V = 3 ft Min. (1m), 50 ft. Max. (15.2 m)
Top Vent - Vertical Termination
No Elbows
Note
: Use DVP Series
components only.
Exhaust restrictors are recommended for these vertically
terminated products which have excessive draft. Exhaust
restrictors will compensate for high draft, and restore vi-
sual
fl
ame height. If the vent con
fi
guration has a total ver-
tical of 20-50 feet, an exhaust restrictor may be needed.
The exhaust restrictor can be located in the appliance
manual bag.

fi
re-
place is elevated off the
fl
oor, the vent restrictor may
be painted, but painting is not required.
5. Recommended restrictor usage:
20 to 30 ft. = 4 inch restrictor
30 ft. and up = 3 inch restrictor
Exhaust restrictor Instructions
1. Locate the two pilot holes in the inside
fi
rebox cham-
ber as shown in Figure 4.9.
2. Center the exhaust restrictor such that the thru holes
in the vent restrictor align with the pilot holes in the
inner
fi
rebox chamber.
3. Use two 1/2 inch self-piercing screws to secure vent
restrictor to
fi
rebox heat shield. See Figure 4.9.
