VEVOR Gas Pilot Assembly ZH-919A

This natural gas pilot assembly replaces OE part numbers 4021-732 and 25660 for Heatilator fireplaces. It is designed for homeowners and technicians who need a direct-fit ignition replacement. The unit operates on natural gas and includes a silver-coloured bracket for mounting.

Bundled pilot tube, thermopile.

The package supplies a 24 in pilot tube, a 24 in thermopile, a 22 in igniter wire and a 16 in thermocouple. Heat-resistant wiring and a sturdy bracket are integrated, providing corrosion-resistant connections. A user manual is also included to guide installation and flame monitoring setup.

Verify fireplace model and gas type before ordering

Confirm that your fireplace uses natural gas and accepts the listed OE part numbers. Check that the 6.30 x 4.72 x 1.57 in dimensions suit the existing mounting space. Builders needing a propane-compatible assembly or a different OE reference should look elsewhere.

Questions about this item

How often should the thermocouple and thermopile be inspected or replaced?

The assembly includes a 16 in thermocouple and 24 in thermopile; inspect them annually and replace if the pilot flame becomes unstable or the safety shut-off triggers unexpectedly.

Which component reaches its temperature limit first during continuous operation?

The thermocouple and thermopile are the primary heat sensors; sustained high flame temperatures will degrade these elements before the pilot tube or bracket shows wear.

How much heat does the pilot assembly add to the fireplace surround when running all day?

The compact bracket measures 6.30 x 4.72 x 1.57 in and weighs 0.42 lbs, so the pilot flame itself contributes minimal additional heat to the surrounding area.
