e)A venting system shall terminate at least 3 feet above any forced air inlet located within 10 feet.

f)Adjacent brick or masonry surfaces must be pro- tected with a rust-resistant sheet metal plate.

g)Multiple Outdoor Vent installations require a four

(4) feet clearance between vent caps.

NOTE: Condensate can freeze on the vent cap. Frozen condensate on the vent cap can result in a blocked flue condition.

The Stainless Steel non-restricted vent cap must be furnished by the boiler manufacturer in accor- dance with its listing.

The outdoor vent terminal must be installed in a hori- zontal position to prevent recirculation of flue products. The vent cap must be mounted directly on the vent pipe of the boiler.

NOTE: In areas of high winds (alleyways, air handlers, etc.), a downward 90° - elbow must be mounted on the combustion air inlet to prevent any air flow fluctuation.

CONDENSATE DRAIN

WARNING: All condensation should be disposed of according to local, county, state, and federal laws. Refer to NFGC, section 7.9, for additional information.

The Condensing Heat Exchanger (CHX) can generate up to 1 (one) gallon per hour (gph) of condensate for every 100,000 BTUH. The maximum condensation rate for the ADB 751 is 7.5 gph, the ADB 1001 is 10 gph, and the ADB 1501 is 15 gph.
