Drilling the Oven to take the heat sensor
You may now drill the hole to take the oven sensor. It
should be drilled at a 45 degree angle about 20 mm in
from the frame up into the oven. The hole will come out
inside the oven, behind the side wall ( which can be un-
screwed if you wish – 2 ¼” Whitworth bolts hold the side
wall in place)
Don’t drill too close to the frame as it makes removing
the sensor more difficult .
Drilling the Oven Rear Wall to mount the sensor
See diagram . Drill and tap a 6 mm hole . Loosely fit the
clamp, remembering to fit the small insulation pad behind
the clamp.

Front Edge of Frame
Must point forwards
toward the blast tube
The same Frame is used for both the OF7
& OF22 burners, but the positioning is
different ( See photo)
Now fit the burner frame to the burner
assembly
Preparing the Burner
Take a tube of silicone and apply a thick bead all
around the inner face of the burner frame
,
Take the 35mm x 725 mm rope seal part no 1 and
glue into position. Making sure that the ends both
finish equal, just below the burner housing.
FITTING THE CERAMICS
Take the block marked No 2 and fit over the blast tube
and slide tightly down onto the base. It may be
necessary to gently ease the blast tube hole and the
sides to allow the block to slide into position.
