This burner was designed to operate with domestic
fuel with viscosity at 20
°
C of between 2 and 7.5 cSt.
It is known that fuel viscosity greatly varies at low
temperatures. It is recommended that the tank and fuel
inlet and return pipes are protected against the cold.
Fuel of 5 cSt viscosity at 20
°
C switches to 10 cSt
viscosity at 0
°
and 15 cSt viscosity at -10
°
. Nozzle
spraying and flow are then fully changed and there is
a risk of clogging and breakdown.
