SYMPTOM POSSIBLE CAUSES CORRECTIVE ACTION 1. Burner will not light. A. Faulty Valve System. See Below. B. “OFF/ON” or wall switch defective. Disconnect the two black wires from the wire nuts. Test switch(s) for continuity with a multimeter. If continuity is not indicated, switch(s) is defective and must be replaced. Note:Before replacing“OFF/ON”switch, be sure to check wiring for loose connections or broken wires and repair as needed. 2. Burners come “ON” but go “OFF.” A. Burner orifice plugged. Check main burner orifice(s) for stoppage. Clean or replace. B. Obstructed vent system. Check vent system for obstructions. START • Turn Off Gas Supply • Assure Valve Switch Is In ON Position • Disconnect Control Harness • Set Thermostat To Call For Heat Insert A End View Of Control Harness Connector 24 Volt Hot 24 Volt Common 24 Volt Switched Check For Damaged Or Missing Terminals In Connector Igniter Terminals Insert B • Check For Proper Voltage At Control Harness (See Insert A). Voltage Should Be 24VNO Between Thermostat Or Pressure Switch And 24V Common And 24V Hot. 2 YES • Plug Control Harness Into Valve. Wait For Internal Check Delay. • Igniter Warms Up And Glows Red. NO • Replace Igniter/Flame Rod Assembly. YES YES1 • Turn On Gas Supply. • Pilot Burner Lights. NO YES • Main Valve Opens And Main Burner Lights. NO YES • System Is Okay. CHECK • Line Voltage Power • Low Voltage Transformer • Limit Controller • Thermostat • Wiring • With Pilot Burner Cable Connected, Measure NO Voltage At Valve HSI Element Output. 24V Nominal. (See Insert B) 1 2 YES • Replace Valve. • Measure Voltage Between 24V Hot And 24V Common Leads To Valve Control. Must Measure At Least 19.5 VAC With Igniter Powered (See Insert A). To Identify Proper Lead, This Check Must Be Done With The Valve Control Connected And Igniter Powered. NO • Replace Pilot Assembly. YES • Check Transformer And Line Volt Supply. • Check That Pilot Flame Makes Good Contact With Pilot Burner Flame Rod. • Check For Good Electrical Connection Through The Pilot Tubing. • If Both Of The Above Are Good, Replace Igniter/Flame Rod Assembly. YES NO Assure Plot Gas Tubing Is Purged. Recycle Call For Heat If Necessary. YES • Check That Pilot Gas Is Flowing. Wait To • Replace Valve. • Cycle Thermostat Off And Back On. • Main Burner Lights. NO • Replace Valve. 1 Igniter Will Cycle Off And Back On Once During The 90 Second Ignition Trial. All Voltage Measurements Must Be Taken While The Igniter When Measured Voltage At Connections, Use Care To Assure Terminals Are Not Damaged. Is Powered. 2 REPLACEMENT PARTS GAS CONTROLS — SIT MILLIVOLT No. DESCRIPTION Natural Propane Part No. Qty. Part No. Qty. 30. Gas Valve -SIT 43K0701 1 88J5301 1 31.
