Modine Greenhouse Heater

Dayton, TX(Zone 9a)

We just recently purchased a used Modine heater for our greenhouse. The heater is set up for propane service and we are wanting to convert to natural gas. Can someone direct me to an outlet for Modine heater natural gas orfices? Thanks.

This place may be of some help.

I would also call your gas company...their service people may have the orifices in stock already.

and obviously make 100% certain everything is switched over...
I've known of too many places being burned down because the volume and pressure requirements for natgas vs propane are MUCH different.

Yes, what a shame, too.

Not sure what size Modine heater you have but there could easily be 7 burner tubes (each w/it's own jet/orifice) if it's of good size btu.

"Switching everything over" most likely will apply to the regulator(s) as well, is that what you mean, dp?

depending on the model, regulators valves, pilots and burners, i'm just saying it never hurts to have the gas company come inspect it all when it's complete.

I'm fairly ignorant on nat gas.... i've got a few reznors, a few modines and i keep buying these LB Whites :-) all for propane
course, we don't even have access to natural gas locally...

Appreciate your responses. Did not find what we were looking for at the link above, will call to see if they have an inventory that is not displayed on their web page.

The heater is a Modine Mod. PD 200

These folks have some Modine's...

Maybe email them and see if they have parts?

(I'd still suggest a pro gas service man check your stuff out though.)
