Fig. 15  Typical buried piping system

Use the following for buried water piping and greasy waste lines . note that all connections 
must be aboveground and that no splices/tees are allowed . Develop a bill of materials from 
the connection kits in this table .

The FTC-XC power connection and end 

seal kit is for use with XL-Trace heating 

cable that is run through conduit to a junc-

tion box . Materials for one power connec-

tion and end seal is included in the kit .
