• Seperate burner manual provided with burner. 2. Use pipe joint compound (pipe dope) resistant to corrosive action of fuel oil or liquified petroleum gases. Apply sparingly to male threads of pipe joints. Do not use any kind of pipe tape. 3. Oil piping – use flare-type fittings, not compression type. Do not use compression or soldered fittings. No safe repair can be made. Severe personal injury, death or substantial property damage will result. Propane boilers — see WARNING on page 39 regarding propane gas odorant. 16 Make final adjustments To fill water boilers: 1. Close manual air vents and drain cocks. 2. Fill to correct system pressure. Correct pressure will vary with each installation. 3. Starting on lowest floor, open air vents one at a time until water squirts out. Close vent. Repeat with remaining vents. 4. Refill boiler to correct pressure. To fill steam boilers: 1. Do not fill (except for leakage test) until boiler is ready to be fired. 2. Fill to normal waterline, halfway up gauge glass. 3. Recommend boiler water pH 7.0 to 8.5. Adjust burner and damper assembly: 1. Lock open flue transition damper. Make final burner adjustments using combustion test equipment to assure proper operation. Do not fire boiler without water. Sections will overheat, damaging boiler and resulting in severe property damage. 2. Refer to burner manual for start-up and service. 3. Let burner advance to high fire. Heat boiler to design conditions. 4. Using combustion test equipment, adjust burner for: a. 12% (± .%) CO2 for No. 2 fuel oil, 0 smoke. b. 9 – 10% CO2 natural gas; CO in flue gas not to exceed 50 ppm (0.01%). 5. Adjust damper assembly (Figure 35, page 33) to ensure 0.1" W.C. positive pressure at test opening. Tighten screws to secure in position. Plug test opening with 3/8" bolt provided with damper assembly. 6. Adjust barometric draft control, when used, to design conditions. 7. Repeat steps 4 through 6. Adjust as required.

Failure to properly clean can result in violent water level fluctuations, water passing into steam mains, or high maintenance costs on strainers, traps and vents. Skim boiler only. Do not clean old piping or leaks can occur. Do not use petroleum-based cleaning or sealing compounds in boiler system. Severe damage to system components can result, causing substantial property damage. 1. Remove 1." plug from skim tapping tapping “A” – Figure 28, page 29). Provide 1." skim piping from tapping to floor drain (pipe to side of boiler). 2. Raise waterline to midpoint of skim piping. 3. Fire burner to maintain temperature below steaming rate during skimming process. 4. Feed in water to maintain water level. Cycle burner to prevent rise in steam pressure. 5. Continue skimming until discharge is clear. This may take several hours. 6. Drain boiler. While boiler is warm but not hot, flush all interior surfaces under full pressure until drain water runs clear. 7. Remove skim piping. Re-insert plug at boiler skim tapping. 8. Close drain cock. Fill with fresh water to normal water line. Start burner and steam for 15 minutes to remove dissolved gases. Stop burner. 9. Check traps and air vents for proper operation. Determine if water treatment is needed (water boilers only): Do not use petroleum-based cleaning or sealing compounds in boiler system. Severe damage to system components can result, causing substantial property damage. Continual make-up water will reduce boiler life. Minerals can build up in sections, reducing heat transfer, overheating cast iron and causing section failure. For unusually hard water areas or low pH conditions (less than 7.0) consult local water treatment company. Freeze protection (when used): 1. Use antifreeze especially made for hydronic systems. Inhibited propylene glycol is recommended. Do not use automotive, ethylene glycol or undiluted antifreeze. Severe personal injury or death can result. 2. 50% solution provides protection to about -30°F. 3. Local codes may require back-flow preventer or actual disconnect from city water supply. 4. Determine quantity according to system water content. Boiler water content is listed on page 34. Percent of solution will affect sizing of heat distribution units, circulator and expansion tank. 5. Follow antifreeze manufacturer's instructions. Check boiler for gas-tight seal: Boiler must be sealed gas-tight to prevent possible flue gas leakage and carbon monoxide emissions, resulting in severe personal injury or death. 1. Remove boiler jacket side and top panels. The boiler contains ceramic fiber and fiberglass materials. Use care when handling these materials per instructions on page 38 of this manual. Failure to comply could result in severe personal injury. 2. Start burner. Observe all sealing points and chalk mark any n...
