About This Item
The Pentair Air Intake Kit (475971) is the OEM replacement air intake assembly for the Pentair ETi 400 High Efficiency Gas Heater, designed specifically for indoor installations where adequate combustion air supply cannot be guaranteed by the surrounding environment.
IMPORTANT: KIT LISTING — MULTIPLE COMPONENTS INCLUDED
This listing is for a complete Air Intake Kit, not a single component. All kit contents are intended to be installed together as a matched set.
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.
This kit supplies the ETi 400 heater with a dedicated combustion air intake path when the installation environment — such as a utility room, basement, or enclosed equipment space — cannot provide sufficient ambient air for proper burner operation. Without an adequate air supply, combustion efficiency drops and the heater may fail to operate safely or reliably.

Poolaroo Pro Tip
Before ordering, confirm your ETi 400 heater is installed in a location where outdoor combustion air cannot be drawn in passively — such as a sealed mechanical room or interior utility space. If the heater is installed outdoors or in a well-ventilated open area, this indoor air intake kit is not required. Consult your ETi 400 installation manual or a licensed pool technician to determine whether your installation qualifies as an indoor application under Pentair's guidelines.
