Confirm the appliance requirements

Match the complete existing module number, supply rating, flame-sensing arrangement, gas-valve load, timing and terminal layout against the appliance service instructions. Similar-looking modules may use different sequences. An 11-second timer alone does not establish compatibility. Installation and commissioning should be completed by a qualified technician.
