I own a Comstock-Castle Range model C330-11.It has been converted to use propane. It has 4 burners @ 13,000 BTU ea and a griddle @ 20,000 BTU on the stove top. It has a single oven with no broiler @ 25,000 BTU. The stove is used in my residence in a remote location and I cannot get Authorized Service Tech or anyone else to come and service my range. I need a link to an Operations Manual specific to this stove so I can do it my self. The current problem is: A. pilot will not stay lit; and B. the oven goes off when cooking. I've been told to clean pilot assy. and replace the thermocouple. Need diagram and stepXstep proceedure. Thank you in advance for your help. Lee Pittard at [email protected]

Question edited for clarity and spelling of thermocouple.
Question moved from Heating and Cooling to maker category.

I can think of two reasons for this on a catering oven.

1. the burner has become blocked or has partially blocked jets increasing pressure to the ones closest to the pilot. Remove it and boil it in heavy duty cleaner and water and scrub it. Rinse well and replace.

1. Most thermocouples have a shroud to contain the flame and very often they will burn away, drop off or move. It holds the flame where it is supposed to be on the thermocouple.

I see if I can find a diagram, ensure you posted right model number here.

It has to do with the diameter of th holes. The holes for natural gas are much bigger and this sounds like could definitely be your problem.
Thanks,

Check for plugged orfices, usually grease build up cause these problems

Hi there.

Burner orifice size for propane gas is number 55. You have to replace all burner orifice with this size if you want to use the fryer with propane gas. Pilot burner orifice should be replaced with propane pilot orifice.The gas valve spring should also be replaced with propane spring kit. The difference between the two spring is the natural gas spring is lighter or thinner compare with the propane gas valve spring.

Regards.

The design pressure for Castle ranges on Natural gas is 4" W.C. (water column) Make sure you change or convert the pressure regulator in the rear and change the orifice tips on all gas valves

If it doesnt fit your specs. then i would suggest u find a thermador parts place and begin to buy the parts for the griddle as replacement parts. find a model of the stove set up that you want and make a list of all the parts that go to the griddle attachment.

My guess is that the reason for the flat "No" on the retrofit was that griddles require a thermostat similar to the one on the oven and broilers do not. So if their is no room behind the face plate where the knob would go then you can't put in a griddle. The other issue might be that the burners for the griddle wont line up with the brackets that are holding up all the broiler burners now. The griddle burner looks exactly like the one from the over only smaller so it has to line up strait where a regular front and back burner have to line up offset. maybe since you have the broiler already that should not be an issue? Then the problem is finding the griddle top it self that is going to be spendy. I think the link i gave at the top is your best bet. good luck.

Hello. Please advise if your unit is supposed to run on propane, at the bottom of the oven door is a smaller panel, depending on age, it either lifts slightly, and then folds down, or clearly has screws on the front. Your Model/rating plate is behind this, either on the back of the panel, a tag screwed to the frame, or on the bottom ledge of this area. It should state what gas the unit is meant for, propane or natural. If it was not converted to run on propane, or made to run on propane, this is your problem. If it was built/converted for propane I would suggest you contact your propane supplier, or a restaurant service company to look at it, it would require a few specialized tools, pressure testing, orifice size req., and burner BTU. to go much further than cleaning the dust out of the burner, and cleaning the orifice.

Hope that helps, and thank you.

Yes you can convert to LP gas. go to this web site to get the parts.

Go to page 9 and look at parts # 57 - 60 that is the part you need to change. You need to know the sea level that you are at though so you get the right part.
Now if you go to page 8 you will find where it goes part # 53 thru 61
