We bought a 1983 motor home and there was no manuals and we are having trouble with the oven not working, the primary pilot light is working fine,but the Heater Pilot Flame not coming on. we think that it is the original 4 burner stove/oven built in in 1983. Can somebody help us with either a manual or where to get one or get it worked on. We live in Arizona, and we are restoring the motor home and sure could use some help. Thanks
