NOTE: Chase Installation: (See Figure 3). A chase is an enclosure built specifically to house a chimney. The
interior of a chase is open from ZC20 to roof, eliminating need to cut through ceilings and roof. Normally, a chase
is built outside and against exterior wall of a home. A hole is cut through wall and the ZC20 is located in bottom of
chase, with front of unit flush with interior wall. Chases are commonly veneered on outside with brick, stone or
wood to give appearance of a conventional fireplace flue. Occasionally, they are built inside and boxed in, similar
to a stairwell. When making a chase installation, it is important to read chimney manufacturer’s instructions prior
to building, as there are specific requirements for bracing a free-standing flue and must be planned for. There are
also occasions where offsets are used within a chase to accommodate unusual building designs or to locate ZC20
further into a room.
FRAMING CONSTRUCTION AND INSTALLATION
Except as noted, ZC20 can be installed almost anywhere you desire. There are, however, a few clearance and
framing restrictions that must be followed. See Figure 3 and 4 to make sure that these clearance restrictions are
met. It is much wiser to place your ZC20 correctly at start of installation than to be forced to relocate it after much
of work is done.
You must ensure that floor is of adequate strength to accept load of this unit. If inadequate, floor will require
additional support, such as bracing. NOTE:
A wooden base constructed of plywood or 2”x4” boards is required in
order to get proper clearance above the extended hearth (millboard, rock, stone, etc.).
Good planning is essential for a satisfactory installation, therefore, at this point you should have decided where
ZC20 is to be located and the route chimney will follow to the roof
—
straight up or chase. If you cannot decide best
route, contact your Dealer for assistance with planning.
Above (Figure 4) are framing location examples with depth dimensions for some typical configurations. These are
finished measurements so install accordingly.
Position ZC20 for installation as follows:
1. Thoroughly clean area where unit will be placed. Remove any carpeting/padding from area where the ZC20
will be installed.
2. Lay out location on the floor for ZC cabinet. (See Figure 4)
3. Lay out for hearth extension preparation and removal of carpet and padding.
4.
A sheet metal safety shield is placed 1 1/2” under cabinet. It must extend out under floor protector.
5. Now, you are ready to install chimney system for ZC20. If you are building an outside chase, follow approved
Chimney Manufacturers instructions. If you are penetrating a ceiling, install the chimney as follows:
a. Drop a plumb line, locate, and mark point on ceiling directly over center of ZC20 chimney adapter.
b.
After locating center of hole, install fire stop spacer per chimney manufacturer’s instructions.
