Stop in for a cup of coffee

So took heater apart, My landscape contractor put a post for a timer right in the way to get the heater apart!!! In concrete. Was a lot more difficult then it shroud have been. 3 Rats in there, all crispy. AND a huge nest. Cleaned it all out, inspected the entire heater for more rodents, reassembled it, still same problem, sans the foul smelling smoke. Needs a new Flame sensor, Thermocouple. Ordered it......
