ISO NG to Propane Conversion Kit Big Maxx Heater

[cdnbikerdude]

Hi All

I purchased a used Big Maxx 50K heater. Looking to see if someone has the NG to propane conversion kit they do not need. Usually a new store bought unit includes this.... and most don't need and toss in garbage.

If you happen to still have the orifices and spring I would like to purchase / trade with you.

Thank you
Michael

Let me see if I threw it out or not.

I just installed an 80K unit, I think I still have these parts in my trash pile yet to go out to the bin.

Not sure if they're compatible though...

Thanks Schoeny.... according the website they are the same (just more jets for the larger unit). My small 50K unit needs 3x jets. I think the 80K is 5 or 6 jets.

I may have them from my 50k heater,
Where are you located?

Hey AldeanFan... I'm in Woodstock, Ont. I can of course pay for shipping. Thank you

I've only got the orifices, not the spring, sorry.

Which gas valve is it? You should be able to get the spring kit from Amazon.

Older Mr Heater 45,000 convert LP to NG

Utility ran a natural gas line down my street this spring. I am excited to get hooked up but need to convert my LP appliances. In garage #2 I have a Mr Heater 45,000 (MHU45) with the older RobertShaw 2000DER valve. The Mr Heater part I need 60066 is no longer available. I can find the...
