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).
These models may be installed in a bedroom or bed-sitting room in the U.S.A.
and Canada.
High Altitude Installations
U.L. Listed gas fireplaces are tested and approved for elevations from 0 to
2,000 feet in the U.S.A. and from 0 to 4,500 feet in Canada.
When installing this fireplace at an elevation above 2,000 feet (in the United
States), it may be necessary to decrease the input rating by changing the
existing burner orifice to a smaller size. Input should be reduced four percent
(4%) for each 1,000 feet above sea level, unless the heating value of the gas
has been reduced, in which case this general rule will not apply. To identify the
proper orifice size, check with the local gas utility.
When installing this fireplace at an elevation between 2,000 and 4,500 feet (in
Canada), the input rating must be reduced by ten percent (10%).
When installing this fireplace at an elevation above 4,500 feet (in Canada),
check with local authorities.
Consult your local gas utility for assistance in determining the proper orifice for
your location.
