Zodiac pool heater runs but causes excessive condensation or steam at the exhaust.

Safety: Exhaust gases are hot and potentially hazardous. Do not touch vent surfaces during operation.

• Check water temperature: Very cold pool water can cause visible steam; this may be normal initially. Monitor if it persists excessively.
• Verify flow rate: Ensure pump speed and valve positions provide adequate flow through the heater to raise outlet temperature and reduce condensation.
• Inspect venting: Confirm vent materials and configuration meet Zodiac and code requirements for condensing or non-condensing operation.
• Look for water at base: If water is dripping from the base or vent joints, internal condensation management may be compromised and should be evaluated by a technician.
