Abstract
A water heater comprising a water container; a combustion chamber adjacent the water container; a burner associated with the combustion chamber; a flue connected to the combustion chamber; a blower assembly positioned to receive combustion products from the flue and including a blower; at least one inlet having a plurality of ports which permit air and extraneous fumes to enter the combustion chamber and prevent combustion of extraneous fumes outside of the combustion chamber; a temperature sensor positioned adjacent the inlet; and a controller connected to the blower and the temperature sensor, the controller being capable of activating the blower in response to temperature changes detected by the temperature sensor.

A water heater comprising:
- a water container;
- a combustion chamber adjacent said water container;
- a burner associated with said combustion chamber;
- a flue connected to said combustion chamber;
- a blower assembly positioned to receive combustion products from said flue and including a blower;
- at least one inlet having a plurality of ports which permit air and extraneous fumes to enter said combustion chamber and prevent combustion of extraneous fumes outside of said combustion chamber;
- a temperature sensor positioned adjacent said inlet;
- and
- a controller connected to said blower and said temperature sensor, said controller being capable of activating said blower in response to temperature changes detected by said temperature sensor.
A water heater comprising:
- a water container;
- a combustion chamber adjacent said water container;
- a burner associated with said combustion chamber;
- a flue connected to said combustion chamber;
- a blower assembly positioned to receive combustion products from said flue;
- an exhaust line connected to said blower assembly to convey said combustion products away from said blower assembly;
- at least one inlet having a plurality of ports which permit air and extraneous fumes to enter said combustion chamber and prevent combustion of extraneous fumes outside of said combustion chamber;
- a temperature sensor positioned adjacent said inlet;
- a controller connected to said blower and said temperature sensor, said controller being capable of activating said blower in response to temperature changes detected by said temperature sensor;
- and
- a pressure switch positioned to detect blockage of said exhaust line and flow of air from said flue prior to initiation of combustion at said burner.
A water heater comprising:
- a water container;
- a combustion chamber adjacent said water container;
- a burner associated with said combustion chamber;
- a flue connected to said combustion chamber;
- a blower assembly positioned to receive combustion products from said flue and including a blower;
- a temperature sensor located proximate to said burner for detecting changes in temperature therein;
- a controller connected to said blower and said temperature sensor, said controller being capable of checking the status of said sensor and energizing said blower.
