Condensate Piping
This water heater is a high efciency, 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.
In order to drain the condensate, a 16mm(1/2") threaded tting is provided at the left side of the water heater. Do
not reduce the size of this tting or the drain piping to less than 16mm(1/2").
Use plastic pipe, such as PVC, 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 7.6 LPH(2 GPH) from the water heater.
Horizontal runs must be sloped 1/4" per 300m(984ft) towards the drain or condensate pump.
The end of the drain pipe must not be submerged in water or blocked in any way.
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.
Take measures to prevent the condensate drain lines from freezing (insulation, heat tape, electric heaters, etc.)
