4.0 Permitted Fuels
The quality of the firewood you burn can have a considerable effect on performance of the MYSTIQUE burner.
Moisture content, tree species and log size are the main factors that affects the emissions that are produced by
any wood burner. We recommend that firewood with less than 25% moisture content be used.
If you are cutting your own firewood, only wood that has been air dried in a sheltered, well ventilated stack,
preferably for at least 12 months may be burned in MYSTIQUE. To ensure that the wood has a moisture content
of 25% or less, store it under a roof or protected against heavy rain. If you purchase firewood, buy firewood that
is well seasoned and having moisture level below 25%. We recommend “Good Wood” merchants approved by
your local council.
In any case do not burn coal, driftwood, treated or painted wood, highly resinous wood like “Old Man’s
Pine”, laminated plastics, plywood, chipboard, garbage, flammable fluids such as gasoline, naphtha,
engine oil, refuse, milk cartons, colored or printed paper. Use of such materials will invalidate your
warranty, as this may emit toxic, corrosive and hazardous fumes when burned. They may also cause a
build-up of the toxic gas dioxin, which is damaging to the burner and the environment. Most importantly,
use of such materials will invalidate your warranty.
4.1 Testing Your Wood Moisture
There are number of ways to confirm if wood is dry enough.
- Wood moisture meter is the best way to check the moisture content of the wood fuel. Press the meter tip
into wood firmly into the long side of a split piece of wood and test it. The 15-25% percent moister
content is ideal.
- If you are purchasing firewood, ask for dry seasoned wood and get it tested from your wood merchant.
- Dry wood weighs much less than wet wood.
- Wet wood is hard to light and will emit moisture from the ends while burning.
- Two dry pieces banged together sound hollow, wet pieces sound solid and dull.
4.2 Recommended Log Sizes & Fire Starters
- A packet of matches or lighter
- A packet of firelighters. We recommend green firelighters made of wood waste
- Seasoned firewood about 220~250mm long in various sizes
o (2A) For kindling - 15-16 finely split, dry softwood (total 1.0 kg approximately)
o (2B) For intermediate 1 load – 4 pieces (total 1.2 kg, 300 g each approximately)
o (2C) For intermediate 2 load – 4 pieces (total 2.5 kg, 625 g each approximately)
o (2D) For main load – 3 or more pieces (Total 3.0 kg, 1 kg each approximately)
