CONNECTION TO A MASONRY
CHIMNEY
The Napoleon Model NZ25 may be connected to either a
lined or unlined masonry chimney.
IF THE CHIMNEY
IS LINED,
the flues
must be made of vitri-
fied clay and be in
sizes of 8" square, 8" x
12", or 8" round with a
minimum height of 15
feet above the fire-
place. Eight inch round
flues
are
recom-
mended. Installation
must conform to both
national and local
code requirements.
FIGURE 16
IF THE CHIMNEY IS UNLINED,
liner listed to Standard ULC-S640M: Liners for New Ma-
sonry Chimneys, may be used to connect the fireplace to
the chimney. The liner must be continuous from the fire-
place to the chimney cap and be installed only per manu-
facturers instructions. Figure 16. In both cases, the chim-
ney structure must be supported by angle iron anchored
into the masonry walls. Figure 17. The allowable ma-
sonry used in chimney construction is 3-1/2" brick, solidly
mortared and fully encasing the flue. Ensure there are no
leaks.
FIGURE 17
In no case is the masonry enclosure to be supported by
the NZ25 fireplace. Allow a 1" (one inch) air cavity for
expansion.

FINISHING
FIREBRICK REMOVAL:
The fireplace is shipped with the firebricks in place, how-
ever if you need to remove them (ease of installation, re-
placement, etc), follow this sequence:
Remove the ashwell grate. This allows the bricks to be
removed in the following order--the four bottom bricks, the
bricks along the rear wall (pull the two bricks at the centre,
forward and lift the bottom of the bricks out first), the side
bricks (tilt the top inward).
ATTACHING THE HANDLE:
Attach the handle as shown so that when the door is closed,
the handle will be centred in the slot located on the fire-
place front. To achieve this you may have to experiment (on
the upper and lower screws) with one of the variations
shown. Tighten securely.
