Is it possible to convert a Universal Model 3500-FACNG construction heater from natural gas to propane?

glo-warm doesnt sell a conversion kit since they have propane version they sell the propane unit --their are universal conversion kits but you would need to check if their compatible to the glo warm unit

It is possible to convert a natural gas ventless wall heater to propane, but it is not recommended. This type of conversion requires a significant amount of technical knowledge and expertise, and it is best to leave it to a professional. Additionally, the Charmglow Blue Flame CGN200TB model is not designed to be converted to propane, so even if you have the technical know-how, it may not be possible. It is important to check with the manufacturer and/or a professional before attempting any conversion.

With knowledge of make and model, your manufacturer can supply a retailer who can provide you with proper kit...

Some water heaters allows changeover by installing new chipboard or changing dip switches... some do not.
Propane burns much hotter with higher pressure than natural gas

It should be. You should be able to replace the oriface and the regulator. Propane is at a higher pressure than natural gas.

Sorry to read about your problem, I hope this helps you out.

Only the portable heaters that are manufactured to be used on dual fuel (nat gas/propane) can switch from one to another. If they are made for 1 type of gas only, they are not field serviceable and cannot be converted. Douglas

Yes, there are kits out for that but you will want to get a professional to do the conversion....he will have the proper tools and equipment to set it up so that it works safely for you...

I'm sure you can, contact the manufacturer and ask if they have a natural gas jet or orfice for your model heater, these are usually very easy to replace.

Yes it is possible and a good idea. You need to have a regulator installed to reduce the pressure to the heater and this is a simple procedure. Contact your local Propane distributor and they will probably do this free to get your business.
