What it is

The Ideal 176777 is a gas valve kit rated for 120kW appliances, produced by Ideal for its commercial boiler range. It controls the flow of gas to the burner, allowing the appliance to modulate output and hold a stable flame through the firing cycle. The kit is used on Evomax 120 and Instinct Heat 120 commercial units.

  • Fault codes relating to flame detection or gas supply appear on the controls
