Caution
On hot water systems, expansion tank should not be installed in cold or exposed place. No valves of any type should be installed in piping between boiler and expansion tank. Sealing system at any time during operation may cause breakage of boiler or radiators.
"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
If water condition is encountered in basement, or if it has been neces sary to water-proof the basement floor, boiler should be mounted on concrete or hollow tile base at least 3 inches above floor level. Assembly of Sections
1. All reference to right or left refer to observer's right or left when facing front of boiler where manifold is attached.
2. Select right end section and place on block on floor, as shown in Fig. 1. Clean nipples and nipple openings with kerosene or gasoline and apply good lubricating oil. Do not use paint or red lead.
3. Drive nipples squarely into section, using block of wood and hammer. Each nipple must project outside of finished
than half its length. Use rule or gage to insure that nipples project outside of opening equally all around. Most nipple leaks are caused by tilted or cocked nipples.
4. Paint ground rib, around

and support with suitable blocking. Sections should stand approxi
mately in their final position with Front facing correctly. (Note--Flow
tapping is toward rear of end section.)
7. Insert tie rods through lower nipple openings and tappings on end section and through cored hole below upper nipple port.
Place assembling blocks on lower rods across nipple ports as shown on Fig. 2 placing nuts an<l washers on all rods. Draw up evenly on nuts until sections make contact at ground joints. Bumping sections with heavy block of wood alternately at nipple ports during drawing up operation will facilitate assembly.
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 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 to insure against breakage from handling and shipping. To safeguard accuracy of gage supplied with boiler do not install gage until after test of boiler. This precaution of testing the boiler will simplify handling of any necessary replacements or adjustments and assist in treating with claims against transportation companies. After test, drain and remove plugs where required.
Assembly of Platework

Pilot Goes Out If the pilot flame is extinguished, the automatic pilot will shut off the
automatic gas valve. If boiler is not operating correctly, call Heating Contractor or Gas Company service man. If boiler is operating cor rectly, relight as directed above.
Operation During Failure of Electric Power Supply In of failure of supply of electric current, boiler will automati
cally shut off. Boiler will not operate automatically while electric power is off, however, boilers equipped with Detroit 569-VS (or VW) auto matic gas valve may be operated manually as follows:
1. If pilots are out, relight as directed for manual ignition. 2. When pilots are lighted, press down on manual control lever on automatic gas valve; main burners should light; press in hand resetting button to hold lever down, burners will remain lighted. 3. Caution--Shut off boiler before water temperature or pressure becomes excessive by pressing down on manual control lever until reset button is released, then release manual control lever. Bear in mind that operating the boiler manually is an emergency condition and that constant supervision is required to prevent the pos sibility of damage due to overheating. Never allow the boiler to operate under this emergency condition if it is to be left unsupervised for any length of time. 4. Valve is fully recycling and will return to automatic operation when electric power returns.

CARE AND ATTENTION
In Fall before Starting Boiler 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.
Care 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
Fill system as during heating season. Have boiler inspected by serv ice man before the start of the heating season. If necessary, remove front jacket and cleanout cover plates and clean heating element.
26871

General Care 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.
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. (See Caution.)
5. Fill hot water systems as follows: Open all radiator valves, but keep vents at top of radia
tor 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, begin ning 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. Never place valves in piping leading to or from expansion tank.
