The Sight Glass / Inspection Window on Your Raypak Boiler

The sight glass is an inspection window that lets a technician view the burner flame to confirm clean combustion. A sooted or cracked sight glass hides combustion problems and can leak flue gas if its seal fails.

On Raypak systems — including models such as XTherm, XVers, MVB — a failing sight glass / inspection window often shows up as no heat or related symptoms. We diagnose it precisely and install the correct genuine Raypak part.
