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

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.
