REMOTE VENTING
The gravity vent system can distribute air to an upper
level or a room next door without an extra blower. If you
use two gravity vent kits you may block off the upper
louver area with the desired facing. The central heat option
allows heat to be sent up to 50 ft. away. Figure 21
illustrates various certified ways of incorporating the two
systems.
THE GRAVITY VENT SYSTEM (FD-V)
The FD-V Kit includes:
- A grille
- A grille adaptor
- A B-vent starter section
- A shut-off damper (do not use with
upper louvers blocked)
IMPORTANT: No substitution of any of these parts is
allowed. These genuine RSF ENERGY parts have the
correct clearances. These clearances must be
maintained for your safety.
The FD-V system incorporates standard 8" B-vent
components for installation. Single wall pipe is not
allowed due to the high temperature of the air in a gravity
vent system. Any listed brand of 8" B-vent pipe may be
used and is not a part of the FD-V. The maximum pipe
length is 15 ft. from the top of the fireplace to the outlet.
The B-vent components can be replaced by UltraBlack
double wall black connector made by ICC only.
NOTE: If two gravity vent lines are installed, then two
FD-V kits must be ordered.
