Bonjour Nick,
Beautiful and perfectly running smoothly steam machine.
Besides this, you have a very efficient safety valve, not so common believe me because most of mines leak after the first pop  :(

I’m a little late to the party but you wouldn’t want to use the original Stuart burner. The original burner is great for producing carbon monoxide and little else. That’s why I adapted the Bix burner.

Hi Nick,

I hope that you are happy with that SH4 because I miss it. It’s one of the few things that I regret selling.

Title: Stuart SH 4 Boiler
Post by: livesteamer on January 22, 2021, 08:24:28 pm

Can anyone tell me if the burner for a Stuart SH 4 boiler uses a gas nozzle? I acquired a Stuart 10V steam plant with an SH 4 boiler (discontinued) but it was missing the burner assembly. Stuart currently uses an HB 4 boiler with a 2" ceramic burner for its steam plants but it cannot be adapted to the SH 4. Stuart informed me that the SH 4 burner used a camper gas mix (butane/propane) that acted like a blowtorch, so I'm assuming a gas jet nozzle created the torch.
