Lesson 2/Learning Event 3
If gasoline is being used to power the boiler, pour No. 2 diesel
fuel oil (one pint per five gallons of gasoline) into the fuel
container to prevent "freezing" of the fuel pump.
40 F. - 190 F.
Water Temperature Gage:
Make visual inspections of hoses and fuel lines for leaks.
Use the following steps to perform during-operation services on the M2 Water
Step 1. Check
the fuel lines and fuel filter
shell for leaks. Check
boiler and water connections for steam and water leakage. Stop operation if
a fuel leak is detected.
Fuel leaks occurring during operation require the operator to
stop the M2 Water Heater immediately.
Failure to do so may
result in fire and injury to personnel.
Visually inspect the water pressure, fuel pressure, and water
temperature gages for normal operation.
Use the following steps to perform after-operation services on the M2 Water
Only run clear water through the M2
Lubricate as required.
