FUEL CONNECTIONS
The boiler must be connected to the methane gas supply
in compliance with the relevant standards.
Perform the following checks before making the connec-
tion:
- Check that the boiler is compatible with the type of gas
supplied.
- Check that the gas supply pipes have been thoroughly
cleaned.
- Check that the gas supply pipe is equal to or greater
in diameter than the boiler’s own gas inlet fitting (3/4”)
and that its pressure drop is less than or equal to the
difference between the supply point and the boiler.
Fit a suitably sized filter in the gas supply pipe if the gas
supply contains any solid particles.
b
The gas feed line must be suitable for the flow rate
demanded by the burner. The gas feed system
must also be equipped with all the necessary safety
and control devices required by applicable legisla-
tion and standards.
b
On completion of the installation, check that all
joints are sealed in compliance with the relevant
installation standards.
SUNDAY 30/130 B
boilers are type C sealed boilers,
and must therefore have a sealed flue gas vent pipe and
comburent air intake pipe, both of which must terminate
outdoors. The boiler cannot function without these pipes
and connections. These pipes form an integral part of the
boiler even if they are supplied in a separate kit. Coaxial
and twin pipe terminals are available.
