C) Vertically Into Existing Chimney System; D) Vertically Into Existing Masonry Fireplace - Drolet ECO-65 Owner's Manual

c) Vertically into existing chimney system

(Refer to Figure 14)
As an alternative, 4" Vent can be run inside existing chimney to termination (Figure 12). This is the preferred
method.
Follow guidelines for equivalent vent length.

d) Vertically into existing masonry fireplace

(Refer to figure 15)
NOTE: Follow Vent
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 13.
4. Attach the adapter, a section of pipe and cleanout
tee, making sure the cleanout 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.
