GENERAL INFORMATION

High Altitude Installation
When installing this unit at an elevation above 2000 feet (in the
United States) it may be necessary to decrease the input rating by
changing the existing burner orifice to a smaller size. Generally,
input should be reduced 4 percent for each 1000 feet above sea
level. However, if the heating value of the gas has been reduced,
this general rule may not apply. Check with local gas utility for proper
orifice size identification.
For Canadian high altitude applications, this appliance is suitable for
installation at elevations between 0 feet (0m) and 4,500 (1,370m)
without change.
When installing this unit at an elevation above 4500 feet (1,370m)
(in Canada), check with local authorities.
Consult your local gas utility for assistance in determining the proper
orifice for location.
