In the USA: The appliance may be installed at higher altitudes. Please refer to your American Gas Association
guidelines which state: the sea level rated input of Gas Designed Appliances installed at elevations above
2000 (610 m) feet is to be reduced 4% for each 1000 feet (305 m) above sea level. Refer also to local
authorities or codes which have jurisdiction in your area regarding the de-rate guidelines.
In Canada
: When the appliance is installed at elevations above 4500 feet (1372 m), the certified high altitude
