3. The inlet air cap must terminate at least 3 feet (0.91 m) lower than the flue gas outlet, if located within a 10
foot (3.05 m)
radius.
4. The inlet air cap and flue gas outlet should be located on the same roof top surface for vertical remote air.
5. For horizontal remote air, it is best to locate the inlet in a wall with wind pressure similar to the wind pressure
on the vent.
6. The inlet cap must be installed at least one foot (0.3 m) above the rooftop or at least 18" above grade and at
least one foot (0.3 m) above possible snow levels.
7. To avoid a blocked inlet condition, keep the inlet cap clear of snow, ice, leaves, debris, etc.
8. A horizontal remote air inlet must extend one foot beyond the wall.
9. A horizontal remote air inlet terminal must not be installed closer than 3 feet (0.91m) from an inside corner of
an L-shaped structure.
10. A vertical remote inlet less than 10 feet (0.91 m) from a parapet wall must be a minimum of 2 feet (0.61 m)
higher than the parapet wall.
11. Follow all requirements in the General “Venting” section of this manual and other instructions and markings
for venting flue products to the outdoors, obtaining adequate combustion and ventilation air and general
installation instructions.

CONDENSATE NEUTRALIZATION & DISPOSAL
As a result of high efficiency operation, PLATINUM
water heaters produce significant amounts of condensate.
Condensate occurs naturally when water vapor in combustion gases is cooled below the dew point. Although
only slightly acidic, PLATINUM
condensate can be routed through an optional neutralization system to become
pH neutral, allowing for disposal into any drain or sewer system.
The PLATINUM
condensate drain exits through the left support stand. Connect this 3/4" PVC pipe to a suitable
drain or to the drain through an optional PVI condensate neutralization system. This drain is the exit for
condensate occurring in the heater, as well as condensate occurring in the vent.
The optional PVI condensate neutralization system contains a neutralization bath filled with crushed limestone.
Condensate slowly flows through the limestone bed and is neutralized, thus avoiding chemical treatment or
dilution using substantial quantities of tap water. If the condensate pH is lower than 4 when checked with a pH
meter or pH paper, consult the factory for a replacement neutralization system.
Condensate drainage from the PLATINUM
will only occur after a recovery run cycle. If no condensate is drained
during this time, the drainpipe should be inspected for blockage. There is a see through cleanable trap located
beneath the unit inside the lower front jacket cover. If the water heater is not installed on a housekeeping pad to
ensure gravity drainage, a means of removing condensate, such as a pump, must be applied to the system.
WARNING:
High Voltage Shock Potential - Turn off all electrical service to the appliance when accessing
the gas valve, condensate trap, blower, hot surface ignitor and other components located inside the
lower front and rear panels. After access, close and fasten the lower front and rear panel covers before
restoring electrical service to the appliance. Wires and terminals, such as the gas valve terminals carry
High Voltage (120V). If the electrical service is not turned off, or if the covers are not replaced, and these
terminals are touched, a dangerous shock causing personal injury or loss of life could occur.
