the vent configuration to be used, framing and finishing details, and whether any optional acces-
sories (i.e. 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
must be maintained.
• This fireplace may be installed along a wall, across a corner or use an exterior chase.
• Location should be out of high traffic areas and away form furniture and draperies due to heat
from appliance.
• Never obstruct the front opening of the fireplace.
• Do not install in the vicinity where gasoline or other flammable liquids may be stored.
• Vent pipe routing. Refer to Venting section found in this manual for allowable venting configura-
tions.
