The linear spill switch should be attached to the upper
right-hand side on the draft hood diverter (see figure D),
on the Model 425HN and 125HX the linear spill switch
should be attached to the upper left-hand side of the
draft hood diverter. There are two holes provided for
attachment on this diverter and only the front most hole
should need to be used. With the provided #12 self
tapping sheet metal screw securely mount the spill
switch bracket to the diverter. For ease of access
position it so the reset button faces outward and then
bend the bracket so the switch can stand vertically.
The copper capillary sensing tube should then be di-
rected to the opposite end of the draft hood diverter, by
laying it in front of the 5" diameter vent pipe opening, and
down the other side of the draft hood diverter.
