Check the eco and thermostat units with an ohm meter. They should both be closed for the heater to light. Failures of the ECO are quite common. The eco and stat are purchased as a set for about $12.
Also check the coil of the gas valve, it should be 20 ohms measured from the double red wires at the eco to ground.
