Look in the medicine cabinet in the bathroom, should be a turn dial knob with a flame color sticker around it.

Here are my procedures for using the hot water.

If cold out (water coming in is also cold) so I turn the knob in the medicine cabinet to just below max and go full hot on the shower. If the temp of the water is still not hot, start turning the pressure down by lowering the shower water handle until water is perfect. If it is to hot, turn the knob down a little.

When it's hot out, (water coming in is warmer) so I turn the knob to about half way and go full hot on the shower handle. If too hot, turn the knob down. If no hot enough, lower the pressure with the handle again.

I've used this method since getting my Berk and never had any issues. I've camped in the winter while in the 20's and summer well into the 100's. I will say that when it's below freezing out I use my water tank and the water is still very cold so my pressure in the shower is "low" to keep it nice and hot..... But it is still plenty of pressure and never run out of hot water...

Hello All,


First off thank you all for your help. I ended up calling Girard support. They were friendly and helpful. In the end it appears I had too much water pressure even with my Valterra water pressure regulator at 55 PSI. They wanted a meat thermometer and a gallon pail to run tests so be ready. The water is only where we accept the heat in the shower at 50% usage via the shower handle. Overall it's acceptable but no perfect compared to our gas/electric quick recovery 10 gallon tank we had in our 5th wheel. Going to try changing out the stock shower head with bodyspa Rv shower head next. Thanks so much once again!

I found that if I set the thermostat on the water heater to heat the water to a temperature that is comfortable to shower with without having to mix in cold water, that the water heater works very well. Also, as mentioned water pressure and air in the lines can also affect the water temperature.

If you have a chance, you might want to give setting the water heater so that you do not need to mix in any cold water a try before calling Girard.
Good luck.
That's a good idea, as long as the Mrs uses the same temp!

your tankless water heater

After reading everything concerning this on the Forum. I spent a Good 8hrs and 80 gallons of water to get it to work every time. First®. Bleed all faucets, it is a fact that you will need to get air out. Second®. Flush the toilets. Third®. Set temperature control around the 2 o'clock position.
Try it and see if you have sustained hot water. Let water run to simulate showering and adjust the temperature control.
Also, I shut off all valves I don't use on the water distribution manifold, I.e. washer/dryer, outside shower. Doing all I could to eliminate air buffering my flow and pressure.
Worked for me. Evertime.
O. Make sure you have propane. FR has had problems with regulators and Tank gauges. Tank gauge says full, tank is empty. Regulator is very sensitive..... Open valve slowly or regulator will sense high flow and shut off.
My DW told me to fix it or have Warren Buffet come get it. That's the toned down version.√¢£¥

Here's what I've been doing with the hot water adjustment, unless everyone hits the shower before I can get to it (at which point they just yell at me where to set it)…

Assume the dial in the medicine cabinet is +10 to +45 degrees. Run enough water to clear the hose so you're getting spigot feed (ignore this step if you're on your tank) and grab that digital meat thermometer you should already have in the kitchen drawer. If cold water is at 70 deg in the kitchen sink I set water heater control at about +20 or 25. If warmer about +15. My math is if I target hot water for showers at about 95 degrees, no one gets scalded, so if I'm really trying to get it right I will measure cold then target from there.

I was going thru my box of papers I got when I purchased my mh and found book on water heater and and to my amazement, it gave the exact way to make it work. It's funny how we pull our hair out trying to make it work and all we need to do is read the book. I'm guilty.

In my 38A, there is a temp control in the half bath cupboard. At the dealer they told me not to turn it to max...I have it at about 3/4 setting and hot water stays pretty consistent.

Do you have to do that every time you want to shower or is this a "set it and forget it" kinda thing?!

It is pretty much set it and forget it, but as gottawonder points out, you need to adjust it accordingly depending on the temperature of the incoming water. Colder incoming water you need to bump up the temp a bitl, warmer incoming water, turn down a bit.
