11. Always shut off burners using the main
shutoff valve on the supply tank.
12. To prevent possible burns, always use a
torch to light the burners. never attempt
to light the burners with a match or pocket
lighter.
13. Light inside burner first. Do not reach across
a lighted burner to relight inside burner.
14.
Check overflow tube for restrictions
.
15. When heating, temperatures within the tank
can vary. Shut the burners off when the
thermometer reaches a reading 10ºF lower
than the desired temperature. Continue
to circulate and monitor temperature until
temperature stabilizes. Add remaining heat
by operating burners for short periods,
monitoring stabilized temperature after each
period.
16. Always have a dry chemical type fire
extinguisher available and in good condition.
IMPORTANT
Calibration of thermometers should be
verified to be 2% of full scale reading
annually.
Certification can be accomplished by a
qualified laboratory or by comparing stabilized
dial readings to the pencil thermometer
reading. Replace any thermometer that does
not meet the +2% accuracy requirement.
Propane Requirements
Use only liquid withdrawal type supply tanks for
your propane burners.
Two types of propane supply tanks are avail-
able: tanks for liquid type burners and tanks for
vapor type burners. The propane burners on your
Etnyre Distributor require a supply tank for liquid
type burners. Liquid type burners will operate from
a vapor withdrawal tank, however the amount of
heat delivered will be dramatically reduced, and
the life of the burner will be shortened.

Liquid Propane Gas (LPG)
Burners
IMPORTANT
Circulating the asphalt in the tank while
heating is recommended for faster heating
and reduced carbon formation on the flues.
Only when the asphalt pump is
Frozen
is it
acceptable to operate the burners without
circulating asphalt in the tank. However, if the
asphalt pump is frozen, carefully apply heat to
the pump and start circulating the material as
soon as possible.
WARNING
1. Residual fuel in Propane burners will support
a flame for several minutes after the fuel
flow has been shut off. After using Propane
burners, confirm that all flame has been
extinguished before attempting any operation
that could release flammable vapors. Failure
to ensure that the flame is completely
extinguished could result in an explosion or
fire that can cause injury or death.
2. Position unit broadside to wind whenever
possible to prevent volatile fumes from
drifting toward burners
3. Flues MUST be covered by a minimum of 6
inches (150mm) of material when the burners
are in operation.
4. Do not remove material from tank in any
manner when the burners are in operation.
5. Do not drive unit when burners are operating.
6. Do not operate burners if tank is damaged
or leaking.
7. When burners go out, allow flues to ventilate
for several minutes before relighting burners.
8. Do not heat material beyond the manufacturers
recommended temperature.
9. Do not heat material over 200ºF (95ºC) if
moisture is present in tank.
10. To prevent possible burns from material
overflow, allow sufficient space in tank for
expansion of material when heating.
