2 Getting Started

A. Design and Installation Considerations

WARNING! Risk of Fire or Explosion! Read all instruc­ tions before starting the installation.

Gas inserts are designed for installations into solid fuel masonry or UL127 listed factory built fireplaces. No additional outside air source is required.

Installation MUST comply with local, regional, state and national codes and regulations. Consult insurance carrier, local

building inspector, fire officials or authorities having jurisdiction over restrictions, installation inspection and permits. Prior to installing the gas insert:

• Ensure chimney is constructed of non-combustible materials.

• Ensure chimney is clean and in good working order.

• Ensure that all chimney cleanouts fit properly to prevent air leakage into chimney.

• Ensure combustible mantel and surround clearances comply with insert requirements.

• Ensure all joints are properly engaged and the chimney is properly secured.

• Determine minimum fireplace size. See Section 4.A.

• Determine gas supply piping requirements.

• Determine electrical wiring requirements.

• Determine finishing details.

• Determine whether optional accessories—devices such as a wall switch or remote control—are desired.

Installation and service of this appliance should be performed by qualifiedpersonnel.Hearth&HomeTechnologiesrecommends HHT Factory Trained or NFI certified professionals.

Improper installation, adjustment, alteration, service or maintenance can cause injury or property damage. For assistance or additional information, consult a qualified service technician, service agency or your dealer.

B. Tools and Supplies Needed

Before beginning the installation be sure that the following tools and building supplies are available.

Tape measure	Pliers
Hammer	Phillips screwdriver
Voltmeter	Electric drill and bits (1/4 in.)
Gloves	Safety glasses
Level	Reciprocating saw
Manometer	Flat blade screwdriver

Noncorrosive leak check solution

1/2 - 3/4 in. length, #6 or #8 Self-drilling screws

Caulking material (300 ºF minimum continuous exposure rating)

C. Inspect Appliance and Components

•Carefully remove the appliance and components from the packaging.

•The vent system components and decorative barrier fronts may be shipped in separate packages.

•If packaged separately, the log set and appliance grate must be installed.

•Report to your dealer any parts damaged in shipment, particularly the condition of the glass.

•This product is factory-equipped with an IntelliFire Touch remote control, which was paired to the appliance at the factory. This specific remote control needs to remain with the contents of the manual bag. Do not install batteries in the remote control until performing the final appliance setup and checklist.

•Read all of the instructions before starting the installation. Follow these instructions carefully during the installation to ensure maximum safety and benefit.

Hearth & Home Technologies disclaims any responsibility for, and the warranty will be voided by, the following actions:

•Installation and use of any damaged appliance or vent system component.

•Modification of the appliance or vent system.

•Installation other than as instructed by Hearth & Home Technologies.

•Improper positioning of the gas logs or the glass door.

•Installation and/or use of any component part not approved by Hearth & Home Technologies.

Any such action could cause a fire hazard.

4 Fireplace Size Requirements

A. Minimum Fireplace Opening

Minimum fireplace opening requirements are shown in

Figure 4.2.

WARNING! Risk of Fire or Burns! Provide adequate clearance around air openings and for service access.

Due to high temperatures, the appliance should be located out of traffic and away from furniture and draperies.

Minimum fireplace opening requirements for factory-built fireplaces.

•The firebrick (refractory), glass doors, screen rails, screen mesh and log grates can be removed from a factory built firebox in order to gain minimum gas insert opening requirements.

•Any smoke shelves, shields and baffles may be removed from the factory built firebox if attached with mechanical fasteners.

•The appliance may not be placed directly on the base of the outer wrap, a 1/4 in. airspace MUST be provided between the insert and the floor of the outer wrap. Use the levelling legs to raise the insert a minimum of 1/4 in.. The original fireplace may never be returned to solid fuel in this condition. The sidewalls and top structure of the firebox may not be altered with the exception of removable baffles and dampers.

•The metal floor of the factory-built fireplace may be removed to facilitate the installation of the insert.

•Cutting of any sheet metal parts of the fireplace in which the gas fireplace insert is to be installed is prohibited, except the floor as tested for and as noted above and in

Figure 4.1-B.

•A minimum 1/2 in. gap from the bottom of the appliance to the metal floor of the factory-built firebox is

RECOMMENDED to avoid fan motor resonance noise. See side view in Figure 4.1-A.

•If the recommended 1/2 in. leveling leg height can not be achieved, a section of the factory-built metal floor may be removed. See Figure 4.1-B and see Section 10.A for clearance under appliance.

Note: The metal warning plate, noting that the factory-built fireplace has been converted for use with a gas fireplace insert, must be affixed to the appliance. It is included in the manual bag assembly.

B. Wall Extension

Surrounds MUST overlap wall extension.

A non-combustible wall extension can be used to cover an existing masonry surface. Wall extensions are typically used to improve cosmetics.

WARNING! Risk of Fire! Comply with all minimum clearances to combustibles as specified. Framing or finishing material closer than the minimums listed must be constructed entirely of noncombustible materials (i.e., steel studs, concrete board, etc).

Combustible facings must not extend behind the insert surround. See Section 1.E and 1.F.

Non-Combustible Materials Specification

Material which will not ignite and burn. Such materials are those consisting entirely of steel, iron, brick, tile, concrete, slate, glass or plasters, or any combination thereof.

Materials that are reported as passing ASTM E 136,

Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750 ºC.

•Observe all clearances when applying combustible materials.

•Maximum depth of wall extension is 12 inches. This may be limited by the flex pipe’s ability to connect to the starting collar.

•Covering combustible materials with non-combustible materials does not qualify material as non-combustible.

WARNING! Risk of Fire! DO NOT apply combustible materials beyond the minimum clearances. Comply with all minimum clearances to combustibles as specified in this manual. Overlapping materials could ignite and will interfere with proper operation of decorative barrier fronts.

Figure 4.6 Transition Sealing Detail for Wall Extensions (Side View)

Wall Extension

Wall extension must be sealed to existing masonry wall. See Figure 4.6. Framing studs may not sit flush against existing masonry wall. In order to keep heat from escaping behind the wall this transition must be sealed.

• Seal with a high temperature silicone 300 °F. and / or

•Packing insulation into voids between the masonry wall and steel studs is acceptable.

Note: Combustible materials may be used to seal wall extension to existing masonry wall as long as it is outside the non-combustible zone.

Painting

If desired finishing includes a painted wall, a high-quality

100% acrylic latex paint with a high-quality latex primer base coat are recommended around the appliance to limit discoloration. Oil-based or standard acrylic paints may be more prone to discoloration due to heat exposure.

Drywall Joint-Crack Prevention and Repair

Drywall joints around the fireplace will be affected by exposure to elevated temperatures, along with other environmental, structural factors due to new construction, and methods used to install and finish the drywall. If a crack does emerge adjacent to the fireplace, it can be permanently repaired by filling it with a paintable latex caulk, followed by repainting.

Some movement of the screws used to secure the noncombustible board to the appliance/surround framing is expected. If a blemish begins to show over a screw head, sand the surface to remove the blemish and repaint.

NOTE: Concealed sections of 3 in. flex pipe must be contained inside existing masonary fireplace flue vent or installed into an existing wood burning vent system.
