BOILER ROOM REQUIREMENTS A. Room should be well lighted and should have a source of emergency light. B. Convenient water supply available for boiler and to clean the boiler room floor. C. Unobstructed floor drains. D. Since the combustion process requires a supply of air at all times, it is essential that provisions are made to supply adequate air to the boiler room.
Frequently Used Boiler Terms BTU - British Thermal Unit, amount of energy to raise one lb. of water one degree F. 1000 BTU = 1 lb. of steam 150 BTU = 1 sq. ft. of hot water 34.5 lbs. steam/hr. = 1 boiler horsepower 1 Boiler hp = 140 sq.
Items Not Provided That Should be Considered: Pressure Reducing Valve - used to automatically maintain a desired pressure in the system, acts as a make-up water supply. Tempering Valve - allows hot water from boiler to accurately mix with returning cool water to make desired water ready to go to the application. The hot water should be at least 20 degrees warmer than the return water for smooth operation.
COIL INSTALLATION Note the Model L24 can accept just one coil, the Model 60 can utilize one or two. Coil Installation: Model L24: The front cover plate and rubber gasket on the boiler needs removed first. The coil can be inserted in the boiler after the plate is removed. The coil is attached at the rear of the boiler.
Basic Information for a Boiler System Water [properly treated] is the most common fluid used in a closed loop hydronic system. Other Fluids Used in Closed Loop Systems • Glycol (antifreeze) is used in systems where below freezing or above boiling point temperatures may be reached.
Page 23
Expansion Tank • Heating water causes it to expand, thus creating a need for a expansion or overflow tank. • If the expanding water is trapped it will create unsafe pressures. • Tanks should be rated 75 psi or greater. •...
BOILER JACKET PANEL ASSEMBLY INSTRUCTIONS *Model L24 will require that the lower part of cabinet front be snapped off at perforations. 1. Model WL60 and L24, mount burner on boiler swing door. 2. Do not pipe the boiler until cabinet panels are on. 3.
Hot water boilers are subject to serious damage and failure if leaks develop in the hydronic system that requires excessive make-up water. The make-up water introduces high levels of oxygen which will lead to cor- rosion and component or system failure in a very short time. All boilers and systems should be checked for leaks on a frequent basis.

• Another test which is sometimes used as a gauge of solids is to measure the chloride present in the boiler water. The ratio of chlorides in the boiler water to that of the feed water can be used as a means to determine the amount of blow down required.
1. Turn burner power off to prevent accidental burner firing. Remove the front cleanout door(s) and open burner door. The WL-60 door will swing open simply by removing the 3 hex nuts on the handle side of the door. If burner is hard piped, disconnect pipe fittings to allow door to swing freely. The L-24 has a slightly different procedure.

The Model L-24 Boiler has a special swing door assembly for cleaning the fire chamber. Hinge bolt and nut Hinge bolt and nut If burner is hard piped, disconnect pipe fittings to allow door to swing freely. Insure that the burner door is not hot.
should only be used in closed circulating systems without tankless coils. Propylene glycol should be used in boilers that have tankless coils installed. • Antifreeze solutions expand more than water for a given temperature rise. Allowance must be made for this additional expansion when antifreeze solution is used in the heating system.

FIELD ASSEMBLY INSTRUCTIONS - BURNER 1) PRIOR TO INSTALLING BURNER, CHECK FOR SHIPPING DAMAGE TO FLAME RETENTION HEAD AND IGNITION ELECTRODE ALIGNMENT. 2) If components are not as shown you can make adjustments to the electrodes by removing the hole plug on top of burner tube near mount flange. With screw driver, loosen the screw holding the electrode clamping plate.

INSTALLATION OF CHIMNEY SYSTEM INSTALL CHIMNEY TO FLUE COLLAR OF BOILER OR HEATER 1) Select a location for your boiler observing minimum clearance to combustibles. Consider that maintenance and cleaning will be required. Allow adequate work space around burner and stack. 2) For best operation minimize distance of horizontal chimney runs.

COMPRESSED AIR SUPPLY 1. A minimum 2 CFM at 40 psi is needed into the B-5 single burner and 4-5 CFM @ 40 psi for the B-10 double burner. Use a hydraulic quick disconnect or put ample flex in the line to swing burner open when servicing.
Suction Line: Field provides piping from Check Valve to Filter. Secure piping to keep the Suction Strainer 6 inches off the bottom of the tank in order to avoid water and antifreeze pickup from the bottom of the oil tank. Plan ahead for routine service of components.
INITIAL START UP AND OPERATING SEQUENCE 1. Check secondary air settings as described in section #3 on page 41. Place the 3-position toggle switch on the Burner to “OFF.” Energize the boiler circuit with electricity. The amber and red lights on the slide gun will come on.

FINE TUNING THE BURNER OBSERVE THE FLAME DAILY. ALLOWING BOILER TO OVER FIRE WILL DESTROY THE HEAT EXCHANGER AND VOID THE WARRANTY. UNDERFIRING MAY LEAD TO CONDENSA- TION AND RUST THE CHIMNEY OR BOILER. Due to variations in used oils, the air and oil pressure gauge setting are approximate. Final adjustments need to be made with your specific fuel.
PRIMARY CONTROL FUNCTION - SAFETY LOCKOUT CAUTION: DO NOT RETRY IGNITION MANUALLY IF THE BURNER FAILS AND THE BOILER IS HOT! FORCING A REFIRE AT THIS TIME CAN PUT FUEL INTO THE HOT COMBUSTION CHAMBER AND CAUSE AN EXPLOSION HAZARD. THE CONTROL WILL AUTOMATICALLY ATTEMPT TO RESTART AFTER 45-60 SECONDS IF THE CAD CELL DETECTS A FLAME INITIALLY.
Page 44
CAUTION: Used oil may contain heavy metal compounds and foreign materials. When burned, the compounds are deposited in the boiler and chimney. Protective clothing, including gloves, face mask, and respirator must be worn when cleaning is done. All waste materials removed when cleaning the system should be stored in a closed noncombustible container until properly disposed.

Assembly of Nozzle O-RING 57186 FERRULE DISTRIBUTOR For a more thorough service the following burner components can be cleaned as a preventative yearly maintenance.
Page 47
ALUMINUM PREHEAT BLOCK For a more thorough service the aluminum preheat block can be cleaned. The need to increase oil pressures to maintain a good flame is a indicator block passages may be restricted. How quickly a block becomes restricted varies with hours of use and oil quality. Block cleaning is a skilled service that inexperienced persons should not undertake.
END OF HEATING SEASON/SUMMER STORAGE 1. Turn off power to boiler and set aquastat or thermostat to “off.” 2. Clean boiler and chimney thoroughly. See previous sections for details. 3. Spray interior of combustion chamber with light oil to protect against corrosion. 4.
Page 51
7. Check for condensation in compressed air line. Air solenoid could be sticking or air proving switch stuck in open position. This would keep power from igniter, burner motor, and oil valve. Indicator would be green light does not come on. Fluttering Or Pulsating Flame 1.
Poor Draft 1. Confirm there is -.04 to -.06 inches water column at breech of exchanger. 2. Firebox, flue outlet, or stack is plugged with ash. 3. Exhaust fan in building reverses draft in chimney. 4. Cold building at night creates down draft in chimney. 5.
