• where curtains, furniture, clothing, or other am-

mable objects are less than 42" from the front,

top, or sides of the replace

• in high trafc areas

• in windy or drafty areas

5. This replace reaches high temperatures. Keep

children and adults away from hot surfaces to avoid

burns or clothing ignition. Fireplace will remain hot

for a time after shutdown. Allow surfaces to cool

before touching.

6. Carefully supervise young children when they are

in the room with replace.

7. Do not modify replace under any circumstances.

Any parts removed for servicing must be replaced

prior to operating replace.

8. Turn replace off and let cool before servicing, install-

ing, or repairing. Only a qualied service person

should install, service, or repair the replace. Have

burner system inspected annually by a qualied

service person.

9. You must keep control compartments, burners, and

circulating air passages clean. More frequent clean-

ing may be needed due to excessive lint and dust.

IMPORTANT SAFETY INFORMATION

This replace is a vented product. This replace must

be properly installed by a qualied service person. The

glass door must be properly seated and sealed. If this

unit is not properly installed by a qualied service person

with glass door properly seated and sealed, combustion

leakage can occur.

CARBON MONOXIDE POISONING: Early signs of

carbon monoxide poisoning are similar to the u with

headaches, dizziness and/or nausea. If you have these

signs, the replace may not have been installed properly.

Get fresh air at once! Have the replace inspected and

serviced by a qualied service person. Some people

are more affected by carbon monoxide than others.

lung disease or anemia, those under the inuence of

alcohol, and those at high altitudes.

Propane/LP gas and natural gas are both odorless. An

odor-making agent is added to each of these gases. The

odor helps you detect a gas leak. However, the odor

added to these gases 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.

1. This appliance is only for use with the type of gas

indicated on the rating plate. This appliance is not

convertible for use with other gases unless a certi-

• shut off gas supply.

• do not try to light any appliance. Continued on page 4

CDV Series Gas Fireplace PRE-INSTALLATION INFORMATION

FIREPLACE LOCATION

Plan for the installation of your appliance. This includes determining where the unit is to be installed,

the vent conguration to be used, framing and nishing details, and whether any optional accessories

(i.e. blower, wall switch, or remote control) are desired. Consult your local building code agency to

ensure compliance with local codes, including permits and inspections.

The following factors should be taken into consideration:

• Clearance to side-wall, ceiling, woodwork, and windows. Minimum clearances to combustibles



• This replace may be installed along a wall, across a corner, or use an exterior chase. See Figure

6 for suggested locations.

• Location should be out of high trafc areas and away from furniture and draperies due to heat

from appliance.

• Never obstruct the front opening of the replace.

• Do not install in the vicinity where gasoline or other ammable liquids may be stored.

• Vent pipe routing. See Venting section found in this manual for allowable venting congura-

tions.

• These units can be installed in a bedroom. See National Fuel Gas Code ANSI Z233.1/NFPA 54

— (current edition), the Uniform Mechanical Code — (current edition), and Local Building Codes

for specic installation requirements.

* When you install your replace in (D) room divider or (E) at on wall corner positions (Y), a minimum of 4"

clearance must be maintained from perpendicular wall and front of replace.
