Having some issues with our Girard tankless water heater-model GSWH-1. The unit was installed by airstream adventures northwest, just over a year ago. It's been used... maybe twice. Airstream adventures northwest winterized the trailer and while getting the trailer ready for summer, I notice that all three water valves were turned off (see attached pics.) I've followed the instructions from the manufactures manual and watched the YouTube video. The instructions and video do not mention anything about these three valves. Needless to say... still without hot water.

I've tinkered with the valves, trying different positions, but perhaps not the correct ones. The unit is turned on and clicks when the hot water is running.

The LP is working, stove and oven work, refrigerator works on LP and the furnace is working.

Any suggestions would be appreciated.
Thank you!

do you have a shut off at the heater for the gas? sounds like its trying to fire up by the clicking but no gas to fire. Or maybe its a water pressure thing. I'm no expert just some thoughts. Wish I had the answer for you.
We have yet to hook up our tankless water heater so I hope you figure out the cause incase we run into this.

From your picture, it looks kind of like a standard by-pass for a water heater. For use, the blue pipe that runs vertically in your picture should be in the off position while both of the other two (red horizontal in the picture and blue horizontal in the picture) should be in the on position. If these valves work in the standard fashion, then a valve handle that is oriented across its pipe is "off" while a handle oriented along its pipe is in the "on" position.

Lynn (eubank) Thank you!!! I followed your advice, turned the valve off on the blue pipe that runs vertical and left the red and blue horizontal valves turned on... works perfectly. What an easy fix. Water ran for a few seconds and was nice and hot!!! Really appreciate your insight. (See attached photo of what it should look like!)

Thank you!

Any problems with your 'Girard tankless water heater', call the factory (number on back of manual), - their technician is extremely helpful. I had problems that were cased by me and he went out of his way to fix.
