CHAPTER 4 - INSTALLATION REQUIREMENTS
4.1. Vent/Combustion Air Transitions
4.1.1 3” to 2” (60 mm) Transitions
This chapter outlines the installation of 2” (60
mm) Venting and Combustion Air Piping for
the INSTINCT units when the vent system must
transition from the 3” outlet of the boiler to the
2” (60 mm) vent system.
1. The transition from 3” vent system to 2” (60 mm)
vent system must occur at the boiler vent outlet.
2. The transition from 3” vent to 2” (60 mm) vent must
occur in a vertical run only.
Transition of 3” vent to 2” (60 mm) vent in a
horizontal run will result in pooling of the
condensate and potential vent blockage. Fail-
ure to transition from 3” vent to 2” (60 mm)
vent in a vertical run can result in substantial
property damage, serious injury, or death.
3. Use a 3” x 2” bell reducer to make the transition to
2” CPVC/PVC vent, see Figs. 21 and 22.
4. Use a 3” appliance vent adapter and 3” (80 mm) to 2”
(60 mm) reducer to make the transition to 2” (60 mm)
Polypropylene vent. See Table 2 on page 4.
5. The 2” (60 mm) vent must not transition back to 3”
(80 mm) vent at any point in the vent system.
6. The PVC combustion air piping shall transition from
3” to 2” using a 3” x 2” bell reducer and shall transition
in a similar manner as the vent system.
7. The total equivalent length of the 3” (80 mm) and
2” (60 mm) vent piping combined shall not exceed
the length listed for a 2” (60 mm) vent system in Ta-
ble 6 on page 7.
8. The total equivalent length of 3” (80 mm) and 2” (60
mm) combustion air piping combined shall not ex-
ceed the length listed for a 2” (60mm) combustion
air system in Table 6 on page 7.
