You must use underground insulated pex pipe for transferring the heated water from the boiler to
the home.

(4” drain tile)
& Platinum 4 wrap (
5”
drain tile) insulated pipe is available for purchase through
Nature’s Comfort
or your dealer. It may
contain twine for pulling electrical wire. If possible, do this with the pipe laid out straight for ease of
pulling.
CALL YOUR LOCAL MISS DIG HOTLINE BEFORE YOU DIG TRENCHES!
Bury the underground insulated pipe below frost lines (or just above water table level) and keep
underground as it enters the house. The depth of the trench varies in different regions of the
country. Be completely sure about the correct depth needed before the insulated pex pipe is
installed underground.
Contact your local building inspector’s office for this information.
Make sure
to seal around the corrugated pipe to prevent water from entering. If conditions require the pipe to
be above ground for entering the home, make sure to insulate thoroughly.
Note:
If only one color of PEX pipe is used, label the water lines or connect and test them before
back filling over pipe and lines. If you have rocky ground, make sure you use clean fill or place
straw or landscape fabric around the pipe before back filling, giving extra protection against
punctures.
If more than one building is to be heated, additional pipe and pump must be installed.
