Some fryer valves have a safety lock, usually a slide on the handle near the valve body that must be released to open the valve. Check for this first. It's very rare for a fryer valve to stick unless it was forced shut with something partially blocking it. If not, let the fryer cool completely. Dip as much oil out as possible. Then disconnect the gas line and, with help, turn the fryer upside down draining the remaining oil into a suitable container. At this point, you have little to lose. Take a large wrench or piece of pipe to get more leverage and try to force it open and free it up. Do not use so much force that you damage the kettle. If you get it free, check to see that it does not leak before putting oil back in the fryer. If it leaks or fails to come free, replace the valve.
If the pilot won't light, the first thing to try is to replace the thermopile, assuming you have a good flame on the top portion of the thermopile in the first place when you hold the gas valve in when in the pilot position. If this does not solve the problem, which in 90% of the cases it will, the gas valve is defective. I usually replace the thermopile when replacing the gas valve and save the old one for a backup.
Hi There. You have not mentioned that you also replaced the spring inside the gas valve suited for propane, please check. I strongly advise not to modify the unit's ignition system nor bypass safety device, this is for your own good. Check the gas valve spring first.
I don't know that you can calibrate a thermostat on a deep fryer...Is your thermostat bad? Is the temperature setting off? Is it working at all? You could call Vulcan directly and ask for the parts/warranty dept and they could tell for sure if calibrating is possible or not... If not, and you need a new thermostat, then they can point you in the right direction for a dealer that sells their parts...
If I can help in any other way, call us at 888-542-5959. Thanks, Susan @ Restaurant Equipment Outlet, Cincinnati, OH.... www.restaurantequipmentinc.com
TO LIGHT THE PILOT
1.Open the door.
2. Turn the thermostat OFF The thermostat is located
behind the door.
3. Push the gas control valve knob and turn to OFF. Wait 5 minutes for unburned gas
4. Push and turn gas control valve knob to the "L" in PILOT.
5. While still holding the knob in, light the pilot with a lit flame. Continue to depress the
knob until pilot remains lit when knob is released. If the pilot does not remain lit,
repeat step 3 through 5.
6. Depress and turn gas control knob to ON
check the supplier for the conversion kit.the kit contains burner orifice, pilot orifice and gas valve spring which are commonly needed for conversion from propane to natural gas or from natural gas to propane. ****natural gas orifice has larger bore than propane, gas valve spring for propane is thicker than for natural gas.
You need to change the gas valve,burner orfices,pilot and maybe a gas regulator.I service these fryers often as im a hobart tech.Goto hobartcorp.com,type in your model and the parts list.Any ? let me know.
