TESTING

Checking the Function of the Regulator

The operation of the regulator can be confirmed by

connecting a manometer to the pressure test point located

on the side of the regulator body adjacent to the outlet.

With the appliance operating check the outlet pressure:

1. When all burners of the appliance are operating

at maximum,

2. 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 by more than ±20% of

the nominal outlet pressure (ie ±0.20kPa for Natural Gas).

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.

TESTING THE OPERATION OF THE GAS COOKER

Testing appliance operation

(Apparatus: manometer and connecting tube)

After installation, test the appliance and ensure that it

operates correctly, before handing it over to the customer.

The following procedure is recommended:

• Check that the manometer zero point is correct; then

connect the manometer to the appliance pressure test

point. This is located on the Regulator or L.P.G. Inlet

Fitting behind the kick panel (or under the Storage

Drawer where fitted).

• Turn on the gas supply and electricity (if applicable)

and attempt ignition. (For correct procedure, refer to the

Ignition Instructions.) Note that additional time needs

to be allowed for the initial lighting as air has to be

purged from the pipes.

• Check the operating pressure for the particular

gas-type, as given in the Table on page 23.

For L.P.G. appliances, the regulator in question may be

remote from the appliance.

For Natural Gas appliances

Regulators are supplied pre-adjusted and configured by the

component maker for use with Natural Gas. The appliance

installer is not required to make an adjustment to obtain the

correct outlet pressure setting.

An arrow on the base of the regulator indicates the direction

of gas flow when the inlet and outlet of the regulator are

orientated correctly. When the regulator has been fitted

check for leaks from the connections with soapy water.
