Interior Wall Materials:

 

Wall  materials,  such  as  drywall,  should  be  set  flush  with 

the rough front face of the Vent-Free fireplace. This will allow 

for placement of required non-combustible surround material in 

such a way that the surround material can lay flat against the 

finished wall surface and also align with the leading edge of the 

fire brick interior of the Vent-Free fireplace (see 

Figure 15

).

Trim Facings:

 

Parts  of  the  combustible  mantle  assembly  located  along 

the sides of the firebox opening, which project more than one 

and one-half inches (1-1/2”) from the face of the fireplace, shall 

be kept at least eight inches (8”) from the firebox opening.

Adjoining Room Walls:

Interior  wall  surfaces  of  adjoining  room  walls  must  be  at  a 

minimum horizontal measure of twenty four inches (24”) away 

from the finished opening of the Vent-Free fireplace.

Air for Combustion and Ventilation

 

Energy efficient homes require homes to be airtight but at the 

same  time  provide  sufficient  fresh  air  to  breathe.  Fresh  air 

enters  the  home  through  air  conditioning  duct  vents,  around 

doors and windows but also must provide enough fresh air for 

proper combustion on 

all

 fuel-burning appliances in the home.

Exhaust  fans,  fireplaces,  clothes  dryers,  and  fuel-burning 

appliances draw air from the house to operate. You must provide 

adequate fresh air for these appliances. This will insure proper 

venting of vented fuel-burning appliances.

Providing Adequate Ventilation

In accordance with the National Fuel Gas Code NFPA 54/ANSI 

Z223.1,  Section  5.3,  Air  for  Combustion  and  Ventilation,  all 

spaces in homes fall into one of the three following ventilation 

classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The following information will help you classify your space and 

provide adequate ventilation.

Unusually Tight Construction

  The air that leaks around doors and windows may provide 

enough  fresh  air  for  combustion  and  ventilation.  However, 

in  homes  of  unusually  tight  construction,  you  must  provide 

additional fresh air. Unusually tight construction is defined as 

construction where:
a. Walls and ceilings exposed to the outside atmosphere have 

a continuous water vapor retarder with a rating of one perm* 

or less with openings gasketed or sealed and...

b. Weather stripping has been added on openable windows and 

doors and...

c.  Caulking  or  sealants  are  applied  to  areas  such  as  joints 

around window and door frames, between sole plates and 

floors,  between  wall-ceiling  joints,  between  wall  panels,  at 

penetrations  for  plumbing,  electrical,  and  gas  lines,  and 

other openings.

* A perm is a unit of permeance or water vapor transmission, 

the US perm-inch is defined as the passage of 1 grain of vapor 

through 1 square foot of 1 inch thick material in 1 hour under a 

pressure difference of 1 inch of mercury.
If your home meets all the three criteria above, you must provide 

additional fresh air.
