter "A" so
as air intake and vent connections
are in the desired left or right side.
Check stamped arrow to understand
which is the vent and air intake
connection.
WARNING!!!
Check
stamped arrow on boiler adapter
for the correct side of vent.
Failure to follow this warning
could result in excessive levels
of carbon monoxide or a fi re,
which can result in severe
personal injury or death!
2. Insert one side of clamp "D" onto the
air intake of boiler adapter "A" (side
C).
3. Insert adapter "E" into side "C" of
boiler adapter "A";
4. Use clamp "D" to mechanically
secure adapter "E" to boiler adapter
"A". To do this, tighten one side of
clamp "D" onto boiler adapter "A"
and the other half of clamp "D" onto
adapter "E". Tight the clamps with a
tork of 1.5 - 2 lbf ft (2-3 Nm).
5. Insert clamp "F" into adapter "E".
6. Insert the PVC/CPVC pipe "G", into
adapter "E" for at least 2";
7. Use clamp "F" to mechanically
secure pipe "G" to adapter "E". To
do this, tighten one side of clamp "F"
onto pipe "G" and the other side of
clamp "F" to the adapter "E". Tight
the clamps with a tork of 1.5 - 2 lbf ft
(2-3 Nm).
