Macurco 70-2900-0021-1 Combustible Gas Detector

Product Description

The MACURCO 70-2900-0021-1 is a fixed-point combustible gas detector designed to monitor ambient air for the presence of flammable gases in residential and commercial environments. The unit operates as a standalone detection device and is intended for permanent installation in areas where combustible gas accumulation poses a safety risk. Licensed HVAC technicians, mechanical contractors, and fire-life-safety professionals typically specify and install this detector as part of a compliant gas detection system. The gray housing indicates a non-carbon-monoxide detection classification, targeting combustible gas sources such as natural gas and propane.

This detector is suited for installation in mechanical rooms, utility spaces, commercial kitchens, and other occupancies where combustible gas monitoring is required by code or insurance standards. It is sold as a single unit and is appropriate for both new construction and retrofit applications where a fixed-point sensor is needed to satisfy local mechanical or fire codes. The GD-12 designation identifies the product family within the MACURCO gas detection line.

Installation Notes

Installation should be performed by a licensed HVAC technician or fire-life-safety contractor familiar with local mechanical and fire codes. Shut off all gas supplies and de-energize the circuit before beginning wiring work. Sensor placement height should follow the manufacturer product manual requirements, as optimal mounting location varies based on the target gas density relative to air. Consult applicable local codes and the MACURCO GD-12 product manual for wiring, alarm output connections, and commissioning procedures.
