TYPICAL INSTALLATION
Condensate Piping
This water heater is a high ef  ciency, fully condensing appliance which produces condensate during operation.
The water heater incorporates a collection, neutralization, and removal system which must be properly drained in
order to ensure proper operation of this appliance.
Please use PVC or CPVC for the drain line. Do not use steel, black iron, or any other material which can
corrode when placed into contact with condensate water.
Keep the length of the drain pipe as short as possible. Long runs or applications where the nearest drain is above
the water heater will require the use of a condensate pump. Size the pump to allow for a maximum condensate
discharge of 2 GPH from the water heater.
Horizontal runs must be sloped 1/4" per foot towards the drain or condensate pump.
Be sure to check that condensate is freely flowing from the drain piping after the system has been installed.
Condensate will begin
 owing out of the water heater within 15 minutes after operation has started.

CAUTION
!
In order to drain the condensate, installing the condensate T  tting in the accessory kit is required. Do not reduce the size
of the  tting or the drain pipe. The condensate T  tting is designed to  t on 1/2" PVC (schedule 40, ASTM-1785) or 3/4"
CPVC (SDR11, ASTM-D2846) pipe.
The end of the drain pipe must not be submerged in water or blocked in any way.
Take measures to prevent the condensate drain lines from freezing is required (insulation, heat tape, electric heater, ect.)
