Introduction

This kit contains the materials necessary to convert a DHW series 

hood to a recirculating configuration in instances where exhausting 

the hood outside the building is not practical or desired. The kit 

consists of a top cap and charcoal filter(s). When installed, the top 

cap redirects air flow out the vents in the sides of the hood chimney 

assembly. The provided charcoal filter(s) are installed underneath 

the baffle type filters included with the hood. The charcoal filter(s)
