Top Vent - Horizontal Termination
Note: The DBDV36PLATI/DBDV42PLATI series fireplaces
can adapt to SLP series vent pipe, if desired.
When venting off the top of the unit, use a DVP-2SL adapter
and a minimum 48 inch vertical section of SLP series vent pipe.
A DVP-SLP24 adapter may also be used with a 24 inch
vertical section of SLP series vent pipe.
After the 48 inch vertical section, the venting table rules
must be followed. The first 48 inch vertical section is NOT
counted as part of the vertical components in the table. It is
still counted as part of the overall maximum run. All venting
table rules for the vent run must still be followed.
Example: DVP pipe 1 ft. min. vertical = 6 ft. max. horizontal
SLP pipe 5 ft. min. vertical = 6 ft. max. horizontal
WARNING
Fire Risk. Explosion Risk.
Do NOT pack insulation or other combustibles
between ceiling firestops.
• ALWAYS maintain specified clearances around
venting and firestop systems.
• Install wall shield and ceiling firestops as speci-
fied.
Failure to keep insulation or other material away
from vent pipe may cause fire.
WARNING
Fire Risk.
• When using DVP-HRC-SS or DVP-HRC-ZC-SS
termination caps on top vented fireplaces, a 6
inch minimum vertical vent section is required
before installing first elbow.
