Abstract
A pre-startup control method for a boiler or water heater includes: providing a controller operatively coupled to a boiler or water heater unit; performing a unit shutdown operation; enabling a pre-start up mode; at about a same time or in any order, moving an air fuel valve by a controller to a non-off position with a gas supply to the water heater or boiler turned off, wherein the controller turns on a blower at an operational level, and causes an ignitor to spark; and displaying parameters which allow an affirmation of a safe and reliable ignition prior to a gas turn on of the boiler or water heater unit. A flow balancing method and a programmed auto run method are also described.
