B. Glass Specifi cations
Hearth & Home Technologies appliances manufactured
with tempered glass may be installed in hazardous loca-
tions such as bathtub enclosures as defi ned by the Con-
sumer Product Safety Commission (CPSC). The tempered
glass has been tested and certifi ed to the requirements
of ANSI Z97.1 and CPSC 16 CFR 1202 (Safety Glazing
Certifi cation Council SGCC# 1595 and 1597. Architectur-
al Testing, Inc. Reports 02-31919.01 and 02-31917.01).
This statement is in compliance with CPSC 16 CFR Sec-
tion 1201.5 “Certifi cation and labeling requirements”
which refers to 15 U.S. Code (USC) 2063 stating “…Such
certifi cate shall accompany the product or shall otherwise
be furnished to any distributor or retailer to whom the
product is delivered.”
Some local building codes require the use of tempered
glass with permanent marking in such locations. Glass
meeting this requirement is available from the factory.
Please contact your dealer or distributor to order.
Note: This installation must conform with local codes. In the
absence of local codes you must comply with the National
Fuel Gas Code, ANSI Z223.1-latest edition in the U.S.A. and
the CAN/CGA B149 Installation Codes in Canada.

WARNING
NOT INTENDED FOR USE AS A PRIMARY HEAT SOURCE.
This appliance is tested and approved as either supplemen-
tal room heat or as a decorative appliance. It should not be
factored as primary heat in residential heating calculations.
D. High Altitude Installations
U.L. Listed gas appliances are tested and approved with-
out requiring changes for elevations from 0 to 2000 feet in
the U.S.A. and Canada.
When installing this appliance at an elevation above 2000
feet, it may be necessary to decrease the input rating
by changing the existing burner orifi ce to a smaller size.
Input rate should be reduced by 4% for each 1000 feet
above a 2000 foot elevation in the U.S.A., or 10% for el-
evations between 2000 and 4500 feet in Canada. If the
heating value of the gas has been reduced, these rules
do not apply. To identify the proper orifi ce size, check with
the local gas utility.
If installing this appliance at an elevation above 4500 feet
(in Canada), check with local authorities.
