Lennox Hearth LBV-4324MN-H, LBV-3824EN, LBV-4324MP-H manual Operation And Care Of Your Appliance

Test gage connections are provided on the front of the millivolt gas control valves (identi- fied OUT for the manifold side and IN for inlet pressure side for both SIT and Honeywell equipped appliances. 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 the appliance is

5.0inches water column (9.5 MmHg) for natural gas and 11 inches water column (20.55 MmHg) for propane for the purpose of input adjustment.

Maximum inlet gas supply pressure to the appliance is 10.5 inches water column (19.95 MmHg) for natural gas and 13.0 inches water column (24.25 MmHg) 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 pressures 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.

WARNING: FAILURE TO COMPLY WITH THE INSTALLATION AND OPERATING IN- STRUCTIONS PROVIDED IN THIS DOCU- MENT WILL RESULT IN AN IMPROP- ERLY INSTALLED AND OPERATING AP- PLIANCE, VOIDING ITS WARRANTY. ANY CHANGE TO THIS APPLIANCE AND/ OR ITS OPERATING CONTROLS IS DAN- GEROUS.

OPERATION AND CARE OF YOUR APPLIANCE

1.Appliance operation may be controlled through a remotely located optional wall switch. Separate switches may provide independent control for the remote controlled fireplace op- eration (optional equipment). In lieu of remote or remote wall switch operation, the appliance must be operated directly through the controls located on the front of the valve located within the control compartment under the removable refractory access panel, Figure 1.

Operation of millivolt and electronic gas con- trol systems are different. Before lighting and operating your appliance determine if you have a millivolt or electronic appliance. Refer to Figure 1 to access the gas control compart- ment below the lower refractory panel.

Millivolt appliances will be fitted with one of the two gas control valves shown in Figure 2 on page 4. Appliances with electronic sys- tems will be fitted with the electronic valve shown in Figure 3 on page 4. Familiarize yourself with the differing controls for the valve your appliance uses.

To light millivolt appliances refer to the de- tailed lighting instructions found in both En- glish and French on pages 10 and 11 of these instructions respectively. Millivolt and elec- tronic appliance lighting instructions may also be found on the pull out rating plate located within the gas control compartment. Refer to Figure 2 for the spark ignitor location used with your appliance.

If your appliance is equipped with an optional remote wall switch or remote control kit the appliance main burner may be turned on and off with the wall switch or remote control. If the appliance is not equipped with a wall or remote control, the main burner must be turned off and on with the gas control knob. Turn the knob counter-clockwise from the PILOT position to ON to light the main burner, and clockwise from ON to PILOT to turn off the main burner.

To light electronic appliances refer to the detailed lighting instructions found in both English and French on pages 12 and 13 of these instructions respectively. Millivolt and electronic appliance lighting instructions may also be found on the pull out rating plate located within the gas control compartment.

If your appliance is equipped with an optional remote wall switch or remote control kit the appliance main burner may be turner on and off with the wall switch or remote control. If the appliance is not equipped with a wall switch or remote control, the main burner must be turned off and on with the gas control switch. Toggle the switch from ON to OFF to operate the main burner from ON to OFF.
