Combustion Technology
Our beautiful and efficient fire is the result of the TruHybrid™ system.
1 – Primary combustion is the burning of the solid fuel, seen as flames on and around the wood.
2 – Secondary combustion is the burning of the gases the wood gives off, visible as flames dancing above the wood, below the baffle.
3 – Tertiary combustion takes place in the catalyst. Any remaining dust and gases are burned before going up the chimney.
There are only 2 controls involved in burning our fully adjustable catalytic wood stoves. Once you understand what each control does, it’s a simple operation.
- Adjust the fire using the air control
- The air control allows you to regulate the amount of air entering the firebox.
- Open the air control to allow more air into the firebox, making the stove burn faster and hotter. Always fully open the air control when starting a fire.
- Close the air control to allow less air into the firebox, making the stove burn slower.
- The air control is usually located below the ash lip. Look in the owner’s manual for each product to verify how to open and close the air control. Some move left-to-right, some are push-pull.
- Engage the catalyst using the bypass handle
- Start the stove with the bypass handle in the bypass position. This allows the smoke to flow up the chimney without passing through the catalytic combustor.
- Engage the catalyst when the stove is up to temperature.
- As the stove heats up, check the catalyst probe, which measures the temperature inside the stove. When the needle reaches the ‘catalyst active’ zone, turn the bypass handle in the ‘engage catalyst’ direction. Your stove is now in its cleanest and most efficient operating mode.
- The plate behind the handle indicates which direction to engage or bypass the catalyst.
- When you add more wood to the fire, momentarily move the handle to ‘bypass’ to keep smoke from coming into the room.
- You can leave the catalyst engaged throughout long, slow overnight burns even though the temperature will eventually drop out of catalytic range.
- The bypass handle is usually located on one side of the stove.
Our Catalysts
The TruHybrid™ System promotes longer catalyst life and fewer maintenance concerns than other catalytic wood burning products.
Catalyst position: Our catalysts are positioned above and away from the front of the baffle. They are positioned after the primary and secondary combustion, so they are always working on pre-cleaned exhaust. They are also protected from direct flame from the fire.
Catalyst operating temperature: Our catalysts operate at temperatures between 1200 ̊ – 1400 ̊F, which is lower than traditional wood stove catalysts.
Catalyst construction: Our catalysts are made from sheets of coated stainless steel. They are designed to expand and contract through the cycles of operation indefinitely.
