266 thru 566 forced hot water boilers or any size steam boiler. 1. Locate tank as high as possible above boiler. 2. Vertical type storage tank can be used if bottom of tank can be located above top of boiler. 3. To provide gravity circulation: a) Horizontal supply from heater to tank must pitch upward 1 inch for each 10 feet of piping. b) Horizontal return from tank to heater must pitch downward 1 inch for each 10 feet of piping. 4. Locate return piping above storage heater. 5. Use as few elbows and pipe fittings as possible.

Use a low water cut-off designed for water installations. An electrode probe type is recommended. Locate in a tee in supply line above boiler. 4. If the system is to comply with ASME codes, an additional high temperature limit is needed. Purchase and install in supply piping from boiler. LEFT SIDE ^ 15" minimum heater clearance.

WATER BOILER CONTROLS (non-packaged boilers) 1. Install controls where shown on tapping table. 2. STEAM BOILER CONTROLS (non-packaged boilers) 1. Connect a low water cut-off to gauge glass tappings K1 and K2. Refer to Figure 11. Follow instructions packed with the control. Pipe drain near the floor or floor drain. 2. Install the pigtail syphon, pressure gauge and steam pressure limit control.

Do not pipe where freezing could occur. 3. Low water cut off for water boilers: a) Should be installed if boiler is located above radiation level. b) May be required on water boilers by certain state, local or territorial codes or insurance companies.

INSTALL OIL BURNER (non-packaged boilers) For B-66HE boiler: 1. Place gasket over end of air tube. 2. Loosely screw three mounting bolts into boiler mounting plate. 3. Mount burner. 4. Tighten mounting bolts. For A-66E boiler (see Figure 12): 1. Secure universal mounting flange and gasket to burner mounting plate. Use three bolts provided. 2. Position burner so it is level to l1^0 tilt downward. Air tube should be flush to 1k inch recessed from inside wall of combustion chamber. 3. Clamp mounting flange to burner using screws provided.

Use a Class A chimney. Minimum chimney or vent sizes are on page 12 of these instructions. In most cases a chimney or vent extended at least 3 feet above the highest part of the roof or other structure within 30 feet will be sufficient to prevent downdrafts. Increase chimney cross-sectional area and height at least 4 percent for each 1,000 feet above sea level. Examine the chimney for proper construction and possible blockage. An induced draft fan may be necessary if: 1) Excessive resistance to flow of combustion gases can be expected. 2) Cross-section area of chimney is smal...
