SELECTING LOCATION
To determine the safest and most efcient
location for your replace, consider the fol-
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.

DANGER: Carbon monoxide
poisoning may lead to death!
This replace must be installed by the O.E.M.
builder or by a qualied (certied or licensed)
service person. It has a sealed gas combustion chamber that uses a coaxial pipe (pipe
within a pipe and having the same center)
venting system. It brings in fresh air for combustion through the outer pipe and combustion gases are exhausted through the inner
pipe. If the glass door assembly and venting
pipe are not properly seated, connected and
sealed, carbon monoxide leakage (spillage)
can occur.
Carbon Monoxide Poisoning: Early signs
of carbon monoxide poisoning resemble the
u, with headaches, dizziness or nausea. If
you have these signs, the replace may not
be working properly. Get fresh air at once!
Have replace serviced. Some people are
more affected by carbon monoxide than others. These include pregnant women, people
with heart or lung disease or anemia, those
under the inuence of alcohol and those at
high altitudes.
Propane/LP and Natural Gas: Propane/LP
and natural gas are odorless. An odor-making
agent is added to the gas. The odor helps you
detect a gas leak. However, the odor added to
the gas can fade. Gas may be present even
though no odor exists.
Make certain you read and understand all
warnings. Keep this manual for reference. It
is your guide to safe and proper operation of
this replace.
WARNING: Any change to
this replace or it’s controls can

VENT TERMINATION CLEARANCES
Final position of your replace depends on
location of the vent termination in relation to
clearances that must be observed as shown
in Figure 5 on page 8.
The vent system serves as the “chimney” as
well as combustion air supply (air intake).
The horizontal run must have a rise of 1/4"
(0.6 cm) for every 12" (30.48 cm) of horizon-
tal run towards the termination. Maximum
horizontal run depends on vertical rise from
replace adapter collar to vent termination
(see table below).
VERTICAL HORIZONTAL
0 to 1 ft (30.48 cm)
1 ft (30.48 cm) to 4 ft (121.92 cm)
2 ft (60.96 cm) to 8 ft (243.84 cm)
3 ft (91.44 cm) to 12 ft (365.76 cm)
4 ft (121.92 cm) to 16 ft (487.68 cm)
5 ft (152.40 cm) to 15 ft (457.20 cm)
6 ft (182.88 cm) to 14 ft (426.72 cm)
7 ft (213.36 cm) to 13 ft (396.24 cm)
8 ft (243.84 cm) to 12 ft (365.76 cm)
WARNING: Never allow the
vent to run downward as this
may cause excessive temperatures which could cause a re.
FRAMING
Once the nal location has been determined,
observing height clearances for vent termination, you may construct framing using dimensions shown in Figures 3 and 4, depending on
your installation.
If the appliance is to be installed directly on
carpeting, tile (other than ceramic) or any
combustible material other than wood ooring, appliance must be installed on a metal
or wood panel extending full width and depth
of the appliance.
