NOTE
Clearance holes in the 5" (127mm) fl ue plate cover
may not align perfectly with the original pilot holes
in rear face of the rear panel. There is adequate
clearance between the oil furnace fl ue and the fl ue
exit hole in the rear panel to accommodate any
misalignment between the two caused by standard
fabrication tolerances. Providing the gap between
the fl ue and the rear panel is completely sealed
by sandwiching fi bre gasket between the two. It is
permissible to drive new holes into the rear panel
using self drilling screws.

WHEN CONFIGURING A HMF150/200 FURNACE WITH THE OIL FURNACE MODULE, IT IS ABSO-
LUTELY IMPERATIVE THAT THE OIL FLUE HEAT SHIELD IS INSTALLED CORRECTLY TO MAINTAIN
CLEARANCES BETWEEN OIL FLUE AND COMBUSTIBLE FLOOR.
