B. Glass Specifications
Hearth & Home Technologies appliances manufactured with
tempered glass may be installed in hazardous locations
such as bathtub enclosures as defined by the Consumer
Product Safety Commission (CPSC). The tempered glass
has been tested and certified to the requirements of ANSI
Z97.1 and CPSC 16 CFR 1202 (Safety Glazing Certification
Council SGCC# 1595 and 1597. Architectural Testing, Inc.
Reports 02-31919.01 and 02-31917.01).
This statement is in compliance with CPSC 16 CFR Section
1201.5 “Certification and labeling requirements” which refers
to 15 U.S. Code (USC) 2063 stating “…Such certificate
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.
A. Appliance Certification
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.
NOT INTENDED FOR USE AS A PRIMARY HEAT SOURCE.
This appliance is tested and approved as either supplemen-
tal room heat or a decorative appliance. It should not be fac-
tored as primary heat in residential heating calculations.
Listing and Code Approvals
F. High Altitude Installations
U.L. Listed gas appliances are tested and approved without
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 orifice 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 elevations
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 orifice size, check with local gas utility.
If installing this appliance at an elevation above 4500 feet
(in Canada), check with local authorities.

G. Non-Combustible Materials Specification
Material which will not ignite and burn are those consisting
entirely of steel, iron, brick, tile, concrete, slate, glass or
plasters, or any combination thereof. Materials that are re-
ported as passing ASTM E 136, Standard Test Method
for Behavior of Materials in a Vertical Tube Furnace
at 750
o C, shall be considered non-combustible materials.
H. Combustible Materials Specification
Materials made of or surfaced with wood, compressed pa-
per, plant fibers, plastics, or other material that can ignite
and burn, whether flame proofed or not, or whether plastered
or unplastered shall be considered combustible materials.
Air infiltration test ASTM:E283-(04). The sample was test-
ed at 1.57 psf (equivalent to a 25-mph windload).
Water resistance test ASTM:E331-00. The test specimen
was tested at the requested test pressures of 8.0 & 25.0 psf.
Structural test ASTM:E330-02. The unit was tested to a
design pressure of 50-psf, a test pressure of 75-psf.
