this caution
may result
in damage
to tire
furnace
and other property
damage.
Do not use ethylene
glycol
(Prestone
II antifreeze
coolant
or
equivalent).
Failure
of plastic components
may occur.
Since the furnace
uses a condensing
heat exchanger,
some water
will accumulate
in the unit as a result of the heat transfer
process.
Therefore.
once it has been operated,
it cannot
be turned
off and
left off for an extended
period
of time when
temperatures
will
reach
32°F
(0°C)
