  • the water heating device 1 may include a soot preventing glass 440.

  • the glass 440 may have a size of an outer diameter corresponding to an inner diameter of the sub part end 402-1.
  • the outer diameter of the glass 440 may be formed to be larger than an outer diameter of the lens 435, but the present disclosure is not limited thereto.
  • the glass 440 may be a quartz glass, by which diffusion or adsorption of the soot may be restrained, and may be a complex glass including the quartz glass. Because the glass 440 is disposed around the sub part end 402-1 (or the lens 435), diffusion or adsorption of the soot may be restrained whereby it may be more advantageous for the flame detecting sensor 400 to sense the flames.
  • thermal damage to the flame detecting sensor or generation of soot due to the combustion gas may be restrained.
  • a durability of the flame detecting sensor may be enhanced.
  • an emergency situation may be effectively monitored by restraining damage to the flame detecting sensor.
