GAS CONNECTION

Checking the gas supply

1. Check the manometer zero point is correct.

2. Connect the manometer to the cooktop pressure point.

This is located on the regulator.

3. Turn on the gas supply and electricity and try to ignite

the gas.

TIPS & INFORMATION

It will take additional time to light the gas for the first time

as air needs to be purged from the pipes.

4. With the appliance operating check the outlet pressure

• when all burners of the appliance are operating

at maximum,

• when the smallest burner of the appliance

is operating at minimum.

Under these conditions the outlet pressure should not vary

from the nominal outlet pressure of 1.00kPa by more than

+/– 0.20kPa.

If the regulator appears to not be performing satisfactorily,

then check the following points.

1. If the outlet pressure is consistently too low then the inlet

pressure may be too low and adjustment of an upstream

regulator may be needed, or an upstream regulator or

valve with insufficient flow capacity may be present in

the gas supply line. If this is suspected then it may be

necessary to repeat the checks whilst

measuring both the inlet and outlet pressure to determine

if the inlet pressure is in the range 1.13 – 5kPa.

2. Check that the regulator has been fitted to the gas supply

line in the correct orientation, the arrow on the base of

the body indicates the direction of gas flow.

Once these checks have been completed, if the regulator

still fails to perform in a satisfactory manner

it should be replaced.
