ODWR Series Outdoor Woodburning Fireplaces
Installing Outside Air Kit
An outside air kit is not installed in all ODWR Fireplac-
es. If desired, or if local codes mandate the use of an
air kit, then an AKU1 is required . If the outside air kit is
to be used, the AKU1 MUST be installed BeFORe the
fireplace is enclosed. Refer to the AKU1 instructions for
field installation.
Installing the Chimney System
Start by attaching the first chimney section to the collar
on top of the fireplace.
Install the pipe as pictured in Figure 17. When you
get a good lock, you will hear the pipe clearly snap
together. Once sections are snap-locked in place, it is
extremely difficult to get them apart. Make sure the
pipe is firmly snapped and locked together as each
pipe section is mounted.
Pipe Section
Fig. 17 Install pipe, listening for the snap-lock to fasten.
When installing elbows, only outer pipe will snap-
lock. Middle pipes simply slide into position. Be sure
to always attach straps on upper elbow to a structural
framing member. (Fig. 18)
Continue installing the pipe as required until pipe is
installed up through the ceiling. At this point, you must
install a firestop spacer.
Installing the Firestop Spacer
in the Ceiling Hole
A firestop spacer is used to keep pipe spaced properly
and required for safety.
Nail the firestop spacer (at each corner) to the framing
members of the ceiling hole. NOTe: A firestop spacer
is not required at the roof.

Hole sizes listed in Figure 13 for angled firestop spac-
ers provide minimum required air space to chimney
pipe for ceiling thickness up to 8" (203 mm). When
combined thickness of ceiling material, ceiling joists and
flooring material exceeds 8" (203 mm), adjustments
must be made in framing to assure that minimum air
spaces to chimney are maintained.
Proper Firestop Spacer Installation
Figure 19 shows different installation procedures for
both an area that is an attic and an area that is not an
attic.
If the area above the ceiling is not an attic, position the
firestop spacer with the flange on the ceiling side and
the angled portion extending up into the hole.
If the area above the ceiling is an attic, position the
firestop spacer with the flange on the top of the framed
hole and the angled portion extending down into the
hole.
Firestop spacers are not available for nor are they
required on vertical walls.
DO NOT put any sealant around the area where the
outer pipe slides through the firestop spacer. If you
seal this area, it may cause a fire hazard.
Canadian Requirements
for Insulation Shield
In Canada, an attic insulation shield is required to pre-
vent attic insulation from contacting the chimney sec-
tion. Framing dimensions for the chimney hole should
measure 14¹⁄₂" x 14¹⁄₂" (368 x 368 mm). An attic shield
MUST be installed on top of attic joists (above the floor
level). (Fig. 20)
