Exhaust Restrictor Installation - Heat & Glo ST-HVBI-AUB Owner's Manual

1.3. Exhaust Restrictor Installation

Exhaust restrictors are recommended for these verti-
cally terminated products which have excessive draft.
Exhaust restrictors will compensate for high draft and
restore visual fl ame height. If the vent confi guration
has a total vertical of 15 ft. - 40 ft. (4.6 m - 122 m)
an exhaust restrictor may be needed. The exhaust
restrictor can be located in the manual bag.
Exhaust Restrictor Instructions:
1. Locate the center vent hole of the air passage
on the inside fi rebox chamber as shown in
Figure 6.
2. Center the exhaust restrictor such that the
center hole of the restrictor aligns with the center
vent hole of the air passage inside the fi rebox
chamber.
3. Use (2) 1/2 in. (13 mm) self-tapping screws to
secure exhaust restrictor to the fi rebox air pas-
sage. See Figure 7.
4. In some applications, such as those that where
the fi replace is elevated off the fl oor, the exhaust
restrictor may be painted but painting is not
required.
NOTICE: Before painting, contact your dealer for
information on the appropriate high temperature
paint.
