will either be the unitrol control box or the thermocouple, when you push down you are holding two magnets together and waiting for a small charge to be created from the probe in the flame , if this is not working you have no charge and the magnets won;t stick to allow the valve to open, change the thermo and see if that works first, its way cheaper than a new controler

flame sensor rod is probably not bad but just has a soot build up on it. take some steel wool or I use a soft brass brush and make the rod shine. DO NOT USE ANYTHING COARSE, if you scratch the rod it will rust, then it is bad

It may be, Rinnai suggests a maximum length of about 13 equivalent feet of venting including elbows. Add 6 feet for every 90 degree elbow. If the vent is longer than this it is taxing the combustion fan motor and it will start giving you error codes and will not ignite. Remove the trim panel from behind the heater and find the flexable air intake pipe. Temporally remove it from a fitting and test the unit a few times to see if the unit starts quieter. This procedure will be taking room air into the heater for combustion and circumventing the direct vent feature of the heater, not a fix. Have you had the gas pressure tested? It gould be that! You may wish to consider relocating the heater and fire your installation contractor for putting you in this predicament, not Rinnai.

Testimonial: "Thanks very much. Please see comments."
I had this problem. From using the center brick most of the time, lots
of dust bunnies build up in the gas chimney behind the brick.
Tie 2 pipe cleaners together with a small perpendicular circle at the top and carefully remove the dust bit by bit by twirling the cleaner.
The brick should fire like new if it is carefully cleaned out.
