INSTALLATION
C. VERTICALLY WITH NEW CHIMNEY SYSTEM (Refer
to Figure 10)
NOTE: Follow L-Vent chimney manufacturer’s instructions.
OPTION: To achieve a center vertical installation a 45º el-
bow and a clean-out tee can be used to offset the pipe from
the exhaust outlet to the rear center of the stove.
OPTION: Install L-Vent elbow in place of clean-out tee. Lo-
cate stove. Drop plumb bob to center of tee outlet, mark
point on ceiling. Install ceiling support and L-Vent pipe per
L-Vent manufacturer’s instructions.
1. Always maintain 3” clearance from combustible materi-
als. When passing through additional floors or ceilings,
always install firestop spacer.
2. After lining up for hole in roof, cut either a round or square
hole in roof, always 3” larger all the way around pipe.
Install upper edge and sides of flashing under roofing
materials, nail to the roof along upper edge. Do not nail
lower edge. Seal nail heads with non-hardening water-
proof mastic.
3. Apply non-hardening, waterproof mastic where the storm
collar will meet the vent and flashing. Slide storm collar
down until it sits on the flashing. Seal and install cap.
Mobile home installations must use a spark arrester.
D. VERTICALLY INTO EXISTING CHIMNEY SYSTEM
Adapters are available to adapt from 3” L-Vent to 6” or 8”
Class-A chimney. (Figure 11a)
As an alternative, 3” or 4” L-Vent can be run inside existing
chimney to termination. (Figure 11b)
This is the preferred method.
Follow guidelines for equivalent vent length.
