Quadra-Fire 4-Point Combustion System

How Does Four-Point Combustion Work?

Maximum efficiency and a cleaner burn. One fire becomes four times more efficient with Quadra-Fire’s patented Four-Point Combustion System. Its secondary burn process burns the smoke within four distinct zones of the firebox, which equals cleaner air, less chimney maintenance and fewer trips to the woodpile.

Here’s how this process really works:  

1. Air flows into the heart of the fire.
2. Shield of air behind the door aids combustion and keeps glass clean.
3. Superheated air ignites flammable gases rising from the wood.
4. Remaining impurities are burned above the baffle before they can escape up the chimney.
