Re: Which pressure gauge to use?

For permanent, you want "inches of water" gauge (maybe 0 to 3"). But this is also easily done with just a "U" of clear tubing with water in it for testing purposes.

Re: Fire to crown sheet distance

No disagreement with what you say (been there done that with GE / WESTINGHOUSE, and yes even Zink), but flame on our boilers doesn't realistically hurt...cannot say that I have ever seen a steel (or copper) model boiler that failed as a result of this type of impingement...and cannot say the delam ...

Re: propane question

.... Propane forklifts for example circulate engine coolant through the regulator to keep it from icing up. Forklifts (and generators, etc.) heat a device called a 'vaporizer' not the tank. This is because they require large amounts of gas. Liquid is fed to the vaporizer, heated to convert it to a ...

Re: propane question

I suspect that even two of those tanks operating simultaneously will have icing problems .... That might be avoided if heat is provided to keep the bottles from icing. If by this you mean 'heat' above ambient temp - It is never advisable to heat a propane tank! Inattention/malfunction can lead to c...

Re: propane question

Re: Those valves I listed, when I’m installing the tanks onto the manifold, will gas flow out the other valve (assuming I don’t have shut offs)? I assume yes, because it does not mention a check valve and normally, a grill/whatever that uses these would not need it to have a check valve (i.e.: they...

Also ...

Be sure to use a regulator designed for fuel gas - not an air regulator. The reason is that an air regulator has a vent which is bad near open flame!

Re: propane question

As John said, the two cylinders will equalize and equal amounts of gas will be drawn (assuming the tanks are at the same temperature). Note: a) I would add a shutoff on each bottle. That way you can swap bottles without killing the fire/pilot (assuming the other bottle has a bit of propane in it). T...

based on the 1" scale video that Dave forwarded me https://www.youtube.com/watch?v=MO8u6_8xsq4 .... Dave Yup, I have seen that style in the past but had forgotten about it. It does work well.

Kick-Switches

I want to build some kick-switches. I need a mechanism that is simple (not a lot of parts) and is free-moving.

Do you have a favorite kick-switch design?
