Worked as expected though there is a rattle inside module
The challenge was determining how to access the existing igniter module. It turns out all you have to do is pop off the cover plate which holds the igniter module. With this knowledge, it is a 5-minute fix.
Without this knowledge, it is much much longer!

works fine
All I needed was the top part but had to order the whole thing and it came by snail mail.

Looked as if I needed to dismantle entire unit to get to ignitor but after getting half of it apart I saw I only needed to "pop out" the the panel and the rest was easy.

The original ignitor module screw-on cap was defective - would not produce a spark to light the pilot.

Parts Used
(1) Unscrewed the old cap off the original ignitor module.
(2) Unscrewed the new cap off the new ignitor module.
(3) Screwed the new cap onto the original ignitor module.
(4) Pushed down the new cap to light the pilot.
The only problem with the original ignitor module was a defective cap. It simply wore out from being pushed down so many times. It would be nice if eReplacementParts.com would sell only the cap. I am sure that the ignitor module body seldom goes bad on these heaters. So I spent $12 + shipping just to get the cap and will probably end up throwing the new ignitor module body away. It is not worth tearing down half the heater to replace it. Should have cost me $4 at the most for a cap!!

1. Removed the heater from the case.
2. Disconnected the gas line.
3. Dismounted the pressure regulator from the bracket.
4. Installed the new pressure regulator on the bracket.
5. Reconnected and torqued the gas line b-nut and reinstalled the heater core in protective case.
6. Leak and operational checks were good. Piece of cake when you have access to the right parts and time. Very pleased with efficiency and the parts availability at eReplacementParts.com.
