The Grand Canyon 620-403 24V Transformer is the OEM foot-mount, hardwire transformer used to power Grand Canyon electronic ignition and EIS control boxes. It steps line voltage down to 24V AC, supplying the low-voltage power needed for compatible control modules, valves, and ignition components in Grand Canyon gas log and fire pit systems.
Designed as a direct replacement part, this 24V transformer features a foot-mount housing for secure installation and hardwire leads for permanent connection. When installed according to the EIS or control system manual and local code, it restores reliable low-voltage power to Grand Canyon’s electronic ignition (EIS) and millivolt control assemblies, helping keep your system operating safely and consistently.
