OK. Here goes--from a non-electric savvy guy.
Attached is a scan of the little box the timer came in.
This one is an Intermatic Model #FD12HWC manual timer (You spring wind to desired amount of time)
This one was primarily for a hot tub operation but works on my water heater.
It has four connection points on the side towards the back.
One side is labeled 1A and 1B. The other side is labeled 2A and 2B.
I used ONLY the 1A &1B (because they are on the side closest to my water heater control.)
On the timer the wires are retained by screws.
You will have to access the back side of your existing water heater switch. I unscrewed the little switch panel and pulled it out far enough to get at the two wires on the back of the switch.
I removed about 1/2" of wire insulation from each of the two wires and then meshed my wires from the timer--one wire from 1A & one wire from1B. It does not matter which wire goes to which wire on the existing heater switch.
I soldered and then taped the wires onto the wires on back of the switch.
(for some strange reason, the top bayonet connector on my existing heater switch has two blue wires into the connector and I only tapped into one of the wires)
You will have to cut an opening--somewhere-- to fit the back part of the timer switch and just enough clearance for the two wires before wiring the timer in.
Test--then verify. try your existing heater switch on and off--Red light comes on? GOOD! Turn that switch off.
Rotate the timer clockwise--Red light on the old heater switch comes on?? GOOD!! Put everything into their respective openings.
Now you can use either option to control your water heater and your propane use.
