IGNITERS AND FLAME RODS FOR -2, -3, -4-A AND -4-B BURNERS WITH A 90° AIR INLET
4445 IGNITERS AND FLAME RODS
To install igniters or flame rods it is best to remove the burner internal parts from the tile, so that the end of the electrode and insulator can be properly inserted into the appropriate hole in the stabilizer. It is possible to install new igniters and flame rods into the shorter burners without disassembling the burner but it’s very difficult with long burners. It is important that the ceramic insulator is properly supported as it passes through the access hole in the stabilizer and that the metal electrode dœs not contact anything once installed. If the igniters ceramic insulator is cracked where is passes through the stabilizer the spark could ground out, which will prevent the ignition spark from lighting the burner.
Replacement igniters and flame rods are available for all 4445 burners. Because many North American igniters are made with common electrodes, use this bulletin to find the replacement electrode part numbers, and not a number on the electrode body. It’s a good idea to keep extra spark igniters and ignition cables as spare parts. To determine the correct part number, measure the length of an existing part or check the last letter in the burner model designation and consult the tables below For example, a 4445N-3-MRH-RM is a “Medium” length burner which uses igniter 4-56298-2 and flame rod 4-56299-2.
