Cracks in the insulation have no effect on the efciency of the stove. The insulation should be replaced,
however, when it is reduced to less than half the original thickness due to wear and tear.
HWAM Autopilot™ (Drawing G)
Lift the top plate off the stove. Remove the rear plate by loosening the two screws. On a cold stove,
the starting point of the feeler is controlled. The starting point for a cold stove is approx. 20° above
horizontal (at laser cut mark).
It should feel easy going and bouncy when you push it, no matter if the stove is cold or hot. By rising or
falling temperatures it must not move at a bound. The damper plates must be dry and clean and slide
together unhindered. Control bars and slide gates may have to be smeared with WD40 (never oil).
Door/glass
A sooty glass door can easily be cleaned with a piece of moist kitchen roll dipped in ash. Go about it in
vertical movements (up and down). Follow up with a dry piece of kitchen roll. Check frequently to ensure
that seals in the door are intact and not brittle. Failing this, they should be replaced. Use original seals only.
Surface
The surface normally requires no treatment. Any damage to the coating may be remedied using a
Senotherm spray.
Guarantee
The guarantee does not cover damage due to insufcient maintenance!
