The vent system will be under positive pressure. Check
all seams for gas tightness. Allow 24 hours for silicone
to cure before operating the boiler.

NOTICE !
To increase overall vent length, use a
couple of 45° elbows on air intake piping
and run the intake piping at an angle.
NOTICE!
The follwing maximum equivalent length of
exhaust pipe (Table 7, page 24 and
Table 9, page 25) represents the maximum
equivalent length of exhaust vent pipe or air
intake pipe only, without condensate drain
tee, vent piping within the termination body
and length of the termination tee. Note that
we only need to be concerned about the
longest run; do
not
combine intake and
exhaust piping.
