I NEVER said this was going to be an EASY "do"

....I have hands/arms like ham hocks and I managed to access the tap through the hole where the stove was. If you try n pull the sink, you're probably going to break one of those undercounter screw type anchoring devices... NOT TO MENTION to reach at least ONE of the four, you are going to have to remove that furnace anyway. Re an re of the stove requires only a minimum of effort and yes, you DO have to remove the gas line

. You must remember to be sure the
propane valve is shut off first and before you re-install the gas line to the stove, REMEMBER to wrap the male end with gas fitters tape (similar to plumbers tape) and be sure to do a SOAP test of the joint too check for
leaks. Sounds kinda daunting, but REALLY, its not!!
