11.2.10 Natural/Propane Gas Conversion
NeoTherm LC’s can easily be converted from
natural to propane gas or from propane to natural
gas. If a gas conversion is performed, the unit must
be identified with the appropriate gas labels and a
conversion sticker to allow technicians performing
maintenance in the future to properly identify the gas
type of the appliance.
11.2.11 Condensate Trap
A condensate drain trap is included with the
NeoTherm LC and is designed to drain the boiler of
condensate. The vent condensate should be drained
through a drain tee located in the vent line. This will
help prevent excessive condensate from entering
the boiler condensate trap and preventing the boiler
from operating.
Connect a 3/4” PVC pipe between the drain
connection and a floor drain (or condensate pump if
a floor drain is not accessible).
The condensate drain must be installed to prevent
the accumulation of condensate. When a condensate
pump is not used, the tubing must continuously
slope downward toward the drain with no spiraling.
Consult local codes for the disposal method.
Caution
Condensate is mildly acidic (pH=5), and may
harm some floor drains and/or pipes, particularly
those that are metal. Ensure that the drain,
drainpipe, and anything that will come in
contact with the condensate can withstand the
acidity, or neutralize the condensate before
disposal. Damage caused by failure to
install a neutralizer kit or to adequately treat
condensate will not be the manufacturer’s
responsibility.

11.2.12 Battery (Date and Time Back-Up for
Touchscreen Display)
The touchscreen does have an internal battery for
back-up of the date and time settings. To access the
battery, the front panel and the touch screen display
must be removed so that the small plastic door on
the back of the touchscreen can be accessed.
The battery is a CR2032 ‘coin type’ battery and
has an expected shelf life of 10 years.
