Description

Vent-free application. The Honeywell VS8421D1104 is a millivolt gas valve from the VS8421 series - Honeywell's vent-free counterpart to the vented VS8420. It is a compact self-powered control used on vent-free gas fireplaces, log sets, free-standing stoves and room space heaters.

The valve is self-generating: a thermopile heated by the standing pilot flame supplies the operating power, so no transformer or line voltage is required. The gas control knob offers ON, PILOT and OFF positions with a pilot adjustment screw.

The critical difference from the VS8420 is safety shutoff timing. Honeywell specifies that VS8421 pilot gas flow stops within thirty seconds of pilot flame loss, against three minutes on the vented VS8420. That fast shutoff is what makes the valve appropriate for vent-free appliances, where combustion products discharge into the living space and an oxygen depletion sensor must act quickly. A vented-service VS8420 is not a substitute.

Pipe size, regulator settings, gas type and BTU capacity are not published for dash number 1104 - please confirm against the label on your existing valve before ordering.
