" Diameter SDR-26 Pipe, 33.12"
1 — Wye concentric Fitting
Only one vent kit per each furnace or boiler is allowed.
Vent kit is for 2, 2-1/2 or 3 in. diameter pipe systems, (See
Figures 3, 4, 5, and 6 for the different applications.) Both
the combustion air and vent pipes must attach to the vent
kit. The vent kit must terminate outside of the structure and
should be installed vertically as shown in Figures 3 and 4, or
horizontal as shown in Figures 5 and 6.
NOTE: The roof vent location is preferred since it is less
susceptible to damage, has reduced chances to intake con-
taminants, and vent vapors are less visible.
NOTE: Codes and local utility requirements governing the
installation of gas fired equipment, wiring, plumbing, and
flue connections must be adhered to. In the absence of local
codes, the installation must conform with the Nation Fuel
Gas Code ANSI Z223.1 "latest edition", or CAN/ CGA B149
Installation Codes. The latest code may be obtained from the
American Gas Association Laboratories 400 N. Capitol St.
NW, Washington D.C. 20001, 1-800-699-9277 or www.aga.
