There a few reasons why this is happening; 1 - Wet wood is being used, we recommend a moisture between 15 - 20%. Excessive moisture in the combustion process prevents the blower from gasifying. 2 - Another reason may be a blockage caused by excessive ash building up somewhere between the loading chamber and the flue outlet. We would recommend letting the blower go out and then completing a full clean. 3 - The final and less common cause is user related and stems from too much attention being given to the blower whilst running. You should only need to go to the blower every couple of hours. Entering the blower too often will exacerbate the problems further interfering with the combustion process.

Yes. As the hot air blower pulls fresh air in which is completely separate from the combustion process, the hot air produced is safe to breathe in and can be used in warehouses or offices. Currently a couple of our customers are doing just that.

Yes, however precautions should be taken to ensure that the generator is suitably sized and has a large enough fuel tank to run easily overnight.

As the blower uses oxygen starvation to control the combustion process, absence of power would mean the blower will simply extinguish itself. Do NOT open the door, opening the door will cause the fire to become lively/ reignite and potentially overheat the blower.

The hot air blowers (25 - 130kW) are all able to be run from a single phase, 13 amp supply for example a 3 pin plug socket or fused spur. We recommend speaking with your local electrician to ensure you have ample supply.

No, the blower can be installed externally but steps should be taken to protect it from direct weather. However we highly recommend fully enclosing the blower on a level surface with the correct ventilation installed as this will improve its efficiency.

It can burn all types of wood including mixed loads of sawdust and off cuts so long as they are dry (between 15 - 20%) and free from any accelerants like creosote, glue, or solvent based products. Note: Burning wood in different formats other than those specified above can have a detrimental impact on the amount of smoke produced when the blower is running and could have an impact on the life span of the blower itself.
