Old plumbing, and clogs can gather at elbows.
Plumbing repairs, faulty check valves etc can cause clogs.
Pressure gauge on water line can reveal if pressure drop is before or after the tankless unit.

If it can, then it is done with dip switch settings.
Read your product manual.
Switching types of gas, and messing with dip switches is dangerous.
LP gas burns much hotter than NG, and LP pressures are much higher than NG
Call Rheem with serial number and they might supply the information to you, but will likely tell you to call service technician... leaving you in exact same spot you are in now.

Undersized gas line?
Temperature set too high?
Haven't kept up with regular maintenance?
Tankless older than 5 years?
Hard water over 7 grains?

Might be able to help. Except L1 does not show on any error code file.
Copy following link for Rheem Richmond Ecosense etc computer water heater troubleshoot resources
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
Are you sure the error is not IL? Delime tankless.
Or UL flashes and indicates reset.
Or CL flashes and indicates fault history is cleared.
Or error 11 combustion failure? Call for service.
Or P1? Low water pressure, clean water filter check for leaks and crossover caused by bad single-handled faucet cartridge.
I recommend calling Rheem to find local technician who is qualified to work on tankless computers. Tankless are not ordinary water heaters, and they require continual maintenance to avoid common error codes, especially as unit gets 2-3 years old, after warranty has expired.
The required maintenance and expense of repairs, and general fact that people cannot make their own repairs, make tankless computers a bad choice for heating water.
If unit is 4-5 years old, it might be best to install tank-type heater for $385 from Lowes and cut losses.

1) I believe you can immediately elbow the PVC pipe.
There is a limit for how many elbows can be used between blower and termination, and limit is determined by diameter of PVC pipe.

2) Copy following link for venting resources and typical Rheem and Richmond power vent manuals, and diameter-elbow pdf from Bradford White.

3) Richmond is Rheem. Product manual will show specifications for venting.
Product warranty is voided if installation does not follow specifications shown in manual.
