## Questions & Answers

**Q: Electric panel is ~50 feet from where i want to install the tempra 29 trend. is this distance ok for #8 thhn wire?**
A: The recommended wire is 8/2 and there is not a limit to distance written in the install directions.
You need to check with your electrician. Make sure he is state license and insured. 
We have installed a Tempra 29 and our electrician ran three 8/2's approx. 30' with no question. But check with your electrician and local codes. God bless you and happy New Year.

**Q: Where is it made?**
A: The Tempra 29 is made in Holzminden, Germany, as of 8/16/2022.

**Q: How can i make tempra trend 24 work with my bosch shx33a05uc/22 dishwasher? the dishwasher will not advance to next cycle. water is not hot enough.**
A: This water heater activates at 0.5 GPM and will heat to your set temperature at the correct flow rate for that set temperature.  Please call our Technical Department at 1-800-582-8423  Ext 6 with more details so we can help you better.  (for example, does the dishwasher have its own heating element, distance between the 2 units, etc...)  Thank you.

**Q: Is there an installation kit available for this? i am installing in a remote location & plumbing parts are not available? water lines are pvc.**
A: There is no specific installation kit.   However, we suggest using flexible braided hose  connections that screw onto  the hot and cold water for the first 18" or so.  These connections are easy to remove to check a filter screen or if needed to work on the unit in general.  The connections are 3/4" NPT.  Please feel free to call our Technical Support Department at 1-800-582-8423  ext 6 with any questions.  Thank You.
