4.6 Gas connection
The connection to the gas supply must be carried out by professionally qualified personnel in
accordance with relevant standards.
When connecting the boiler to the gas supply pipe, only use appropriate washers and gas fittings. The
use of hemp, PTFE tape and similar materials is not allowed.
In areas prone to Copper Sulphide build-up in gas supply pipes (such as in Northern Ireland) an in-line
filter should be installed upstream of the appliance.
Before installing the boiler, check that:
■
The pipe work is appropriately sized for the flow rates required and the pipe lengths installed, and must be fitted
with all the safety and control devices required by current standards;
■
The gas supply line must be a
minimum of a 22 mm diameter
pipe with a direct supply from meter to boiler and
comply with current standards and regulations;
■
Check the internal and external seals of the gas supply system;
■
A gas shut-off valve must be installed upstream of the appliance;
■
An in-line filter is installed, where necessary, and is free from blockage;
■
Before starting up the boiler, make sure that the type of gas corresponds to that for which the appliance has
been configured (see gas type label inside the boiler). Conversion of the appliance from natural gas to LPG must
only be carried out by qualified personnel;
■
Check that the gas supply pressure is between the values stated on the rating plate (see gas type label inside
the boiler);
■
Prior to installation, it is good practice to ensure that there are no machining residues on the gas supply pipe.
