If you are using the IR stove that Mr Li sells you should be able to get going without any help once everything is connected.
Turn the pressure in the regulator all the way down, open the valves and slowy crank up the pressure regulator until you see 5KPa on the pressure gauge on the stove.

Cheers! Thanks @Marcelnl. It'll be good just to get going! Excited for this.

Once you have the power to feed the beast, don't be shy letting it rip early on. It took me a good while before discovering that I needed far more power than the 3Kpa my initial regulator did provide, true enough I'm using a perforated drum so YMMV.

Are you talking about the green regulator that normally comes with the Huky? How do you adjust it?

nope, I am referring to the new regulator needed to connect a UK propane bottle to the Huky, a variable regulator has a knob that allows the pressure to be adjusted to need. My Huky came with a non adjustable regulator.

Hi all -

I want to post an update as I'm continuing to work with a local gas engineering solutions company. The solution is getting more and more bespoke as we go! I'm going down the engineering rabbit hole that I never expected :lol: But it's all lending itself to creating an efficient operating pressure that is also safe. The proposed solution now includes:
  • (1) 50-150mbar regulator, POL inlet x1/4" female outlet
  • (2) 1/4" hex nipple malleable iron
  • (3) 1/2" x 1/4" reducing stock malleable iron
  • (4) 1/2" male x female ball valve with pressure test point
  • (5) hose/copper pipe connection (8-15mm options)
The point of this exercise is to achieve the optimal operating pressure that is 'fixed' and creates a safe solution.

As at least one of those components may need to be inserted directly on the Huky, I've asked the engineering firm to explore options for (1) adding a shut-off valve in case of emergencies so I then don't need to (a) exit the garage, (b) run into the back garden and around the greenhouse in order to (c) shut off the gas at the bottle. They'll also be assessing the current gauge to ensure it's sufficient and we may even look at the needle valve to see if options exist for a precision valve.

All in all - it's good. I'll continue to update the community on my progress so you know the solution I come to. Then, hopefully, anyone else living in the UK who's looking to purchase a Huky will know of a gas regulator option straight away :D
