Frequently Asked Questions

Q. I have a customer who complains of having soot particles on the floor around the boiler and other places in the basement. The fire is clean. What is the reason for this?

1. Make sure that you have adequate chimney draft so that there is not a back-pressure in the smoke pipe when the burner starts. This type of complaint occurs with a long smoke pipe between the boiler and the chimney. If the smoke pipe does not have enough pitch, there may be a back-pressure at the boiler connection even with sufficient chimney draft.

2. Check for an obstruction at the point where the smoke pipe enters the chimney.

3. Cement up all leaks in the boiler setting where soot might come out on the start.

4. Install a delayed opening solenoid valve or ProTek valve in the nozzle line to make smoother starts.
