lowing guidelines:
1. The location must allow for proper clearances (see Figure 1).
• Flush installation is recommended where
living space is limited.
• Projected installation may be ideal for
a new addition to an existing nished
wall.
• Corner installation makes use of a space
that may not normally be used and pro-
vides a wider and more efcient range
for radiant heat transfer.
2. Consider a location where the replace
would not be affected by drafts, air conditioning ducts, windows or doors.
3. A location that avoids the cutting of joists
or roof rafters makes ventilation installation easier.

location of your replace, you will vent
vertically or horizontally.
4. Allow 1" of pipe to protrude from internal
wall, depending on wall thickness. See
Figure 7, page 11.
5. For horizontal installation, an optional
siding standoff may be installed between
vent cap and exterior wall. Secure horizontal vent cap to standoff. Secure standoff/
vent cap assembly to wall (see Figure 7).
Do not seal termination to vent pipe. Vent
termination must be removable for service
pipe inspection.
6. For vertical installation, a vertical termination is available. A vertical ue restrictor must be installed into inner collar of
replace as shown in Figure 6, page 10.
When installing a length of pipe for vertical
termination that is over 3 ft., support pipe
every 3 ft. using metal wall straps. Vertical
to horizontal pipe must be kept at a 1 ft. to
4 ft. ratio with a maximum run of no more
than 20 ft.
If an offset is necessary in attic to avoid
obstruction, it is important to support vent
pipe every 3 ft. to avoid excessive stress
on elbows and possible separation (see

Note: Vertical restrictor must be installed
in all vertical installations.
1. Determine the route your vertical venting
will take. If ceiling joists, roof rafters, or
other framing will obstruct venting system,
consider an offset (see Figure 13) to avoid
cutting load bearing members.
Note: Pay special attention to these instal-
lation instructions for required clearances
(air space) to combustibles when passing
through ceilings, walls, roofs, enclosures,
attic rafters, etc. Do not pack air spaces
with insulation. Also note maximum
vertical rise of venting system and any
maximum horizontal offset limitations.
2. Set replace in desired location. Drop a
plumb line down from ceiling to position
of replace exit ue. Mark center point
where vent will penetrate ceiling. Drill a
small locating hole at this point.
Drop a plumb line from inside roof to

Glass must be cleaned periodically. During
start-up it is normal for condensation to form
on the inside of the glass causing lint, dust
and other airborne particles to cling to the
glass surface. During initial start-up a slight
lm may form on the glass due to paint curing.
The glass should be cleaned several times
with a non-ammonia, nonabrasive household
cleaner and warm water after the rst two
weeks of operation. Thereafter, clean the
glass two or three times during each heating season, depending on the usage and
circumstances present. Refer to Removing Glass Panel, page 18 of this manual when
removing glass door for cleaning.

LOGS
• If you remove logs for cleaning, refer to
Installing Logs Lava Rock and Glowing
Embers, page 19, to properly replace logs.
• Use a vacuum cleaner to remove any
carbon buildup on logs.
• Replace log(s) if broken. See Replacement
Parts on page 33.
•
Replace ember material periodically
as needed. See Replacement Parts on
page 33.
VENTING SYSTEM
Conduct annual inspection of the venting
system following these guidelines:
1. Check areas of venting system that are
exposed to the weather for corrosion (rust
spots or streaks and, in extreme cases,
holes). Have these items replaced im-
mediately by a qualied service person.
2. Remove the vent cap and shine a ash-
light into the vent. Remove any foreign
material.
3. Check for evidence of excessive con-
densation. Continuous condensation can
cause corrosion of caps, pipes and ttings
and can be caused by having excessive
lateral runs, too many elbows or exterior
portions of the system being exposed to
cold weather.
4. Inspect joints to verify that no pipe section
or tting has been disturbed and loosened. Check mechanical supports such
as wall straps for rigidity.
PILOT AND BURNERS
• Remove ember material before cleaning
burners and replace when cleaning is
complete.
• Burner and controls should be cleaned with
compressed air to remove dust, dirt or lint.
• Use a vacuum cleaner or small, soft bristled
brush to remove excess dust, dirt or lint.
