B. VERTICALLY WITH NEW CHIMNEY SYSTEM (Refer to
Figure 10)
NOTE: See “VENTING” and follow L-Vent chimney manufacturer’s
instructions.
OPTION: To achieve a center vertical installation a 45º elbow 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. Locate
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 materials.
When passing through additional floors or ceilings, always
install firestop spacer.
2. After lining up for hole in roof, cut either around 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 waterproof 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.
C. 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.
