Before storing your kerosene torpedo heater for the summer, you need to do these things – • Take off the fuel completely from the tank. Kerosene tends to undergo a chemical transformation and gets damaged over the summer. • Clean off the dirty wick. If the wick is worn out, replace it – follow the manufacturer's instructions. • If the batteries are weak, discard them and clean the heater. Get good batteries, tap their ends, and store them in a dry place. • Store the device and its accessories in moisture-free and dust-free containers. The best thing would be to keep it in the heater in which it came.
