Wow- Just read the Kodiak 1700 manual online, "stress lines and overfiring" on pages 4 and 8 are interestingly stated. Will def have to check into this lawyer-ese and see if an answer can be gotten.
Is "stress lines" a euphemism for cracks?
Why would they write this into the instructions, unless it's been a problem?
"Stress lines located within the firebox at the secondary air channels
may result from the repeated
expansion and contraction of metal during regular use. These lines, when narrower than the thickness
of a coin, do not compromise the safety or efficiency of the unit and as such do not necessitate repair or
replacement.
Similarly,
stress lines that may appear on the firebox front due to regular use also do not compromise
safety or efficiency of the unit, with the possible exception of the door gasket. In the event that these
extend beyond the door gasket, they may have a minor effect on the integrity of the seal and will then be
covered by the warranty policy for repair.
The term "logs" here is pretty subjective...a "log" can be very big. Then again, they seem to be suggesting that the operator should only add enough wood to last "several hours." What if I want to sleep longer than "several hours?"
"b) DO NOT OVERLOAD THE STOVE.
Normally, three or four logs will provide heat for several hours.
Never operate this stove where portions glow red hot. Using more than five logs at a time can cause
overfiring. Keep logs a few inches from the lowest point of the top of the firebox. If any logs are touching
the tubes in the top of the firebox, you can damage the air tubes. Overloading the stove can cause
damage to the firebox and air tubes and will void the warranty."
It's possible they are just over-stating the whole thing, to scare users into being cautious. I imagine there are more than a few idiots that just burn the living hell out of these stoves. It would be good to know how they are actually handling problems that arise from normal use...
