V entilator Glass Replacement
1. Using an oil can or similar means, squirt
prepsol on the glass filler all around the glass channel or
fram e to soften the old seal. W hen the seal has softened,
remove the glass from the channel.
2. Thoroughly clean the inside o f the glass channel
with sandpaper, rem oving all rust, etc.
3. Using new glass channel filler, cut the piece to
be installed two inches longer than necessary for the
channel. Place this piece o f filler (soapstoned side o f
filler away from glass) evenly over the edge o f the glass
which will fit in the channel. The extra filler extending
beyond the re a r edge of the glass should be pinched
together to hold it in place during glass installation.

roll) is soapstoned. This is the side which goes into
the metal channel.
