Location of Plumbing & Electrical Lines
To locate the connection points for plumbing and electrical lines you will need to open
the back hull door. The plumbing and electrical lines for your unit must be installed
underground in a water tight pipe or other suitable insulation means. The water lines
must be buried below the frost line to prevent freezing. Verify the correct depth
according to local building codes prior to installation.
The installation will require a trench wide enough to accommodate a 4” water tight pipe
or other insulation means. All plumbing and electrical lines should be installed inside
the 4” water tight pipe or other insulation means for a standard installation.
This pipe will run from the rear of the unit to the location to be heated. Contained inside
the 4” watertight pipe is 2 water lines and electrical supply wire. The listing below
describes each line and related function.
1. One 1” water supply line to heating system
2. One 1” water return line from heating system
(Note: The supply and return lines must be 1” pipe .)
3. One #12/2 w/gnd NM type UF underground wire
