SECTION IV: INSTALLATION
Horizontal Venting, Power Vent 1-pipe termination
This water heater may be vented horizontally (through a sidewall) with a one-pipe
termination. In this case, the water heater will be utilizing air from inside the building for
combustion air. A single hole through the exterior of the building is required for the vent
pipe.
Note: If air from inside the building will be used for combustion air, the require-
ments in Section III, “Unconfined Space” must be met.
All clearances must comply with local codes or the latest edition of NFPA 54/ANSI Z223.1
or CSA B149. See Figure 15 and Table 7 for vent terminal clearances.
