Reset is accomplished by removing power from the module for at least five (5) seconds (thermostat cycle required.) 9. On a three-trial module, if flame is established and lost on the first or second trial, the gas valve is turned off, a purge, warm-up, and trial for ignition will occur on a three-trial module, only three trials for ignition are allowed per thermostat cycle. Maintenance For best performance, the following maintenance procedures should be performed before each heating season: 1. Be sure gas and electrical supply to heater are off before performing any service or maintenance. 2. Check condition of blower scroll and motor. Dirt and dust may be blown out with compressed air, or a vacuum cleaner may be used. 3. Check condition of burner. Carefully remove any dust or debris from inside the burner box or burner cup. 4. Inspect the igniter. Replace igniter if there is excessive carbon residue, erosion, breakage or other defects. 5. Check the inside of the firing tube with a flashlight. If carbon or scale are present, scrape out the deposits with a wire brush or rod, or metal plate attached to a wooden pole. 6. Check to see that the burner observation window is clean and free of cracks or holes. Clean or replace as necessary. 7. Check the flue pipe for soot or dirt. After cleaning as necessary, re-attach the flue pipe to the heater. 8. Outside surfaces of heater may be cleaned by wiping with a damp cloth. 9. A qualified service agency should be contacted for service other than routine maintenance. 10. Check vent terminal and fresh air inlet to see that they have not been blocked during the non-heating season. If either pipe is restricted, the air switch won’t close, resulting in a no-heat situation. Troubleshooting CAUTION: Before opening the Ener-Radiant XL burner door for any type of service, be sure the gas supply has been shut off at the heater and the electrical cord from the burner box has been unplugged. Blower Motor 1. Is the thermostat calling for heat? Is there Fails to Run: 115V at the burner receptacle? 2. Check blower side door for seal. Check door switch. Replace if necessary/ 3. Check blower for obstructions. Replace blower if necessary. Igniter 1. Check igniter for damage. Replace if Does Not Glow: necessary. 2. Check voltage and resistance at igniter. (Voltage should be 115V. Resistance should be 40-75 ohms.) 3. Check for obstructions to the air inlet and outlet. 4. Check wiring and hose connections to the air switch. Replace if necessary. 5. Check voltages at transformer primary and secondary. Replace transformer or module if necessary. Valve Does Not Gas pressure downstream of gas control can Come On: be measure by using a manometer and connecting to pressure tap on control/ 1. Check to see if manual valve heater is ON. 2. Check to see if manual valve knob on heater gas control in ON. 3. Supply gas pressure can be checked at 1/8” NPT pressure tapping on heater external manual valve. 4. Check to see if gas control is opening: no manifold pressure indicates valve is closed. If the valve is closed, either the gas valve or the ignition module is faulty. WARNING: Do not disconnect ground leads inside heater. Do not interchange grounded and ungrounded leads on transformer or ignition module. Burner Does Not 1. Check to see if gas lines were properly Light: purged of air. 2. Check inlet and outlet gas pressure during ignition period. Natural inlet pressure should be 4.6” Natural outlet pressure should be 3.5” LP inlet pressure should be 11.0” LP outlet pressure should be 10.25” 3. Check for proper orifice and air plate. Burner Does Not 1. Check ground wire continuity. Stay Lit: 2. Check burner internal wiring for reversed leads. 3. Check insulation on the igniter leads. 4. Replace module if necessary. Honeywell Valve LED Status The Ener-Radiant XL series Tube Heater is equipped with a honeywell Smart Valve. This valve has a built-in diagnostic program, which will assist in troubleshooting in the event of a valve-related problem. The LED or (Light Emitting Diode) is located on the top of the valve as shown in diagram below. The LED status indications are listed below to help with the troubleshooting. FIGURE 22: OFF INDICATED Off No power to the control Bright-Dim Normal operation. This indication shows whenever the system is powered, unless some abnormal event has occurred. 2-Flashes Airflow providing switch remains closed longer than 30 seconds after call for heat begins (air providing switch stuck closed.) 3-Flashes Airflow providing switch remains open longer than 30 seconds after combustion air blower is energized - or blower does not energize. 4-Flashes White jumper wire is loose. 5-Flashes Flame signal sensed out of proper sequence. 6-Flashes System Lockout.
