About This Item

The Pentair Metal Flue Collar (77707-0077) is the OEM replacement 4-inch x 8-inch flue collar designed for vertical negative-pressure venting on Pentair pool and spa heaters.

⚠️ IMPORTANT: LICENSED PROFESSIONAL INSTALLATION REQUIRED
Gas heater venting components must be installed or replaced by a licensed pool professional or qualified HVAC technician. Do not attempt to service gas venting or combustion components without proper certification.

This metal flue collar is specified for vertical negative-pressure venting installations. Replacing a damaged or corroded flue collar restores a proper sealed connection at the vent transition point, preventing combustion gas leakage at the heater cabinet.

Pro Tip

Before ordering, confirm your heater's vent configuration — this collar is specified for vertical negative-pressure venting only. Check the vent collar size stamped on your existing part or listed in your heater's installation manual to confirm the 4 in. x 8 in. dimension matches your unit. All venting work must be completed by a licensed pool professional or qualified HVAC technician.
