This is a firebox enclosure for a separately selected, listed vent-free gas burner and log set. It is not a complete gas appliance by itself. Choose a heater whose installation manual allows the available interior space, selected liner and required clearances. The firebox manual limits the installed unvented decorative room heater to 40,000 BTU/h; that limit is not the output of the empty firebox.
| Model | VFS36FB0F |
|---|---|
| Outer width × height × depth | 39-1/4 × 38-1/16 × 23-3/16 inches |
| Framing width × height × depth | 40-3/8 × 38-7/8 × 23-3/8 inches |
| Fuel and ignition | Determined by the separately purchased compatible heater; the empty enclosure has no burner or ignition system |
| Firebox classification | Ventless enclosure for a listed gas-fired unvented decorative room heater |
The firebox is supplied with a black hood. That hood, or the exact approved optional replacement hood, must be installed before operation. A separately purchased compatible vent-free heater and its approved log/media arrangement are required to make a functioning fireplace. Follow both the firebox manual and the selected heater manual. Do not burn wood or modify the enclosure to accommodate a heater that does not fit.
The firebox is vent-free; a chimney or direct-vent pipe is not a required purchase for this enclosure. Local permission to install vent-free equipment and the heater’s combustion-air, room-size and placement requirements must still be checked. Do not infer compatibility solely from a burner’s advertised nominal width: compare its minimum firebox dimensions with the manual’s interior dimensions for the selected lined or unlined configuration.
This SKU is the flush-front Select enclosure. The manual identifies FBB5 blower and VFA2 fresh-air kit as optional accessory choices. VFA2 must be planned and fitted during initial installation. Decorative trim, finishing and approved hood choices remain optional upgrades; an optional fresh-air kit is not a flue or direct-vent system.
Maintain at least 6 inches from the inside of the firebox to a perpendicular combustible sidewall and 36 inches in front. The ceiling must be at least 84 inches above the bottom of the firebox. Combustible top finishing requires the manual’s 3/4-inch clearance. Follow the complete mantel diagram rather than treating a zero-clearance casing as permission to cover the opening or hood.
A flush mantel base adds 3-3/4 inches to the stated framing height. Account for the finished-wall thickness and any supporting panel. When installed over carpeting, tile or another combustible surface other than wood flooring, use the full-width and full-depth metal or wood support panel specified by the manual. Plan gas piping and its shutoff before closing the wall.
