Before You Start Check to be sure you have the right size boiler before slating the installation. See rating and capacity fable on previous page. Also be sus the new boiler is 107 the type of gas you are using. Check the rating plate on the right side of the biter. You must see tha the boiler is supplied with the correct types of gas, fresh al for combustion, and a suitable electrical supply. Also, the boiler must be consented to a Suitable venting stern and an adequate piping system.
Fresh Air for Combustion Provision for combustion and ventilation air must be In accordance with Section 5.3, Air for Combustion and Ventilation, of | {he National Fue! Gas Code, ANSI revision, or applicable provisions of the local building codes. { WARNING Be sure to provide enough fresh air for combustion. Enough air insures proper combustion and assures that no hazard will develop due to the lack of oxygen.
Installation System Piping The near boiler piping, that is the piping around the boiler, must be considered as part of the boiler for proper water level control, and to produce dry steam. Correct near boiler piping is crucial fo the proper operation of the boiler and the heating system. Follow these recommendations carefully. t. Place boiler in selected location, as near chimney as possible, 2.
5. For installers choosing to use both supply tapping, Figure BA shows the correct way to pipe this system. Figure 8B shows the wrong way to pipe a header with twa risers. * Headers must be fitted with header offsets or swing joints, or be equipped with expansion joints, so halt thermal expansion and contraction of the header will not damage the boiler. Headers shall not be welded. » System takeoffs from the header must be between the equalizer and the riser to the header nearest the equalizer.

chimney and Vent Pipe Connection For boilers for connection to gas vents or chimneys, vent Installations shall be in accordance with Part 7, Venting of Equipment, of the National Fuel Gas Code, ANSI 2223. 1-latest revision and applicable provisions of the focal building codes. CHECK YOUR CHIMNEY This is a very important part of your heating system. ft must be clean, the right size, properly constructed and in GOOD CONDITION, No boiler can function properly with a bad chimney.
4. Place in operation the appliance being inspected. Follow the lighting instructions. Adjust thermostat so appliance will operate continuously. 5. Test for spillage af the draft hood relief opening after & minutes of main burner operation. Use the fame of a match or candle, or smoke from a cigarette, cigar or pipe. 8.
For safe, efficient operation, the vent damper and all flue product carrying areas of the appliance must be checked annually by you, with particular attention given to deterioration from corrosion or other sources. If you see corrosion or other deterioration, contact your heating contractor for repairs. Check vent damper operation as follows: 1. When the boiler is off, check that the vent damper positions indicator points to the closed position, Fig.

Controls and Accessories — What They Do POP SAFETY VALVE The pop safety valve should open automatically i the boiler steam pressure exceeds the pressure rating of the valve {15 psi. Should it ever fail to open under this condition, shut down your boiler.
For Your Safety Read Before Operas WARNING: if you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. Some boilers are equipped with an intermittent ignition device which automatically fights the pilot. Do not try to light the pilot by hand Some boilers are equipped with a continuous pilot and must be manually lighted. {See lighting instructions on page 18-19.)

Operating Your Boiler HOW A STEAM SYSTEM OPERATES The wale in the boiler is heated until it reaches the boiling point. As the water boils it turns into steam. The steam rises from the top of the water through the supply main fo the radiation units. As it passes through the radiators it releases ita heat and condenses into water. The wale returns to the boiler through the return main, Most residential systems operate at less than 1 pound steam pressure.
eking and Adjusting ADJUST PILOT BURNER Pilot flame should surround 3/8" to 1/2” of the pilot sensor. Refer 10 Fig. 18. if flame needs adjusting, do it as follows: 1. Remove screw cover over pilot adjusting screw. 2. Insert small screwdriver and adjust flame as needed. Turn screw counterclockwise to increase flame, clockwise to decrease. 3. Replace screw cover over pilot adjusting screw, MAIN BURNER(S) The main burners do not require primary air adjustment and are not equipped with primary air shutters.
drop the pressure setting until the boiler shuts down. This will show that the pressure limit is operating properly. Refer to control manufacturer's instructions {enclosed} for more information Check thermostat operation. When set above temperature indicated on the thermometer, boiler should ignite. Make certain the thermostat turns off the boiler when room temperature reaches the selected setting and starts the boiler operating when room temperature falls a few degrees.
Maintaining Your Boiler Chan the water level every day or two. Verify the water fine shown by operating the drain valve on the gauge, BE SURE TOP AND BOTTOM VALVES ON GAUGE ARE ALWAYS OPEN 50 THAT ACTUAL WATER LEVEL WILL BE SHOWN AT ALL TIMES. The gauge glass should be dry above the water line. The water line should not bounce more than about one inch when the boiler is steaming.
You may avoid inconvenience and service calls by checking these points before you call for service. FOR YOUR SAFETY WHAT TO DO IF YOU SMELL GAS 1. Do Not try to light any appliance. 2. Do not touch any electric switch, do not use the phone. 3. Leave the building immediately, then call your gas supplier. 4. if you cannot reach the gas supplier, call the fire department. IF YOUR SYSTEM IS NOT HEATING Possible Cause What to do Thermostat is not set correctly Reset thermostat above room temperature.
