Liquid Propane Models
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 moisture
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 on page
14) to liquid pipetrain on heater. Have a quali-
fied gas service man inspect installation to be
sure that everything is installed according to lo-
cal 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
1. Propane vapor models are designed to run di-
rectly off of supply tank or from a separate ex-
ternal vaporizer.
2. Run proper size line (see specifications on page
14) to pipetrain on heater. Have a qualified gas
service person inspect installation to be sure ev-
erything is installed according to local codes and
ordinances.
3. After installation is complete check all connec-
tions for leaks. DO NOT USE FLAME FOR
LEAK TESTING.
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 on page
14) to pipetrain on heater. Have a qualified gas
service man inspect installation to be sure ev-
erything is installed according to local codes and
ordinances.
3. After installation is complete check all connec-
tions for leaks. DO NOT USE FLAME FOR
LEAK TESTING.
Important! Do not use propane tanks which have previ-
ously been used for ammonia unless they have been purged
according to procedures of the National L. P. Association.
Be sure fuel supply system complies with all local
codes for L. P. gas installations. DO NOT USE FLAME
FOR LEAK TESTING.
