C INSTALLATION INSTRUCTIONS.

In planning the installation for the fireplace, it is necessary to determine where the unit is to be installed and whether optional accessories are desired. Gas supply piping should also be planned at this time.

The fireplace can be mounted on any of these surfaces:

1.A flat hard combustible or non-combustiblesurface.

2.A raised platform of combustible or non-combustiblematerial.

3.Four (4) corners of the fireplace so contact is made on all four perimeter edges on the bottom of the unit. (Example: Four (4) concrete masonry blocks.)

If the fireplace is installed directly on carpeting, tile or other combustible material other than wood flooring, it should be installed on a metal or wood panel extending the full width and depth of the unit.

At this point, you should have decided what components to include in your installation, and where the fireplace is to be located. If this has not been done, stop and consult your dealer for assistance with this planning.

C-1.FIREPLACE FRAMING.

Fireplace framing can be built before or after the fireplace is set in place. Framing should be positioned to accommodate wall covering and fireplace facing material. The fireplace framing should be constructed of 2 x 4 lumber or heavier. The framing headers may rest on the top of the fireplace standoffs. Refer to Fig. 2 and Fig. 3 for fireplace framing dimensions.

C-2.LOCATING FIREPLACE.

Place fireplace in framing opening.

Using the four (4) nailing tabs provided on the fireplace, attach two (2) tabs on each side. Attach tabs through prepunched holes. Additional hole locations will be used for different finishing material with thicknesses of 1/2”, 5/8” and 3/4”. Attach these materials with screws provided, two (2) per nailing tab.

Nailing tabs should fit directly against framing material. Use at least one (1) nail per tab to secure in place.

C-3.CONNECTING THE GAS LINE.

The fireplace is designed to accept a 3/8-inchgas line for an approved gas fireplace. Have the line installed by a qualified service person in accordance with all building codes. Consult local building codes to properly size the gas supply line leading to the3/8-inchhook-upat the unit.

Gas access holes are provided on both sides of the fireplace. Flex line should be used, if approved by local codes, when the line is being installed in the left side of the fireplace. Hard plumbing could get in the way of the air dilution system.

Check gas type. Use only the gas type indicated on the gas log set rating plate. If the gas listed on the plate is not your type of gas supply, DO NOT INSTALL. Contact your dealer for proper model.

Always use an external regulator for all LP fireplaces to reduce the supply tank pressure to a maximum of 14” w.c. This is in addition to the regulator fitted to the heater.

WARNING: CONNECTION DIRECTLY TO AN UNREGULATED L.P. TANK CAN CAUSE EXPLOSION.

The gas line comes into the fireplace under the hearth pan, although it is not necessary to remove the hearth pan. This pan is removable to make installation of the gas line and all the accessories easier.

To remove the hearth pan, back out all screws that hold the pan in place, ten (10) screws for 42” and eight (8) screws for 36” in the bottom pan, one (1) on each side of the surround. (See Fig. 5). After installation of all accessories, replace hearth pan in reverse order of its removal.

The gas line should be run directly to the bulkhead connector located in the middle/back of the hearth pan. This plumbing should be connected, using all approved unions and shut-offsinstalled in the system. After making the proper gas line connection to the bulkhead, reinstall the hearth pan using the screws you removed.

C-4.GAS LOG SET SIZING FORVENT-FREEFIREPLACE.

Install only a ANSI Z21.11.2 appliance into this fireplace. The size of the Z21.11.2 appliance should follow Fig. 6 and the clearances shown above.

C-5.ELECTRICAL CONNECTION.

The VFFB36/42D with optional fan requires 120 VAC electrical hookup to the electrical box (installed).

CAUTION: ALL WIRING SHOULD BE DONE BY A QUALIFIED ELECTRICIAN AND SHALL BE IN COMPLIANCE WITH ALL LOCAL, CITY AND STATE BUILDING CODES. BEFORE MAKING THE ELECTRICAL CONNECTION, MAKE SURE THAT MAIN POWER SUPPLY IS DISCONNECTED. 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).

A factory installed electrical box is located on the lower right hand side of the fireplace. Wiring must be fed to the electrical box and attached to the receptacle that you must provide. Remove the knockout in the installed junction box to accept wiring into the junction box. Install a UL listed cable clamp (not supplied) in the knockout hole. Leave approximately 6” of wire in the junction box for connection.

Attach black wire to one side of the receptacle and white wire to opposite side of receptacle.

The ground wire should be attached to the green (neutral) screw.

Install the receptacle into the metal box. Attach cover plate.

C-6.OPTIONAL FRESH AIR INTAKE KITS

MODEL: VFFB-AK-36

VFFB-AK-42

Installation of our 6" fresh air intake kit is simple and easy to complete. This system MUST BE installed before the fireplace is enclosed with finishing material.

Install model VFFB-AK-36onVFFB-36D.Install modelVFFB-AK-42onVFFB-42D.The air will be drawn into the cooling layer of the fireplace and be completely separated from the combustion casing of thevent-freefireplace.

Cooler outside air will mix with room air, circulating around the firebox to reduce the heat output and bring heated, fresh air into the house to provide a more positive balance.

C-7.INSTALLING THE HOOD.

A black hood is furnished with each model VFFB36/42D fireplace and MUST be installed before the fireplace is used. Failure to do so may create a possible fire hazard. If brass hoods are desired, they can be purchased as an option. Attachment is the same, as our standard black hood.

1.Remove the one top screw and one from each side of the fireplace surround. Be careful not to remove the screen rod from the fireplace, during this procedure.

2.Line up the holes with holes in hood being installed. Insert screws and tighten securely.

EXTENDED HOODS.

If your facing material over 1" in thickness is used to finish this fireplace, you must purchase a different hood that will extend out 2" farther into the room. Follow steps 1 and 2 above for installation. Contact your local dealer for details.
