Gazco SKU: G6R-R4AUT Mertik Maxitrol Dual Thermocouple Gas Fire Receiver

The Mertik Maxitrol G6R-R4AUT is a specialized radio frequency (RF) receiver unit designed for gas fires and fireplaces. It is primarily used with GV60 gas control valves in systems that feature a second thermocouple or a dual-burner setup. 

Key Specifications & Features
Dual Thermocouple Support: Specifically designed for fireplaces with two burners or two thermocouple connections.
Power Supply: Operates on 4 x 1.5V AA alkaline batteries or a compatible AC mains adapter.
Compatibility: Commonly used in brands like Gazco, Dru, Faber, Bell Fires, and Nu-Flame.

It is not a direct replacement for the older G6R-R4A model (pre-2010), as the RF communication frequencies are different.

Safety Features: Includes low-battery audible alerts (frequent beeps when the motor turns) and an automatic backup system that switches to battery power if mains electricity fails.

A definitive list of specific GAZCO, Trimline, or DRU gas fire models that use the GR6-R4AUT receiver is not available.

This receiver is a component of the Mertik Maxitrol control system. The "T" in the model number indicates that this version is likely intended for appliances fitted with a second thermocouple for enhanced safety monitoring [citation:1]. It is generally found in electronic gas fire models manufactured after 2010 that feature remote control functionality [citation:2].

To determine if this is the correct part for a specific appliance, checking the following sources is generally recommended:

• Check the Appliance Data Badge: The rating plate on the gas fire usually lists the specific control system or receiver part number.

• Consult the Installation Manual: The technical or spare parts section of the manual typically states the exact receiver compatible with that model.

• Contact the Manufacturer or a Specialist Dealer: Reaching out directly to GAZCO, DRU, Trimline, or an authorized spare parts supplier with the appliance's serial number is often the most reliable way to confirm compatibility.

It is important to verify compatibility before purchasing, as using an incorrect receiver may affect the safety or functionality of the appliance [citation:1]
