The electric button was like a standard starter button found on early petrol cars, it should be mounted on the chassis just inside the inspection flap, when pressed the battery was shorted through the pilot vaporiser, a high current passed through the pilot vaporiser heating it up, this was very hard on the battery.
The best way these days is to use a gas blowlamp on the pilot and pipework just outside the burner pan until sizzling hot, then place the blowlamp so that the flame passes through the peep hole and turn on the pilot fuel valve just a little, (1/8 turn) it should light with a blue flame, keep an eye on it for a few minutes, if it starts pulse from a blue to yellow flame apply more heat, try and keep the blowlamp flame away from the air intake for the pilot, watch the pilot burner through the peep hole until it settles to a steady blue burn, open the pilot valve up one turn.
Hope this helps, Jeff.
