Remote control of gas fireplace burner
First Claim
Patent Images
1. In an apparatus to light a fireplace that includes an elongated main gas burner associated with a grate for supporting logs, there being a valve operatively connected with the burner to control flow of combustible gas to the burner, the combination comprising:
- (a) first means including a pilot burner to produce a pilot flame for igniting gas flowing to the main burner;
(b) valve means operatively connected with the first means to(i) control gas flow to said pilot burner and(ii) control gas flow to said main burner;
(c) electrically operated control means responsive to remote transmission of RF or IR wave energy to effect flow of gas to said pilot burner by operation of said valve means, to effect operation of said first means to ignite said gas at said pilot burner, and to effect flow of gas to said main burner for ignition by said pilot flame in response to production of pilot flame,(d) and an electrical continuity sensor circuit means operatively connected with said first means and with said electrically operated control means for sensing the existence of absence of flame, for controlling repeated attempts to ignite gas flowing to the pilot burner.

10. In apparatus to ignite gas at fireplace burner means associated with grate for supporting logs or simulated logs, there being a valve operatively connected with the burner means to control flow of combustible gas to the burner means, the combination comprising:
-
(a) first means proximate the burner means for igniting gas to produce flames rising in the fireplace, (b) electrically operated control means operatively connected with the valve and with said first means, and responsive to remote transmission of RF or IR wave energy to (i) effect flow of gas to the burner means by operation of the valve, (ii) effect energization of said first means to in turn effect said ignition of gas, (iii) repeatedly sense for the presence or absence of flames to be produced in response to said ignition, (iv) stop flow of gas to the burner means by operation of the valve, in response to said repeated sensing for the absence of flames. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. In apparatus to ignite gas at fireplace burner means associated with grate for supporting logs or simulated logs, there being a valve operatively connected with the burner means to control flow of combustible gas to the burner means, the combination comprising:
-
(a) first means proximate the burner means for igniting gas to produce flames rising in the fireplace, (b) electrically operated control means operatively connected with the valve and with said first means to; (i) effect flow of gas to the burner means by operation of the valve, and to (ii) effect energization of said first means, (c) a manual control coupled to said control means, and responsive to manual actuation of said manual control to effect operation of said electrically operated control means, (d) and an electrical continuity sensor circuit means operatively connected with said first means and with said electrically operated control means for sensing the existence or absence of flame, for controlling repeated attempts to ignite gas flowing to the burner. - View Dependent Claims (20, 21, 22)
