Exhaust restrictors are recommended for these verti
-
cally terminated products which have excessive draft.
Exhaust restrictors will compensate for high draft, and
restore visual flame height. If the vent configuration has
a total vertical of 10-60 feet, an exhaust restrictor may
be needed. The exhaust restrictor can be located in the
appliance manual bag.
