Pilot light keeps blowing out. When I do get it working it only works for a little while and the pilot light goes out again. It seems like there is to much presure. I have regular 5 gal propane bottle...

dmartin - Unless there is a strong draft, pilots don't normally don't blow out.

What you described, sounds more like the interior of the heater needs a thorough cleaning. Especially, the pilot assembly and the Oxygen Depletion Sensor (ODS), which is part of the pilot. Also, the placement of the gas grill tank you're using to fuel the heater, may also being playing a role in it, too.
How far away is the tank from the heater and what size gas line is running from the tank to the heater and was it professionally installed? If you live in a high altitude are (above 2000 feet) this may also, be causing the problem.

I have included a link, which demonstrates the proper way to clean a pilot assembly and the ODS sensor. This should be a big help to you.

Please let me know about my questions above and I can provide you with more information on further troubleshooting the problem.

I have a mr heater 75000 with a 4 flash blink code. the heater is brand new, only worked for 3 days. i have bypassed the 2 switches but still cant clear the 4 flash blink code.

According to the Owners/Installation Manual, the 4 flash blink code indicates that the High Limit or Roll Out Switch is open. This may be caused by a venting problem or high altitude operation. make sure you have the proper pressure to the heater's regulator. For Natural Gas it must be a continuous 7 water column inches.

For further information, I have included a link to your Owners Manual that you can download and print, for future reference.

Hope this helped to solve your problem.

I am looking for basic information regarding forced air space heaters. When the specs indicate "will heat xxxxx sq. Ft space, what does that actually mean? A "Space" is often measured in...

The basic method that i've used for years is using square feet of floor space. There are all sorts of multipliers in different calculations dependent on number of windows, type of insulation, numberof doors to exterior, area of the country you live in and number of people in your house.
We live in north central Kansas and it gets plenty cold and hot here. I figure 1 ton of cooling for each 500square feet of space and 40,000 B.T.U. s for heating. This is just a quick way to figure and around here it works pretty well.
I always thought it was better to err on the side of a little more is better then a liitle less.
Hope this helps you some. Thanks

Changing lp heater to use natural gas

Yes. the orifice has a tiny hole in it.It is located at the tip of the pilot before the flame, and at the tip of the injectors. Natural gas and propane molecules are different sizes in the vapor state. The orifice regulates how much vapor comes out. You need to change the orifice in the pilot and the burner injectors for it to work properly. If you don't you will get a very large flame or a very small one, depending which way convert from. If you have the papers from the company that made the heater, they should be able to help you changer over. You also may need to make some adjustment if you are at high altitude, 2,000' or more, as the air is thinner (less oxygen) so the regulator needs to be set to higher volume.

High Altitude Electric Heaters

I have never heard of altitude effecting the electric. Watts amps and volts are different than burning a gas, like propane. The high altitude has less oxygen thus requiring the combustion to be effected. If your wires are over heating when you use maximum wattage (amps) you need to install larger wire with the correct size breaker. Look up ohms law. Its a basic electrical formula and will help you get this right.
