Pellethead Vacuum Pressure Switch for Harman Heatilator Boilers 20168

Description

Product Overview

The Pellethead vacuum pressure switch is engineered for precise pressure monitoring in pellet boiler exhaust chambers and vent piping. Constructed from high‑temperature resistant materials, it reliably detects pressure spikes caused by blocked exhaust pathways. The compact unit measures 4.69 x 3.86 x 2.44 inches and weighs only 2.4 ounces, making installation straightforward. Model 20168 has been a top‑ranked pressure switch in the Industrial & Scientific category since its release in August 2020, earning a 4.4‑star rating from 33 verified customers.

Usage

Designed for Harman and Heatilator pellet boiler lines, this switch fits models such as Absolute 43, Accentra 52I, HydroFlex 60, BA100, BH105, and more. It is ideal for residential heating, small‑business installations, and larger industrial setups where continuous operation demands safety redundancy. The sensor activates when exhaust pressure reaches a preset threshold, cutting power to the auger feed motor to prevent fuel overflow and firebox damage. Technicians appreciate its plug‑and‑play wiring and clear pressure‑set points.
