Switching from propane to gas

I'm wondering if anyone can tell me if these items can be switched from propane orifices to gas:

Trane XL80 furnace
Rheem Fury Hot water heater model 41v50-36PF

Cooktop: 30" model # 790.32099402 Serial # NF 82020358

I just had a gas line dug and now I'm being told the orifices cannot be switched and I'm stressing because I can't afford to replace them!!!!

Thank you!!

You should generally be able to convert from propane to natural gas. For example, your Rheem hot water heater was natural gas from the factory and a conversion kit was undoubtedly used to go LP. I think the same applies to the Trane.

But, don't let me or anyone else tell you with assurance about them all. My suggestion is to contact the service / help line for each product and find out specifics (including making certain the product is certified for natural gas) then get a pro to handle it. Your gas company may be able to recommend someone.

Thanks. I'll make some calls.

I forgot to put "Kenmore" in. Sorry about that.

I install a lot of cooktops, your cooktop is convertible as most are.

Are you saying the NG orifices are no longer available?

Here's a view of your cooktop instructions:

You will need to order new orifices.

And was manufactured by Frigidaire.

Honestly I bought this cooktop and I wonder if the gas orifice is on it. How can I tell? I bought it second hand but not used.

I called a Rheem installer as directed on their website. They said they would call me back in a COUPLE OF DAYS!!! I also emailed the manufacturer directly two weeks ago and haven't had any response. Doesn't it appear from this label on the tank that it's only for LP?

I assume there is no pouch attached to the regulator with the propane orifices and instructions.
If that package is missing, that's a good sign the top was already converted to LPG.

To verify you have the correct NG orifices already installed will be difficult. The conversion instructions include a chart identifying the different orifices and where they go.
That chart and a magnifying glass is needed. The installation manual doesn't identify orifices.

I would order new NG orifices, plus a conversion kit to LPG.
The conversion kit will let you identify the orifices and change them if needed.

To the best of my knowledge water heaters are NOT field convertible between propane and natural gas. This has been true for at least ten years, possibly a lot (not alot) longer.

That's what one person told me but then a few people said it could be. If only the manufacturer would respond. Thanks

I've converted many water heaters.. Drilled the orifices and installed a regulator.
