2.11 Gas smell
Warning
Immediately shut the main gas tap. Do
not light any fire or switch on any lights,
do not use any electrical switches or
alarm bells. Open windows. Thoroughly
inspect all gas connections and, if the
gas smell persists, alert the local gas
company and/or your installer.
2.12 Condensation
If the appliance is filled with cold water
or if the hot water consumption is very
high, condensation of flue gasses will
occur on the cold surfaces of the
combustion chamber and the flue tube.
The water drops will fall on the burner
and cause a sizzling noise. This is a
normal phenomenon that will disappear
as soon as the appliance reaches its
normal operating temperature.
Important warning
The applicance should NEVER be
taken into operation with a closed
cold water supply!
Provision should always be made
for expansion.
