About This Item
The Pentair Blower/Adapter Plate Gasket Kit (77707-0011) is the OEM replacement gasket kit for the burner system on Pentair Max-E-Therm and MasterTemp pool and spa heaters.
⚠️ IMPORTANT: KIT LISTING — MULTIPLE PIECES INCLUDED
This listing is a kit, not a single gasket. It includes Item Nos. 8, 9, 10, and 12 from the Pentair burner system assembly diagram. Confirm all required items against your heater's exploded parts diagram before ordering.
⚠️ IMPORTANT: HEATER COMPONENT — LICENSED PROFESSIONAL INSTALLATION REQUIRED
Gas and electrical heater components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service gas or high-voltage components without proper certification.
The blower and adapter plate gaskets seal the interface between the blower assembly and the burner tray on Max-E-Therm and MasterTemp heaters. When these gaskets degrade, combustion gases can escape the sealed burner chamber, reducing heating efficiency and creating a potential safety hazard. Replacing the full gasket kit restores the airtight seal required for proper burner operation.

Pro Tip
When replacing the blower/adapter plate gaskets, cross-reference Item Nos. 8, 9, 10, and 12 against your heater's exploded parts diagram to confirm each gasket position before disassembly. If your heater has been running with a combustion or exhaust odor near the burner compartment, inspect all four gasket positions — deterioration is rarely limited to a single piece. Have your licensed technician replace the full kit rather than individual gaskets to restore a complete seal in one service visit.
