The genuine OEM Lennox Y5358 gas valve kit is built specifically for the DKVLT-200 wall-mounted condensing gas boiler. This gas valve meters and modulates fuel delivery to the burner, adjusting output to meet heating load while ensuring clean, efficient combustion. It is a key safety component that coordinates with the ignition system and control board to provide dependable, on-demand heat across the boiler's full firing range.

Common signs of a failing gas valve include no ignition, short-cycling, fluctuating supply water temperatures, delayed or rough ignition, and total loss of heat. A malfunctioning valve frequently produces ignition-lockout fault codes when the control detects incorrect gas flow. Any of these conditions should be addressed quickly to keep the system operating safely.

Installing an OEM Lennox Y5358 valve guarantees a precise factory fit, proper pressure calibration, and complete compatibility with the DKVLT-200's control sequence. Non-OEM alternatives risk incorrect flow rates, combustion issues, and shortened service life. This factory kit preserves your boiler's rated efficiency and warranty protection.
