Hi Folks,
New person here looking to see if anyone has experience working on torpedo heaters or if anyone has experienced the same problems I have with mine. I purchased a ProCom Magnum PCK 110VT construction heater for my garage about 16 months ago and it only works 25% of the time (automatic or manual mode). It's a 80-110K BTU, multi-fuel heater with about 40 hours (when it does run). The problem started the first few days after placing into service where I started getting error codes. Anything from No Fuel, spark, Airflow changed, Pump pressure wrong, etc. Last winter was warm in the north east and my garage is insulated/finished so I didn't use it much and basically forgot about it - till this year (we have had 15 sub-zero days and over 800 hours of below freezing temps). I contacted the Mfg. and after numerous attempts I got an engineer who told me that based on the serial number the heater had a defect that would throw random error codes. It was apparently the plastic side cover that had a molded protrusion that when installed on the heater would actually pinch the vacuum line to the nozzle. I had already had the heater apart numerous times trying to figure it out but when the cover if off you didn't see the problem. Anyway, I removed the molded plastic and thought I had it fixed. Same issue with not working but now the unit won't fire off if the top cover is on and will only fire 50% of the time with the top cover off. Error code indicates numerous items to troubleshoot/replace. What I've tested and changed - The heater gets fuel (plenty), the ignitor glow bright red, the fuel atomization is great and the pump pressure is right on spec. I have replaced the ignitor, nozzle, fuel filter, and vacuum lines and have tested/inspected the fuel pump and set to factory specs on tolerance - to no avail. I can see the unit start up - the ignitor comes on for 8 seconds then the fan/pump kicks in and the fuel sprays out perfectly, just not close enough to the ignitor to spark most of the time. I know I got a lemon with this model but for the life of me I can figure out why it won't lite off every time. I think the combustion chamber nozzle/ignitor mount is defective or the nozzle is the wrong spray pattern or the pump has a defect that does not keep the pressure spot on. That is the only thing I haven't replaced and frankly I'm not. Any ideas before I introduce the next series of test which will be a Sledge Hammer?
Thanks.
