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:
1
Turn all control dials on unit to “OFF” position.
2
Open the valve on the gas supply.
3
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.
4
If necessary, tighten the fitting and recheck for leaks.
5
Turn on burner valve and light each burner.
6
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.
