IMPORTANT
When the main fuel valve is opened at the
bottle or tank, there is an immediate trickle of
gas passing through the inside burner bleeder
valve. Light the burner immediately
Check the fuel pressure at the pressure regulator. Too
much pressure for a small asphalt tank will waste fuel.
Too little pressure will increase heating time. Some ex-
perimentation with the pressure will allow you to de-
termine the most efficient fuel pressure to use. The fol-
lowing is a good rule of thumb.
1000-1250 gallon tank- 15 psi
1500-1750 gallon tank- 20 psi
2000-2250 gallon tank- 25 psi
2250-2500 gallon tank- 30 psi
2750 gallon and larger- 40 psi
If necessary, adjust the flame with the bleeder valve
at the burner.
When the LPG burners are operating, the outside of
the fuel line up to the first coil of the burner should
frost over. If no frost forms it is an indication that the
burners are operating on vapor instead of liquid. This
condition must be corrected immediately to prevent
damage to the burners.
If after the lines frost over, the flame starts to die
down and the frost melts off the fuel line, it is likely
that there is moisture in the fuel supply tank. Moisture
in the fuel can form ice crystals that stop the fuel flow.
Your local LPG supplier can add an anti-icing agent to
prevent burner icing.
Open the valve at the supply tank and immediately
light the inside burner. As soon as the burner lights,
open the bleeder valve. No preheating is necessary.
IMPORTANT
It is recommended that two persons be
involved in lighting the first burner. When the
main fuel valve is opened at the tank, there is
an immediate trickle of gas passing through the
inside burner valve. The longer the gas is
allowed to collect in the flue, the more likely
there will be a flashback when the burner is
ignited. Having one person light the burner
while the other opens the main supply valve
will reduce the likelihood of a flashback.
WARNING
To prevent possible burns, always use a torch
to light the burners. Never attempt to light the
burners with a match or pocket lighter.
WARNING
A fully charged dry chemical type fire
extinguisher must be within easy reach
whenever the burners are operating or there is
an open flame near the distributor. Minimum
dry chemical capacity of the fire extinguisher
should be 10 pounds.
