Abstract
An integrally formed metal burner ring has a coil spring with a reduced center coil inserted in the burner inlet. Upon insertion of a fuel supply tube into the coil spring the center coil frictionally engages and seals over the supply tube and the spring is expanded to engage and seal against the burner inlet. An ignitor with a hollow tubular refractory holder has a hollow tubular electrode disposed in the hollow of the holder. The holder has a flat end face as an arc discharge surface with the end of the electrode flush with the discharge surface. The holder is secured in an aperture provided in a recess in the burner ring by orbital staking.
