INSTALLATION

B.VERTICALLY WITH NEW CHIMNEY SYSTEM (Refer to Figure 7)

NOTE: 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 8a)

As an alternative, 3” or 4” L-Vent can be run inside existing chimney to termination. (Figure 8b)

This is the preferred method.

Follow guidelines for equivalent vent length.

D.VERTICALLY INTO EXISTING MASONRY FIREPLACE NOTE: Follow L-Vent chimney manufacturer’s instructions.

1.Have the masonry chimney inspected by a qualified chimney sweep or installer to determine its structural condition.

2.You will need a pipe length equal to the chimney height from the hearth. If outside combustion air is to be used, you will need a pipe length equal to the chimney height plus 18 inches.

3.Install a blanking plate and the chimney pipe, and if used the outside air pipe, as shown in Figure 9.

4.Attach the L-vent adapter, a section of pipe and clean out tee, making sure the clean out tee is centered in the chimney flue area. Use RTV, metallic tape, and a minimum of three self- taping screws at all joint connections to ensure a tight seal.

5.Position the stove, adhering to the clearances in Figures 1 & 2.

6.Measure and build chimney top plate. Cut out holes for chimney pipe, and if used the outside air pipe. Install and seal with non-hardening mastic to prevent water leakage. Install vent cap.
