Motor will start. Fan will turn, forcing air out front of heater. 4. Open propane supply valve on propane tank(s). 6 OPERATION Continued A WARNING Be sure motor and fan are running before pushing in automatic control valve button. Flames could flash outside heater if motor and fan are not running. 5. Push in and hold automatic control valve button (see Figure 5). Push piezo ignitor button (see Figure 5). You may need to push piezo ignitor button 3-8 times until the burner lights. When burner lights, keep automatic control valve button pushed in for 30 seconds. Note: If heater fails to ignite, hose may have air in it. If so, keep automatic control valve button pressed and wait 20 seconds. Release automatic control valve button and wait 20 seconds for unburned fuel to exit heater. Repeat step Figure 5 - Automatic Control Valve Button and Piezo Ignitor Button Notice: If heater is unplugged or power outage occurs while heater is running, the thermal limit device will stop fuel flow. A few seconds occur before the thermal limit device activates. During this short time, flames may appear outside the heater. This is normal. The flames will go out when thermal limit device activates. To Stop Heater 1. Tightly close propane supply valve on propane tank(s). 2. Wait a few seconds. Heater will burn gas left in supply hose. 3. Unplug heater. To Restart Heater 1. Wait five minutes after stopping heater. 2. Repeat steps under To Start Heater, page 6. To Change Propane Tank(s) Change propane tank(s) in a flame-free area. Use only propane gas, I3P. 1. Tightly close the propane supply valve(s) on the propane tank(s). 2. Disconnect the hose/regulator assembly from the propane tank(s). 3. Connect the hose/regulator assembly to the new propane tank(s). Tighten firmly. 4. Check all connections for leaks. A WARNING Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once. 7 STORAGE A CAUTION Disconnect heater from propane supply tank(s). 1. Store propane tank(s) in safe manner. Follow all local codes. Always store propane tanks outdoors. 2. Place packing items on the heater and hose/regulator assembly. Place heater and hose/regulator assembly into heater carton. 3. Store in dry, clean, and safe place. Do not store hose/regulator assembly inside heater combustion chamber. 4. When taking heater out of storage, always check inside of heater. Insects and small animals may place foreign objects in heater. Keep inside of heater free from combustible and foreign objects. Remove motor and other internal parts if needed to remove foreign objects (see Service Procedures, page 10). MAINTENANCE A WARNING Never service heater while it is plugged in, connected to propane supply, operating, or hot. Severe burns and electrical shock can occur. 1. Keep heater clean. Clean heater annually or as needed to remove dust and debris. If heater is dirty or dusty, clean heater with a damp cloth. 2. Inspect heater before each use. Check connections for leaks. Apply mixture of liquid soap and water to connections. Bubbles forming show a leak. Correct all leaks at once. 3. Inspect hose/regulator assembly before each use. If hose is highly worn or cut, replace. 4. Have heater inspected yearly by service person. 5. Keep inside of heater free from combustible and foreign objects. Remove motor and other internal parts if needed to clean inside of heater (see Service Procedures, page 10). 6. Clean fan every 500 hours of operation or as needed. 8 TROUBLE- SHOOTING _A WARNING_ Never service heater while it is plugged in, connected to propane supply, operating, or hot. Severe burns and electrical shock can occur. OBSERVED FAULT Fan does not turn when heater is plugged in. POSSIBLE CAUSE No electrical power to heater Fan hitting inside of heater shell Fan blades bent Defective motor REMEDY Check current to electrical outlet. If current is good, check heater power cord for breaks. Adjust motor/fan guard to keep fan from hitting inside of heater shell. Bend fan guard if necessary. Replace fan. See Fan, page 11. Replace motor. See Motor, page 10. Heater will not ignite. User did not follow installation or operation instructions properly No spark at ignitor. To test for spark, follow step 9 under Ignitor, page 12. If you see spark at ignitor, have heater serviced by qualified service person. If no spark seen: A) Loose or disconnected ignitor wire B) Wrong spark gap C) Piezo ignitor loose D) Bad ignitor electrode Repeat installation and operation instructions. See Installation, page 5 and Operation, page 6. A) Check ignitor wire. Tighten or reattach loose ignitor wire. See Figure 13, page 12 for igni-tor wire location. B) Set gap between ignitor electrode and target plate to 4.3 mm. C) Tighten nut holding piez...
