I was here to replace the gas valve in the furnace. I set up the new gas valve to lp. I replaced the gas valve and wired it to the furnace. Cycled the furnace and set the gas pressures. I checked the temperature rise and it’s at 55 which is good. Checked for gas leaks, found a leak and fixed the leak. The furnace is operating properly at this time. No charge, part is under warranty.
