Tips from HETA
Installation must be carried out correctly by an expert
The chimney must be approved. If your chimney is old, it must first be inspected and approved by a chimney sweep.
Never use wet firewood.
Avoid burning milk cartons of pressure-treated wood, magazines and newspapers. These materials give off toxic substances when burnt.
Read the instruction manual. Spend 15-20 minutes on firing up so that both the stove and chimney are sufficiently hot.
Add a little firewood at a time at frequent intervals. If you add too much at a time, you will likely have to turn down the air, which causes a lot of pollution.
Never leave the fire going overnight. This is harmful to the environment, as unburnt gases enter the air through the chimney.
How to light a fire
Make sure the air vent is completely open.
Place three sticks at a perpendicular angle to the hatch at the bottom of the stove. Remember to leave roughly two centimetres between each stick.
Place some smaller sticks on top of the three sticks in the opposite direction. Then place a third layer of even thinner sticks on top of those at a perpendicular angle to the hatch. Continue stacking on more in a similar fashion if desired.
Place some brushwood or very thin sticks and a couple kindling bags or bricks at the very top of the pile.
Set fire to the brushwood or thin sticks and leave the hatch roughly one centimetre open until the flames have taken hold.
Once you have got a fire going, use the stove as normal. Only use secondary air/combustion air and close everything else: the hatch, primary air, valve, ash drawer, etc., so that air is only entering the stove from the top of the hatch/glass.
If the pane or stones begin to blacken, it is because the stove is not getting enough air.
All common types of wood are suitable to be burned. Firewood should be cleaved and laid out to dry for 1-2 years under a shed roof to obtain a moisture content of no more than 18 per cent. Keep in mind that firewood will absorb moisture during the winter period. All types of wood have almost the same heating value per kilo. Oak and beech wood is heavy and therefore has higher heating value per cubic metre. Pine wood is light and therefore has a smaller heating value per cubic metre.
How to maintain your stove
Stoves with surface-treated heat-resistant varnishes
You can wipe the stove with a damp cloth. Repair any light damage with repair paint spray.
If your wood is not sufficiently dry, the combustion temperature will be too low. The wood will smoulder instead of burn, leaving soot on the glass. You can clean the glass with any ordinary window glass cleaner or a special glass cleaner from your HETA retailer.
Repair and cleaning of soapstone
Soapstone is a relatively soft natural product. You can therefore repair any scratches or other surface damage with fine sandpaper (grain 120). However, use with caution.
You can clean off soot, grease, etc. with water and a cleaning agent such as brown soap.
· Apply the soap to the surface
· Leave it to work for a few minutes
· Wash off the surface with hot water
· Once the surface is dry, you can sand it lightly with fine sandpaper if needed
If a piece has fallen off your stove, you can glue it back on with water glass, which you can buy at your HETA retailer.
· Apply the water glass to both surfaces where you want to re-apply the piece that has fallen off.
· Keep the piece in place for 24 hours.
· Sand with sandpaper, grain 120.
If a piece has gone missing, or the chipped area is too deep, you can repair the damage with a mixture of soapstone powder and water glass, which you can buy at your HETA retailer.
· Mix the powder and water glass to a suitable consistency.
· Remove any dust.
· Brush on water glass to ensure good adhesion.
· Apply plenty of the soapstone mass, as it shrinks when it hardens. You can continue to apply more if necessary.
· After 24 hours have passed, you can sand the hardened surface. Start by using grain 60-80 sandpaper and finish with grain 120 sandpaper.
