Operation/Care Of Your Appliance - Lennox ED4540CNM-2 Homeowner's Care And Operation Instructions Manual

Do not use these appliances if any part has
been under water. Immediately call a qualified,
professional service technician to inspect the
appliance and to replace any parts of the con-
trol system and any gas control which have
been under water.
Ne pas se servir de cet appareil s'il a été plongé
dans l'eau, complètement ou en partie. Appeler
un technicien qualifié pour inspecter l'appareil et
remplacer toute partie du système de contrôle et
toute commande qui ont été plongés dans l'leau.
Test gage connections are provided on the
front of the millivolt gas control valve (identi-
fied OUT for the manifold side and IN for inlet
pressure. A ¹⁄₈" NPT test gage connection is
provided on the electronic gas control valve
adjacent to the outlet to the main burner.
Minimum inlet gas pressure to these appliances
is 5.0 inches water column (1.24 kPa) for natural
gas and 11 inches water column (2.74 kPa) for
propane for the purpose of input adjustment.
Maximum inlet gas supply pressure to these appli-
ances is 10.5 inches water column (2.61 kPa) for
natural gas and 13.0 inches water column (3.23 kPa)
for propane.
The appliance must be isolated from the gas
supply piping system (by closing its individual
manual shut-off valve) during any pressure test-
ing of the gas supply piping system at test
pressures equal to or less than ¹⁄₂ psig (3.5 kPa).
The appliance and its individual shut-off valve must
be disconnected from the gas supply piping system
during any pressure testing of that system at pres-
sures in excess of ¹⁄₂ psig (3.5 kPa).
These appliances must not be connected to a
chimney or flue serving a separate solid fuel
burning appliance.
Any safety guard or screen removed for servic-
ing the appliance must be replaced prior to
operating the appliance.

sea. If you have these signs, obtain fresh air
immediately. Turn off the gas supply to the
appliance and have it serviced by a qualified
professional, as it may not be operating
correctly.

OPERATION AND CARE OF YOUR
APPLIANCE
Appliance operation may be controlled by the
following means: the factory provided modesty
panel-mounted ON-OFF control switch, a re-
motely located optional wall switch or optional
remote control.
The modesty panel mounted ON-OFF control
switch is located behind the hinged drop-down
panel below the appliance front glass enclosure
panel. See Figure 1.
Gas Controls
The gas controls can be found behind the
hinged drop-down panel.
To open the hinged drop-down panel, actuate the
spring loaded, magnetic catches securing the
door, by gently depressing the outer top corners
of the door until the catches "pop" the door free,
allowing it to swing out and down to open.
On millivolt systems, the piezo ignitor, Hi/Lo
flame adjustment knob, and pilot and main gas
ON/OFF control knob are located on the mod-
esty panel. On both millivolt and electronic
systems the gas valve is located behind the
modesty panel. See Figure 1.
Remove the bottom compartment door by
sliding the hinge pin, located at the door's
left side, to the right until it disengages
from the left corner post hole. Pull the
door diagonally to the left, away from the
fireplace.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Once the control compartment door has been
removed, the modesty panel can be removed
as follows: lift the modesty panel by the tab on
the panel's right end, pull the right end of the
panel away from cabinet and then pull the
panel diagonally out of the corner post slots on
the left side of the unit. Remove the modesty
panel carefully, so that none of the wires
become loose or disconnected. Now complete
access to the gas control valve and its related
controls is attainable.
Operation of millivolt and electronic gas
control systems are different. Before light-
ing and operating your appliance determine
if you have a millivolt or electronic appli-
ance. Refer to Figure 1 for access to the gas
control valve. Millivolt appliances will be
fitted with the gas control valve shown in
Figure 2 on page 4 .
Appliances with electronic systems will be
fitted with the electronic valve shown in Figure
3 on page 4 . Familiarize yourself with the gas
control valve that your appliance uses.

To light millivolt appliances refer to the detailed
lighting instructions found on page 11 (English)
and page 12 (French). Millivolt appliance light-
ing instructions may also be found on the pull
out lighting instruction labels attached to the
gas control valve.
Millivolt appliances are fitted with an ON/OFF
Rocker Switch for appliance ON/OFF control.
See Figure 1 for its location. Once the pilot is
lighted, the ON/OFF rocker switch will control
the appliance ON/OFF operation. To operate:
Toggle the switch between its ON and OFF
positions.
