Never ignite the burner or run the tank indoors. Take it outside.
Always wear safety glasses. The boiler can flare during burner ignition. Things -can- break and go flying.
Note the cylinder cap on one of my engines is bolted down. It popped off during a run. Heck of a surprise & a pain to repair. It'd be a far bigger pain though should someone get hurt. So ALWAYS wear safety glasses & keep a fire extinguisher handy.
Open top and bottom of displacement lubricator. Put a rag underneath to catch any draining water. Close bottom port & add steam oil. Tighten top port.
Add drops of normal engine oil to steam engine lubrication cups. Make sure engines can turn freely & aren't stuck from dried oil/etc...
Remove turret. Verify fuel tank valve closed off, and union nuts on fuel tank & burner are tight. Fill tank with propane/butane camping fuel.
Boil some distilled water. Avoid "purified" or tap water because minerals will foul the boiler sight glass. There is some argument from people about what is best. Pure distilled water can be slightly corrosive. Therefore some suggest adding a -small- amount of tap water to the distilled. Some people prefer rain water.
Remove boiler safety valve & use small funnel to fill boiler with boiled water until sight glass 1/4" from full. Replace safety valve & tighten.
Here we go! Ignite a utility lighter. Matches aren't a good idea here.
Open the fuel tank valve & touch the lighter to the boiler funnel. If the lighter goes out, or boiler doesn't ignite immediately, close the fuel valve. Wait for the fuel gas to dissipate before retrying.
The burner should ignite with a pop, followed by a steady quiet roar. It takes several minutes for the boiler to reach pressure. Reinstall the turret, turn on the r/c transmitter, then the tank power switch.
Once the pressure gauge reaches 25 to 30 psi, open the boiler steam valve & have fun!
Check the boiler sight glass periodically. When the water level touches bottom, turn off the fuel gas.
Open the boiler blow down valve below the sight glass & allow pressure out from the boiler.
Remove the safety valve. Remove turret & turn tank over to finish draining. Do this while the boiler is still hot if possible. Leave the safety valve off so remaining water can evaporate. Never leave standing water in the boiler.
Drain the exhaust condensation tanks. Use syringe if needed.
Clean up any water & oil around the engines.
Live steam is messy, but so much fun!
