Commercial Waste Oil Heaters / Reznor ra235 ignition issues.
« on: November 14, 2020, 04:38:39 am »
I have a ra235 that I have installed and I'm having trouble getting it to fire on its own.
It fired once the very first time I finished the stack install. It wouldn't restart so I pulled the assembly and had a carbon bridge on the electrodes so I plucked it off. After lighting the one time it won't fire.
So far I've adjusted the electrodes, cleaned the nozzle thoroughly, confirmed that the preheaters are hot and confirmed fog inside the chamber. I have confirmed via mirror that the electrodes gets a good arc and blows when the blower turns on. I've adjusted the gun position. The oil and air compressor pump aren't adjustable. I've talked with reznor support with no help. I can light it with a torch but will not light by itself even after letting it run and trying to restart warm after shutting down. I've changed the air band settings around from 0 to 4 on both and haven't set the draft regulator yet outside of the settings the reznor support suggested at initially 4. When I get it going with the torch it does puff white smoke out of the inspection door. I have not let it run for 5 minutes as I'm worried about doing damage.
I haven't found much luck hiring an hvac company to come look at it due to COVID-19 and the one I did find with experience told me to call reznor support.
