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 confi 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.

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
