About This Item
The Pentair Direct Air Intake Duct Kit (474845) is the OEM replacement air intake duct assembly for the MasterTemp 125 heater. This kit provides the complete direct air intake ducting required when the MasterTemp 125 is installed in a confined or semi-confined space that requires ducted combustion air from outside the equipment enclosure.
⚠️ IMPORTANT: KIT LISTING — MULTIPLE COMPONENTS INCLUDED
This listing is a kit, not a single individual component. All pieces required for the direct air intake duct assembly are included in this kit.
⚠️ 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.
The direct air intake duct kit routes fresh combustion air to the MasterTemp 125 burner assembly from an exterior or unconfined air source. Proper combustion air supply is critical to safe heater operation and efficient burner performance. This kit is specifically sized and configured for the MasterTemp 125 — it is not interchangeable with duct kits for other MasterTemp models.

Pro Tip
This duct kit is designed exclusively for the MasterTemp 125. Before ordering, confirm your heater's model number on the rating label located on the heater cabinet. If your installation requires a direct vent configuration (both intake and exhaust ducted), consult the MasterTemp 125 installation manual to confirm whether both a direct air intake kit and a separate exhaust vent kit are required for your specific installation type. All duct connections must be made by a licensed pool professional or qualified HVAC technician.
