HIGH ALTITUDE INSTALLATION
Your Vanguard direct-vent fireplace has
been CSA/AGA tested and approved for
elevations from 0-2000 feet and CGA certi-
fied for elevations from 0-4500 feet.
When installing this fireplace at an elevation
above 2000 feet (in the USA), you may need
to decrease the input rating by changing the
existing burner orifice to a smaller size. Re-
duce input 4% for each 1000 feet above sea
level. Check with your local gas company for
proper orifice size identification.
When installing this fireplace at an eleva-
tion above 4500 feet (in Canada), check
with local authorities.
Consult your local gas company to help de-
termine the proper orifice for your location.
For assistance with any high altitude installa-
tion contact DESA International’s Technical
Service Department at 1-800-DESA-LOG
(1-800-337-2564).
