Before the boiler is used for the rst time,
the trap must be lled with water. To do this,
add approximately 1/4 litre of water via the
ue outlet before tting the ue system, or
unscrew the cap on the trap positioned under-
neath the boiler, ll it with water and ret it
Warning! Insucient water in the trap can
temporarily cause the ue gas to be expelled
into the surrounding ambient air.
