On arrival set unit to call for heat ,unit responded ok ,noticed blower very dirty ,blower needs cleaning before we can proceed with the troubleshooting which could be the cause of unit not heating properly .unit is operating normal at this time but could stop anytime.

Upon arrival we replaced broken section of 3inch pvc in ceiling. Found access in barn so we didnt have to cut open ceiling. Once replaced we tested furnace and found exhaust pressure was better, but I still wasnt satisfied. Looked up installation manual and found that they suggest as much 3inch pvc as possible. We had 2inch coming off of unit, it 90 twice, then coupling to 3inch. Removed all 2inch piping and put reducer at top of furnace. All flue is 3inch now. Tested and found the same pressure if flue is on or off of furnace. Started up unit and regulated gas pressure. Tested unit and checked heat rise and operation. Unit now operating normal.

Upon arrival I replaced LP Kit on furnace. Went to run system and found venting issue, not pulling in pressure switch. Removed exhaust from furnace and found I was pulling 1.9 inches w.c. With flue attached I am only getting 1.2 inches w.c. Suspecting restriction or issue with flue pipe. Pipe is covered by ceiling. Went outdoors and inspected flue, found no problems. Hooked up vacuum to flue and found nothing restricting. Finally I put fish tape in exhaust and fed in pipe. Found 3inch coupling is disconnected and partially covering some of the flue. Customer had to leave so I couldn’t stay to repair. Need to return with 2 guys, at least 30ft of 3inch pvc, and 2 3inch 90s. Need to replace section of 3 inch pvc being fed outside from top of furnace. Furnace has been left off. Also need to regulate gas pressure once repaired.
