WARNING! Risk of Fire! Maintain specified air space
clearances to appliance and vent pipe:
• Insulation and other materials must be secured to
prevent accidental contact.
• The chase must be properly blocked to prevent blown
insulation or other combustibles from entering and
making contact with fireplace or chimney.
• Failure to maintain airspace may cause overheating and
a fire.
Note: If the inside of the framed cavity is to be finished,
the framing dimensions must include the finished surface.
Example: If drywall is to be attached to the rear wall, the
depth must be measured from the drywall surface.
Note: The appliance must be raised 1 1/4 in. (32 mm) off floor so
the Harbor System can be used. Adjust framing and vent locations
accordingly.
NOTICE: Install appliance on hard metal or wood surfaces
extending full width and depth. DO NOT install directly on
carpeting, vinyl, tile or any combustible material other than
wood.
