High Altitude Installation
Your DESA
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.
