INSTALLATION
IMPORTANT :
The installation drawings in this manual are typical layouts shown as examples of types of layouts 
only. We recommend that you engage a professional plumbing and heating company to ensure 
your installation is suitable for your application, will serve your needs and will conform to all local 
codes.
The Pro-Fab Industries warranty covers the Empyre Pro Series furnace only and does not include 
anything outside of the Empyre Pro Series furnace. Pro-Fab Industries takes NO responsibility 
for faulty installations, etc. DO NOT modify this unit in any way. Any modication will void the 
warranty.
These drawings should help in establishing a list of material required for a typical installation. All 
parts should be available from your Empyre Pro Series provider. Ask your dealer for a parts list.
A regular furnace system is left intact and 
automatically cuts in when the Empyre Pro Series 
Outdoor Furnace runs out of wood, Figure 1.
Note: The existing furnace functions as a standby. 
The aquastat on an in-house furnace should be
