ARE THERE INSTRUCTIONS


Call Rheem... and they might suggest local technician, or give you correct instructions and dip switch settings if that applies.
Otherwise Rheem does not post service manuals

Rheem RTG53DVP code 82


Before calling service technician, open following link for resources including error codes, Rheem chat and possible manual:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

Error codes are considered start-point for troubleshooting, and give service technician direction for isolating problem.
Error 82 appears as 'gas type data failure' > 'Program PC board for proper gas type.'

Gas type is choice between LP gas and NG natural gas.
Gas type programming is controlled with dip switch setting.
I do not have service manual for product, and would not suggest changing dip switches without specific information beforehand.

My unit is a paloma tankless model # PTG-74PVP its throwing error code C4 15 what does this mean? We believe its a flow problem because we hooked up an external pump, it starts out with full flow then...


Could be a restricted inlet pipe just as you suspected.
http://waterheatertimer.org/pdf/ErrorcodeTroubleshooting.pdf
error 15 is 'Boiling safety device'
"Check for closed water heater inlet valve or restrictions in cold water inlet pipe (must be fully open).
Check for clogged heat exchanger (scale buildup).
On commercial water heater, lower setpoint temperature below 180F at high altitude."

YOU MUST FOLLOW THE MANUFACTURERS CONVERSION INSTRUCTIONS EXACTLY. If you do not your homeowners policy COULD be declaired void in the event of a claim. More importantly (IMHO) you could create a dangerous situation!

30 gallon propane supply tank for residential home, seems appliances are burning too hot, flames are very high what is the cause? Regulator? O2 supply?


could you have gotten a natural gas tank by mistake? it would have larger orfices and allow more gas than you need propane has more B.T.U.s than nat gas and requires a smaller orfice
chack with your gas co.good luck.
