Installation requirements to replace the first 90º elbow with two 45º elbows:

Figure 7.3

Top Vent - Horizontal Termination

Note: The CD 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

WARNING

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.
