Direct Vent Termination Kit
When installed as a Direct Vent boiler the combustion air-inlet must also be piped directly to the outdoors using
the methods described in this section and in accordance with the CSA B139 (Canada) or NFPA 31 (USA) and
local code requirements.
Venting Options - Due to potential moisture loading (build-up) along the exterior wall,
sidewall venting may not be the preferred venting option.
The majority of the balance flue components required for Direct Vent installations are included with the
Burner Kit. Remaining components must be ordered separately. Refer to the components listed in Table
7-2 and illustrated in Figure 7-2.
