9.0 MOUNTING THE APPLIANCE (continued)
WARNING
THE WALL WHERE THE APPLIANCE IS TO BE
INSTALLED MUST BE CAPABLE OF LONG-TERM
SUPPORT OF THE TOTAL LOAD OF THE APPLIANCE.
MEASURES SHOULD ALSO BE TAKEN TO ENSURE
SUFFICIENT STRENGTH TO WITHSTAND THE FORCE OF
EARTHQUAKES, VIBRATION AND OTHER EXTERNAL
FORCES.
To ensure customer safety, be sure to design the installation so that the
strength of both the wall and any wall fixings used are sufficient. Lennox
Hearth Products assumes absolutely no responsibility for injuries and
damages that may occur due to improper installation or handling.
The appliance should not be installed until all dry wall sanding and wall
painting has been completed.
Incorrect installation can cause the appliance to fall from the wall and
cause injury. Do not block the ventilation holes of the appliance. The
wall onto which the appliance is installed must be flat. Install only on a
vertical surface. Avoid sloped surfaces. Installation onto anything other
than a vertical wall may result in fire, damage or injury.
A full size fitting template is supplied to assist with wall mounting.
Mark the positions shown as "Fixing Points" on the wall. If the appliance
is to be mounted on the inner leaf of a conventional cavity wall, or a
solid wall, drill four holes using a 1/4" masonry bit. Insert the fiber wall
plugs provided.
If the appliance is to be mounted on a dry lined wall or a timber framed
construction wall then special cavity screw fixings will be required which
are not supplied with this product. These should be constructed from
metal and not plastic.
If a concealed gas connection is to be made ensure the gas supply pipe
is in it's final position and can enter the appliance in the correct position
when the appliance is hung on the wall.
Insert the wall mounting screws into the top wall plugs, taking care to
leave the screws protruding approximately 3/8" from the wall. Now hang
the appliance onto these screws through the two keyhole shaped holes
in the back panel of the appliance.
Insert the lower mounting screws into the lower wall plugs through the
corresponding depressed holes in the lower part of the back panel. Do
not tighten fully.
Before tightening the wall mounting screws fully, at this stage it is
recommended to check the horizontal alignment of the appliance with a
spirit level, as small adjustments can still be made if necessary. When
this has been checked, tighten all four fixing screws fully.
To access the upper fixing screws insert a screwdriver through the
holes in the deflector plates above the catalyst as shown in figure 3.

10.0 CHECKING THE BURNER

There are no imitation fuel bed components to install. The appliance
features a ribbon burner which is designed to produce a continuous
band of flame over its length. The burner should be visually inspected
to ensure it is free from any foreign matter. If it is necessary to clean or
dust off the burner then the glass door should be removed by removal
of the four retaining screws. Re-fit the glass door after cleaning or
inspection, ensuring a good seal.

11.0 CONNECTING A GAS LINE

HOLD HEATER REGULATOR WITH A WRENCH TO
PREVENT MOVEMENT WHEN CONNECTING TO INLET
PIPING.
A qualified gas appliance installer must connect the gas room heater to
the gas supply. Consult all local codes. The installer must provide an
ANSI approved manual shut off valve, flex connector and 3/8" NPT
fitting.
Route gas line using techniques and materials prescribed by local
and/or national codes. Only use pipe of 1/2"or greater size to allow full

gas volume to the gas fireplace. Undue pressure loss will occur if the
pipe is too small. An ANSI approved manual shut-off valve and union
must be installed upstream of the heater within the fireplace cavity
when rigid pipe is used. Ensure that a sediment trap is installed
upstream of the heater (figure 4) within the structure's piping system to
prevent moisture and contaminants from passing through the pipe to
the heater controls and burner. Failure to do so could prevent the heater
from operating reliably. The heater gas inlet connection is 3/8" NPT at
the regulator, located below the burner, in the right hand side of the
heater. When tightening up the joint to the regulator hold the regulator
securely with a wrench to prevent the regulator from moving.
