⚠️ DISCONTINUED MODEL – COMPATIBILITY NOTICE

The Mertik Maxitrol G6R-R4A (Generation 1) receiver has been permanently discontinued and is no longer produced.

Important: Generation 1 receivers operate on an older communication protocol and are not compatible with current Generation 2 handsets (e.g. G6R-H4T2). Replacing only the receiver is not possible; you must replace both the remote handset and the receiver as a set.

Recommended Replacement Options:

  • Option 1 (Standard Upgrade): Upgrade to the current G6R Generation 2 Set (Receiver G6R-R4AUC + Handset G6R-H4T2).
  • Option 2 (Modern Upgrade): Complete migration to the SYMAX 2 (B6R) 868 MHz system (Receiver B6R-R8PC + Handset B6R-H8TV4PBD) for enhanced range and display options.

Description

Mertik Maxitrol G6R-R4A Gas Fire Receiver (Gen 1) – Replacement Guide

The Mertik Maxitrol G6R-R4A is a first-generation electronic receiver unit widely installed in premium balanced flue and open flue gas fires from leading manufacturers, including Dru, Faber, Bellfires, Wanders, Element4, and Valor .

Because this original Generation 1 series (operating on 433.92 MHz with early firmware) has been phased out by the manufacturer, replacement units are no longer manufactured.

 

Why Can’t You Replace Only the Receiver?

Mertik Maxitrol gas control systems require matched pairing between the handheld transmitter (remote control) and the electronic receiver box.

Generation 1 transmitters (such as the early G6R-H4T1) cannot pair with Generation 2 receivers (G6R-R4AU, G6R-R4AUT, or G6R-R4AUC).

Attempting to swap only the receiver will result in an unresponsive gas valve, error beeps, or an inability to complete the ignition cycle.

If your existing G6R-R4A receiver is defective, suffering from battery corrosion, or failing to ignite the pilot flame, you must replace the electronic set together.
