3.11.2Procedure to check pressures

1.There are two test nipples on the gas control:

-a supply pressure nipple (1)

-a burner pressure nipple (2)

Sealing screws are located inside the test nipples. Loosen both sealing screws by a few turns. Do not completely loosen them; they can be difficult to re-tighten.

2.Connect a pressure gauge to the burner pressure nipple (2).

3.Open the gas supply and vent the gas supply line with the supply pressure nipple (1).

4.Connect a pressure gauge to the supply pressure nipple (1) when gas starts to flow from this nipple.

5.Switch on the power to the appliance using the isolator on the appliance.

6.Switch the electronic controller ON by setting the 0/I switch to position I.
