Gas Connections And Tightness Testing - Potterton SIRIUS FS Installation & Servicing Instructions Manual

5.6 GAS CONNECTION AND TIGHTNESS TESTING
5.6.1 Gas Supply
This boiler is designed to operate using Natural Gas (G20) only. DO NOT attempt to
convert or operate this boiler using LPG (G31).
The data plate on the boiler must be checked with the local supply conditions of
the gas supply before installation can commence. Gas used should have sulphur rates
inside the European standards in force. An annual average rate of 30mg/m
with peaks of 150mg/m
A manual valve for isolation of the gas supply to the boiler should be installed
nearby and it should be clearly identified and readily accessible for use at all times.
The installation of the gas supply must conform, to the standards and codes of
practice in force at the time of installation (see section 2.3 for guidance). It is
recommended that the gas supply pipe work is fitted with a suitable union so that
the boiler can be safely removed for major service or repair.
The gas meter, regulator and supply pipe work must be sized so as to provide an
adequate supply to the boiler in addition to any other appliances connected to the
supply. (See section 3.2 for G20 gas consumption rates)
5.6.2 Gas Connection
A Male 2" BSP steel gas connection is provided at the top of the boiler. A running
pressure of 20.0mb (+/- 1.0mb), must be available at the boiler supply inlet, with this
boiler and other connected appliances operating at maximum output.
5.6.3 Tightness Testing
The entire gas inlet pipe must be checked for leakages before commissioning, up to
a maximum pressure of 150mbar. The gas line has to be purged of air before
commissioning following the guidelines set out in IGE/UP/1. Check for tightness of
any disturbed joints using a leak detector fluid after purging.
