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

GENERAL INFORMATION

The ﬁreplace models covered in this manual are direct-vent, sealed combustion, gas ﬁreplaces designed for residential application. Direct-vent appliances operate with the combustion chamber completely isolated from the indoor environment.

All air for combustion is brought in from the outside, and exhaust gases are vented through the same direct-vent, coaxial (intake/exhaust) vent system.

These appliances are designed to operate on natural or propane gas. The system is switchable between standing and intermittent pilot modes. External electrical power is required to operate these units. If the system operates on line voltage, four (4) "AA" batteries (in receiver) can be used as a backup in case of a power outage.

These models come standard with a remotely modulated gas valve. The included transmitter remotely controls ﬂame appearance and heat output (manual gas valve adjustment is not possible).

These appliances comply with National Safety Standards and are tested and listed by Intertek (Report No. 100326523PRT-001) to ANSI Z21.88 (in Canada, CSA-2.33), and CAN/CGA-

2.17-M91 (CSA P4.1) in both USA and Canada,

as vented gas ﬁreplace. The installation must conform to local codes or,

in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 - latest edition, or the Natural Gas and Propane Installation Code, CAN/CSA-B149.1 - latest edition. The appliance, when installed, must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70 - latest edition, or the Canadian Electrical Code, CSA C22.1 latest edition.

Remote Control System

The Remote and Receiver allows you to command the functions of your ﬁreplace from the comfort of your chair. It is conﬁgured to control the On/Off primary burner operation and ﬂame levels (through six levels) and provide On/Off and Smart control of this appliance.

The receiver connects directly to the gas valve, stepper motor with and umbilical cord wiring harness (see wiring diagram on Page 18).

The Receiver is powered by 4 AA type batteries, located within.

The Receiver accepts commands via radio frequency from the Transmitter and does not require line-of-sight operation.

The Receiver three position slider switch can

be set to one of three positions: ON (Manual Override), REMOTE (Remote Control), or OFF.

Initializing the System for the First Time

Install the 4 AA batteries into the receiver battery bay (behind the wall switch plate).

Note: Install the batteries into the battery bay as indicated on the battery cover. Ensure that batteries are installed with proper polarity (+/-).

Place the three position slider switch in the "Remote" position (see Figure 3, next page). Using the end of a paper clip, or other similar object, insert the end of the paper clip into the hole marked “PRG” on the Receiver front cover. The Receiver will "beep" three (3) times to indicate that it is ready to synchronize with a Transmitter.

Connect GTMS Wire Harness

Pressure Regulator Tower

Yellow Ground Wire (From DFC Wire Harness)

Install the 3 AAA type batteries in the Transmitter battery bay, located on the base of the Transmitter. With the batteries already installed in the Transmitter, push the ON button. The Receiver will "beep" four times to indicate the Transmitter's command is accepted and sets to the particular code of that Transmitter. The system is now initialized.

Low Battery Power Detection

The life span of the Receiver batteries depends on various factors: quality of the batteries used, the number of ignitions of the appliance, the number of changes to the room temperature set point, etc.

When the Receiver batteries are low, no "beep" will be emitted from the Receiver when it receives an ON/OFF command from the Transmitter. This is an alert for a low battery condition for the Receiver. When the batteries are replaced the "beep" will be emitted from the Receiver when the ON/OFF key is pressed (See “Initializing the System for the First Time,” at left).

When the transmitter batteries are low, a battery icon will appear on the LCD display of the transmitter before all battery power is lost. When the batteries are replaced this icon will disappear.

WARNING

Fire Hazard. Can cause severe injury or death. The receiver causes ignition of the appliance. The appliance can turn on suddenly. Keep away from the appliance burner when operating the remote system or activating manual bypass of the remote system.

CAUTION: Property damage hazard. Excessive heat can cause property damage. The appliance can stay lit for many hours. Turn off the appliance if it is not going to be attended for any length of time. Always place the Transmitter where children can not reach it.

Temperature Indicator Display

With the system in the "OFF" position, press the

Room Temperature Key and the Mode Key at

the same time (see Figure 4, next page). Look at the LCD screen on the Transmitter to verify that a C or F is visible to the right of the Room Temperature display (see Figure 5, next page).

Turn On The Appliance

With the receiver switch in the "Remote" position, press the ON/OFF Key on the Transmitter. The Transmitter display will show all active Icons on the screen. At the same time, the Receiver connects to the gas valve coil and the appliance main burner turns on. A single "beep" from the Receiver will conﬁrm reception of the command.

Turn Off The Appliance

Press the ON/OFF Key on the Transmitter. The Transmitter LCD display will only show the room temperature and Icon. At the same time, the Receiver disconnects the gas valve coil and the appliance burner turns off. A single "beep" from the Receiver conﬁrms reception of the command.

Remote Flame Control

The system has six (6) ﬂame levels. See Figure 6 (next page) for an example. With the system on, and the ﬂame level at the maximum in the appliance, pressing the Down Arrow Key once will reduce the ﬂame height by one step until the ﬂame is turned off.

The Up Arrow Key will increase the ﬂame height each time it is pressed. If the Up Arrow Key is pressed while the system is on but the ﬂame is off, the ﬂame will come on in the high position (see Figure 7, next page). A single "beep will conﬁrm reception of the command.

MAINTENANCE

(See Maintenance Schedule, Page 23)

Refer to the maintenance schedule for maintenance tasks, procedures, frequency and by whom they should be performed. Always verify proper operation of the appliance after servicing.

WARNING

Turn off gas and electrical power to the ﬁreplace and allow it to cool before cleaning or servicing the appliance.

CAUTION: Wear gloves and safety glasses for protection while doing required maintenance.

Verify proper operation after servicing.

S'assurer que l'appareil fonctionne adéquatement une fois l'entretien terminé.

Always turn off gas to the pilot before cleaning. Before relighting, refer to the lighting instructions in this manual. Instructions are also found on a pull-out panel located in the control compartment.

Before relighting the ﬁreplace, refer to the lighting instructions in this manual. Instructions are also found on pull-out panels located in the control compartment.

Inspect Venting System

The appliance and venting system should be thoroughly inspected before initial use and at least annually by a qualiﬁed service technician (inspection should include ensuring that exhaust or intake passages are unobstructed and vent components are properly assembled and not damaged). Homeowner must contact

a qualiﬁed service technician at once if any abnormal condition is observed.

If the venting system is disassembled for any reason, a qualiﬁed service technician should follow vent installation instructions for proper reassembly and proper sealing of the venting system components. However, more frequent periodic inspections and cleanings should be performed by the homeowner.

Glass Cleaning

(For detailed glass door assembly removal/ installation instructions, see Page 12.)

Note: Clean glass after ﬁrst two weeks of operation (after burn-in period is over) and then only when necessary and ONLY WHEN THE APPLIANCE IS COOL. Wipe surface with clean, dampened, soft cloth. Follow with dry, soft towel as desired. Take care not to scratch the glass surface.

IMPORTANT: Do not use abrasive cleaners on glass. Never clean the glass when it is hot.

Clean the glass periodically, to remove any buildup caused by the following:

• Filmy coating (during initial use after installation). Initial curing of the high temperature

paint and burning off of lubricants used in the manufacturing process may result in a ﬁlmy coating on the glass.

• Dusty or dirty buildup. It is normal for con- densation and fog to form on the inside of the glass when ﬁrst starting the appliance. This condensation and fog will usually disappear within a few minutes; however, over time the moisture can cause lint, dust, and other airborne particles to cling to the glass surface.

• White coating. A white coating may form on the glass as a result of impurities and minerals in the fuel.

It is recommended that the glass be cleaned two or three times during each heating season, depending on the circumstances. The following cleaning solutions are approved for use to clean the glass:

• Non-ammonia based household cleaner

• 50% white vinegar and 50% water

• Gas replace/stove glass cleaner

Inspect Glass Gasket

Visually inspect the gasket on the backside of the glass enclosure panels. The gasket surface must be clean, free of irregularities and seated ﬁrmly.

Clean Control Compartment

Keep control compartment clean by vacuuming

or brushing at least twice a year. More frequent

cleaning may be required due to excessive lint from carpeting, bedding materials, etc. It is important that control compartments, burners and circulating air passageways of the appliance be kept clean.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Clean Logs and Burner

Carefully remove the logs (use care when handling the ﬁber logs, as they become quite fragile after curing). Vacuum out any foreign matter (lint, carbon, etc.) on the burner. Ensure the burner ports are “open.” Remove any carbon deposits from the under side of the logs using a vacuum cleaner, or a soft bristled brush (i.e. paint brush).

Note: Improper positioning of logs can create carbon build-up and will alter the performance of the appliance.

Replacing Logs

If the logs become damaged by accident or improper handling and need replacement, use only the proper replacement logs from manufacturer (see Pages 18, 25, and 26 for ordering information).

Reinstall Embers, Volcanic Stone, and Logs

Carefully follow placement instructions on Pages 13–15). All logs should ﬁt onto corresponding pins and/or log stoppers. This will ensure a proper ﬂame and safe combustion.

Inspect Wiring

Refer to wiring diagram on Page 18.

CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.

ATTENTION: Au moment de l'entretien des commandes, étiquetez tous les ﬁls avant de les débrancher. Des erreurs de cáblage peuvent entraîner un fonctionnement inadéquat et dangereux.

Inspect and clean all wire connections. Ensure that there is no melting or damage. Inspection should include:

• Terminals at the valve

• OFF/ON Switch

Inspect Burner Flame Appearance

Ensure that the burner flame appearance resembles the ﬂame shown in Figures 20 and

21 and as described in Flame Appearance and Sooting on Page 16. The homeowner must

contact a qualiﬁed service technician at once if any abnormal condition is observed.

Small Area Paint Touch-up

BURNER ADJUSTMENTS

(QUALIFIED TECHNICIANS ONLY)

Flame Appearance and Sooting

Proper ﬂame appearance is a ﬂame that is blue at the base and becomes yellowish-orange in the body of the ﬂame. When the appliance is ﬁrst lit, the entire ﬂame may be blue and will gradually turn yellowish-orange during the ﬁrst 30 minutes of operation. After 30 minutes of operation, if the ﬂame is blue, or if the ﬂame is orange with evidence of sooting (black tip), the air shutter opening may need to be adjusted.

If the air shutter opening is closed too far, sooting may develop. Sooting is indicated by black puffs developing at the tips of very long orange ﬂames. Sooting results in black deposits forming on the logs, appliance inside surfaces and on exterior surfaces adjacent to the vent termination.

Sooting is caused by incomplete combustion in the ﬂames and lack of combustion air entering the air shutter opening. To achieve a warm yellowish-orange ﬂame with an orange body that does not soot, the shutter opening must be adjusted between these two extremes.

Burner Air Shutter Adjustment Guidelines

• If there is smoke or soot present, rst check

the log set positioning to ensure that the ﬂames are not impinging on any of the logs. If the log set is properly positioned and a sooting condition still exists, then the air shutter opening should be increased.

• The more offsets in the vent system, the larger

the air shutter opening will need to be.

• An appliance operated with the air shutter

opened too far, may have ﬂames that appear blue and transparent. These weak, blue and transparent ﬂames are termed anemic.

• Propane models may exhibit ames which

candle or appear stringy. If this is present and persists, adjust the air shutter to a more OPEN position, then operate the appliance for a few more minutes to ensure that the ﬂame normalizes and the ﬂames do not appear sooty.
