Description

Product Overview

The Holdly Flammable Vapor Sensor (Model HMP6, Part Number 25VS) is a critical safety component designed for gas water heaters. This white sensor measures 1x1x1 inches and weighs just 0.352 ounces, featuring advanced film technology that rapidly reacts to gasoline vapors in the surrounding air. The complete kit includes the flammable vapor sensor, a cap plug, and a wire tie for secure installation. Manufactured by Holdly with part number 25VS, this sensor operates without requiring batteries or external power, drawing minimal energy from the water heater’s control circuit to monitor vapor concentrations and trigger safety protocols when needed.

Usage

This flammable vapor sensor is specifically designed for residential and commercial gas water heater systems, particularly those equipped with FVIR (Flammable Vapor Ignition Resistance) technology. It’s ideal for homeowners, property managers, and professional technicians maintaining Rheem, Ruud, Richmond, AO Smith, and Bradford White water heater models. The sensor activates in environments where gasoline vapors might accumulate near water heater installations, such as garages, utility rooms, or basements where fuel-powered equipment is stored. When vapor concentrations reach potentially dangerous levels, the sensor initiates an immediate safety response to prevent ignition risks.
