Girard tankless water heater - no power
Hello!
We are trying to install a Girard tankless water heater (the GSWH-2) from an electric/gas 6 gallon water heater.
We think we have everything hooked up correctly, but it seems like we have no power getting to the water heater. The on/off switch on the heater is on, 12V and -12V is connected (red and black), and heater has no power. The only wires that are not connected is the remote selector switch to choose gas or power.
Does the selector switch need to be connected also? We tried it and it ended up blowing a fuse (which has been replaced).
Any help would be greatly appreciated!
