Heater cabinet shows rust and corrosion, especially near the base and flue

Safety: Turn off power and gas before performing maintenance.

• Address condensate issues: For condensing SunHeater models, ensure the Condensate Drain System is working and not dripping onto the cabinet.
• Clean and treat rust: Light surface rust can be cleaned with a wire brush and treated with a rust-inhibiting primer and high-temperature paint.
• Improve environment: Keep pool chemicals stored away from the heater. Avoid directing chlorinated water spray onto the cabinet.
• Inspect structural integrity: If rust has perforated the cabinet or compromised supports, have a technician evaluate whether repair or replacement is necessary.
