ALTERATION, SERVICE OR MAINTENANCE IGNITOR / FLAME SENSOR ASSEMBLY CAN CAUSE DEATH, SEVERE INJURY AND/OR PROPERTY DAMAGE. Perform the safety shutdown test anytime work is done on a gas system. NOTE: Read steps 1-7 below before starting safety shutdown or safety lockout tests for the ignition module. I 1 1. Turn gas supply off. 2. Set the thermostat or controller above room temperature to call for heat. Jl. 3. Watch for ignition spark immediately or following pre- purge. See ignition module specifications. 4. Time length of ignition operation. See ignition module specifications. 5. After the module locks out, open gas control and ensure there is no gas flow to main burner. 6. Set the thermostat below room temperature and wait one minute. 7.
