LENNOX HEARTH PRODUCTS • MONTEBELLO® SEE-THROUGH DIRECT-VENT GAS FIREPLACES (LSM40ST-N / LSM40ST-P) • CARE AND OPERATION INSTRUCTIONS

PLACEMENT OF VOLCANIC STONE, GLOWING EMBERS, AND LOGS

1.Remove glass door and mesh pull screens from one side of fireplace only (see Page 12 ).

2.Locate materials (log set, bag of glowing embers, and bags of volca- nic stone).

Note: LOGS ARE FRAGILE! Handle with care to prevent breakage.

3.Install volcanic stone. Place some of the volcanic stone on the firebox floor around the grate (the entire bag of volcanic stone will NOT be used).

Note: Do NOT place volcanic stone on burner.

4.Prepare and install glowing embers.

Note: This appliance is provided with enough glowing ember material for several applications. Do NOT use the entire contents of a new bag at one time.

a)Separate some of the glowing ember material into pieces about the size and thickness of a dime (see Figure 9 ). Keep the pieces fluffed up, not matted.

IMPORTANT! Ember pieces must be

as SMALL and THIN as a dime.

b)Distribute the dime-sized pieces over the surface of the burner, in the areas shown in Figures 10 and 11.

Note: To prevent flame impingement and soot, do not use more ember material than necessary.

c) For best glowing effect, replace ember material annually.

Note: Use only catalog number H8312 Glowing Embers with this fireplace.

WARNING

•DO NOT attempt to install the logs until the appli- ance installation has been completed, the gas line connectedandtestedforleaks,andtheinitialburner operation has been checked out.

•Logs get very hot and will remain hot up to one hour after gas supply is turned off. Handle only when logs are cool. Turn off all electricity to the appliance before you install volcanic stone, embers and logs.

•The size and position of the log set was engineered to give the appliance a safe, reliable and attractive flame pattern. Any attempt to use a different log set in the fireplace will void the warranty and will result in incomplete combustion, sooting, and poor flame quality.

•This appliance is not designed to burn wood. Any attempt to do so could cause irreparable damage to the appliance and prove hazardous to your safety.

•If logs are not installed according to the log installa- tion instructions, flame impingement and improper combustion could occur and result in soot and/or excessive production of carbon monoxide (CO), a colorless, odorless, toxic gas.
