Only specialty hoses rated for use with LP Gas may
be installed with this system. Use of other types of
hose may result in hose failure and leakage. Hoses
must be changed by a trained professional.
NOTICE
The glycol mixture should be changed every second year to
insure maximum corrosion inhibitor effectiveness.
NOTICE
Never allow the heating system to stand empty of glycol.
NOTICE
The LP Gas system must be checked regularly (sug-
gested once a year) by a professional, to ensure
that there are no leaks from connections or hoses.
