They had troubles with having a broiler in the top of the gas ovens. The pilot light would not stay lighted so they were forced, in the more expensive lines, to use electric ignition for the broiler, put the broiler next to the oven in 40" models or do what most of the gas 30" models did, have the broiler in a pullout drawer between the cooktop and the bottom of the oven which ruined the lines of the range. In an apartment building, I saw a Welbuilt 30" with lower oven and glass door upper oven. The upper oven burner was raised maybe 6 inches above the floor of the oven and you could broil under it. With the puny heat output and no MicroRay broiler burner, there was no danger of food being too close to the flame.
