First inspected the incoming power supply to the furnace and was not receiving the 120 V that it needs to fire off. Thankfully the electricians were on site also and help me look into it and what we found was we were getting intermittent power which ended up being a loose neutral wire in the breaker box the electrician tightened up the loose neutral wire and I got the furnace to turn on. Lastly checked out the fireplace and got it to turn on as well. So the furnace and fireplace had nothing to do with the previous work that I had done when installing the new gas line for the range.
