About This Item
The Pentair 77707-0086 is the OEM stainless steel appliance adapter for horizontal or vertical positive pressure venting. Manufactured by HeatFab (a Selkirk Corp. brand), this adapter is the factory-specified component for connecting the heater's exhaust system to positive pressure vent configurations.
⚠️ IMPORTANT: 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. Improper venting installation creates a risk of carbon monoxide exposure and fire hazard.
This venting adapter supports both horizontal and vertical vent routing configurations in positive pressure applications. Positive pressure venting systems actively push combustion gases out of the appliance, requiring components rated and designed for that pressure differential. Using a non-rated or incorrect adapter in a positive pressure application is a safety hazard — this part is the correct OEM specification for that application.

Pro Tip
Before ordering, confirm your heater's venting configuration — positive pressure and standard atmospheric vent adapters are not interchangeable. Check the venting label on your heater or consult the installation manual to verify that your system is a positive pressure application. If you are unsure, have a licensed HVAC or pool heating technician confirm the venting type before purchasing this component.
