5. Concentric Vertical Roof Vent Kit (54049): The
concentric vertical roof vent kit is used without a
chimney to vent through the building roof. This type
of installation is shown in Figure 3.5. Additional
concentric vent pipe components may be required to
complete the installation. Refer to the component list
for vent pipe in Table 3.2.
G. CONDENSATE
1. The disposal of all condensate into public sewage
systems is to be in accordance with local codes and
regulations. In the absence of such codes, follow these
instructions.
2. The condensate from oil-fired condensing appliances
may have a pH value as low as 2. Some local codes
require the use of neutralization equipment to treat the
condensate.
3. A condensate neutralizer (91438), available from your
distributor is recommended to reduce the acidity of
the condensate before it is piped to a drain.
4. This appliance must be fitted with a condensate trap
to prevent flue gas leakage.
5. Figure 3.6 shows a simple condensate trap that can
be utilized with this equipment. A 3/4" Female NPT x
3/4" O.D. Barb Adapter is used to attach a 3/4" ID
PVC (Tygon) Hose.
6. If the condensate outlet of the Pinnacle boiler is below
the drain level, a condensate pump must be used.
7. All piping for the condensate drain should be
corrosion resistant material such as PVC or
polypropylene. Do not use galvanized, aluminized, or
materials containing copper (such as brass or bronze)
for pipe or fittings.
