INSTALLATION
Liquid Propane Models
Deluxe Centrifugal Heater
Fuel Connection
Important! Do not use propane tanks which have previously
been used for ammonia unless they have been purged accord-
ing to procedures of the National L. P. Association.
Be sure fuel supply system complies with all local codes
for L. P. gas installations.
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-
ture that may be present in tank or lines may
freeze when system is used in cold weather. To
avoid this, the usual precaution is to purge the
system with methanol.
2. Run proper size line (see specifications) to liq-
uid pipetrain on heater. Have a qualified gas
service man inspect installation to be sure that
everything is installed according to local codes
and ordinances.
3. After installation is complete check all connec-
tions for leaks with liquid detergent or compa-
rable. Wear rubber gloves and eye protection.
Avoid contact with liquid propane. DO NOT USE
FLAME FOR LEAK TESTING.
Propane Vapor Models
2. Run proper size line (see specifications) to pipe-
train on heater. Have a qualified gas service
person inspect installation to be sure everything
is installed according to local codes and ordi-
nances.
3. After installation is complete check all connec-
tions for leaks.
DO NOT USE FLAME FOR LEAK TESTING.
(See above for other precautions.)
Natural Gas Models
1. Natural gas models are similar to vapor models,
but have a larger orifice to accommodate
lower pressure sometimes found with natural
gas.
2. Run proper size line (see specifications) to pipe-
train on heater. Have a qualified gas service
man inspect installation to be sure everything is
installed according to local codes and ordi-
nances.
1. Propane vapor models are designed to run di-
rectly off of supply tank or from a separate ex-
ternal vaporizer.

3. After installation is complete check all connec-
tions for leaks. DO NOT USE FLAME FOR
LEAK TESTING. (See above for other precau-
tions.)
