(a) Select and Attach the Flue Restrictor
WARNING: For proper and safe operation, the correct restrictor
must be installed where required. Measure the restrictor before
installing to be certain of the correct size.
There are four restrictors (rectangular pieces of sheetmetal from 1" to 2-3/4"
wide and 6" to 7-3/4" long) included in your option package. The flue restrictor
which controls the volume of dilution airflow through the drafthood and vent
pipe must be installed on units where required to maintain safe and efficient
operation.
Using the chart on the right, determine
whether or not a restrictor is required, and
if so, which one to use. Select the appro-
priate restrictor from the option kit. On
the inside of the adapter assembly (See
FIGURE 4A or 4B), position the restrictor
across the flue opening. Attach the restric-
tor using two sheetmetal screws.

(Applies to all sizes except
Size 125; see FIGURE 4B.)
NOTES:
• The flue adapter assembly
for a Size 125 is not the
same as illustrated here;
see FIGURE 4B, page 4.
• Heaters manufactured
prior to 10/89 have a fixed
vertical vent outlet. If the
heater being serviced has
a fixed vertical vent outlet,
install the adapter assembly
with restrictor attached over
the fixed vent outlet.
Line adapter
up with these
two holes
when marking
for holes to
drill.
(See instructions
on page 4.)
Holes for attaching restrictor
(Attach the restrictor on the inside
before installing
the flue adapter assembly.)
