I have a Grimm Arch with raised flue pans. I'm beginning to consider changing to oil for next year. What has to be done to convert a wood fired arch to oil? Can a plate just be attached to the front after removing the doors with the oil gun attached? Does the an extension need to be added to get the gun out farther so the heat can be gotten under the first part of the syrup pan? For an 3x8 what oil gun is needed and how big should the nozzle be? What type of nozzle?
Any info appreciated.
If I go with it, I also want an insulated cover to help block out some of the noise, Ideas please.

Dave. Sounds like you're searching for ways to really cut down on sugarhouse time. What's up? Is it starting to wear you down?

I can't answer your questions but I don't think you'll regret the switch. Also have you considered selling the arch and starting fresh? That may not be an option,but if it is its a good one.

It can be done I've heard of some guys doing it. A hood to quiet it down is a must mine very loud with the hood off. Plus as you said extending the front would probably help get the fire where you want it. I think I leader has some PDFs that have been shared on here before about recommendations for oil fired arches.
Might be worth checking out this link.

Here is Leader's info.

Nice chart on sizes.
I would call these starting points. I built my own oil arch. I had to try different nozzles/ pressures to get front pan to boil all the way to the front. Ended up with 80H nozzles. It works but still does not boil the way I want. I think I am going to move the burner underneath the back pan to reverse fire it. I have a 701 on my 3x12. With 2-6 gph nozzles. Pressure about 125. Stack temp 670. You should also realize that nozzles are gph rated at 100 psi. So if your burner does not have a gauge on it you do not know how much oil you are burning. I have a plastic barrel over my burner to lower noise. Make sure to leave enough space around an enclosure for combustion air. I did not at first and stack temp would drop with cover on burner.
