Fuel Piping Guidelines
Fuel piping can be installed in sections as dryer is erected, or after dryer is complete. Usually top two (2)
sections of fuel piping are installed after fans are installed.
Fuel piping enters dryer through a dryer window. Plan fuel piping so it will terminate as near as possible
to where fuel train will be on foundation.
Seal all threaded pipe connections with heavy duty pipe sealing compound. Fuel piping must be airtight
and satisfy any hazard requirement for the site.
Check all fuel piping is level or plumb.
Check all fuel piping is secured tightly to dryer.
