Installation Codes

The fireplace installation must conform to local codes. Before installing the
fireplace, consult the local building code agency to ensure that you are in
compliance with all applicable codes, including permits and inspections.
In the absence of local codes, the fireplace installation must conform to the
National Fuel Gas Code ANSI Z223.1 (in the United States) or the CAN/CGA-
B149 Installation Codes (in Canada). The appliance must be electrically
grounded in accordance with local codes or, in the absence of local codes with
the National Electric Code ANSI/NFPA No. 70 (in the United States), or to the
CSA C22.1 Canadian Electric Code (in Canada).
This model may be installed in a bedroom or bed-sitting room in the U.S.A. and
Canada.

High Altitude Installations

U.L. Listed gas appliances are tested and approved without requiring changes for
elevations from 0 to 2,000 feet in the U. S. A. and in Canada.
When installing this appliance at an elevation above 2,000 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 the local gas utility.
If installing this appliance at an elevation above 4,500 feet (in Canada), check with
local authorities.
