Description
The Field Controls 46092800 Vent Hood (Model SWH‑4) is a rugged, 4‑inch aluminum vent hood designed for use with PVG, PVO, and other power venters as well as forced draft systems. Built to stand up under harsh conditions, this vent hood maintains safe, efficient exhaust venting for gas, LP gas, or oil‑fired equipment.
Features:
- The concentric pipe, angled outlet deflectors, and spaced plate design allow for better heat dissipation
- This type of construction minimizes the effects of heat on the outside wall
- The angled hood design reduces the effects of wind on the venting system
- The inner and outer pipe are a continuous structure
- This allows for easy installation to power venter or vent pipe and also eliminates possible positive pressure leaks in the wall section
- Field vent hoods meet the highest standards for safety and reliability, built in accordance with guidelines from NFPA211, NFPA54 and ANSIZ21.47
- SWH-4 has a 7-5/8 x7-5/8 in shield for zero clearance to combustibles
