tices and codes should be
used when working with a
heater. Refer to the National
Electric Code Standard Hand-
book by the National Fire Pro-
tection Association. A quali-
fied electrician should make all
wiring installations.
IMPORTANT! Do not use pro-
pane tanks that have previ-
ously been used for ammonia
unless they have been purged
according to procedures of the
National L.P. Association.
Fuel supply system must
comply with local codes for L.P.
gas installation.
1. Propane vapor models are de-
signed to run directly off of a

2. Run proper size line (see speci-
fications on page 6) to pipe train
on heater. Have a qualified gas
service person inspect installa-
tion to be sure that everything
is installed according to local
codes and ordinances.

1. L.P. models are designed to run
on liquid propane 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 moisture that may
be present in tank or lines may
freeze when system is used in
cold weather. To avoid this situ-
ation, purge the system with
methanol.

fication on page 6) to liquid pipe
train on heater. Have a qualified
