To replace the rst starter elbow with two 45° elbows,
refer to Figure 7.4. All other 90° elbows can be replaced
with two 45° elbows.
General Rules:
SUBTRACT 3 ft. from the total H measurement for each
90° elbow installed horizontally.
SUBTRACT 1-1/2 ft. from the total H measurement for
each 45° elbow installed horizontally.
A maximum of three 90° elbows (or six 45° elbows)
may be used in any vent con guration. Some elbows
may be installed horizontally. See Figure 7.9.
Elbows may be placed back to back anywhere in the
system as long as the rst 90° elbow is a starter elbow
except as shown in Figure 7.4.
When penetrating a combustible wall, a wall shield
restop must be installed.
When penetrating a combustible ceiling, a ceiling
restop must be installed.
Horizontal runs of vent do not require vertical rise;
horizontal runs may be level.

1. Top Vent - Horizontal Termination
Note: The CD series appliances can adapt to SLP series
vent pipe when venting off the top of the appliance.
You must use a DVP-SLP24 adapter which can only
be attached to the appliance starting collar.
When looking at horizontal termination diagrams, the
adapter is not counted as part of the minimum vertical
(V
1
min.) requirements.
Whether horizontal or vertical termination, the adapter is
counted as part of the maximum vertical limitations.
All venting rules for the vent run must still be followed.

You may install a DVP elbow directly on top of the

section prior to the elbow.
