– Loosen the fixing nuts (2) and (3) on the gas

supply pipe to the pilot flame.

– From inside the pilot flame assembly (4) remove

the compression ring (5) and the pilot injector
(6). Replace the pilot injector with the one
suitable for the new gas. Fig. 18.

- For natural gas and LPG, remove the screws
that hold the elbow (7) and fit in the suitable
diaphragm.

- Reat all the components in reverse order.

- Please note that in boilers which have been
converted from town gas to natural gas, the valve
pressure governor must be sealed. Turn the
screw clockwise to increase pressure and vice­versa.

- Stick on the label corresponding to the new gas
on the burner holder manifold.

G100IE boilers

- Remove the three injectors (1) from the burner
holder manifold using a 22AF spanner and
replace them with the appropriate ones for the
new gas. Fig. 19.

- Remove the screws that hold the elbow (7) and
replace the diaphragm with a suitable one.

- Refit all the components in reverse order.

- Stick on the label corresponding to the new gas
on the burner holder manifold.

Important Recommendations

- If the boiler is located in a frost-risk area, some
anti-freeze product should be added to the water
in proportion to the minimum outside
temperature of the place.

- We recommend that the properties of the water
in the system be:
pH: 7.5 ÷ 8.5
Hardness: 8 ÷ 12 French degrees*
(*) One French degree is equivalent to 1 gram

of calcium carbonate per 100 litres of water.

- Should it become absolutely necessary to add
water to the system, wait until the boiler is
completely cold before doing so.

- Flue limit thermostat for the products of
combustion (G100/20 to 50, G100/GTA,
G100/20 to 50IE and G100IE/GTA boilers).

The boiler incorporates a safety system which
detects an inadequate evacuation of flue gases. It
includes a thermostat which is triggered when
overheated flue gases go through the draught
diverter, thus causing the gas valve to shut off.
Before starting up the boiler again, remember to
reset the corresponding thermostat manually.
This device should never be out of service.
Please note that only original parts from the
manufacturer should be used in replacement of
faulty components.
Should the boiler ”lock out” repeatedly, the
evacuation fault should be rectified accordingly and
then a test run carried out.

- Limit the noise level of the system.

Should the risk of nuisance noise level exist, the
following steps could be adopted:

- Insulate the pump.

- Insulate the boiler, if necessary.

- Lay the pipes with vibration isolation stays/
mounts.

- Re-size the pipes.

- Limit the number of elbows and non-insulated
built-in pipes.

Note:

Characteristics and performance qualities subject
to change without notice.

CE Marking

The G100, G100IE, G100/GTA and
G100IE/GTA boilers comply with the
European Directives 89/336/EEC on
Electromagnetic Compatibility, 90/396/EEC
on Gas Appliances, 73/23/EEC on Low
Voltage and 92/42/EEC on Efficiency.
