OPERATING THE MONTECITO ESTATE

Fuel - USE SOLID NATURAL WOOD FUEL

ONLY. The Montecito Estate is designed to work best when fueled with dry seasoned natural wood only. Hardwoods are preferred to softwoods since the energy content of wood is relative to its density. Hardwoods will result in a longer burning ﬁre and less frequent refueling. A moisture content of 15% to 20% (seasoned) is recommended. Wood that has been cut and split and let to dry under a cover for a period of one year will usually meet that criteria. Excessively wet wood will be difﬁcult to burn and will result in lower efﬁciency, increased creosoting and deposits on the glass and in the chimney. Excessively dry wood will burn well but will also have higher emissions and shorter burning time.

Do not burn scrap or garbage, treated wood or wood such as driftwood from the ocean which has been exposed to salt or other chemicals. Salt or chemicals can corrode the ﬁrebox and chimney. Do not burn large amounts of paper, cardboard, Christmas tree branches or building construction materials. Intense ﬁring with these materials may overheat the ﬁreplace, causing damage to the unit, a ﬁre or even possibly igniting a chimney ﬁre if the chimney is creosoted.

First Fires

Before using the ﬁreplace make sure to remove the plastic wrapping and EPA label on the door. Remove any glue residue left by the label using mild soap.

Make sure the doors are properly adjusted, thus avoiding color change to ﬁnish due to overheating.

The ﬁrst ﬁve or six ﬁres should be small ﬁres of short duration (about 30 to 60 minutes). This will help cure the refractory bricks. The ﬁrst ﬁres may produce slight smoking due to curing of the paint and steel and the burning of any dust accumulated on the ﬁreplace which will burn off at this time. It may set off a smoke alarm located in the same room. For this reason the room should be well ventilated for the ﬁrst few ﬁres.

HEAT OUTPUT

The Montecito Estate is the largest member of the “Dave Lennox Signature Collection” of high efﬁciency ﬁreplaces. The heat generated from its ﬁre is more efﬁciently captured and distributed. In spite of the large amount of heat that the

MontecitoEstatecandeliver,itshouldnotreplace the main source of heat in your home. This ﬁreplace will bring extra warmth and ambiance to your home by distributing its heat as describe

further in the manual.

COMBUSTION CONTROLS

Primary Air & Air Boost Controls

There is no ﬂue damper in the Montecito Estate™. As is common with air tight appliance, the combustion air control sets the ﬂow of air entering the ﬁrebox. This allows for a more precise control of the ﬁre. The combustion air control is located below the door on the left side. The main source of air (primary air) entering the ﬁrebox can be diminished by moving the air combustion control from left to right. The primary air is fully opened when the air control is completely moved to the left. This air combustion control should be in the closed position when the ﬁreplace is not in operation. This will minimize air leakage up the chimney.

The combustion air control should be opened before opening the doors to minimize the possibility of back draft coming into the room (Figure 1-A) More details are available in Refueling For Best Performance on Page 5.

Time Delayed Air Boost System

The time delayed air-boost system register is located underneath the door handles. Placed in the fully opened position, a timer with a maximum duration of 2 hours is engaged. The register gradually reduces the amount of air injected, allowing for a better start of the ﬁre, whatever the conditions (See sections Building a Fire and Refueling For Best Performance for proper sequence of operation). This allows you to start the ﬁre, set the primary air control to the desired burn level and the ﬁreplace will automatically adjust itself to that level once the ﬁre is fully established (Figure 1-B).

Accelerated Combustion

The maximum heat output for the Montecito Estate is achieved by burning with the door closed and the combustion air opened and pulled out. Through this method, the Montecito Estate can produce up to 80,000 BTU of heat per hour.

However, it will be necessary to reload with wood every one or two hours. This is the least efﬁcient method of burning the Montecito Estate .

Use caution when ﬁring with the combustion air control wide open. Only burn cord wood in this manner. Small dry pieces of softwood and construction scraps will burn very intensely using this method and may damage the ﬁrebox.

Figure 2 - Accelerated Combustion

Medium Combustion

This is the recommended mode of operating the Montecito Estate and should be the one normally used since it will deposit the least amount of creosote on the glass and in the chimney. The combustion air control must be 3/4 closed. The precise setting will depend on many factors, including chimney length and the moisture content of the wood.

For instance, a long chimney will necessitate closing the damper more. To obtain the proper combustion, close the damper completely, then open it about 1/4” to 1/2”. Three medium size pieces of cord wood-burning on a bed of hot coals will generate an approximate heat output will of 35,000 BTU per hour and the loading time will be about every 3-4 hours. Softwoods may be burned using this method but the combustion time will be substantially reduced.

Figure 3 - Medium Combustion

Slow Combustion

When the air combustion control is completely closed, the ﬁreplace is in a slow combustion phase. If the hearth is hot enough, slow combustion will not extinguish the ﬁre, but there will be a noticeable change in the ﬂame pattern. The ﬂames will be slow and may appear dirty if the wood is too wet (moisture content of 20% and more).

Do not allow the wood to burn without ﬂame, since this will produce excessive creosote in the unit. Creosote may accumulate on the glass door. This method of burning should be used only after operating the Montecito Estate™ with the air control opened to produce a hot ﬁre for about an hour or at medium pace for at least three (3) hours. Slow combustion can be used at night in order to reduce the heat output and to prolong the burn. The loading time will be between 6-8 hours and at this combustion rate, the level of BTU’s is at its lowest.

Figure 4 - Slow Combustion

Building a Fire

A)To start a ﬁre, place several crumpled up balls of newspaper in the ﬁrebox. Place small dry pieces of kindling on top of the paper, criss-crossing the kindling so that there are air spaces in between. The kindling should be placed at the center of the ﬁrebox so as to allow for sufﬁcient air circulation.

B)Adjust the primary air control and start the time delayed air-boost system by pushing the register towards the right. Light the newspaper. Leave the doors partially opened to facilitate the start-up.

C)Once kindling ﬁre is well established, cord wood can be added. You may set the primary air control to the desire level (see Primary Air Combustion Control and Air Boost Controls section for proper operation of the air controls).

D)Set the primary control to the desired burn level. The ﬁreplace will automatically go to that level after the ﬁre is fully established and the air boost is closed.

The unit will burn best with 2-3 pieces of cord wood spaced 1 to 2 inches apart and allowing air to get under the fuel. Criss-crossing or arranging the fuel so that air can get underneath will help the ﬁre to get started easily. The unit should be operated with the air control fully open long enough to get the cord wood well ignited.

REFUELING FOR BEST PERFORMANCE

To reload the Montecito Estate at the end of a combustion cycle, when no ﬂame is visible and there are only ashes left:

A)Completely open the air control level and the T.D.A.B. (Time Delay Air Boost) level. See Figure 1.

B)Open the doors about 1” and wait 5 seconds until the air ﬂow has stabilized. Then open the doors completely, put the logs in and close the doors.

C)Set the air control to the desired burn level. The T.D.A.B will close by itself progressively.

To reload the Montecito Estatewhen the ﬁreplace is still hot with a few visible ﬂames:

A)Open the air control completely. The T.D.A.B can be set to a lower setting in order to facilitate lighting.

B)Open the doors about 1” and wait 5 seconds until the air ﬂow has stabilized. Then open the doors completely, put the logs in and close the doors.

C)Set the air control to the desired burn level.

Notes:

•For spectacular ﬁre and optimization of the ﬁreplace efﬁciency, we recommend that the wood load be placed as far back as possible.

•It may be necessary to turn off any blower(s) in operation during the refueling process in order to minimise smoking in the room. It is recommended to wait 15 to 30 minutes before turning the blower(s) back on to ensure successful rekindling.

SMOKING –

CAUSES AND TROUBLESHOOTING

To reduce the likelihood of smoke coming into the room when opening the door, set the combustion air controls to the left (“Accelerated Combustion”) before opening the door. Your ﬁreplace has been designed and tested to provide smoke free operation.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

As the ﬁre burns, air goes up the chimney. This air must be replaced through the outside air duct. When operating the Montecito Estate, open a nearby window temporarily to check if there is adequate air supply replacement. Occasionally, there may be a small amount of smoking upon lighting the ﬁre, until the chimney heats up but this should not last. If the ﬁreplace continues to smoke it is probably for one of the following reasons:

A.The doors are partially opened

When you open the doors, open them completely.

B.Negative pressure in the house

C.Fans operating (e.g.: range hood)

These fans draw air out of the house and may actually cause a negative pressure in the house. Turn off all fans and open a nearby window to determine if this is the cause of the problem.

D.Wet wood

Wet or tarred wood will smoulder and smoke instead of burn properly.

E.Dirty or blocked chimney

Check to make sure the chimney is clear and clean.

F.Chimney not long enough

The minimum chimney height is 12 feet not including the ﬁreplace height. The chimney must extend at least three (3) feet (915 mm) above its point of contact with the roof and at least two (2) feet (610 mm) higher than any roof or wall within ten (10) feet (3 m) of it. When installed with offsets, the minimum chimney height is 15 feet. Additional height will increase draft and will decrease the tendency to smoke.

G.Poor chimney draft

With no ﬁre, there should be sufﬁcient draft to exhaust cigarette smoke introduced under the bafﬂe. Chimneys installed against an outside wall without protection may generate back draft problems which will cause start-up problems. To prevent this, open a nearby window; roll up a piece of paper, light it and hold it in the upper part of the ﬁrebox to warm up the chimney. Wait until the draft is sufﬁcient, then start the ﬁre.

IMPORTANT CAUTIONS

A.Do not block the hot air vents to the ﬁreplace as this will cause the ﬁreplace to overheat.

B.Never use gasoline, kerosene, charcoal lighter ﬂuid or similar liquids to start or rekindle a ﬁre in this ﬁreplace. Keep all such liquids well away from the ﬁreplace at all times.

C.Do not burn coal. The sulphur in coal will corrode the ﬁrebox.

D.Do not burn driftwood which has been in the ocean or salt water. The salt will corrode the ﬁrebox and chimney.

E.Do not burn wood in the area in front of the grate.

F.Do not abuse the unit by burning paper, or cardboard or construction material such as pressed wood, plywood or lumber. Wood protectors, metallic paper, coal, plastic, waste, sulphur and/or oil will damage the ﬁreplace.

G.Do not allow the wood to smoulder or burn without ﬂame, since this will produce excessive creosote in the unit.

MAINTAINING YOUR MONTECITO

ESTATE

Creosote

When wood is burned slowly without a ﬂame, it produces tar and other organic vapors which combine with expelled moisture to form a black deposit called creosote which accumulates on the ﬂue lining. When ignited, this creosote makes an extremely hot ﬁre. If the creosote accumulation is large, a creosote ﬁre in the chimney can damage the chimney and overheat the surrounding wood framing. Creosote formation in a chimney can be minimized by making sure there is always visible ﬂame burning, avoid smoldering ﬁres and by proper refueling techniques.

Chimney Maintenance

Regular chimney inspection and maintenance combined with proper operation will prevent chimney ﬁres. Keep your chimney clean. Do not allow more than 1/16” creosote build up in your chimney. The amount of creosote will depend on variables such as frequency of use and type of ﬁre. We recommend that you:

A.Initially inspect the chimney system weekly. From this, you will learn how often it will be necessary to clean your chimney.

B.Have your chimney cleaned by a qualiﬁed chimney sweep. If you wish to clean it yourself, we recommend using a stiff plastic or non-metallic brush. If a metal brush is used, its size should be slightly smaller than the ﬂue to avoid damaging the chimney. Do not use a brush that will scratch the stainless steel interior of the chimney.

C.Do not expect chemical cleaners to keep your chimney clean. The rain cap can be removed for inspection and/or cleaning of the chimney.

Dealing With a Chimney Fire

Regular chimney maintenance and inspection can prevent chimney ﬁres. If you have a chimney ﬁre, follow these steps:

1.IMPORTANT: Close the ﬁreplace door and the combustion air controls; this will stiﬂe the ﬁre.

2.Alert your family of the possible danger.

3.If you require assistance, alert your ﬁre department.

4.If possible, use a dry chemical ﬁre extinguisher, baking soda or sand to control the ﬁre. Do not use water as it may cause a dangerous steam explosion.

5.Ensure that sparks and hot embers coming out of the chimney are not igniting the roof.

6.Do not use the ﬁreplace again until your chimney and ﬁreplace have been inspected by a qualiﬁed chimney sweep or a ﬁre department inspector.

DOOR FRAME FINISH CARE

Use a glass cleaner and a soft cloth to polish the casing. Do not use abrasives such as steel wool, steel pads or an abrasive polish for they may scratch the frame’s ﬁnish.

DISPOSING OF ASHES

Remove ashes only when the ﬁre is out and the ashes are cold (24 to 48 hours after the ﬁre is out).

WARNING

When cleaning the ﬁreplace, the ashes should be placed in a metal container with a tight ﬁtting lid. The closed container of ashes should be placed on a non-combustible ﬂoor or on the ground outside the house, pending ﬁnal disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all cinders have thoroughly cooled.

REFRACTORY REPLACEMENT

The intense heat of the ﬁre will normally cause hairline cracks in the refractory brick. These cracks can be minimized by proper curing as described in section First Fires. They will not normally diminish the effectiveness of the refractory brick. If large cracks develop, then the refractory should be replaced. To replace the refractory bricks, follow these steps:

1.Remove the side refractory brackets (6)

2.Remove the front refractory bricks (3)

3.Remove the bottom refractory brick (4)

4.Remove the left side refractory bricks (5)

5.Remove the right side refractory bricks (2)

6.Remove the back refractory brick (1)

7.Remove the deﬂectors (7) above the tubes (Can be removed without removing other bricks for chimney cleaning)

To install the new refractory bricks, follow the above steps in reverse.

DOOR INSTALLATION

The doors must be put in place only when the installation of the Montecito Estate™ is completed. All you have to do is ﬁt the male part of the hinge, already on the door, to the female part, which is on the ﬁreplace. To remove the doors, simply pull them up from the hinges. The door adjustment has been set at the factory. If the ﬁt is still not perfect, you can adjust the door using the hinge screws (See Figure 7-1)

Figure 6 - Door Installation

DOOR ADJUSTMENT

The doors may need to be adjusted to be completely airtight. The gaskets’ air-tightness can be adjusted using the adjustment screw located on the right side of the ﬁreplace facade (An Allen key #1/8 – not supplied - will be necessary for this adjustment) (see Figure 7-2).

Checking Door Seal

A one-inch strip of paper may be used to perform a test of the integrity of the door seal. Close the door on the paper in at least eight points. It is normal to feel only a slight amount of friction. The door gasket does not need to be “tight” in all areas, since a small amount of leakage is not hazardous or detrimental to the performance of your ﬁreplace.

WARNINGS

•Use only a Lennox Hearth Products glass doors, speciﬁcally designed for the Montecito Estate ﬁreplace.

•The ﬁreplace cannot be operated without a door. Consult your dealer to select the correct door model.

•Important! To assure proper alignment of glass doors: Install this ﬁreplace in a square and plumb condition, using shims as necessary at sides and/or bottom.

Figure 7

GLASS CARE

Glass Replacement

The glass used for the Montecito Estate is a high temperature ceramic glass (1,400° F). If the glass breaks or cracks, it must be replaced with an identical ceramic glass. Tempered glass or ordinary glass will not withstand the high temperatures of the Montecito Estate . Replacement glass should be purchased from a Security Chimneys International dealer (see “Replacement Parts” on Page 22).

Do not operate the unit with cracked or broken glass.

Glass Cleaning

The Montecito Estate is designed to keep the glass clean under normal operating conditions. If the Montecito Estate is operated continuously with the combustion air controls closed, the glass will tend to get dirty unless the fuel, ﬁrebox and glass are maintained at hot temperatures (see section Refueling For Best Performance). To clean the glass, there are a number of specially designed cleaners to remove creosote. Your authorized Lennox Dealer can recommend a suitable cleaner. Regular household glass cleaners will not clean creosote. Do not use abrasives such as steel pads, steel wool or oven cleaner as they will scratch the glass.

Gasket Replacement

Remove the doors from the unit (see section Door Installation) and lay them on a clean nonabrasive surface. To replace the gasket, ﬁrst remove all of the old gasket and gasket cement. Make sure that the surface is totally clean before applying new cement (a high temperature silicone caulking rated at 500° F (260° C), is suitable) or adhesion problems may result. Apply gasket cement to the gasket channel and install the new gasket. This replacement part is available from your Lennox Dealer in the following dimensions:

FIREPLACE INSTALLATION

Locating The Montecito Estate™

The best location to install your ﬁreplace is determined by considering the location of windows, doors, and the trafﬁc ﬂow in the room where the ﬁreplace is located, allowing space in front of the unit for the hearth extension and the mantel, and taking into consideration the location of the hot air ducts (optional), outside air kit and chimney. If possible, you should choose a location where the chimney will pass through the house without cutting ﬂoor or roof joists (see ﬁreplace dimensions on

Pages 8 & 9).

Usually, no additional ﬂoor support is needed for the ﬁreplace. The adequacy of the ﬂoor can be checked by ﬁrst estimating the weight of the ﬁreplace system. Weights are given in the appendix. Next, measure the area occupied by the ﬁreplace. Note the ﬂoor construction and consult your local building code to determine if additional support is needed.

The Montecito Estate may be installed directly on the ﬂoor or on a raised base and a minimum of 80” measured from the base of the appliance to the ceiling is required.

Facade Installation

Install the Facade per instructions provided in Facade Kit (ordered separately - see Page 20).

Hearth Extension Requirements

The Montecito Estate may be installed directly on a combustible ﬂoor; however, the combustible ﬂoor in front of the ﬁreplace must be covered with one inch (1 in) of non-combustible support material (cement board, cement block or other) before applying the ﬁnish material (tile, marble, stone, etc). See Figure 8.

Framing, Facing And Mantel

The construction of the framing, facing, and mantel must be in accordance with the standards and the following illustrations (Figures 10 & 11):

A.Frame the ﬁreplace using 2” x 3” or heavier lumber.

B.WARNING: Combustible materials cannot be used in the space directly above the ﬁreplace, except for the studs above the facade that support the facing and mantel. This area must remain empty for a height of 80” (2,032 mm) measured from the base of the appliance.

C.Frame the ﬁreplace with vertical studs at the sides of the ﬁreplace running from ﬂoor to ceiling (see Figure 10). If combustible facing is to be used, position the studs back, from the front edge of the ﬁreplace (a space that is the thickness of the facing material, so that the facing can be installed ﬂush with the ﬁreplace facing). Frame headers between the vertical studs only as follows:

-Place 2” x 3” or 2” x 4” headers, only along the upper part of the front, side and back faces (some codes may require a 2” x 6” on an outside bearing wall). Do not put wood or any combustible material within the area above the ﬁreplace except on the front facing.

-Place headers only as required to support the facing and mantel.

D.WARNING: The ﬁreplace must not be in contact with any insulation or loose ﬁlling material. Cover the insulation with Drywall panels around the ﬁreplace.

COLD CLIMATE INSTALLATIONS

Climates where temperatures will fall below 32° F (0° C).

The heating performance of the appliance will vary depending upon the level of insulation, house design, how the appliance is operated, etc.

If this ﬁreplace is being installed in a cold climate, it is especially important to seal all cracks around the ﬁreplace and wherever cold air could enter the room with noncombustible material. Also, the outside air inlet duct should be wrapped with noncombustible insulation to minimize the formation of condensation. Do not place insulation materials directly against the chimney sections. We recommend that you use the insulated wall radiation shield since it will maintain the home’s thermal barrier. AC chimney is NOT recommended in cold climates.
