If you'd haven't already done so, we recommend reading the quick 'set up' guide for HOTTAP v2 by clicking here
Ensure that the shower handle switch is in the “off” position.
Turn the gas on by twisting the cylinder valve knob in an anti-clockwise direction one full turn.
Open the valve at your water source. Please note that, since the shower handle switch is in the “off” position, water should not be flowing through the showerhead
You can now control the entire system at the shower handle switch. Flick it on: the water starts to flow and the Hottap burner automatically ignites. Flick it off: the water flow stops and the Hottap burner automatically extinguishes.
Bearing in mind that the water might be very hot, stand clear of the shower when turning it on.
Step 5) Setting your temperature
Adjust the red flame lever and the blue water flow dial to find your desired temperature and flow rate.
For higher temperatures, turn the flame up and the water flow down.
For lower temperatures, turn the flame down and the water flow up.
