Parkinson Cowan Sonata 55 GLm Owners Handbook And Installation Instructions page 28

If you cut the plug off dispose of it safely as it will be a shock hazard
if it is inserted into a 13 amp socket elsewhere in the house.
If the ignition system doesn't work there may be a fault with the
electrical supply. First, check the socket by trying out another piece of
electrical equipment in it, if that works correctly renew the fuse in the
plug.
If the fuse keeps failing there is a fault in the cooker which must be
put right. Do not use a fuse with a rating higher than 3 amps. Do not
carry out other electrical work. Unplug the cooker and tell your installer.
