The control box was modified twice. The first modification was a sealed control box instead of having the
timing blocks exposed. The second modification was to make the control box igniter-ready. If you have a
heater with exposed timing blocks, the new timing blocks are different. Follow the directions below to hook
up new timing blocks to the old stoves.
