DROP LEVER GAS COCKS

XL1256, 1258, 1263, 1264, 1265, 1267 (Supplied with 1/4" BSP SHANK)

SPECIFICATION
Outlet connections: Fixed serrated nozzles suitable for 8mm to 13mm ID rubber nose.

Inlet Connection: 1/4" BSP shank by 65mm.

Construction: Fire safe plug cocks of brass constructed using grease suitable for Natural Gas and LPG.

Installation
Supply pressure should be in the range from 1.5 kPa to 5 kPa.

A qualified installer should be used. LPG supplies should be regulated locally in order to prevent pressure surges.

NOTE: The maximum possible pressure should never exceed 5 kPa.

Connection
Fitting connection is a 1/4" BSP male threaded shank 65mm long. The connection end of the shank is designed to fit 8mm BS 27871 Table X tubing using a compression nut.

NOTE: The use of compression fittings, if used for domestic gas or LPG, should be in accordance with gas board regulations.

Testing
All drop lever gas cocks componenets are tested at 135 kPa before despatch (based on BS 1552:1995). Finally assembleddrop lever gas cocks are tested at 13,8 kPa. Installation test pressures on systems incorporating drop lever gas cocks should NOT EXCEED 13,8 kPa otherwise the lubricant will be blown out and the cocks may leak.

A competent Gas Engineer should always test Natural Gas installations.

Leakage should be checked using soap and water or trapped pressure drop over 15 minutes.
