sealing.
The connection to the boiler must include a suitable method of disconnection and a gas
control valve must be installed adjacent to the boiler for isolation purposes. The nominal
inletgaspressuremeasuredattheboilershouldbe7"W.C.(18mbar)forNaturalgas
(GasA).Maximumpressurewithnoow(lockup)orwiththeboilerrunningis10.5

Always check the safety of the gas pipe system by means of a bubble test using
leak-search spray.
The boiler must be isolated from the gas supply piping system by closing its
individual manual shuto󰀨 valve during any pressure testing of the gas supply
