Resumen del manual
Regulate the natural gas supply down from a minimum 6 inches water column to a maximum of 1/2 psi. The natural gas supply capacity should be able to supply a minimum of 100 cubic feet of gas at pressure for each heater connected to the system. Consult your natural gas supplier for proper sizing of the natural gas supply lines. Follow all local ordinances and codes. In the absence of local ordinances and codes, refer to the National Fuel Gas Code Handbook, NFPA54/ANSI Z223.1 and the Natural Gas Installation Code, CAN/CGA B149.2.

This is the check valve closing. To reset the excess flow check valve, close propane supply valve and open it again slowly. 5. Slightly depress and turn control knob counterclockwise to the low position (See Figure 6 or 7). Figure 6 - Control Knob and Piezo Ignitor Button Locations for Propane Model 3VH18A Running heater below specified input rating may cause flashback. During flashback, the burner flame is mostly yellow. The flame will burn inside the burner tube, causing a roaring noise. If flashback occurs, turn heater off. After burner tube cools, restart the heater. 6. With the control knob pushed all the way in, press and release the piezo ignitor button. Keep pressing ignitor button until the burner lights.
