installed in any indoor location provided the flue gases
areadequatelyremovedandcomburentairdrawninfrom
outdoors. Provided the boiler is properly installed, the

sincethecombustioncircuitofRESIDENCE COLONNA
CONDENS boilers is sealed with respect to the envi-
ronment. If instead comburent air is drawn from inside
the boiler room itself, the room must have adequately

nicalstandards.
IMPORTANT
Before installing the boiler, thoroughly flush out all the
pipes to remove any dirt and deposits that could com-
promisethecorrectfunctioningoftheboiler.Openexpan-
sion chambers must be fitted with an overflow siphon
connectedtoadrainpoint.
Before lighting the burner for the rst time, make sure
that the boiler is congured for use with the type
of gas supplied. The type of gas is specied on the
packaging label and on the gas identication plate on
the boiler itself.
b When installing the boiler, allow sufficient space
around it to access all safety and control devices
andtopermiteasymaintenance.
b Make sure that the boiler’s index of electrical pro-
