Lennox Hearth Shoreline 33/40 DV INS - Manual (Page 9)

NOTE: DIAGRAMS AND ILLUSTRATIONS ARE NOT TO SCALE
WARNING
THIS FIREPLACE HAS BEEN ALTERED TO
ACCOMMODATE A FIREPLACE INSERT AND
SHOULD BE INSPECTED BY A QUALIFIED
PERSON PRIOR TO RE-USE AS A
CONVENTIONAL FIREPLACE.
Fireplace Requirements
These heaters are designed to be installed into an existing masonry
fireplace (built to UBC 37 or ULC S628 standards) or factory built solid
fuel, wood burning fireplace (listed to UL 127 or ULC S610) only. All
exhaust gases must be vented outside the structure. Combustion air
is drawn from outside the structure. When installing in a factory built
fireplace, the fireplace grate must be removed and the damper must be
removed or secured open.
The insert is designed to fit into a fireplace with a minimum firebox
height of 21-1/2 inches (546 mm). To facilitate this the hood will need to
be removed and discarded (Note: the screws should be replaced in the
insert body). The air intake on the Shoreline™ is removable for easier
installation.
If the factory-built fireplace has no gas access hole(s) provided, an access
hole of 1-1/2 inches (38 mm) or less may be drilled through the lower
sides or bottom of the firebox in a proper workmanship like manner. This
access hole must be plugged with a non-combustible insulation after the
gas supply line has been installed. The installer must mechanically attach
the marking supplied with the gas fireplace insert to the inside of the firebox
of the fireplace into which the gas fireplace insert is installed.
IMPORTANT: When installing these appliances into a factory built fireplace
or heat-form, the air flow within and around the fireplace shall not be
altered by the installation of the insert (i.e. DO NOT BLOCK louvers or
cooling air inlet or outlet ports, circulating air chambers in a steel fireplace
liner or metal heat circulator).
CAUTIONS
• The fireplace in which this gas insert is to be
installed must be thoroughly cleaned if it has
been used to burn wood or synthetic logs. Have
the chimney and all inside surfaces of the fire-
place brushed and vacuumed so that no soot,
embers, or loose combustion deposits can be
drawn into the heat circulation blower and blown
into the living area.
• If any portion of the chimney system shows signs
of structural or mechanical weaknesses, such
as: cracks, leaky joints, corroded or warped
surfaces, the faulty portion must be repaired
or replaced prior to installing this appliance.
• The factory built firebox must accept the insert
without modification other than removing bolted
or screwed together pieces such as baffles /
smoke shelf / deflectors, ash lips, glass door,
screen or door tracks, log grates, refractory or
masonry lining and damper assemblies. Any
fireplace component, which is removed, must be
retained so they can be reinstalled to restore the
fireplace to its original operating condition. The
removal of any part must not alter the integrity
of the outer shell of the pre-engineered fireplace
cabinet in any way. Any parts removed must be
replaceable. If any components are removed
from (or altered) from the existing fireplace, a
Warning Label (see Figure 5) must be affixed
inside the fireplace firebox, so that it shall be
visible upon removal of the fireplace insert. Note:
RTV high temperature silicone is an approved
adhesive to affix the label.
