A. Primary air which is the only adjustable combustion air flow for short burn periods to bring the Ecco Stove up to design temperature for optimum performance.
B. Secondary Air in for pre heating for glass cleaning and rolling flame pattern.
C. Gasification System- Tertiary air in for pre heating to burn gasses rather than wood
Flue centre from rear of stove for 678 + 850 is 115mm being 4½” 580 and 730 is 143mm 55/8”

How it works

  1. Air is drawn into the ash pit (primary air) to rapidly heat the mass up to minimum 150ºC being 302ºF top
    centre (ideally 200ºC being 392ºF). When catalysing begins within the firebox.
  2. Flue gas is then deflected by a baffle system toward band b simultaneously for clean glass operation and turbulence within the combustion process.
  3. Gasification takes place via tertiary air introduction for cleanest combustion after which flue gas passes through the appliance via double pass contraflow flue ways to absorb as much heat from the flue gas before exiting to atmosphere.
More Information

    1. Primary Air – Cold air in.

 

    1. Secondary air – Pre-heated air for clean glass operation.

 

  1. Tertiary air – Pre-heated for final re-burn within fire chamber for clean exhaust gases

The multitude of flue ways within the Ecco Stove extract almost all heat from the gas before exhaust to atmosphere.
