PSI
High Temperature Limit Control
NOTE: This feature is designed as a safety feature only.
It is not to be used for thermostatic control
This feature causes the burners to automatically shut
off when the high temperature limit is reached, (
Figure
6-10 ) The burners will not restart until the material cools
to less than the set temperature limit This feature helps
to prevent overheating the material
NOTE: Burner Control switch is a momentary switch and
will return to the OFF position An icon will display
on the screen when the Burner Control switch
has enabled the burner system controls
DO NOT leave the unit unattended
while heating material . Monitor the Controller
display temperature, as well as the dial or pencil
thermometer, to insure that all equipment is
functioning properly and that the material does not
heat beyond the required spraying temperature,
(see Guideline Temperatures For Liquid Asphalts in
Section 4)
LPG Burner Manual Extinguishing
1 Close the tank valve and allow the fuel to flow to the
burners until they go out
2 Close the pilot and shut-off valves in the lines
3 Wait 5 minutes before relighting to insure there are
no fumes in the flue.
Hot material will turn water into steam
and can cause an explosion .
3 Be sure that flue tubes are covered by at least 8
inches of material Read the tank dipstick If the
amount in the tank is less than the recommended
amount in
Table 6-3 . Tank Contents Chart to
Ensure Flue Tube Coverage , do not use the
burners Using the burners without enough material
in the tank will cause damage to the flue tubes and
could cause an explosion
Never operate the burners if the flue
tubes are not covered with at least 8” (20 .32cm)
of material. The flue tubes can become red hot and
ignite the vapors causing an explosion .

Operating the burners without
circulating the product in the tank can create
explosive fumes . If the product can not be circulated
after 15 minutes of heating, the fuel to the burners
must be turned off, while leaving the blowers running
(15 minutes ON, 15 minutes OFF). Do not try to heat
material again for 30 minutes .
