1 × SIT-type magnet unit 34 mm. Gas safety parts must be fitted by a Gas Safe registered engineer and leak-tested after installation.
- Will it fit my Falcon or Imperial range?
- It is sold in the UK for Falcon Dominator and Imperial ranges with SIT small-magnet valves. Measure your old magnet (34 mm long, 12.5 mm head, 9 mm seat) to confirm.
- What does the magnet unit do?
- The thermocouple's millivolts energise the magnet and hold the gas open. If the flame goes out, the magnet releases and the valve shuts within seconds.
- My pilot will not stay lit. Is it the magnet?
- It can be, but a worn thermocouple is more common. An engineer can test the thermocouple output first.
- When will it ship?
- Same working day from UK stock, free Royal Mail 24 delivery.
