SECTION 2 VTG-IOM-2016-1214 INSTALLATION
! WARNING
All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct, and strict
adherence to applicable jurisdictional/
professional codes and regulations.
7. Avoid sidewall exhaust with roof terminated intake air. This can lead to
reverse stack eect when the boiler is idle.
Exhaust Venting
The Vantage is equipped with a vent connection 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 (2.12 cm/m). 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. Connect to the boiler exhaust using an appropriate appliance adapter (not
supplied). A minimum 1ft (305mm) straight length before the rst elbow is
recommended. Do not use boot tees or bullhead tees. See Figure 19.
NOTE: Adequate provision must be made to support the weight of the exhaust
venting. It cannot be supported by the boiler exhaust connection.
4. Follow vent manufacturer’s instructions for installation of exhaust venting.
5. 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 (2.12 cm/m).
6. Ensure that the condensate drain piping will not be exposed to
temperatures where water/condensate will freeze in the lines.
Common Venting Layouts for Vantage
It is possible to combine the air intake and/or exhaust venting of multiple
Vantage boilers. The pressure drop across the entire common system, the
combined total of both air intake and exhaust, must comply with the draft
pressure requirements for an individual boiler, see Table 5.
Refer to Figure 19 and adhere to the following for installation:
1. Consult your venting supplier for guidance in designing common vented
installations. It is imperative to design such systems to prevent backow of
exhaust gases through idle boilers.
