Danger
Leaks can result in a risk of poi-
soning through escaping gas.
Prior to commissioning, check
the boiler door gasket for correct
seating and realign, if required.
Otherwise there could be an
ingress of secondary ventilation
and condensate might form on
the boiler door; gas could also
escape.
