I'd be interested in this info too. And Sam, I know you've been busy with the B&B, but how is your safety system coming along?

hi tura,
the guts of the safety system is pictured on page 3 of the manual. its basically a ts-11 type thermo magnetic safety valve, pilot assembly and thermocouple. the valve would be mounted between the manifold and the gas supply. im putting a system together with more readily available parts as well as a regulator and will be testing it soon.

Hi Tom,
Being that I'm a Model B gal myself, I don't have much knowledge about the Model C's. However, I do have the manifold/thermostat/stuff assemblies for several Model C's in my garage and would hate to dispose of an "automatic oven pilot" if I happen to have one. Is there a picture of one in the manual? If so, what page? If not, can you help me understand where to look for it and what it looks like?

Thanks!

The Robertshaw TS-11 was mounted on the floor of the service cabinet under the shelf. The pilot outlet on the thermostat was pluged. A pipe Tee was added to the gas filter between the manifold and filter, then tubing run to pilot input of the safety, then new pilot tubing run to the the Pilot assembly in the oven floor. The 3/8" burner output of the thermostat was run to the input of the safety, the safety output is run to the oven burner orifice. The Thermocouple was run to the safety. This provided complete cutoff of both pilot and burner gas to the oven should the pilot light go out.
Also, why do you want to add a regulator? I think that a regulator was added to ranges in normal production so that a service man would not have to go to the home to install a new range and adjust the fuel mixture. Big expense to save by the retailer. Also, The regulator will regulate the gas pressure to about 4", but the orifices and burners were designed for about 7". It is possible that you could not get the burner flames up to enough BTU for correct cooking and control.
And to add some more confusion, propane appliances do not use any regulation, other than the regulator on the propane tank.

I have the Robertshaw safety pilot manual here:

hey sam, welcome back and thanks for the info!
now i know why the old appliance club wants so much for their safety system.
i did it a little different, with cost being a major concern as well as ease of installation. it's not "factory" but it works.
re the regulator; i was having trouble keeping a consistant flame and tired of adjusting. i put a commercial propane regulator on thats set at 10"wc.
everything mounts out of sight under the pan.
maybe i should market it. [img]smile.gif[/img]
