Step 4. Open the cover on top of the M2 water heater. Leave the cover open. A water hose, fuel hose,
and electrical power cable assembly are coiled in this storage compartment. On top of the boiler, a
quick-disconnect coupling half connects one end of the water hose to the heater outlet pipe. Do not
disconnect this end of the water hose. Uncoil the water hose and connect the free end of the water hose
to the agitator connector on the upper discharge pipe on the tank unit.
Step 5. See that the HEATER-ON/PURGE-ON switch is in the PURGE-ON position before
proceeding. Remove the fuel hose from the storage compartment.
When using gasoline to power the boiler, pour 1 pint of grade number 2
burner fuel per 5 gallons of gasoline into the fuel container to prevent
seizing of the fuel pump.
Step 6. Remove the fuel hose assembly (Figure 32) from the storage compartment. Connect the fuel
tank plug of the fuel lines to a 5-gallon fuel can.
Use the fuel hose with the 5-gallon can only. Do not use a vehicle gas
tank or a 55-gallon drum as a fuel source. The 5-gallon can controls
vapors and suppresses electrical sparks.
