INSTALLATION VTG-IOM-2012-1001 SECTION 2
Exhaust Venting
The Vantage is equipped with a vent connection (Figure 4) at the lower rear of
the boiler.
Adhere to the following for installation:
1. The Vantage is a Category IV appliance, thus venting material must be
appropriate for condensing, positive pressure applications. Any venting
material supplied for the Vantage boiler must be AL29-4C or 316L SS, listed
and labeled to UL1738, and guaranteed appropriate for the application by
the manufacturer and supplier of the venting. It is also acceptable to vent
the Vantage Cat. II (negative pressure, condensing).
2. The exhaust line must be sloped down toward the drain with a pitch of
at least 1/4” per foot. Failure to do so can result in a condensate pocket,
which can result in an inoperative boiler. There must be no low spots in
the exhaust pipe, as this can also result in a condensate pocket. A high
spot is acceptable, provided the pitch from the high spot is maintained
back to the boiler or to the outside point of the exhaust. Always avoid rigid
connections between piping and structural members of the building.
3. Follow vent manufacturer’s instructions for installation of exhaust venting.
4. The condensate connection on the boiler should be piped into the stack
drain piping. The pipe from the boiler directed to the drain should be
installed at a slope of ¼” per foot.
5. Ensure that the condensate drain piping will not be exposed to
temperatures where water/condensate will freeze in the lines.

! WARNING
Do not terminate venting into an
enclosed area.
Never use open ame or smoke from
a cigarette, cigar, or pipe as a testing
method during boiler installation,
operation, or maintenance.
Foreign substances, such as
combustible volatiles in the
combustion system can create
hazardous conditions. If foreign
substances can enter the air stream,
the boiler combustion air inlet must
be piped to an outside location.
Ensure tank return line is not clogged.
Obstructions in the line could cause
damage to the pump seal.
Regular maintenance of the
lter is required (as per the lter
manufacturer’s recommendations) to
maintain the Vantage warranty.
