PPT-Gas Furnace Controls

Part 2 Gas furnace controls part 1 reviewed Group I of the four groups of controls systems Part 2 will review Group II The next slide will show all four groups as a review Please refer to page A1 in your Student Handout Packet.

The manifold regulation should stabilize after about 20 seconds and stay within +/- 10% of the set pressure setting. METALS. Types. Ferrous metals.
