Rinnai R85 Cut On

in THE MAIN WALL
How do I adjust my Rinnai to be more sensitive to water flow to initiate turn-on? I want it to turn on at a smaller flow rate. Now, my upstairs shower (turned all the way on) won't kick in the Rinnai. Likewise, my kitchen sink faucet (turned all the way on) won't kick in the Rinnai.

    Minimum flow is .6gpm

    to intitiate fire. No adjustment possible. It is a funciton of the CW inlet turbine calibration, the pcb and the gas valve. With the unit running hit and hold the up arrow on the touch pad for 2 sec. Then hit the on/off button and release both. It will read flow to the nearest tenth. Check the inlet filter as noted previously. I will typically turn a faucet on higher than I may want it to start the unit up and then adjust down. You may have to increase the flow to the faucet. I've drilled a small hole in the aerator in extreme circumstances.
