When installing a non-high altitude fireplace
at an elevation above 2,000 feet (610 m) (in
the USA), you may need to decrease the input
rating by changing the existing burner orifice
to a smaller size. Reduce input 4% for each
1,000 feet (305 m) above sea level. Check
with your local gas company for proper orifice
size identification.
When installing this fireplace in Canada at an
elevation above 4,500 feet (1,372 m), Check
with.local.or.provincial.code.authorities.
