How a Pellet Stove Works

Once a pellet stove is powered on, it begins a start-up cycle lasting between 5-15 minutes depending on the manufacturer settings. This allows the heat level to reach minimum levels for temperature sensors to take over stove operation until the stove is turned off. In general, pellet stoves all follow the same basic sequence of operation:

1.Turn stove "ON".

Many stoves use a manual switch, but some may be controlled by a millivolt thermostat or remote.

2.Combustion motor begins to run.

The combustion blower pulls fresh air into the firebox and vents the exhaust outside. This forced draft enables the pellet stove to burn efficiently.

3.Vacuum/Pressure switch closes.

The pressure switch detects the airflow inside the stove to support safe operation. Once satisfied, this safety sensor closes and allows the stove to proceed with the start-up cycle.

4.Igniter heats up.

The igniter element should glow cherry red within 2 minutes. Some “cool tip” style igniters may not heat up all the way to the end.

5.Feed system delivers fuel.

This feed rate is customizable depending on your desired heat level and the type of fuel. Some pellet stoves require premium pellets while others can burn corn, sunflower seeds, cherry pits, and more. Refer to the owner’s manual for fuel specifications unique to your stove.

6.Pellets light.

The combustion blower forces heated air from the igniter into the burn pot or grate to light the pellets. Premium pellets will produce less ash than corn or low-grade pellets.

7.Convection blower begins to run.

Some units may start the convection blower at the same time as the combustion blower. Others wait until the fan temperature sensor reaches a predetermined heat level before starting the convection blower to avoid blowing cold air.

8.Stove runs until signaled to shut off.

The stove will continue to feed and burn more pellets until manually turned off or the thermostat senses the room has reach the desired heat level.
