MINIMUM CLEARANCE TO 

COMBUSTIBLES

Back and sides of firebox 

1" min.

Adjacent wall 

12" min.

Chimney outer pipe surfaces  2" min.

Bottom of firebox to floor 

0" min. 

  WARNING:  Do  not  block 

required  air  spaces  with  insu

-

lation  or  any  other  material. 

Do not obstruct effective open

-

ing* of firebox with any type of 

facing  material.  Combustible 

material must not be in contact 

with black front face of firebox. 

 

*

(The  effective  opening  is  considered 

the  opening  where  actual  heat  output 

may occur.)

MANTEL CLEARANCES

Woodwork  such  as  wood  trims,  mantels  or 

any other combustible material projecting from 

the front face must not be placed within 9" of 

firebox effective opening. 

Combustible materials above and projecting 

more than 1

" from the firebox front face 

(see Figure 4, page 5) must not be placed less 

than 12" from effective opening of the firebox 

(NFPA STD 211, Sec. 7-3.3.3).
Mantels  or  any  other  combustible  material 

may  also  come  up  to  the  side  edge  of  the 

black  metal  face  of  the  firebox  only  if  the 

projection from the front face falls within limits 

shown in Figure 5, page 5.

SELECTING LOCATION

To  determine  the  safest  and  most  efficient 

location  for  the  firebox,  you  must  take  into 

consideration the following guidelines:
1.  The location must allow for proper clear-

ances.

2.  Consider a location where the heat output 

will not be affected by drafts, air condition-

ing ducts, windows or doors.

3.  A  location  that  avoids  the  cutting  of 

joists or roof rafters will make installation 

easier.

4.  If an outside air kit is to be installed, ac-

cessibility to outside combustion air must 

be considered. This can also be achieved 

through  a  vented  crawl  space  in  some 

cases  (see 

Optional  Outside Air  Kit

  on 

page 6).

5.  Do not connect this firebox to a chimney 

system other than a DESA Heating, LLC 

chimney system.

6.  Install in an area providing ventilation and 

adequate combustion air.

7.  Due to high temperatures, do not locate 

this firebox in high traffic areas or near 

furniture or draperies.

8.  Provide  adequate  clearances  around 

air  openings  into  combustion  chamber. 

NEVER obstruct front opening of firebox 

or flow of combustion and ventilation air.

9.  Do not locate in or near an area where 

gasoline or other flammable liquids may 

be stored. The firebox area must be kept 

clear  and  free  from  these  combustible 

materials.

The typical installation for this fireplace is a 

projected installation which allows you to ex-

tend the fireplace any distance into the room. 

A projection may be ideal for a new addition 

on an existing, finished wall.
