Step 12 Reinstall Front Glass Door; Step 15 Install Wall Thermostat; Step 16 Check Appliance Operation - Lennox EVB125 Installation Instructions Manual

VERIFY THAT THE GAS LINE HAS BEEN PURGED
OF AIR (See Step 10).
Step 12. REINSTALL FRONT GLASS DOOR
ASSEMBLY.
To reinstall glass door assembly panel, reverse
instructions on Step 5, page 9.
Step 13. TEST ALL CONNECTIONS FOR
LEAKS (FACTORY AND FIELD).
A. Mix a 50% dish soap, 50% water solution
(or use a gas leak detection solution).
B. Light the appliance (refer to the lighting
instructions provided in the insert control
compartment and the Homeowner's Care and
Operation Instructions).
C. Brush all joints and connections with the
soapy water or leak detection solution to check
for leaks. If bubbles are formed, or gas odor is
detected, turn the gas control knob to the "OFF"
position and close the gas shut-off valve. Either
tighten or refasten the leaking connection and
retest as described above.
D. When the gas lines are tested and leak free,
observe the individual tongues of fl ame on
the burner. Make sure all ports are open and
producing fl ame evenly across the burner. If
any ports are blocked, or partially blocked,
turn off unit, allow it to cool, then clean out
the ports.
Step 14. INSTALL SURROUND KIT OR CON-
TROL KIT (see pages 11 & 12 in Homeowners
Manual).
Step 15. INSTALL WALL THERMOSTAT AND
REMOTE CONTROL (if purchased)
If an optional Wall Thermostat or Remote
Control Kit was purchased, intall it now, per
instructions provided in kit. See Figure 31. I
wall-mounted thermostat is selected, mount
it in a convenient location on a wall near the
insert. Wire the thermostat within the millivolt
control circuit using a maximum of 25 feet of
18 gage, 2 conductor wire. Caution: Do not
connect the optional wall thermostat, gas
control valve or control wiring system of the
unit to a 120 volt power supply (residential
line voltage).
