All Innovation Water Heaters require an Automatic Float Vent connected to a Safety Check
valve. Both must be installed on all units, on the top of the heat exchanger dome, as shown
below. Both valves are included in the Accessory Kit shipped with the unit.
AUTOMATIC FLOAT VENT Instructions
1. All units are shipped with a hex nut in the center of the heat exchanger dome, which
protrudes through a hole in the center of the top enclosure panel. Remove this hex nut.
2. Fasten the Automatic Float Vent (P/N 99285) to top of the Service Check valve(P/N
99268), as shown below. Leave the red and black plastic caps in place on the Automatic
Float Vent.
