An automatically actuated regulation system for a natural gas pipeline having flow control unit, a vibration sensor, a gas flow meter, a trigger unit, and a microprocessor. The microprocessor actuates the flow control unit when two conditions are met. First, there must be a vibration which surpasses a predetermined threshold. Second, flow in the natural gas pipeline must have increased over the flow rate before the vibration. The system can be configured to store gas usage data and, in one embodiment, transmit the data to another location through the use of a modem or other communication means.

The multi-oil furnace of claim 10 wherein said central opening through said header is sealed to retain said combustion gases within said header without mingling said combustion gases with said ambient air. 12. A heat exchanger for a multi-oil furnace having a burner chamber in which fuel is burned to create heat and a flow of combustion gases, comprising: a plurality of exhaust tubes arranged in a generally circular array extending rearwardly from said burner chamber to carry said combustion gases away from said burner chamber, said array of exhaust tubes defining a diameter that is no greater than a corresponding diameter of said burner chamber; a header positioned rearwardly from said burner chamber and being connected in flow communication with said exhaust tubes to receive said combustion gases therefrom; and a blower to force ambient air around said header and past said exhaust tubes and said burner chamber to extract heat therefrom. 13. The heat exchanger of claim 12 wherein said header is formed with a central opening extending therethrough with said circular array of exhaust tubes being positioned around said central opening, said blower being operable to blow at least a portion of said ambient air through said central opening to engage said exhaust tubes. 14. The heat exchanger of claim 13 wherein said blower is operable to direct the flow of ambient air within the interior of said circular array of exhaust tubes toward a generally orthogonal back wall of said burner chamber, said air being deflected off said back wall of said burner chamber to be passed between the individual exhaust tubes before being discharged from said furnace. 15. The heat exchanger of claim 14 further comprising: a generally vertical baffle positioned forwardly of said exhaust tubes to force the flow of ambient air through a passageway to be directed against said burner chamber to absorb heat therefrom. 16. The heat exchanger of claim 15 wherein said passageway is in the form of an annular opening extending around said burner chamber. 17. The heat exchanger of claim 16 further comprising: a generally horizontal baffle apparatus mounted on said burner chamber to receive ambient air passing through said annular opening and to direct said ambient air into a generally laminar flow path along an exterior surface of said burner chamber. 18. The heat exchanger of claim 17 wherein said horizontal baffle apparatus includes a plurality of planar baffles affixed to and extending generally parallel to said exterior surface of said burner chamber. 19. A method of absorbing heat from a furnace, having a burner chamber for burning fuel to create heat and combustion gases, into a flow of cooling air, comprising the steps of: blowing said cooling air through a central opening in a header spaced rearwardly from said burner chamber and being connected to said burner chamber by a circular array of exhaust tubes for extracting said combustion gases from said burner chamber, said central opening being positioned within the midst of said circular array of exhaust tubes; directing said cooling air between said exhaust tubes; passing said cooling air through an annular opening within a generally vertical baffle positioned in generally alignment with a back wall of said burner chamber, said annular opening corresponding to an exterior surface of said burner chamber so that said cooling air passing through said annular opening passes along said exterior surface of said burner chamber; deflecting said cooling air after passing through said annular opening by a generally horizontal baffle apparatus to direct said cooling air into a generally laminar flow path along said exterior surface of said burner housing; and discharging said cooling air from said furnace. 20. The method of claim 19 wherein directing step i
