How do you replace insulation ? It was destroyed by mice. Heater runs so hot top wires melted!

There is very little insulation on top, and to what you may consider as insulation...
the small amount of insulation is used between the header, combustion chamber/box and any wires: thermostat and limit.
if you are referring to wires at top in the front of heater, behind removable front door... Then that is due to (can be considered as insulation as well - as that is what it's supposed to do: Keep the heat in the combustion chamber/box) broken fire tile/brick!
this is common and needs to be replaced.
Call a local service provider , or remove the top assembly to access the Heat Exchanger, disconnect plumbing, then remove the H.E.
You can now see the fire brick, ANY cracks or sacrificed integrity of that brick, need replacement. The heat travels Right THRU that crack!
An easier way to visually inspect brick, would be to disconnect gas line from heater, then remove burner tray. Many wrong installations, Actually NOT To Code, will have a union for the line INSIDE the heater, close to the gas valve. Although this is not to code, it makes for a very simple burner tray removal. Anyway, once burner tray removal is complete, use a mirror and flashlight, and you can inspect brick from bottom.
Link below what that brick kit looks like...

Good Luck

The brick does not glow red you see the flame all the time, goes up pass the brick. Is this repairable or dangerous? (Dyna glo gas wall heater -model RMI-70LP)

Both repairable and dangerous. The burner need blown out with a air compressor. This should take care of it. The unit not glowing red will create CO. Which will make you sick or even can kill you.

I have a Empire Corcho radiant nature gas space heater that the middle brick panel flairs when on. When the other two bricks light they burn normal (ie no flair or flames except slight flame as bricks heat...

Problem sounds like the incoming gas pressure is too high or the burner below the middle brick has debris or trash clogging some of the openings. Recommended next step is to remove all power / natural gas to the space heater and check all burners for debris or blockage. If burners are clear have your natural gas provider test the incoming gas pressure to ensure it is correct for that appliance.

the first thing I would do is pull it apart and give the bricks a good cleaning with a wire brush to get any soot off. If they are broken beyond the point of replaceing them in the unit you will need new bricks.

Glo Warm propane heater started to go out. I blew out the pilot with air compressor. It is staying on, but the middle burner in back of the pilot light is flaming a little above the brick. The other...

sounds like when you blew heater out with air compressor you moved brick so flame isn't hitting bottom of brick like they should. You should try and put brick back on top of flame so that you don't get to much heat on the refractory of the heater.The refractory will take the heat for awhile then refractory will start to break down. Then you will either have to install new refractory or replace heater
