Propane Fireplace-Convert back to Manual control from Remote?

#1
Hello, new to the forum. I have an older Patio Fireplace and looking to get it back to working order. It is a vent less propane for outdoor use. The tile facade has crumbled due to weather and some of the electronics look past repair. I no longer have the remote controller and not sure if the electrical circuitry would even work if I found it. I cannot find a Model or Make of the fireplace itself but have attached pics of the controls/valve. Is there anyway to convert this to a Manual fireplace with a flame control knob and keep it simple? Simply looking to get it working again and don't need convenience of remote. I would be happy to even have to manually light it each time vs buying a new fireplace. I am very handy but this is my first crack at a gas fireplace
