Bosch AquaStar Horizontal Vent Terminator #AQ3 Customer Review


One clarification for the manufacturer description:
the two itemized gear clamps are for flex inlet tubing;
Z-VENT stainless exhaust sections include all necessary built-in gear clamps.

J. D. Weekley was misled by his authorized installation professional:
1) The only aluminum in the kit is flex inlet tubing. Bosch specifies aluminum, PVC or galvanized for inlets.
2) 3 or 4 inch stainless category III exhaust can be used, but 3 is a better fit.
4 inch requires a 3-to-4 inch increaser.
Bosch specifies a 3 ft minimum exhaust length;
using 4 inch might increase that minimum.

Another consideration is that 3 inch diameter is less likely to require damaging webs when run thru cinder block walls.

The thru-wall vents provided for exhaust are not long enough for cinder blocks;
an additional 6-inch length of Z-VENT will be needed.

One consideration not addressed by this kit is condensate disposal when a drain is not within reach of
the drain tube supplied with the heater.

For whatever reason, parts slide together so that
leading edges of inner pipes are facing exhaust gas flow,
contrary to conventional flue pipes.
