PROPANE 2 (1)
RVTI LEVEL TWO FIRST PROPANE STACK
| Question | Answer |
|---|---|
| Describe conversions (btu rates) | INSERT EQATIONS |
| Describe advanced vaporization | |
| Describe wetted surfaces | |
| Describe principles of propane flow and need for regulators | |
| Describe propane flow through an RV | |
| Identify factors that impact internal container pressure | |
| Describe the principle related to container pressure regulator | |
| Troubleshoot advanced regulator issues | |
| Identify principles related to propane and container pressure | |
| Diagnose regulator equipment failures | |
| Replace and adjust a regulator | |
| draw basic propane system and label | |
| Gallons to Liters (1 US gal = 3.785L), (1 imp. Gal = 4.54 L) F° to C° [(F°-32) / 1.8] 11 in. water column (WC) = 6-1/4 oz/in2 pressure propane conversion formulas | |
| The heat transfer occurs primarily through the shell (container walls) wetted by the liquid. The lower the fuel level, the less the wetted surface and the lower the vaporization rate | |
| propane cannot be compressed into aliquid | |
| in winter temps its a goo idea to keep propane cont at least ____ full | 50 percent |
| boyles law is | pressure and volume of gas are inversely proportional to one another. So, if you push gas, its volume becomes smaller and the pressure becomes higher.Rise in Volume = Drop in Pressure (and vice versa)PV = K (P=pressure; V=Volume; and K=A Constant) |
| draw single stage regulator | |
| DRAW TWO STAGE REGULATOR | |
| AUTMATIC CHAGNEOVER RAEGULATOR | |
| rise in volume = drop in pressure ( and drop in pressure= rise in volume ) is for _____. it is called ____ law | gas , boyles law |
| automatic changeover regulator is a two stage regulator designed to be connected to ______ propane cylinders | two |
| steps to turn on automatic changeover device (1) | (1) make sure all appliances and pilot lights are tuned off |
| steps to turn on automatic changeover device(2) | (1) turn off apps and pilots (2) have gas in both cylinders and both pigtails connected |
| steps to turn on automatic changeover device(3) | (1) turn off apps and pilots (2) have gas and both pigtails connected (3) rotate selector to first use cyl(service cyl. other one is 'reserve') |
| steps to turn on automatic changeover device(4) | (1) turn off apps and pilots (2) have gas and both pigtails connected (3) rotate selector to first use cyl. (4) open cyl valves and wait until light up green before trying pilots or apps |
| in changeover reg, if pilot lit before pressure turns green what happens? | low gas pressure will be fed to appliances |
