To investigate the suitability of your chimney, contact us, we will be pleased to arrange a site visit. This is very important, because the condition of your chimney will determine how well your stove performs; a poor chimney system will affect its efficiency. Any existing flue must be swept and inspected before installation of the stove. All multi-fuel/wood burners must be installed in a class 1 chimney.
There are many different flue systems available; Dependant on type of stove purchased.
No. All Stoves must be individually flued.
No. The internal diameter of the flue must be no smaller than the appliance flue collar for its entire length. If burning wood on a stove with a 5” outlet a 6” liner must be fitted.

The quality of fuel will dictate the performance of your Stove.
Burn only dry, well seasoned wood. For best results, use dry wood, with moisture content of less than 20%, which has been cut, split and stacked for at least 12 months. This is advertised as ‘seasoned’ wood.
Alternatively you can purchase kiln dried wood from us or www.realfirewood.co.uk
Burning wet or unseasoned wood will create tar deposits in the stove and chimney and won’t produce a satisfactory heat output.
Wood burns best on a bed of ash and it is therefore only necessary to remove surplus ash from the stove occasionally.
Only to be used in turf or brick form, but the moisture content must be very low.
Anthracite is an approved natural smokeless fuel (not processed) but can vary greatly in quality and performance. It generally requires excellent air supply to maintain maximum performance and with experience we would suggest that it is used in conjunction with other approved manufactured smokeless fuels as per the HETAS approved list.
Please visit www.hetas.co.uk for an up to date list of approved Manufactured Smokeless Fuels suitable for closed appliances.
Only authorised smokeless fuels may be used in smoke control areas.
