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
UL 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.
