Ruud AS36352-2H 3" Draft Hood Vent Fitting for Gas Water Heaters

Ruud AS36352-2H 3" Draft Hood Vent Fitting for Gas Water Heaters

The Ruud AS36352-2H is a 3" draft hood designed as a replacement venting component for gas-fired water heating equipment. A draft hood is installed at the flue outlet of a gas appliance, where it relieves excess draft and allows dilution air to mix with combustion by-products before they enter the vent connector and chimney or vent pipe. This 3" trade size unit is sized to match the flue outlet and vent connector on compatible Ruud gas water heater models, and it is intended for use as a like-for-like replacement part during service, repair, or rough-in installation work performed by a licensed plumbing or HVAC technician. Because the draft hood sits directly on top of the appliance jacket ahead of the vent connector, it is a functional mechanical component rather than a visible finished fixture, and correct sizing at this connection point is important for maintaining proper draft and dilution air flow at the appliance.

Key Features

• Trade Size: 3" flue/vent connection, sized to mate with the flue outlet on compatible gas-fired water heater models.
• Draft Hood Function: Relieves excess updraft and allows dilution air to enter the venting system ahead of the vent connector, helping maintain proper draft at the appliance flue outlet.
• Direct-Fit Replacement: Manufactured by Ruud as a service replacement part for use on compatible gas water heater models, model AS36352-2H.
• Rough-In / Service Component: Installed at the top of the appliance jacket ahead of the vent connector, this is a behind-the-appliance mechanical part rather than a finished, visible fixture.
• OEM Sizing: Matches the original flue connection dimensions on compatible equipment, helping technicians avoid guesswork when re-venting or servicing a unit.
