Installation & Service Manual

5Conventional and sidewall venting

The Shield water heater may be installed with a single pipe carrying the flue products to the outside while using combustion air from the equipment room. The vent pipe may terminate either vertically (FIG. 5-1) above the roof line in a conventional vent manner or on a sidewall (FIG. 5-2).

Follow the requirements in the General Venting, Sidewall Direct Venting, and Vertical Direct Venting sections for vent material specifications, vent length requirements, and vent termination requirements.

Combustion and ventilation air must be supplied to the equipment room per the requirements on page 15 of this manual for proper operation of the Shield water heater when utilizing the single pipe method.
