Assembly for controlling the flow of gas for gas fired artificial logs

An assembly for controlling the flow of gas for gas fired artificial logs, comprising:

• a main burner and a pilot;
• a gas valve for controlling the flow of gas to said main burner and to said pilot;
• said pilot having an opening where flame is produced;
• said pilot connected to said gas valve;
• said pilot including a oxygen depletion sensor for extinguishing the pilot flame but not the flow of gas when the surrounding oxygen reaches a predetermined level;
• a thermal responsive generator;
• said thermal responsive generator connected to said gas valve;
• said thermal responsive generator including an outer barrel;
• said outer barrel being juxtaposed to said pilot opening;
• the point of said barrel nearest said pilot opening being at a distance between 0.5 and 1.5 inches from said pilot opening, whereby said distance is such that said thermal responsive electrical generator will generate sufficient voltage to maintain said valve open when flame is emanating from said pilot opening;
• and is such that the gas coming from said pilot opening after the flame has been extinguished due to low oxygen will not permit ignition about said barrel.

An assembly for controlling the flow of gas to gas fired artificial logs comprising:

• a main burner and a pilot;
• a gas valve for controlling the flow of gas to said main burner and to said pilot;
• said pilot having an opening where flame is produced;
• said pilot connected to said gas valve, said pilot including a oxygen depletion sensor for extinguishing the pilot flame but not the flow of gas when the surrounding oxygen reaches a predetermined low level;
• a thermal responsive electrical generator generating at least 200 millivolts;
• said electrical generator connected to said gas valve;
• said generator including an outer barrel;
• said outer barrel being juxtaposed to said pilot opening;
• said outer barrel having a top;
• said top of said barrel being located above said pilot opening;
• the point on said barrel nearest said opening being between 0.5 and 1.5 inches from said opening, whereby the distance is such that said thermal responsive electrical generator will generate sufficient voltage to operate said valve when said flame is emanating from said opening, and is such that the gas coming from said pilot opening after the flame has been extinguished due to low oxygen will not permit ignition about said barrel.
