Exhaust restrictor Instructions
Exhaust restrictors are recommended for these vertically
terminated products which have excessive draft. Exhaust
restrictors will compensate for high draft, and restore vi-
sual flame height. If the vent configuration has a total
vertical of 20-50 feet, the included exhaust restrictor may
be needed.
Exhaust restrictor: CRAVE4836-B, CRAVE6048-B,
CRAVE7260-B, CRAVE8472-B
1. Locate the two pilot holes in the inside firebox cham-
ber as shown in Figure 4.9.
2. Break the flue restrictor into two pieces. Do this by
bending the part back and forth until it breaks. See
Figure 4.10.
3. The setting for CRAVE4836-B, CRAVE6048-B,
CRAVE7260-B and CRAVE8472-B is 2-2. Align the
holes marked "2" on the numbered exhaust restric-
tor piece with the hole on the other exhaust restrictor
piece. See Figure 4.11. Align the exhaust restrictor
pieces with the pilot holes in the inner firebox cham-
ber. Use two 1/2 inch self-piercing screws to secure
vent restrictor to firebox heat shield.
4. In some applications, such as those where the fire-
place is elevated off the floor, 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.

pilot holes for the exhaust restrictor in the firebox chamber.
2. The setting for CRAVE4836ST-B, CRAVE6048ST-B,
CRAVE7260ST-B, and CRAVE8472ST-B is a 2.5 inch
setting, or 2-2. Align the holes marked "2" on the
numbered exhaust restrictor piece with the hole on
the other exhaust restrictor piece. See Figure 4.11.
Center the exhaust restrictor on the vent and secure
in place with two 1/2 inch self-piercing screws.
