Installation & Operating Instructions

This gas appliance should be installed by a qualified installer in accordance with local building codes and with current CSAB149.1 Installation codes for Gas Burning Appliances and Equipment. FOR U.S. Installations follow local codes and/or the current National Fuel Gas Code ANSI Z223.1/NFPA 54.

In the Commonwealth of Massachusetts, all gas fittings and installation of this heater shall only be done by a licensed gas fitter or licensed plumber.

FOR SAFE INSTALLATION AND OPERATION OF YOUR GAS FIREPLACE PLEASE NOTE THE FOLLOWING:

1.This appliance gives off high temperatures and should be located out of high traffic areas and away from furniture and draperies.

2.Children and adults should be alerted to the hazards of the high surface temperatures of this appliance and should stay away to avoid burns or ignition of clothing.

3.Children should be carefully supervised when they are in the same room as your appliance.

4.Under no circumstances should this appliance be modified. Parts removed for servicing should be replaced prior to operating this appliance again.

5.Installation and any repairs to this appliance should be carried out by a qualified service person. A professional service person should be contacted to inspect this appliance annually. Make it a practice to have all of your gas appliances checked annually. More frequent cleaning may be required due to excess lint and dust from carpeting, bedding material, etc.

6.Control compartments, burners and air passages in this appliance should be kept clean and free of dust and lint. Make sure that the gas valve and pilot light are turned off before you attempt to clean this unit.

7.The venting system (chimney) of this appliance should be checked at least once a year and if needed your venting system should be cleaned.

8.Keep the area around your appliance clear of combustible materials, gasoline and other flammable vapor and liquids. This appliance should not be used as a drying rack for clothing, nor should Christmas stockings or decorations be hung in the area of it.

9.Under no circumstances should any solid fuels (wood, coal, paper or cardboard etc.) be used in this appliance.

10.Whether the zero clearance kit is installed directly on carpeting, vinyl tile or any combustible material other than wood, this heater must be installed on a metal or wood panel extending the full width and depth of the heater. The insert can not be installed directly onto or into combustibles.

Proposition 65 Warning: Fuels used in gas, woodburning or oil fired appliances, and the products of combustion of such fuels, contain chemicals known to the State of California to cause cancer, birth defects and other reproductive harm.

California Health & Safety Code Sec. 25249.6

WARNING: Check with your electronics manufacturer before installing a television or other electronic device above this fireplace.

IMPORTANT:

PLEASE READ THE FOLLOWING CAREFULLY

It is normal for fireplaces fabricated of steel to give off some expansion and/or contraction noises during the start up or cool down cycle. Similar noises are found with your furnace heat exchanger or car engine.

It is not unusual for your gas fireplace to give off some odor the first time it is burned. This is due to the curing of the paint and any undetected oil from the manufacturing process.

Please ensure that your room is well ventilated - open all windows.

It is recommended that you burn your fireplace for at least ten (10) hours the first time you use it. If optional fan kit has been installed, place fan in the "OFF" position during this time.

Mantels

When the unit is installed into a woodburning fireplace, the minimum distance the mantel can be placed above the fireplace is governed by local building codes applicable to woodburning fireplaces. Consult local authorities having jurisdiction for these clearances.

For applications requiring the use of a Zero Clearance Kit, the minimum height a mantel can be installed above the fireplace is 24" (610 mm) from the top of the upper louvres. The maximum mantel depth is 8" (203 mm). (Fig. 2)

The underside of the mantel will become warm. Use only finishes which are heat resistant and do not discolor.

24" Min. (610mm)

FP1325

Fig. 2 Minimum mantel height above fireplace.

Framing & Finishing

For Zero Clearance Kit applications, it is important to determine the finished facing material before beginning to frame. This will allow for the thickness of the finishing material between the frame and the fireplace trim.

Similarly, consideration must be given to the 1" inch depth of the air inlet channel sitting on the fireplace base. Finishing material for the hearth should be flush with the top of the air inlet channel.

If the fireplace is installed at floor level a noncombustible hearth must extend a minimum 12" (305 mm) in front of the fireplace.

If the fireplace is recessed into the wall and at least 12" (305 mm) above floor level, no hearth is required.

The use of wallpaper adjacent to this fireplace is not recommended as high temperatures given off by this fireplace may adversely effect the binders in the adhesive used to apply the wallpaper.

Zero Clearance Applications

An alternate air supply is recommended with this component.

For installation other than in existing woodburning fireplaces such as new construction or renovation projects, a Zero Clearance Kit must be used. The kit enables these inserts to be installed in combustible environments. Whenever using a Zero Clearance Kit, consideration must be given to the dimensions of the Zero Clearance Kit and the requirements of the Air Kit.

NOTE: If a Zero Clearance Kit is required for models LHECDV20/LHERDV20/LHECDV30/LHERDV30 Direct Vent Inserts, only the CFM Corporation zero clearance kit HEZC combined with the HEDVCAK is approved to be used. Refer to Page 9, figure 10 for HEDVCAK chimney adapter kit installation. When using the HEZC with insert models LHECDV20 or LHERDV20, the Trim Closure Kit, LHE20TCK, must also be installed.

Vented Gas Fireplace Heaters

Preparation

Before beginning, remove glass door and logs from unit. Also check to make sure there is no hidden damage to the unit. Take a minute and plan out the gas,venting and electrical route. It is best to start with the gas line first followed by the chimney liner. (Refer to Page 9)

Gas Line Installation

When purging the gas line, the front glass must be removed.

If gas piping from the source to the heater location has not been accomplished, install the required pipe. Consult local plumbing code to assure proper pipe size.

The gas pipeline can be brought in through the rear or the base of the heater.

NOTE: The gas line connection can be made of either properly tinned 3/8" copper tubing, 1/2" rigid pipe or an approved flex connector then reduced to 3/8" to the

heater. Some municipalities have additional local codes, it is always best to consult your local authority and the CSAB149.1 installation code.

U.S. Installations consult the current National Fuel Gas Code, ANSI Z223.1/NFPA 54.

Always check for gas leaks with a mild soap and water solution. Do not use an

open flame for leak testing.

The gas control is equipped with a captured screw type pressure test point, therefore it is not necessary to provide a 1/8" test point up stream of the control.

When using copper or flex connector, use only approved fittings. Always provide a union when using black iron pipe so the gas line can be easily disconnected for burner or fan servicing. See gas specifications for pressure details and ratings. NOTE: If flex connector is used, it must be kept inside of the heater.

Gas Supply Pressures

This heater must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure equal to or less than 1/2 psig (3.45kPa).

The heater and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.45kPa).

Fan Kit

115 volt, 60 Hz. 56w (Model FK24)

NOTE: The LHERDV20 and LHERDV30 are not designed for a fan kit.

The fan kit includes the following: fan, temperature sensor, speed control and a 6 ft. cord. The following explains how to start and set the fan for automatic operation.

1.Plug in the electrical cord.

2.Start gas fire - see lighting procedures.

3.Turn on fan speed control.

4.Wait until the unit has warmed up sufficiently to activate the temperature sensor, approx. 5-10 minutes.

5.Once fan starts, adjust speed control to desired fan speed. The fan will now automatically come on every time the fireplace is in operation. Should the fan not be needed simply turn off the speed control.

Venting Installation

1.The fireplace may be installed in and vented through any solid fuel fireplace that has a minimum fireplace opening 25¹⁄ "W x 17¹⁄ " H x 13¹⁄ "D (641 x 438 x 343 mm) for LHECDV20 and LHERDV20 or 28³⁄ "W x 21"H x 15¹⁄ "D (730 x 533 x 394 mm) for LHECDV30 and LHERDV30 and has been installed in accordance with the National, Provincial/State and local building codes and is constructed of noncombustible materials.

2.Only HEDVRT RD vent termination kit, HEDVT (8 x 12) or HEDVT (12 x 12) termination kit and flex vent kit HEDVK25 or HEDVK35 are to be use din this installation. Under no circumstances should B vent or C vent be used on this application.

3.Any flue damper must be removed or blocked open.

5.The chimney must be clean and in good working order and constructed of noncombustible materials.

6.Make sure that all chimney cleanouts fit properly so air cannot leak into the chimney.

7.Install the appliance without trim frame and make all gas fittings and electrical connections.

8.Install the decorative trim frame. Please refer to the Frame Assembly instructions.

Installer must attach red warning plate with screws supplied with the gas fireplace insert to the inside of the firebox of the fireplace into which the gas fireplace insert is installed.

Cutting any sheet metal parts of the fireplace, in which the gas fireplace insert is to be installed, is prohibited.

If the factory-built fireplace has no gas access hole(s) provided, an access hole of 1¹⁄ (38 mm) or less may be drilled through the lower sides or bottom of the firebox in a proper workmanship-like manner. This access hole must be plugged with a noncombustible insulation after the gas supply line has been installed.

WARNING

Some factory-built fireplaces have air passages on face of fireplace for zero clearance capabilities.

Under no circumstances should these passages be blocked.

Liner Installation

The collar extending down from the termination base is the air intake connector. Be sure the flex vent, which is connected to this collar, is also connected to the labelled air intake flue collar on the fireplace. Make sure the flex vent is attached on the correct collar and cap for exhaust as well.

Slide the insulation provided in the termination kit over the two (2) 3" flex liners, (to be attached to the 3" flue collar and cap of the termination). Feed one 3" flex vent from the bottom of the termination up through the 4" sleeve. Apply hi-temp sealant on the rain cap collar and slide the flex vent over the end of the rain cap collar fastening with the clamp provided. Slide the flex liner back down the 4" sleeve until 4" cap slides over the sleeve. Attach cap to the sleeve with four (4) screws supplied. Apply hi-temp sealant over the air intake collar and attach intake flex vent in the same method. Feed the two flex liners down the chimney through the damper opening. Tighten termination to the chimney using the screws provided. (Fig. 10) NOTE: For Round Vent Terminations - tighten termination to the chimney by pushing the four (4) straps of the vent termination against the chimney and secure with four (4) screws provided. (Fig. 12)

In case the fireplace opening is only minimum height 21" (533 mm) and access from the front is not possible, follow the instructions below.

1.Remove flue collar plate assembly. Unbolt the top fastener plate and move it to the back first before sliding the flue collar plate out from the top of the unit. (Fig. 13)

2.Apply a bead of hi-temp sealant on the end of the collar before attaching the liner to the flue collar. Fasten it with two clamps then adjust fastener plate all the way to the back before sliding flue gas plate back onto the unit. (Figs. 14 and 15)

3.After the flue collar plate is set on the cabinet top, make sure the front edge of the flue collar plate is completely in contact with the back edge of the cabinet top. (Fig. 16)

4.Put the machine screw back into the fastener plate. Bolt the plate until it is locked. (Fig. 17)

Under no circumstances should insulation be put between the damper and the top of the unit. This may cause condensation and overheating of the unit.
