GENERAL INFORMATION

The ﬁreplace models covered in this manual are direct-vent, sealed combustion gas ﬁreplaces designed for residential, commercial, and manufactured home applications. 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, co-axial (intake/exhaust) vent system.

These electronic appliances are designed to operate on natural gas and have an electronic intermittent pilot ignition system. External 120 Volt AC electrical power is is required to operate these units.

These appliances comply with National Safety Standards and are tested and listed by Intertek (Report No. 100513650PRT-001) to ANSI Z21.50b-2009 (in Canada, CGA 2.22b-2009), and CAN/

CGA-2.17-M91 (R2009) in both the USA and

Canada, as vented gas ﬁreplaces.

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 Installation Code, CAN/CGA 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 control and receiver allow you to command the functions of your ﬁreplace from the comfort of your chair. They are conﬁgured to control the primary burner operation, its ﬂame levels (through six levels) and provide ON/OFF and smart control of this appliance.

The control board connects directly to the gas valve and stepper motor (see Wire Diagram on Page 18).

The control is powered by four (4) AA batteries in the wall switch and/or 120 VAC line power.

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

The ON/REMOTE/OFF switch can be set to

one of three positions:

• ON (manual override)

• REMOTE (remote control)

• OFF

Initializing the System for the First Time

Install four (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 ON/REMOTE/OFF switch in the REMOTE position (see Figure 3 on Page 10).

Insert the end of the paper clip (or other similar object) into the hole marked "PRG" on the receiver front cover. The control board, located in the ﬁreplace, 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 three (3) AAA batteries in the transmitter battery bay, located on the base of the transmitter. With the batteries installed in the transmitter, push the ON button. The receiver will "beep" four (4) times to indicate the transmitter command has been accepted and is set 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

• Number of ignitions of the appliance

• 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).

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. Control will automatically shut off after 24 hrs of continued operation

the Room Temperature Key and the Mode

Key at the same time (see Figure 4 on Page 10). 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 on Page 10).

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 on Page 10 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 on Page 10). 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 the gas before cleaning. Before re-lighting, refer to the lighting instructions in this manual. Instructions are also found on a pull-out panel located in the control compartment.

Always keep the appliance area clear and free from combustible materials, gasoline and other ﬂammable liquids.

Before re-lighting 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

See Front Glass Enclosure Panel, Removal and Installation on Page 13.

NOTE: Clean glass after ﬁrst two weeks of operation (after Burn-In period is over) and then only when necessary and when the ﬁreplace is cool. Wipe surface with clean, dampened, soft cloth. Follow with a dry, soft towel as desired. Take care not to scratch the glass surface.

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

The viewing glass should be cleaned periodically to remove any build-up caused from the following:

• During start-up, it is normal for

condensation to form on the inside of the glass (this condensation and fog will usually disappear in a few minutes). The moisture can cause lint, dust and other airborne particles to cling to the glass surface.

• Initial curing of the high temperature paint

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

• 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 present. The following cleaning solutions are approved for use to clean glass:

• Non-ammonia based household cleaner

• 50/50 mix of white vinegar & 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.

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: Improperly positioned 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 Page 18 for ordering information).

Re-install Embers, Volcanic stone and Logs

Carefully follow placement instructions on Pages 14 and 15). All logs should ﬁt onto corresponding pins and/or log stoppers. This will ensure a proper ﬂame and safe combustion.

NOTE: If installing the contemporary burner/ ﬂoor kit, skip this step and instead refer to the instructions provided with the kit.

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 there is no melting melting or other damage. Inspection should include:

• Terminals at the valve

• Wall ON/REMOTE/OFF switch

Low Battery Power Detection

The life span of the remote control system batteries depends on many factors:

• the quality of the batteries used

• the number of appliance ignitions

• etc.

When the batteries are low, the receiver will emit two (2) beeps (low battery alert) when it receives a command from the transmitter.

After the batteries are replaced, the receiver will emit one (1) beep when it receives a command from the transmitter. See "Initialization of the System" in the Installation Instructions (P/N 506023-16).

Inspect Burner Flame and Pilot Flame Appearance

Periodically do a visual check of the burner ﬂame and the pilot ﬂame. Ensure that the burner ﬂame appearance resembles the ﬂame shown in Figures 18 and 19 and as described in Flame Appearance and Sooting on Page 16. Refer to Figure 20 on Page 17 for more information about the pilot ﬂame appearance. Contact a qualiﬁed service technician at once if any abnormal condition is observed.

Small Area Paint Touch-up

Only use a factory supplied paint kit for touch-ups. Paint is available at your local Lennox Hearth Products dealer. Never attempt to paint a hot ﬁreplace.

If the surface later becomes stained or marred, it may be lightly sanded and touched up with spray paint.

BURNER ADJUSTMENTS

(QUALIFIED TECHNICIANS ONLY)

Flame Appearance and Sooting

Proper ﬂame appearance is a ﬂame which is blue at the base and becomes yellow-orange in the body of the ﬂame. When the appliance is ﬁrst lit, the entire ﬂame may be blue and will gradually turn yellow-orange during the ﬁrst 15 minutes of operation. After 15 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 yellow-orange ﬂame with an orange body that does not soot, the shutter opening must be adjusted between these two extremes.

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.

Burner Air Shutter Adjustment Procedure

WARNING

• Air shutter adjustment should only be performed by a qualiﬁed professional service technician.

• Ensure that the front glass

door assembly is in place and sealed After adjustment.

CAUTION

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Soot will be produced if the air shutter is closed too much. Any damage due to carboning resulting from improperly setting the air shutter is not covered under the warranty.

The following paragraphs address burner adjustment concerns and procedures.

When lit for the ﬁrst time, this appliance will emit a slight odor for an hour or two. This is due to the “burn-in” of internal paints and lubricants used in the manufacturing process.

Adjustment

To adjust the ﬂame, move the adjustment air shutter (located on the lower venturi) back or forward to increase or reduce the air shutter opening, respectively. Position the air shutter to the factory setting as shown in Table 8. Allow the burner to operate for at least 15 minutes. Observe the ﬂame continuously. If it appears weak or sooty as previously described, adjust the air shutter until the ﬂame appearance is as desired.

When satisﬁed that the appliance operates properly, ﬁnish the installation. Leave the wall

ON/REMOTE/OFF switch in REMOTE position

and turn the remote switch OFF.
