Resumen del manual
Rinse washer thoroughly. • Operations such as sawing, blowing, tearout and spraying may generate airborne fiber concentration requiring additional protection. First aid measures: • Eye contact - Flush eyes with water to remove dust. If symptoms persist, seek medical attention. • Skin contact - Wash affected areas gently with soap and warm water after handling. TO PLACE IN OPERATION 1. Be sure boiler has been correctly filled with water. 2. Follow correct lighting/operating instructions on boiler. For CG propane gas boilers only: WARNING Your propane supplier mixes an odorant with the propane to make its presence detectable. In some instances, the odorant can fade, and the gas may no longer have an odor. Propane gas can accumulate at floor level. Smell near the floor for the gas odorant or any unusual odor. If you suspect a leak, do not attempt to light the pilot. Use caution when attempting to light a propane pilot. This should be done by a qualified service technician, particularly if pilot outages are common. Periodically check the odorant level of your gas. Inspect boiler and system at least yearly to make sure all gas piping is leak-tight. Consult your propane supplier regarding installation of a gas leak detector. There are some products on the market intended for this pur- pose. Your supplier may be able to suggest an appropriate device. 3. If boiler starts, go to Step 5. If boiler fails to start, go to Step 4. 4. If boiler fails to start, check for following conditions: a) Loose connection or blown fuse? b) Limit setting below boiler water temperature? c) Thermostat set below room temperature? d) Gas not turned on at meter and boiler? e) Incoming natural gas pressure less than 5" W.C. or propane less than 11" W.C.? f) Access panel not secured in place? g) If above fails to eliminate the trouble, refer to Control Supplement. 5. Make sure boiler goes through several normal operating cycles. 6. Turn thermostat or operating control to desired setting. CHECK PILOT BURNER FLAME 1. Proper pilot flame a) Blue flame. b) Inner cone engulfing pilot flame sensor. c) Pilot flame sensor glows cherry red. 2. Improper pilot flame. a) Overfired - flame is large and lifting or blowing past pilot flame sensor. b) Underfired - flame small; pilot flame sensor not engulfed by inner cone. c) Lack of primary air - flame tip yellow. d) Pilot flame sensor not heated properly. CHECK BURNER FLAME 1. Proper burner flame, see Figure 11. Yellow-orange streaks may appear - caused by dust. 2. Improper flame: a) Overfired - Flames large. b) Underfired - Flames small. c) Lack of primary air - Yellow tipping on flames; sooting will occur. TYPICAL MAIN BURNER FLAME FIGURE 11 INSPECT VENTING SYSTEM 1. Check venting system at least once a month during heating season. With boiler firing, hold candle or match below lower edge of draft hood “skirt.” If flame does not blow out, but bums undisturbed, vent system is functioning properly. If flame blows out or flickers drastically, vent system must be checked for obstructions or other causes of improper venting. 2. Inspect all parts of venting systems for deterioration from corrosion, physical damage, sagging, etc. Correct all conditions found. 3. Verily damper is open when burner ignites. For additional information, see Control Supplement. TYPICAL PILOT BURNER FLAME FIGURE 10 Section VII: Check-out Procedure Check-off steps as completed. □ 1. □ 2. □ 3. □ 4. □ 5. DANGER Proper orifices must be used. _ Failure to do so will cause severe injury, death or substantial property damage. □ 6. Follow operating/lighting instruction label on boiler for proper start-up. Also refer to “lb Place in Operation,” page 11. □ 7. Proper burner flame? Refer to “Check Burner Flames,” page 12. □ 8. Test limit controls: While burners are operating, move indicator of high limit control below actual boiler water temperature. Burners should go off while circulator continues to operate. Raise indicator above boiler water temperature and burners should reignite. □ 9. Tfest any additional field-installed controls: If boiler has low water cut-off, additional high limit or other controls, test for operation as outlined by manufacturer. Burners should be operating and should go off when controls are tested. When controls are restored, burners should reignite. □ 10. Button on spill switch pushed in? □ 11. Tfest ignition system shut-off device: a. For standing pilot - TUrn gas cock knob to PILOT position and extinguish pilot flame. Pilot gas flow should stop in less than 3 minutes. Put system back into operation (see page 11). b. For intermittent ignition systems - Connect manometer to outlet side of gas valve. Start boiler, allowing for normal start-up cycle to occur and main burners to ignite. With main burners on, manually shut off gas supply at manual main shut-off gas valve. Burners should go off. Open manual main shut-off gas valve. Manometer should co...
