About This Item
The Pentair Air Intake Kit (475002) is the OEM direct air intake duct kit for the Sta-Rite Max-E-Therm pool and spa heater series, enabling installation in applications where outside combustion air must be ducted directly to the heater.
IMPORTANT: COMPLETE KIT — MULTIPLE COMPONENTS INCLUDED
This listing is for the complete Air Intake Kit (one kit), which includes a service panel with cut-out, air orifice adapter, short 3" PVC pipe, 3" PVC union, and a screened termination cap. All components ship together as a single kit.
IMPORTANT: MODEL COMPATIBILITY — NOT FOR ALL HEATERS
This kit fits Max-E-Therm models 175, 200, 250, 300, 333, and 400. It is not compatible with the MasterTemp 125,000 BTU heater (model 461061). Verify your heater model number before ordering.
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 provides a factory-matched solution for routing outside combustion air directly to the Max-E-Therm heater. When the heater is installed in an enclosed equipment room or other location where indoor combustion air supply is restricted, this duct assembly channels fresh air from an exterior termination point to the heater's air intake. The screened termination cap prevents debris and pest entry at the exterior opening.

Poolaroo Pro Tip
This kit is listed as an optional accessory — it is required only when the installation calls for direct outside air intake ducting. Before ordering, confirm your Max-E-Therm installation requires this configuration; consult your heater's installation manual for combustion air requirements specific to your equipment room setup. Gas heater components must be installed by a licensed pool professional or qualified HVAC technician.
