Get one of those long lighters and open it up. Pull out the trigger parts, wires, butane bottle, and hose with the metal tip. Not all lighters are same; in mine I had to keep a plastic slide switch that opens the fuel valve. You may have to make yours a little differently to function.

Bend a pipe bracket and attach it to the side of the handle so that the flame will burn just under the copper cap or boiler.

Insert the piezo clicker into the handle to make a trigger; this is what makes the spark to ignite things. Ground the black wire to the barrel and the long white wire gets routed to the ignition point under the boiler.

Screw a piece of leather to the handle and wrap it around the back to the other side. Fit the butane bottle in there and attach the leather again with a screw. This should hold the tank snuggly, but also let it slide a little. The slide switch to open the fuel valve hangs nicely on the leather strap. To turn on the gas you just push the butane bottle down a little until you hear the hissing; to turn it off you slide the tank up.

Now route the fuel hose and metal tip to the newly attached bracket under the boiler. Wrap the white spark wire around the base of the metal tip. Attach it in the hole with a twisty tie or something and use pliers to bend it so the flame base will be 1/4" under the boiler. The spark should jump from the metal tip to the bottom of the boiler, if it doesn't adjust the bracket until it happens.
