Stone Age Indoor Fireplace
1.0 Introduction
The following provides instructions for the installa-
tion and operation of the Stone Age Fireplace,
manufactured by Stone Age Manufacturing, Col-
linsville, Oklahoma.
Three generations of fireplace knowledge and ex-
perience have gone into the design and construc-
tion of the NA 36, 42 and 48 fireplace. These
fireplaces are UL127 certified.
Because of structural modifications required in an
existing home, it is recommended that this fireplace
be installed by a professional installer, or by a
builder in new construction. Installation by a non-
qualified person may negate the warranty.
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
adapter is available for a metal chimney. Compo-
nent arrangement, some of which is optional, is

1. Specifications and installation dimensions are
shown in Table 2.

The Stone Age Fireplace has been tested and listed
in accordance with UL 127 standards and is listed
by OMNI-Test Laboratories, Inc. for installation
and operation in the United States and Canada as
described in this manual.
This fireplace is designed to supplement your cur-
rent heating system. It is not designed to be used a

quired by local codes are obtained before installa-
tion in an existing home.
