Check voltage to electrical outlet. Ifvoltage is good, check heater powercord for breaks2. Adjust motor/fan mount to keep fanfrom hitting inside of heater shell. Bendfan mount if necessary3. Replace fan. See Fan, page 94. Replace motor. See Motor, page 81. Repeat installation and operationinstructions. See Installation, page 4and Operation, page 52. A) Check ignitor wire. Tighten orreattach loose ignitor wire. See Figure10, page 9 for ignitor wire locationB) Set gap between ignitor electrode andtarget plate to .13"/.15" (3.3 a 3.8 mm)C) Replace ignitor electrode. SeeIgnitor, page 10D) Replace spark transformer. SeeSpark Transformer, page 91. A) Refill tankB) Provide additional and/or largertanks. See Propane Supply, page 42. This can happen when running heaterin temperatures above 85°F. Runheater in cooler temperatures3. Check heater inlet and outlet. Re-move any obstructions4. Replace fan. See Fan, page 85. Clean heater. See Maintenance,page 51, Check all connections for leaks. Ap-ply mixture of liquid soap and waterto gas joints. Bubbles forming showa leak that must be corrected2. To obtain correct mixture of propane/LP gas and air, use a larger cylindersize, i.e. 40 lb.(minimum) or 100 lb.See Propane Supply, page 43. A) Use a larger supply cylinder size,i.e. 40 lb. (minimum) or 100 lb.B) Reduce consumption rate by op-erating the heater at "LOW" settingtemorarily until frost disappears fromthe tankPOSSIBLE CAUSE1. No electrical power to heater2. Fan hitting inside of heatershell3. Fan blades bent4. Defective motor1. User did not follow installa-tion or operation instructionsproperly2. No spark at ignitor. To test forspark, follow step 8 under Ig-nitor, page 10. If you see sparkat ignitor, have heater servicedby qualified service person. Ifno spark seen:A) Loose or disconnectedignitor wireB) Wrong spark gapC) Bad ignitor electrodeD) Bad spark transformer1. Propane supply may be inad-equate2. High surrounding air tem-perature causing thermal limitdevice to shut down heater.3. Restricted air flow4. Damaged fan5. Excessive dust or debris insurrounding area1. Gas leak2. Heater operating on a 20lb. pro-pane/LP cylinder. Insufficientpropane/LP gas will be supplied bya 20lb. cylinder resulting in odor3. Propane/LP supply tank is"freezing up". Evaporationand consumptioin rate of pro-pane from supply tank is togreat for the size of the tankand air temperatureOBSERVED FAULTFan does not turn whenheater is plugged inHeater will not igniteHeater shuts down whilerunningHeater producing odorWARNING: Use only in areas free of high dust content.
