Heat & Glo LifeStyle Collection • Twilight-II-B • 2108-900 Rev. G • 8/07 4
B. Glass Specifi cations
Hearth & Home Technologies appliances manufactured with
tempered glass may be installed in hazardous locations
such as bathtub enclosures as defi ned by the Consumer
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. Architectural Testing, Inc.
Reports 02-31919.01 and 02-31917.01).
This statement is in compliance with CPSC 16 CFR
Section 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.
A. Appliance Certifi cation
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
factored as primary heat in residential heating calculations.
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 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 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 orifi ce size, check with local gas utility.
If installing this appliance at an elevation above 4500 feet
(in Canada), check with local authorities.
E. BTU Specifi cations
MODEL: Twilight-II-B
LABORATORY: Underwriters Laboratories, Inc. (UL)
TYPE: Direct Vent Gas Appliance
STANDARD: ANSI Z21.50-2003 • CSA2.22-M03 • UL307B
Do NOT use this appliance if any part has been under water.
Immediately call a qualifi ed service technician to inspect the
appliance and to replace any part of the control system and
any gas control which has been under water.
This product is listed to ANSI standards for “Vented Gas
Appliances” and applicable sections of “Gas Burning Heat-
ing Appliances for Manufactured Homes and Recreational
Vehicles”, and “Gas Fired Appliances for Use at High
Altitudes”.
D. Air Infi ltration, Water Resistance and
Structural Tests
The Hearth & Home Technologies Twilight-II-B Indoor/
Outdoor Appliance unit was tested to the following ASTM
standards at the Stork Twin City Testing laboratory.
Test Results
C. Thermal Performance Data
G. Non-Combustible Materials Specifi cation
Material which will not ignite and burn are those consist-
ing entirely of steel, iron, brick, tile, concrete, slate, glass
or plasters, or any combination thereof. Materials that are
reported 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 Specifi cation
Materials made of or surfaced with wood, compressed paper,
plant fi bers, plastics, or other material that can ignite and
burn, whether fl ame proofed or not, or whether plastered or
unplastered shall be considered combustible materials.
Air infi ltration 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.
