you can get it off the rinnai web site they have a spot on there to get the internet manuel,, but from what you are saying you may need to adjust the thermostat, or the temp, remember even though you will have endless hot water it still takes the smae amount of timed for the hot water to get to your faucet,, not only that make sure your shower heads aren't holding back to much water pressure, if you don't have enough water going thru the unit it will not stay lit, if will come on and go off, judt to dstisfy the unit,, make sure the filter is clear, on the cold side there is a cap screw if you take it off there is a screen in side you just pull it out and clean it and reinstal it,,

This is not an uncommon problem. You may notice this problem particularly if you haven't used hot water for a period of time. The hot water heater is probably working, but there is quite a bit of water that has to clear out of the lines before the hot from the heater reaches your appliance. I suspect that the water heater is doing its job, and that is the assumption I am going off of for my next statement. A recirculation system will work well to eliminate your problem. Again, assuming that the hot water heater is in proper working order. I would do my research on recirculation systems before buying one. Often times you get get a relatively inexpensive unit that will do the job for you.

If you aren't getting any error codes, then the heater is probably doing its job. Your problem is probably somewhere in your plumbing system. The most common reason you get this sort of problem is due to cold water mixing in the hot water system. There are a number of causes for a "cross connection" :
-Faulty check valve
-Missing check valve on reciculation return line
-Faulty shower cartridge
-Thermostatic mixing valve set too low
-Faulty thermostatic mixing valve
-Faulty anti-scald valve
The easiest way to confirm a cross connection is to: 1) shutoff the cold water entering the tankless heater 2) open hot water valves around the house. If you still have water flowing at your hot water fixtures, then you have a cross connection.
