Claims56
A gas water heater comprising a water container adapted to be heated by a gas burner;
- and an enclosure surrounding said burner, said enclosure having at least one entry means adapted to allow air and extraneous fumes to enter said enclosure without igniting extraneous fumes outside of said enclosure.
A water heater having a burner adapted to combust gas to heat a water container above the burner within an outer enclosure having an opening means to admit air required to combust the gas;
- and including air and fume flow means cooperative with said opening to reduce or eliminate a possibility of fumes adjacent the enclosure being ignited outside said enclosure by a gas flame associated with said burner.
A water heater comprising a burner adapted to combust gas to heat a water containment and flow means above the burner within an outer enclosure having an opening means to air required to combust the gas;
- and air and fume flow means cooperative with said opening means to reduce or eliminate a possibility of fumes adjacent the enclosure from being ignited outside the enclosure by a gas flame associated with said burner;
- said water heater including gas shut off means having a flame detecting or sensing device located in a path of flame external to a combustion chamber of said water heater and also located in any path of flame of said fumes ignited in the enclosure.
A water heater comprising:
- means for storing or containing water;
- means forming a chamber adjacent said storing or containing means;
- a burner located in said chamber;
- and
- a flame trap associated with said chamber means permitting combustion air and extraneous gases, if present, into said chamber and capable of preventing ignition of extraneous gases outside said chamber.
A water heater comprising:
- a water tank;
- a combustion chamber located below said tank;
- a burner located inside said combustion chamber;
- a flame trap positioned in a portion of structure associated with said combustion chamber, said flame trap permitting ingress of air and extraneous gases, if present, into said combustion chamber and prevent egress of flames from said structure.
