The Loading Door is equipped with
⅝
"
fi
berglass rope gasket. Check the condi on of the gasket on a
regular basis for signs of wear. Over me the gasket will compress and the door may not seal ghtly. Replace as necessary.
Use the "dollar bill test" to check the Loading Door seal. With the wood heater completely cooled, insert a dollar bill between
the door gasket and the face of the wood heater. Leave half of the bill s cking out, close and latch the door, and tug on the
bill. If the bill slips out easily the gasket needs to be replaced. Repeat the test around the perimeter of the Loading Door.
A gasket kit is available from your High Valley dealer and includes silicone adhesive. Part Number: GSKDOR. Thoroughly
remove all of the old silicone from the Loading Door before installing the new gasket. Silicone will not adhere to old silicone.

The Model 2500 Loading Door has a transparent 5mm ceramic window, sealed with a
fi
berglass gasket,
which permits a view of the
fi
re. The ceramic material has excellent heat resistance and strength characteris cs, but it can be
damaged and/or broken. Cleaning instruc ons are found on
Page 17
. Inspect the ceramic glass regularly for signs of damage.
Never use cleaners that contain chemicals that can damage the cataly c combustor. Some industry sources advocate the use
of a razor blade scraper to remove creosote buildup. If you opt to use this method use extreme care to avoid scratching the
ceramic. Monitor any scratches or defects in the ceramic glass as they can develop into cracks with exposure to heat.
Never
operate the wood heater with cracked, damaged, or broken ceramic glass.
Do not
subs tute 3 mm ceramic glass, tempered
glass, window glass, or similar, under any circumstances. OEM 5mm ceramic glass, cut to size and complete with a new gasket,
is available through your High Valley dealer. Part Number: GLS2500
