NOTE: Before proceeding, all “light-off” permissive conditions must be satisfied. Initiate a start command to the SureFire™ igniter while observing the fuel pressure. The SureFire™ igniter ignites within 10 seconds from the time the fuel valve opens. The base of the flame should be blue and may change to a bright yellow as the flame travels into the furnace.
® TROUBLESHOOTING If the igniter does not light, check the following: • All fuel supply valves, including manual valves, are open. • Regulated gas pressure is available to the igniter. • Any valves in the gas lines are functioning properly. •...
Using compressed air to clean the tip, blow out the gas lines, both forward and backward. Inspect and clean the primary orifice located upstream of the removable fixed orifice. Replace the removable orifice in its original location. High Energy Igniter Remove and inspect the spark rod assembly every 6 months or during planned boiler outage, per the HEI Service Manual.
