V. Piping and Trim WARNING Failure to properly pipe boiler may result in improper ope ra tion a nd damage to boile r or structure. Oxygen contamination of boiler wa te r w ill cause c orrosion of iron and steel boiler c omponents, a nd c an lead to boiler failure. Burnham's Standa rd Warranty does not cover proble ms caused by oxygen contamination of boiler wa te r or scale (lime) build-up caused by frequent addition of w ater. A. Design and install boiler and system piping to prevent B.
Figure 24: Steam Boiler Piping (Minimum) NOTICE Failure to pipe boiler as specified in this manual may result in excessive system noise, water line fluctuations and water carry over.
Figure 25: Water Boiler Piping for Circulator Zoned Heating System
Figure 25A: Water Boiler Piping for Zone Valve Zoned Systems
E. Alliance Indirect Water Heater (if used). Refer to Alliance Installation, Operating and Service Instructions for additional information. 1. Steam. See Figure 2 for tapping locations. a. Supply and Return Piping. Connect supply piping to Tapping "N" (1¼ NPT) and return piping to Tapping "M" (1¼ NPT). Install zone circulator and strainer in supply piping. Install check valve to prevent gravity circulation of boiler water. b. Limit. See Figure 23.
VI. Gas Piping jurisdiction specifies a gravity factor be applied. For specific gravity greater than 0.70, apply gravity factor from Table 5. If exact specific gravity is not shown choose next higher value. WARNING Failure to properly pipe gas supply to boiler may result in improper operation and damage to the boiler or structure. Always assure gas piping is absolutely leak free and of the proper size and type for the connected load. An additional gas pressure regulator may be needed. Consult gas supplier.
4. All above ground gas piping upstream from manual gas valve must be electrically continuous and bonded to a grounding electrode. Do not use gas piping as a grounding electrode. Refer to the National Electrical Code, ANSI/NFPA 70 and/or CSA C22.1 Electrical Code. ½ psig or less, isolate boiler from gas supply piping by closing boiler's individual manual shut-off valve. 2. Using soap solution, or similar non-combustible solution, electronic leak detector or other approved method.
VII. Venting WARNING This appliance needs fresh air for safe operation and must be installed so there are provisions for adequate combustion and ventilation air. Read, understand and follow combustion air instruction restrictions contained in the PreInstallation instructions of this manual. Do not operate appliance where gasoline or other flammable vapors or liquids, or sources of hydrocarbons (i.e. bleaches, cleaners, chemicals, sprays, paint removers, fabric softeners, etc.
1. Seal any unused openings in the common venting system. D. Install Vent Connector from draft hood or vent damper to chimney. See Figure 30. 2. Visually inspect the venting system for proper size and horizontal pitch and determine there is no blockage or restriction, leakage, corrosion, and other deficiencies which could cause an unsafe condition. 1. Do not connect into same leg of chimney serving an open fireplace. 2. Vent pipe to chimney must not be smaller than outlet on draft hood or vent damper.
VIII. Electrical DANGER Positively assure all electrical connections are unpow ered before attempting installation or service of electrical components or connections of the boiler or building. Lock out all electrical boxes w ith padlock once power is turned off. WARNING Failure to properly wire electrical connections to the boiler may result in serious physical harm. Electrical pow er may be from more than one source. Make sure all power is off before attempting any electrical work.
1. Provide individual branch circuit with fused disconnect. Boiler is rated for 120 VAC, 60 hertz, less than 12 amperes. Set heat anticipator to match system requirements. See Table 6. In general, setting heat anticipator too low will cause boiler to short cycle without bringing heated space up to temperature. Setting heat anticipator too high will allow boiler to operate longer than necessary and overheat space. 2.

FOR YOUR SAFETY READ BEFORE OPERATING WHAT TO DO IF YOU SMELL GAS: WARNING Do not try to light any appliance. Do not touch any electric switch other than the gas valve; do not use any phone in your building. Immediately call your gas supplier from a neighbor's phone. Follow the gas supplier's instructions. If you cannot reach your gas supplier, call the fire department. 3. Use only your hand to slide the gas control switch to "ON". Never use tools.

d. Intermittent Ignition (HSP), Models IN3 through IN9. See Figure 61. Pilot should be lit only after completing Step 3. Pilot burner produces three (3) flames. Center flame should be steady, medium hard blue enveloping 3/8 to ½ inch of sensing probe. WARNING Failure to properly adjust gas input rate will result in over firing or under firing of the appliance. Improper and unsafe boiler operation may result. 2. Adjust thermostat to highest setting. 3. Check main burner flames. See Figure 62 or 63.
Table 7: Input Rate 3. Gas valve has step opening regulator which initially opens to 1.4 or 2.5 inch w.c. and steps to full pressure after approximately 30 seconds. Check manifold pressure after step has occurred. Adjust gas valve pressure regulator as necessary for 10.0 inches w.c. (turn adjustment screw counterclockwise to decrease manifold pressure, or clockwise to increase manifold pressure). If 10.0 inches w.c. can not be attained, check gas valve inlet pressure. If less than 11.0 inches w.c.
a. Run 1 NPT pipe from Surface Blow-Off Tapping "L" to open drain. Do not install shut-off valve or other restriction. See Figure 2. d. Fill boiler to normal water line. Follow Lighting or Operating Instructions to place boiler in operation. See Figure 53, 54, 55, 56 or 57. b. Fill boiler to top of gauge glass. e. Operate boiler for at least 30 minutes after condensate begins to run hot. Follow instructions TO TURN OFF GAS TO APPLIANCE. See Figure 53, 54, 55, 56 or 57. c. Remove safety valve. d.
2. Make pH or Alkalinity Test. testing with Hydrion paper which is used in the same manner as litmus paper, except it gives specific readings. A color chart on the side of the small Hydrion dispenser gives the reading in pH. Hydrion paper is inexpensive and obtainable from any chemical supply house or through your local druggist. The pH should be higher than 7 but lower than 11. Add recommended water treatment chemicals, if necessary, to bring the pH within the specified range.
X. Service Instructions DANGER This boiler uses flammable gas, high voltage electricity, moving parts, and very hot water under high pressure. Assure that all gas and electric power supplies are off and that the water temperature is cool before attempting any disassembly or service. Assure that all gas valves and electrical disconnect switches are off before attempting any disassembly or service. Do not attempt any service work if gas is present in the air in the vicinity of the boiler.
Figure 64: Boiler Flueway Cleaning Check float for evidence of collapse. Check mercury bulb (where applicable) for mercury separation or discoloration. Do not attempt to repair mechanisms in field. Complete replacement mechanisms, including gaskets and instructions, are available from low water cutoff manufacturer. c. Five (5) Years or 100,000 switch cycles. Replace switch and float mechanisms. Remove all obstrutions. Replace all deteriorated parts and support properly. Seal all joints. E.
H. Install Burners by reversing procedures used to remove burner. Main burners must be in slots in rear of burner tray and seated on main burner orifices. Reconnect pilot gas supply, and thermocouple lead (continuous ignition) or igniter/sensor/ground. See Table 8 for Pilot Burner location. Table 8: Pilot Burner Location Pilot Located B etween B urners* F. Remove Burners for cleaning, changing orifice plugs, or Boiler Size repairs. 1 inch 40m m IN3 1& 2 1& 2 3.
