1. LP models are designed to run on liquid pro
pane, with liquid draw from the propane tank.
Avoid using propane supply tanks that have
been used for vapor draw for long periods of
time. When using liquid draw systems any mois-

freeze when system is used in cold weather. To
avoid this, the usual precaution is to purge the
system with methanol.
