Ignition kit for natural-gas fireplaces

This VEVOR pilot assembly is a direct replacement kit for natural-gas fireplaces. It includes a pilot tube, igniter wire, thermocouple and thermopile, each measuring 24 in. The unit weighs 0.46 lbs and measures 6.30 x 4.72 x 1.57 in. It suits owners of compatible Quadra-Fire, Heat & Glo or Heatilator models needing a new ignition source.

Replaces OEM parts 485-510A, 4021-736, 2103-010

The assembly replaces original equipment numbers 485-510A, 4021-736 and 2103-010. The jump is worth it when the existing pilot fails to hold a flame or the gas valve will not stay open. It is not for propane appliances or fireplaces that use a different pilot bracket design.

Straightforward bracket-mounted install

Installation consists of removing the old pilot bracket and securing the new assembly with the supplied hardware. The colour-coded wires connect to the existing gas valve terminals. What usually goes wrong is routing the 24 in tubes too tightly, which kinks the pilot tube, or overtightening the thermocouple nut and stripping the valve threads.

Questions about this item

What are the dimensions of the ZH-1003A pilot assembly for mounting clearance?

The assembly measures 6.30 x 4.72 x 1.57 inches (160 x 120 x 40 mm) and weighs 0.46 lbs (0.21 kg).

How do I install this pilot assembly and what is the common mistake?

Replace the old unit by connecting the 24-inch pilot tube, igniter wire, thermocouple, and thermopile; the step often missed is ensuring the bracket is securely fastened so the thermocouple sits correctly in the flame path.

Which components of this kit typically need replacement over time?

The thermocouple and thermopile are the wear items; they degrade with heat cycles and should be checked if the pilot flame fails to hold or the main burner will not stay lit.
