This forced air circulation comfort heating system uses only outside air for combustion, as the burners are completely sealed within the heating chamber. Combustion is discharged outdoors through the wall; this eliminates the expense of a chimney... all vent material is included for walls from 3/4" to 9" thickness. As all direct-vent models operate with no open flame and use only outside air for combustion, they are recommended as garage heaters. Unit comes from factory set up for natural gas. In order to operate on LP (liquid propane), the Williams 7728 LP Conversion Kit must be purchased seperately. Please read this Important Safety Notice.
