Commercial Waste Oil Heaters / increased air pressure causing oil gauge fluctuation
« on: December 05, 2015, 03:44:12 am »
CB86AH when I increase air pressure for nozzle  it affects the oil pressure the pressure will fluctuate when I increase air pressure is this normal? The only thing I could think of is if the oring that is on the nozzle is bad it could cause air to try to override the oil pressure. The furnace is running and heating I  do see like dot or sparkles in the oil stream sometimes when it burns and just have a small amount of smoke from the vent stack. When I decrease oil pressure it will start to fluctuate on oil gauge if I decrease air pressure along with oil pressure it smooths out. I put a new pump on furnace this fall and have made sure all the connections are sealed on the oil suction side.

Does any one make a conversion kit that allows the older clean burn furnaces to have the swing away option? My furnace is mounted on the ceiling and is a pain to service I have to remove the gun and carry it down a step ladder to service it.

Waste Motor Oil / HELP CB-86AH oil pressure surges
« on: December 03, 2014, 04:48:46 am »
I have a older clean burn CB-86AH I am having issues with the oil pressure surging up and down it will fluctuate up and down about 1 and 1/2 pounds and the flame does the same it keeps going out due to eye not seeing fire eventually I have tried raising oil pressure and then it will over fire when it increase if I drop the pressure it will go out then reignite. I have purged the heater block, cleaned the oil filters on the suction side of pump, took pump apart and cleaned screen inside pump, tried a different batch of oil and it will run good for awhile then start surging again. Do any of you techs have any suggestions as what to check next?
I am running oil pressure at around 3 pounds and air at around 12 pounds according to my gauges. It does not sound like it is firing right either when it fires right it kind of makes a whistle noise and I have not heard that for a while. Could I have 1 of the 2 cal rod heaters bad?

Waste Motor Oil / CB-86AH heater block cleaning
« on: February 28, 2014, 05:15:11 am »
Does any one have an easy way to clean the carbon out of the heater block on this furnace? I removed the plugs and heaters and cleaned with a wire brush and flushed with diesel into a bucket with nozzle removed.
has any one attempted to use seafoam to remove the carbon I have thought about filling block with Seafoam and let it set with out any heat on the block then just purge the block while on the furnace. Any thoughts on this?
