SAFETY INFORMATION

This replace is a vented product. This replace
will not produce any gas leakage into your home if
properly installed. This replace must be installed
by a qualied (certied or licensed) service person.
If this unit is not properly installed by a qualied
service person gas and/or carbon monoxide leak-
age (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
inuence of alcohol and those at high altitudes.
Natural and Propane/LP Gas: Natural and propane/
LP gases are odorless. An odor-making agent is
added to these gases.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.

ings. Keep this manual for reference. It is your
guide to safe and proper operation of this heater.

or other accessory not approved
for use with this replace.
WARNING: Do not allow fans

ame patterns. Ceiling fans can
create drafts that alter burner
ame patterns. Altered burner
patterns can cause sooting.
Due to high temperatures, the
appliance should be located out
of trafc and away from furniture
and draperies.

PRODUCT FEATURES
These are a few facts that can help you understand
and enjoy your vented decorative replace:
• The (V)CB36N(E) and (V)CB36P(E) series
of vented decorative replaces may be recessed
into an exterior chase, an interior ush wall
enclosure or a framed-in corner installation.
• Models (V)CB36N and (V)CB36P are
equipped with a millivolt gas control system
that does not require electricity to operate.
A piezo ignitor is provided to light the pilot
without using matches or lighters.
• Models (V)CB36N(E) and (V)CB36P(E) are
equipped with an electronic ignition system
that requires 120 VAC to operate. An electrode
ignitor automatically lights the pilot ame when
the replace is turned on.
• These replaces can accept any approved 4"
B-Type venting system and must be terminated
vertically through the roof using a listed type
vent cap only. See venting instructions starting
on page 8 for proper venting requirements.
• These vented replaces require indoor air for
combustion and must be installed in a room of
sufcient size to provide adequate fresh air for
safe and proper operation. The room intended
for installation must be of sufcient size to
meet the requirements for an unconned space
as dened in the National Fuel Gas Code,
ANSI Z223.1/NFPA 54, Section 5.3, Air for
Combustion and Ventilation. If sufcient air
for combustion is not available a makeup air kit
model AK4 may be required to provide outside
air to this appliance. Check your local codes as
to specic requirements for make up air.
• This replace may be installed in any room of
the house provided all local codes and these
installation instructions are followed.
PRE-INSTALLATION
PREPARATION
LOCATION AND SPACE
REqUIREMENTS
Determine the safest and most efcient location
for your DESA direct-vent replace. Make sure
that rafters and wall studs are not in the way of the
venting system. Choose a location where the heat
output is not affected by drafts, air conditioning
ducts, windows or doors. Figure 2 shows some
common locations. Be aware of all restrictions and
precautions before deciding the exact location for
your replace and termination cap.
When deciding the location of your replace,
follow these rules:
• Do not connect this replace to a chimney ue
servicing a separate solid fuel burning replace
or appliance.
• Do to high temperatures, do not locate this
replace in high traffic areas, windy or drafty
areas, or near furniture or draperies.
• Proper clearances must be maintained.
• If your replace is to be installed directly on
carpeting, vinyl, tile or any combustible mate-
rial other than wood, it must be installed on a
metal or wood panel extending the full width
and depth of the replace (see Figure 3).
• Only trim kits supplied by DESA shall be used
in the installation of this replace, see Acces-
sories, page 34.
• Do not install aftermarket vent dampers.
Manual or automatic vent dampers are not ap-
proved for use with this appliance.
• Your replace is designed to be used in zero
clearance installations. Wall or framing material
can be placed directly against any exterior sur-
face on the back, sides or top of your replace,
except when clearances are required from ue
vent pipe, see Clearances on page 6.
• If recessed into a wall, you can avoid extra
framing by positioning your replace against
an already existing framing member.
