Base Price shown is for FIREBOX with MULTI-TONAL GREY CERAMIC FIBER LINER ONLY. A Burner and Log Set are  required. A Blower Fan is also available but not required! The price displayed will update based on your selections. If you need help designing your firebox, please contact us.
Maximize the heat in your room with a ACUF36-BD vent free, radiant firebox. It offers a louverless, clean front and includes a multi-tonal grey dual-sided ceramic fiber liner. Yes, the liner is reversible! One side of this liner offers a traditional brick pattern, while the reverse side features a herringbone pattern. Both patterns feature grey brick tones for a slightly different traditional fireplace look. It offers a beautiful 36" wide viewing area. With a log set (sold separately) of your choice, you will warm up quickly. No chimney is required for a vent free fireplace and since it is also a zero clearance firebox, it can be installed flush against virtually any surface including drywall or wood. Plus this also gives you the flexibility of installing on an interior or exterior wall!
 
With a vent free firebox, fresh air is drawn in at the bottom of the firebox, and warmed air is expelled into the room from the top. The ACUF36 firebox features an angled top design to help direct the warm air out for maximum efficiency. A blower (GFK-160VF) can be added to help circulate the warm air.
 
The ACUF36 firebox will accept most 24" and 30" vent free log sets and burners (sold separately). Please confirm all minimum dimensions required for specific burners and log sets. With zero clearance, the firebox can be installed flush against any surface like drywall or wood.
 
The ACUF36-GD firebox offers a clean face and a large 36" x 27" viewing area. Included with the firebox is a black hood.

  • 32-7/8" Front Width
  • 25-1/2" Front Height
  • 24-3/8" Rear Width
  • 22-5/8" Rear Height
  • 15" Deep
Framing dimensions are 42-1/2"w x 34-1/4"h x 19-3/4"d.

The ACUF36-GD will accept Monessen 24" or 30" Log Sets (sold separately). Below are the Monessen Log Set options available for this firebox. With zero clearance, the firebox can be installed flush against any surface like drywall or wood. Vent Free Natural Blaze Burners are available for use with each of these log sets:
 
 
Additionally, Monessen offers Natural Blaze burners with Natural Blaze Technology. This technology helps provide taller, more lively flames for a truly realistic fire in your vent-free firebox. Beautiful yellow flames are instantly achieved every time your burner is switched on. Available burners for the 36" firebox include:
  • Millivolt Valve (NB2430PV, NB2430NV) - standing pilot with on/off switch and manual variable flame height control  and remote ready (remote sold separately)
  • Electronic Ignition with Intellifire Plus System (NB2430PIF, NB2430NIF) - intermittent pilot/electronic ignition, 3 step flame adjustment and Touch Screen Thermostat Remote included.
With a vent free firebox, fresh air is drawn in at the bottom of the firebox, and warmed air is expelled into the room from the top. The Monessen fireboxes feature an angled top design to help direct the warm air out for maximum efficiency. A blower can be added to help circulate the warm air.

An optional outside air kit is also available for vent free fireboxes. The AKD introduces fresh, outside air into the firebox. An outside air kit is recommended as an accessory when installing a vent free appliance into newer, more air tight construction for an adequate supply of fresh air. Some local building codes may require an outside air kit.
 
Additionally, an Accent Lighting Kit (MONAL-VF) is also available separately.
 
A log set and burner are required. Check out our selection of available log sets.
 
While there are no decorative pieces required for this firebox, several mantel cabinets are available (sold separately) to help customize your fireplace look.
