  • Compatible with low-profile unit heaters sizes 30 to 75

Dayton 5ZJU1 Venting Kit

This venting kit is designed for low-profile gas-fired propeller unit heaters in the 30 to 75 size range. It provides a complete concentric intake and exhaust solution for commercial or industrial heating installations. The kit includes all components needed for a code-compliant horizontal or vertical vent run.

Upgrades from field-assembled venting

The kit replaces improvised pipe assemblies that require separate sourcing of collars, caps, gaskets and sealant. The jump is worth it when an ETL-listed, manufacturer-matched system is required for inspection or warranty compliance on compatible heaters. It eliminates the guesswork of matching diameters and sealing joints with generic parts.

Surface-mount installation with included hardware

Mounting is performed directly to the building exterior using the supplied vent box, inlet collar, gasket and sealant. The four-inch round opening fits the heater's factory flue without adapters. The most common issue is insufficient clearance for the wind deflector or misalignment of the concentric Y vent when the wall thickness varies from the assumed range.
