Ventilator Glass Replacement

1. Using an oil can or similar means, squirt prepsol or
equivalent on the glass filler all around the glass
channel or frame to soften the old seal. When the
seal has softened, remove the glass from the channel.
2. Thoroughly clean the inside of the glass channel with
sandpaper, removing 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 of filler (soapstoned side
of filler away from glass) evenly over the edge of the
glass which will fit in the channel. The extra filler
extending beyond the rear edge of the glass should be
pinched together to hold it in place during glass
installation.
One side of this filler (the outside of
NOTE:
the roll) is soapstoned. This is the side which
goes into the metal channel.
4. Brush the inside of the metal glass channel freely
with ordinary engine oil. This will enable the glass
and filler to slide freely into the channel. Push the
glass with the filler around it into the channel until
it is firmly seated. After the glass is firmly in place,
the oil softens the filler, causing it to swell, thereby
making a perfect, watertight seal. Trim off the ex­
cess filler material around the channel and at the
ends of the channel.
Glass should be installed so that rear
NOTE:
edge is parallel to the division post. Allow full
cure before water testing.
