Questions and answers

Darren Sturland

May 7, 2025

We have drained the system for new radiators and the boiler will not start. We have only recently moved to the property so we are unsure what we are doing. Model 60/80

1 comments:

Mr. Anderson

May 19, 2025

The GAH model 60/80 boiler may not start after draining the system for new radiators because the system pressure is likely too low. The pressure gauge should read between 1 and 2 bar. If it's lower, the boiler will not operate. Refill the system to the correct pressure to resolve the issue.

Check that the flue is of the same diameter for its entire length. A flue that steps from one size to another will affect the draw of air resulting in inefficient Burner operation or Burner malfunction.
