Gas control valve for BFM 120
1. Isolate the appliance from the power supply (10.3 "Isolating the appliance
from the mains").
2. There are two test nipples on the gas control valve. Test nipple (6) is used
to check the supply pressure. The other test nipple on the gas control valve
is not used. The manifold test nipple (8) is used to measure the burner
pressure.
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.
3. Connect a pressure gauge to the manifold test nipple (8).
4. Open the gas supply and bleed the air from the mains gas supply via test
nipple (6).
5. Connect a pressure gauge to the manifold test nipple (6) when gas starts to
flow from this nipple.
6. Switch on the power to the appliance using the isolator on the appliance.
7. Set the control thermostat to the maximum temperature and start the
appliance running by setting the ON/OFF switch to position I.
8. The heating cycle will start, and after a short time the burner tray will ignite.
9. After the burner tray has ignited, wait approximately 1 minute before reading
the dynamic pressures.
10. Use the pressure gauge to read the supply pressure at test nipple (6). Refer
to the gas data table (3.4.3 "
Gas data").
Note
Consult the mains gas supply company if the supply pressure is not correct.
