Leak Detection Test Method
Leak testing of the appliance shall be conducted according to the manufacturer's instructions.
In your own interest of safety, the following procedures should only be carried out by an approved competent
person.
Before commencing any leak testing isolate the appliance from the gas supply.
For each test the system should be pressurized via the pressure test point located on the end of the manifold.
1. Leak testing of manifold
Pressurize the system – max 60" WC (150mbar). Verify gas soundness of manifold – i.e. no pressure loss.
2. Leak testing control valves
Turn all control valves to maximum setting (HI-LITE). Pressurize the system – Max. 60" WC (150mbar).
Verify all control valves are gas sound – i.e. no pressure loss.
3. Leak testing individual control valves and pipe work
Turn on the control valve to be tested to a high setting. Pressurize the system – max 60" WC (150mbar).
Temporarily block the respective burner jet and depress the control valve knob. Verify the control valve
and pipework to the respective burner is gas sound – i.e. no pressure loss. Repeat for each of the control
valves and gas circuit.
4. In all cases always use leak detector spray to locate a leak.
