If the pipe leading to or from the tank freezes, serious damage may result. If valve of any description is installed in the piping leading to or from the expansion tank BE SURE THAT IT IS OPEN WHILE THE BOILER IS IN OPERATION. "This appliance should be installed in accordance with the latest AGA Instructions For Installation of Gas Piping and Gas Appliances in Buildings. Reference should also be made to gas company regulations and local building, plumbing or other codes in effect in the area in which the installation is made." Location. Locate the boiler near the chimney or flue and as centralized with respect to the heat distribution system as practicable. If water condition exists in the basement, or if it has been necessary to water proof the basement floor, the boiler should be mounted on a concrete or hollow tile base, preferably to a height of at least three inches. In utility room installations, the door shall be wide enough to allow the largest boiler part to enter or to permit the replacement of another appliance such as a gas water heater. Air for Combustion and Ventilation Adequate facilities must be available for providing air for combustion and ventilation. Except for installations in large spaces (such as full basements) where infiltration can normally be assumed to provide sufficient air, this will usually necessitate: (a) Two openings, one near the floor, the other near the ceiling, installed in the door or a single wall of the heater room. (b) Opening to interior space, minimum free area of one (1) square inch per (1000) Btu per hour of input rating. (This method should always be used where practicable.) (c) Opening to outdoors, minimum free area of one (1) square inch per (2500) to (3000) Btu per hour of input rating. (This method should only be used where openings to interior spaces are impracticable.) Chimney 1. Flue or vent connector to chimney must be the spine size as the outlet of the draft diverter. (2.) Where two or more appliances vent into a common flue, the afea of the W common flue should at least equal the area of the largest flue of vent L connector plus 50 per cent of the areas of the additional flue or vent s connectors. 3. Flue or vent connector must be inserted into but not beyond the inside wall of the chimney flue. L 19050 G-4 GAS BOILER Pipe Delivery Schedule Capacity of Pipes in Cubic Feet of Gas per Hour.

Place sections in upright position and support with suitable blocking. Sections should stand approximately in their final position with Front facing correctly. See Fig. 3 (Note Cleanout open ings are at front of boiler). Fig. 3--Assembling Sections 7. Insert tie rods through lower nipple openings and tappings on end section and through cored hole below upper nipple port. Place 3" C.I. washers on lower rods against tappings. Place assembling blocks on lower rods across nipple ports as shown on Fig. 3 placing nuts and washers on all rods. Draw up evenly on all tie rods, starting with lower tie rods. Tighten nuts alternately and bump sections with heavy block of wood at nipple ports to facilitate assembly. Continue to draw up alternately until sections make contact at ground 19052 ) G-4 GAS BOILER 5 joints. Apply oil or grease freely to tie rod threads while assembling sections to prevent stripping of threads on rods. Paint ground ribs of each section with red lead and continue assem bling center sections one at a time. Shift blocking each time so that support is under the last section assembled. 8. Remove tie rods and place Left End in position. Insert lower tie rods through lugs on ends and upper tie rod through hole in sections. Draw sections together as in previous operations until ground joints are tight. Back off all tie rod nuts until they are finger tight only, to allow for expansion. Testing Before connecting boiler, plug openings, fill boiler with water and subject to not less than 10 lbs. nor more than 30 lbs. pressure. Inspect boiler inside and outside for leakage as a result of breakage from handling and shipping. To safeguard accuracy of gage and controls supplied with boiler, do not install until after test of boiler. This pre caution of testing the boiler will simplify handling of any necessary re placements or adjustments and assist in treating with claims against transportation companies. After test, drain and remove plugs where re quired. Assembly of Platework, Main Burners and Manifold 1. Screw short threaded end of brass studs into tapped bosses in recess between sections and attach cleanout cover plates to front of boiler. Putty openings between plates and sections.

Fig. 17 shows front view of complete water boiler. (6 sections). Filling System CAUTION: Never start boiler unless it is properly filled. (After boiler is in operation make up water should be added slowly). Steam boilers should be filled until water is visible midway up gage glass between try cocks. Fill open hot water system to V3 height of expansion tank, remove rim and glass from gage and set movable pointer under automatic pointer. Replace rim and glass. Fill closed hot water systems until relief valve opens. This should be at a pressure not greater than 30 lbs. per square inch. If necessary adjust relief valve setting. Remove the rim and glass from the gauge and set the movable pointer at a point which will represent an altitude slightly higher than the highest point in the heating system. (An alti tude of approximately 69 feet represents a pressure of 30 lbs. per sq. in.) Note that the altitude-temperature gauge is calibrated both in feet of altitude and in lbs. per sq. in. Replace rim and glass and reduce pres sure by draining out water until the indicating pointer lines up with the movable pointer. Keep system filled. Pointers on gauge should be even. If pressure exceeds 30 lbs. relieve at once by opening relief valve or drain cock. Pilot Adjustment Light boiler as directed in operating instructions and check for gas leaks. Adjust pilot flame to extend over top of burner. Pilot rate can be adjusted with screw underneath cap on pilot throttling cock. 19064 3 G-4 GAS BOILER 17 Normal Pilot Input for Baso Pilot Burners Input per Pilot Burner Btu/Hr. Mfd. 1000 Gas Nat.

SAFETY DEPENDS UPON THE CARE AND JUDGMENT EXERCISED BY THE OPERATOR. ALL POSSIBILITIES CANNOT BE COVERED IN THESE BRIEF DIRECTIONS. BASIC STEPS IN MANUAL OPERATION 1. Be sure the burner pilot it burning properly. If io, then: - 2. Turn off electric power switch controlling the burner. LEAVE THIS SWITCH OFF UNTIL POWER HAS BEEN RESTORED. 3. Burner may now be operated manually by opening the automatic gat control valve in accordance with instructions printed on the valve cover. .4 If the boiler operated by the gas burner is installed on a forced circulation hot water heating system (incorporating electric circulating pump) OPEN FLOW CON TROL VALVE OR VALVES IF PROVIDED IN THE WATER LINES. (Mote: It is suggested that the original position of these valves be carefully observed and these observations recorded, to permit restoring these valves to their original posi tion when automatic operation is resumed.) Also, REDUCE THE MAIN BURNER FLAME TO A MINIMUM ADJUSTMENT (approximately 1/3 or 1/4 normal size) BY PARTIALLY CLOSING THE MANUAL GAS SHUT OFF VALVE. TO RESTORE BURNER TO AUTOMATIC OPERATION UPON RESUMPTION OF SUPPLY OF ELECTRIC CURRENT 1. Return automatic gas control valve to its original `'automatic" setting, in accordance with instructions on valve cover. 2. Turn on electric power supply switch. 3. On forced circulation hot water heating systems, return flow control valves, if pro vided, to their normal operating positions. .4 Turn manual gas shut off valve to its wide open position. 19071 Drain system sufficiently to remove sludge in bottom of boiler. Do not drain more water than necessary to remove sludge. Then refill to proper level as directed above. Maintenance of Boiler While in Operation 1. Check water level regularly and add water slowly when needed. 2. This boiler is fired automatically. 3. Test safety valve on steam boiler at beginning of season and once a month thereafter: a) Fasten cord or wire to valve lever. b) When pressure is up, stand safe distance away and pull cord. (Steam should be released). In Winter While Not in Operation Drain entire system to prevent damage from freezing. Drain through drain cock, located at lowest point in system. Be sure boiler is com pletely drained. In Summer While Not in Operation Keep the system filled as during the heating season. Each boiler should have a periodic check up of all safety controls and a close inspec tion of the burners, mixing tubes, flue passageways, draft hoods and flue pipe. It is also good practice to recheck the input firing rate and the gas air mixture on the burners to see that the boiler is operating at normal efficiency. This inspection should be made by your heating contractor or a competent service man before the start of each heating season. If necessary, remove the cleanout jacket panel and the cleanout cover plates and clean pin fin surfaces of the boiler sections. The above inspection should include the testing of all safety pilots, limit controls, safety relief valves, and low water cutoff on steam boilers. General Maintenance of Heating System 1. Keep radiators and convectors clean. 2. Keep system in good repair. It is advisable to have it inspected by your heating contractor at least once a year. 19072 G-4 GAS BOILER 25 3. If a hot water radiator is hot at the bottom but not at the top, it indicates that air has accumulated inside and should be vented. To vent radiator: Hold small cup under air vent (Located near top of radiator), open vent until water escapes and then close. 4. Fill steam boilers only as directed (on page 16.) See CAUTION Note. 5. Fill hot water system as follows: Open all radiator valves, but keep vents at top of radiator closed. Fill open systems till hands on altitude gage are even. If it is a closed system the water filling will stop automatically when proper pressure is reached. (Pressure should not exceed 30 pounds). Then, beginning with ground floor, vent each radiator as directed above. It may be necessary to add water during this operation to expel air from higher radiators. 6. If much water is added to system, it is advisable to heat system to a high temperature and vent again. This will make less venting neces sary during the winter. 7. Where an expansion tank is used, make sure that neither the tank nor its drain pipe is exposed to freezing temperatures. See caution note on page 2. CLEANING BOILERS The grease used to lubricate the cutting tools during erection of new piping systems serves as a carrier for dirt, with the result that a scum of fine particles and grease accumulates on the surface of the water in all new boilers, while heavier particles may settle to tire bottom of the boiler and form sludge. These impurities tend to cause foaming, preventing the gen eration of steam and causing an unsteady water line. This unavoidable accumulation of oil and grease should be removed by blowing-off the boiler as follows: If not already provided, install a surface blow connection of at least 1V inch nominal pipe size with outlet extended to within 18 inches of the floor or to sewer, inserting a valve in line close to boiler. Bring the water line to center of outlet, raise steam pressure, and 19073 26 G-4 GAS BOILER while burners are operating open valve in blow-off line. When pressure recedes, close valve and repeat process adding water at intervals to maintain proper level. As a final operation bring the pressure in the boiler to about 10 lbs., close blow-off and manual shut-off valves, then open drain valve. After boiler has cooled, partly fill and flush out several times before filling it to proper water level for normal service. The use of soda or any alkali, vinegar or any acid is not recommended for cleaning heating boilers because of the difficulty of complete removal and the possibility of subsequent injury after the cleaning process has been completed. SUGGESTED PIPING ARRANGEMENT FOR BLOWING-OFF STEAM BOILERS Caution After the blow off operation, a checkup should be made of the Low Water Cutoff as directed on Page 17. 19074 G-4 GAS BOILER 27 Note: All parts of this boiler have been carefully inspected and packed. See Packing and Parts List sheet for details. In case of shortage, make sure that all parts have been removed from shipping container and examine packing material thoroughly.
