We have just had a minor gas explosion/back puffing in our Pyroclassic. Why has this happened?
This could be caused for the following reasons:
- Rake not used to bring hot char forward causing wood to burn at the wrong end. Use the rake as per Operating Instructions.
- The Turboslide was not opened after re-loading large, cold logs.
- The burning of an explosive substance - battery, aerosol container, etc. DO NOT DO THIS!
- There was an insufficient bed of coals to ensure adequate ignition of a fresh fuel load.
- Too high moisture content of wood fuel. Split one of your logs in half and use your moisture meter to test the wood.
As a point of caution you should never insert a fresh log which is too large or placed in the fire too late to ensure a flaming combustion, doing this will cook the wood fuel on the remaining embers releasing unburnt volatile gases into the combustion chamber which will eventually reach a point of ignition, this can result in a sizable explosion inside the fire chamber and may cause damage to the unit.
