How to fix a Master Space Heater

Kallstrom Sweet Corn here , I think I may have a fuel problem . My heater is 34 hears old [ we bought new ] has not been used in approx. 15 years , has some rust in tank . [ how did you get rid of rust in tank ?

If I am not getting fuel what then I cleaned nozzle go nothing I took fuel line off nozzle manifold start nothing coming out of fuel line

Is this setup the same on the 140's? Mine is doing the same but I found both fuel hoses were bad. I replaced them and still doing the same.

Everything you did was wrong. If you pulled the air line then it wouldn't pull fuel so you could have left the igniter wire connected. If that grounded out you ran a change of frying the high voltage ignition. Air pump pressure needs to be checked from the rear test port with the line connected to the nozzle. Never saw anyone ever use PB blaster as a cleaner?

I wish I found this before I started replacing parts, thank you for the video. Was very helpful. Cleaning my nozzle did the trick!

Thank you for all the help!

What if it's not firing

Not sure if this would help anybody but you can repalce the injector nozzle which comes with a new filter already attached.....17mm spanner and its off. Loosen the deflector plate to give yourself a little more room to get your spanner on the nozzle head, and once removed you will see the filter. This is a common issue with these heaters, often over looked.

Thanks!

Hello my heater similar to yours stays on for about 10 seconds then shuts off I have to reset it in the back for it to turn on then does the same 10 sec later

I have a Master 135K BTU unit that came with the farm I bought. The unit turns on and heats but it sputters a lot. It has a gage on it and reads 5.5 psig, which it is what the plate says it should be. The fuel is probably old so I realize that. But is there something else I need to check?

Thank you for this simple, easy to follow guide. I printed out the manual for my ProTemp PT-70T-KFA (70,000btu) heater and was going to 'logic my way' through it to figure out what was wrong but your guide put me on the scent of what was wrong from the get go. Previous owner had apparently put bad fuel, or old diesel, into it and yep - cleaning out the jet led me to find several chunky bits of 'fuel'.

While I was in there I installed a spare fuel filter & zip-tied it away from heat & the fan.... hit the switch & she fired right up!

Many thanks!

Hi Ron
You video has come in great as mine was doing the same cleaned it out and it's firing lighting and going outside think the pressure is wrong butni don't have guage . Mine says 2.5 psi is there anyway you could tell me how many turns from all the way in it might be please, I'm in the UK and delivery of a guage is 7 days to me

I have a two burner space heater in my bed room .it has worked fine for years.this morning the pilot lite want stay on

Ii need to know how to keep my reddy heater pilot light lit?

You will get a more accurate reading by testing the pressure at the test point, blocking the pipe like you did only tells you the max pressure the pump can supply, you need the air flowing through the system and out the nozzle to set the correct pressure.
I had a similar problem with my own B70 model and after too many hours spent cleaning, testing and adjusting everything more then once, it turned out to be a hairline crack in the plastic cover where the pressure adjustment screw is located, when the screws were tightened the crack got wider and it lost all the air pressure, i super glued it and is now working perfect

What kind of gauge are you using ?

I have a master 80,000 BTU and when I plug it in the green light comes on but the fan doesnt start. Think the thermostat is busted or what could be the issue?

Ron I have a master 115,000 btu heater. I'm have a issue, with the top cover off it runs perfect, as soon as I put the top cover on it dies. Any suggestions?

Can you use brake cleaner? To clean it

Just curious, why do you continuously plug and unplug the unit instead of using the on-off switch?

Thenks for this film. Thanks to you i repair my machine. 👍👍
