INSTALLATION
Your Sun Valley B-vent freestanding stove
and burner system has been AGA tested and
approved for elevations from 0-2000 feet and
CGA certified for elevations from 0-4500 feet.
When installing this stove and burner sys-
tem at an elevation above 2000 feet (in the
USA), you may need to decrease the input
rating by changing the existing burner ori-
fice to a smaller size. Reduce input 4% for
each 1000 feet above sea level. Check with
your local gas company for proper orifice
size identification and proper orifice for
your location.
When installing this fireplace at an eleva-
tion above 4500 feet (in Canada), check
with local authorities.
For assistance with any high altitude installa-
tion contact DESA International’s Technical
