F. Vent Diagrams
General Rules:
• SUBTRACT 3 ft. from the total H measurement for each
90º elbow installed horizontally.
• SUBTRACT 1-1/2 ft. from the total H measurement for
each 45º elbow installed horizontally.
• A maximum of three 90º elbows (or six 45º elbows) may
be used in any vent configuration. Some elbows may be
installed horizontally. For example, see Figure 4.18.
• Elbows may be placed back to back anywhere in the
system.
•
Any 90º elbow may be replaced with two back to back
45º elbows.
• When penetrating a combustible wall, a wall shield
firestop must be installed.
• When penetrating a combustible ceiling, a ceiling firestop
must be installed.
• Horizontal runs of vent do not require vertical rise;
horizontal runs may be level.
• Horizontal termination cap should have a 1/4 inch
downward slant to allow any moisture in cap to be
released. See Figure 4.9.

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 and DVP-HRC-ZC-
SS termination caps on top vented fireplaces, a
6 inch minimum vertical vent section is required
before installing first elbow.
Note: The 6000/8000 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 3 ft. min. vertical = 11 ft. max. horizontal
SLP pipe 7 ft. min. vertical = 11 ft. max. horizontal
