1. Schematic to Pictorial

Schematic to
Pictorial

2. You will now draw the Pictorial by following the Schematic

3. The process will be to follow the schematic one wire at a time from one component to another component until you are finished.

4. The slides that follow will show the wire in RED on the schematic that is going to be wired on the pictorial. Then the pictorial slide will show that wire being ‘installed.’ This is the wire you are to place on your pictorial. Keep advancing through this slide presentation until you are finished with the pictorial.

5. Moving onto the next voltage: the 24v ‘Control’ LOW VOLTAGE circuit.

6. This page has the whole circuit shown
This page has the whole circuit shown. But let’s move onto the next screen where there will be a ‘closer’ view of the 24v circuit.

8. Please use page G7b
for the low voltage
‘control’ circuit.

10. P C Label the transformer ‘P’ and ‘C.’ It does not matter
which side is the ‘P’ or ‘C’
unless the manufacturer
identified the ‘P’ and ‘C.’ P C

23. G7c, the 120v circuit page, requests the gas valve circuit be added also. I do not do that on page G7c, but it is on this page, G7b.

24. P C Notice the ‘Pilot Generator.’ This is a 750mv Powerpile
thermocouple. It produces
the voltage (mv) necessary
to operate the mV gas valve.
The gas valve is a mV gas
valve and not a 24v gas valve. P C

26. The next slide shows your completed PICTORIAL and this is what you need to show your Instructor for credit.
