1.0 Introduction  

The  following  provides  instructions  for  the installa-
tion and operation of the Stone Age Fireplace, manu-
factured  by  Stone Age  Manufacturing,  Collinsville, 
Oklahoma. 

Three generations of fireplace knowledge and expe-
rience have gone into the design and construction of 
the New Age series fireplaces.   New Age Fireplaces 
are manufactured to comply with UL127 for the US, 
and ULCS610 for Canada.   They are also manufac-
tured to comply with ICC-ES AC156 meeting struc-
tural design requirements for Earthquake Testing at a 
compliance level of Sds = 2.5g.  The ICC-ES AC156 
complies with 2010 American Society of Civil Engi-
neers  (ASCE)  7-10,  2009  International  Building 
Code  (IBC),  2010  California  Building  Code  and 
2012  ICC-ES  AC156.      Assembly  and  Cutaway 
views of a NA72IND fireplace are shown in Figure 
1.   

 

 

 

Because  of  structural  modifications  required  in  an 
existing home, it is recommended that this fireplace 
be installed by a professional installer, or by a build-
er  in  new  construction.    Installation  by  a  non-
qualified person may negate the warranty. 

Keep these instructions for future use.  

2.0 Description 

The  fireplace  is  delivered  as  a  kit  with  all  compo-
nents necessary to complete the installation.  The kit 
is configured for a flue chimney, but a special adapt-
er is available for a metal chimney.  Component ar-
rangement,  some  of  which  is  optional,  is  shown  in 
Figure 2.  Components are shown in Table 1.  Speci-
fications  and  installation  dimensions  are  shown  in 
Table 2. 

A  completed  installation  should  include  the  follow-
