I have an orange flame in all my gas appliances (gas furnace, gas water heater, and gas stove) and cannot seem to determine the cause.
So far, I have had the gas company come out. I had an appliance tech look at our stove, and tomorrow, I am having a guy check it out on the furnace.
When the gas company (XCel energy) checked it out yesterday, they measured the pressure on with appliances running and without. In both situations things measured fine. Our meter was making some noise, so the gas company put in a new one. They also measured Carbon Monoxide (CO) levels and found nothing wrong throughout the house.
Today, I had an appliance tech come check it out. He checked our stove and he said everything checks out fine. He also checked CO levels throughout the house. In any case, his tests revealed no cause for the issue.
Tomorrow, I am having a furnace guy come in, this is the big one, because the orange flame seems to be causing the furnace to short cycle.
My hunch is that something must be entering the line elsewhere. No gas inside the house makes me think the natural gas lines coming into the house have the problem. However, the gas company says everything is fine.
What I am looking for
Anyway, I am seeking direction on the course of action to take here. From my perspective, I cannot see how all three appliances would have issues that cause an orange flame at the same time. This seems very clear that something is going on with the gas lines, but I am at a loss of who to call to actually fix the core issue.
