6. FREQUENTLY ASKED QUESTIONS
Q. Why is burning unseasoned wood not recom-
mended?
A. • It is more difcult to burn
• Stove glass becomes dirty
• It will increase harmful deposits in the ue,
potentially causing corrosive deposits which
can damage the ue liner.
Q. Why are there different tree type measure-
ments?
A. The electrical properties of wood types vary so
the Valiant Moisture Meter has 4 settings to
give an accurate reading. For general moisture
content and unknown tree/wood type select
the tree type 3.
Q. What is the typical moisture content of freshly
cut wood?
A. This varies according to the variety and the
time of year the wood is cut, but is typically
between 35 and 60%. Always ensure that the
wood is below 20% prior to burning.
Q. Will low battery affect the measurement result?
A. When the battery power is less than 70%-80%,
the measurement will become less accurate.
Replace the battery when the low battery
symbol shows.
