SERENGETI-IR™ BURNER ASSEMBLY must be securely and adequately grounded. This can be accomplished by wiring with a grounded, metal-clad raceway system, by using a separate ground wire connected to the bare metal of the blower frame, or other suitable means. 2.
Serengeti-IR™ Installation, Operation & Service TO START SYSTEM ! WARNING FIRE OR EXPLOSION HAZARD SYSTEM START / MAINTENANCE & SERVICE RESETTING THE IGNITION CONTROL The SERENGETI-IR™ BURNER ASSEMBLY is equipped with an automatic lockout control which is activated after 60 seconds if a burner should fail to ignite. If your burner should lock out, it should be reset by the following method: 1. Turn off the disconnect switch located near the burner or turn down the thermostat to stop the entire system.
MAINTENANCE & SERVICE CHECK SAFETY SHUTDOWN PERFORMANCE Serengeti-IR™ Installation, Operation & Service Radiant Tubing: NOTE: Read steps 1-7 below before starting safety shutdown or safety lockout tests for the direct ignition (DI) module. ! WARNING FIRE OR EXPLOSION HAZARD 1. Turn gas supply off. 2. Set the thermostat or controller above room temperature to call for heat. 3. Watch for ignition spark immediately or following prepurge. See ignition module specifications. 4.
Serengeti-IR™ Installation, Operation & Service ELECTRODES.) Check to see if high voltage leaks occur at porcelains and high voltage leads. 4. If ignition arc is not present or sporadic, turn off power and check gap. It should be approximately .10 inch. (DO NOT TRY TO MEASURE HIGH VOLTAGE OUTPUT.) High voltage wire should not touch casing as grounding can occur when wires are wet. 5.
MAINTENANCE & SERVICE ! WARNING Serengeti-IR™ Installation, Operation & Service ! WARNING FIRE OR EXPLOSION HAZARD FIRE OR EXPLOSION HAZARD IMPROPER INSTALLATION, ADJUSTMENT, ALTERATION, SERVICE OR MAINTENANCE CAN CAUSE DEATH, SEVERE INJURY AND/OR PROPERTY DAMAGE. IMPROPER INSTALLATION, ADJUSTMENT, ALTERATION, SERVICE OR MAINTENANCE CAN CAUSE DEATH, SEVERE INJURY AND/OR PROPERTY DAMAGE. 1. Flame is lit automatically. Do not light the flame manually. 2.
Serengeti-IR™ Installation, Operation & Service 5. The sensing probe detects the presence of the low fire flame and the control de-energizes the spark and the valve will remain open. Check valve outlet and other downstream pipe connections with a soap solution. 6. Turn the thermostat to a low dial setting to open contacts. The main gas flame should be extinguished. 7. For 100% shutoff check, set thermostat to low dial setting (system off). Disconnect sensing probe lead at control terminal. 8.
