HIGH ALTITUDE INSTALLATION
Your Vanguard direct-vent fireplace has been CSA tested and
approved for operation at altitudes in the USA from 0-2000 ft. and
in Canada from 0-45000 ft.
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. Reduce 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 elevation above 4500 feet (in
Canada), check with local authorities.
Consult your local gas company to help determine the proper orifice
for your location.
For assistance with any high altitude installation contact DESA
International’s Technical Service Department at 1-866-672-6040.
