Abstract
Official abstract text for this publication.
A method for operating a furnace system includes initiating a start sequence comprising starting an inducer fan operative to induce an air flow through a burner assembly, a heat exchanger portion and a collector portion, determining whether an air pressure in the collector portion is above a first threshold value, starting a furnace ignition sequence including providing fuel to the burner assembly, igniting a fuel and air mixture and starting an ignition timer responsive to determining that the air pressure in the collector portion is above the first threshold value, determining whether the ignition timer has expired, determining whether the air pressure in the collector portion is above a second threshold value responsive to determining that the ignition timer has expired, and stopping the provision of fuel to the burner assembly responsive to determining that the air pressure in the collector portion is not above the second threshold value.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for operating a furnace system, the method comprising: receiving a start instruction at a controller; initiating a start sequence comprising: starting an inducer fan operative to induce an air flow through a burner assembly, a heat exchanger portion and a collector portion; comparing an air pressure to a first threshold value; starting a furnace ignition sequence including providing fuel to the burner assembly, mixing the fuel with induced ai…
