What is the easiest way to light the hot tub stove?

Start by putting some dry wood at the bottom of the stove along with lighter fluid, kindling or wood so that you start the fire under the flue and not under the stove door. Then light it and check that it burns down in the stove. Check that there is smoke coming out of the flue (chimney), if so the draught will be in the right direction and you can start adding more fuel. Gradually feed the stove with dry wood, preferably pushing the wood before adding new fuel so that it gets further into the stove. This will allow more fuel to be added and heating will be faster.
