OPEL AP
Outside air control
The Opel AP is designed to use outside air for combus-
tion but you may choose to use inside air for combustion
air instead. To do so, open the sliding door on the bottom
inside right of the fireplace (behind the bottom louvers).
Note that the fireplace uses outside air when the handle
is closer to the back of the fireplace and inside air when
it's closer to the front. We recommend the use of out-
side air for combustion.
CHIMNEY
This fireplace is certified for use with 7" ICC Model
EXCEL chimney. The chimney system height from the
top of the fireplace must be a minimum of 12 ft. and a max-
imum of 40 ft.
We recommend that the minimum height be increased by
approximately 1 ft. for every 2000 ft. elevation above sea
level. Every 30° or 45° elbow also increases the mini-
mum height by 1 ft. For example, if you are living 6000
ft. above sea level, your chimney should terminate at
least 15 ft. from the top of the fireplace (12 ft. + 3 ft. for
the 6000 ft.). (See Table 1) for more precise recom-
mended flue heights.
CHIMNEY INSTALLATION
NOTE: The clearance between the chimney and com-
bustible material must be 2" or more. DO NOT fill this
area with insulation.
1. Cut and frame the required holes in the floor, ceiling
and roof where the chimney will pass through. Use a
plumb bob. The rough opening in the framing size
is 13 1/4" square.
2. From below, install a radiation shield in each floor
through which the chimney passes. At the attic level,
install a radiation shield and a storm collar as shown
in (Figure 6).

3. Place the first chimney length on the fireplace.
Secure the chimney length to the fireplace with the
three screws provided.
The chimney must extend at least 3 ft. above its point of
contact with the roof and at least 2 ft. higher than any
wall, roof, or building within 10 ft. of it.
NOTE: If the chimney is higher than 5 ft. above the roof,
it must be secured using a roof brace.
4. Put the roof flashing into place. Seal the joint between
the roof and the flashing with roofing tar. For sloping
roofs, place the flashing under the upper shingles and
on top of the lower shingles. Nail the flashing to the
roof using roofing nails.
If the chimney is enclosed to the roof:
-USA:
use a vented flashing.
-CANADA:
use a vented flashing or a
roof radiation shield (ERRS)
and a regular flashing.
5. Place the storm collar over the chimney and flashing.
Seal it around the chimney with silicone sealer (DO
NOT use roofing tar).
6. Fit the rain cap on the chimney. Secure it tightly in
place.
7. Read the EXCEL Chimney installation manual con-
cerning requirements for supports, bracing, anchors,
etc.
8. The maximum height of chimney that can be support-
ed by the top of the fireplace is 18 feet.
