Troubleshooting Fogatti Water Heater That Won't Ignite

Question:

I placed a low flow shower head on my RV for dry camping, Now my Fogatti tankless water heater wont ignite. Is there a way to adjust the flow rate so the water heater will operate at a lower flow?

The 40-45 psi preferred water pressure for the Fogatti RV Tankless Water Heater # LSB64FR has to do with the input pressure, not the output pressure. Installing a low flow shower head shouldn't be keeping the Fogatti from igniting since it would be the same as barely turning on a faucet. You can verify this is the case by removing that shower head and turning on the hot water to see if you get the same scenario.

Since the water heater won't ignite you'll need to check that the fuse is good, the power is on, and the gas pressure is correct. You can check the fuse and power switch on your own but you'll need to have a licensed technician come out and check the gas pressure so this can be done safely.
