Tank positioning
The tank must be placed on a stable floor, not too far from the water heater(s).
The floor must be able to hold the weight of the storage vessel(s) filled with water.

Strain on the gas valve and fittings may result in vibration, premature component failure and leakage may
result in fire, explosion, property damage or serious injury. Do not use an open flame to test for gas leaks.
Failure to follow these instructions may result in fire.

must never be able to suck on the water heater's condensate drain hose.
When mounting the bottom part of the condensate trap, before commissioning the water heater and/or
after maintenance, the condensate trap must ALWAYS be completely filled with water.
This is a safety measure: the water in the condensate trap keeps the flue gases from leaking out of the heat
exchanger via the condensate drain.
The condensate the water heater produces is acidic. Ensure that the drain, drainpipe, and anything that will
come in contact with the condensate can withstand the acidity or neutralize the condensate before
disposal.

The condensate drain is placed at the center at the bottom of the
water heater and has a ¾ inch hose discharge. Connect this flexi-
ble hose to the sewer system.
Use only plastic parts to the condensate drain. Metal parts are
not allowed.
Blockage of the drain might damage the water heater. The drain
connection is correct when the condensate can be seen flowing
away, e.g. using a funnel. Any damage that might occur, when
the drain is not installed correctly, is not covered by the warranty
of the water heater.
There should be an open connection of the condensate hose into
the sewage system. A possible vacuum in the sewage system
