48 Important Produc t Safety Information Refractory Ceram ic Fiber Product Warning : The Repair Parts list designates parts that contain refractory ceramic fibers (RCF).
49 SECTION IX: MAINTENANCE AND SER VICE INSTRUCTIONS A. MAINTENANCE OF LOW WATER CUT- O F F DEVICES W ARNING Probe and oat type low water cut-off devices require annual inspection and maintenance.
50 Operate the boiler with steam in the entire system for a few days allowing the condensate to return to the boiler . If the condensate can temporarily be wasted, operate boiler only for the length of time it takes for condensate to run clear .
51 by drawing a small sample of boiler water and testing with hydrion paper which is used in the same manner as litmus paper , except it gives specic readings.
52 SECTION X: BOILER CLEANING A. CLEAN THE FLUEWAYS (See Figure 27). 1. For access to the combustion chamber remove the two (2) 3/8" - 16 cap screws. If boiler is equipped with exible fuel line(s), swing door open. 2. Remove the two smoke box clean-out covers from the rear smoke box by removing the four 5/16"-18 hex head bolts.
53 Figure 27: Cleaning Boiler Flueways and Combustion Chamber Surfaces W ARNING The boiler must be connected to an approved chimney in good condition. Serious property damage could result if the boiler is connected to a dirty or inadequate chimney .
54 A. COMBUSTION 1. N O Z Z L E S — Although the nozzle is a relatively inexpensive device, its function is critical to the successful operation of the oil burner . The selection of the nozzle supplied with the MegaSteam™ boiler is the result of extensive testing to obtain the best ame shape and efcient combustion.
55 d. Excessive airow or draft causing ame to leave burner head. e. Excessive back pressure causing ame to be erratic. 3. Control locks out after T rial For Ignition (TFI). a. No oil to burner . b. Shorted electrodes. c. Nozzle clogged. d. Airow too high.
