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 (natural gas and propane) can be installed in a bedroom (in the United
States) which has a total volume of unconfined space appropriate to the particular
installation. Refer to the National Fuel Gas Code ANSI Z223.1/NFPA54 (current
edition). The Uniform Mechanical Code - (current edition), and local Building
Officials for the options allowed in obtaining an effective bedroom volume of
unconfined space.
This model (natural gas and propane) can be installed in a bedroom (in Canada)
if a thermostat (Model WH-STAT) is installed with the unit. Consult local code
authorities. Detailed installation instructions for Model WH-STAT are included
with the kit.
High Altitude Installations
U.L. Listed fireplaces are tested and approved for elevations from 0 to 2,000 feet
in the U.S.A. and are tested and approved for elevations 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.
