7 CONNECTIONS
Tank positioning
The tank must be placed on a stable floor, not too far from the water heater(s).
NB! This floor must be able to hold the weight of the water filled tank(s).
Water heater connections
1
– Hot Water / Supply
2
– Cold Water / Return
3
– Gas
4
– Condensate trap clean out.
5
– Condensate drain
6
– Automatic air drain.
Strain on the gas valve and fittings may result in vibration, premature component failure and leakage and
may result in a 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.
Condensate drain connection
The condensate drain is placed at the center at the bottom of the wa-
ter heater and has a ¾ inch hose discharge. Connect this flexible
hose to the sewer system.
Use only plastic parts to the condensate drain. Metal parts are not
allowed.
Blockage of this drain might damage the water heater. The drain con-
nection 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 must never
give the opportunity to suck on the water heater’s condensate drain
hose.
Open connection
to the sewer.
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 neu-
tralize the condensate before disposal.
