Testing for gas leaks.
- Leak testing of the appliance shall be conducted according to the manufacturer’s instructions.
- The appliance and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system in excess of 1/2 psi (3.5kPa).
- The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures at or less than 1/2 psi (3.5 kPa).
- Maximum inlet gas supply pressure 20” W.C. (5 kPa)
- Minimum gas supply pressure for regulator testing 5” W.C. Natural Gas, 12” W.C. LP Gas.
After installing the gas supply and making all connections, check thoroughly for possible leaks:
- Turn all control dials on unit to “OFF” position.
- Open the valve on the gas supply.
- Using a leak detection fluid (eg Rocol leak detection spray), check each gas connection one at a time by spraying or brushing the solution over the connection. The presence of bubbles will indicate a leak.
- If necessary, tighten the fitting and recheck for leaks.
- Turn on burner valve and light each burner.
- Check for a clear blue flame without yellow tipping. If burners show any abnormalities, check that they are located properly and in line with the injector orifice.
