GENERAL The Custom Mark III CP Series Oil Fired Unit is a high quality heating unit that will provide many years of comfortable and economical heat if properly installed and given proper care. It is IMPORTANT therefore that these instructions should be followed carefully. SHIPMENT The unit is completely assembled at the factory except for the following parts which are packed in a separate carton and strapped to the skids inside the shipping carton:
The jacket extension for 128CPO is shipped in separate carton. DAMAGE IN TRANSIT Upon receipt of shipment of this material, inspect all cartons for external damage. If external damage is noted, open the carton and inspect for damage to equipment. Mark the number of cartons received in this condition on the delivering carrier's waybill, and request the services of their inspector. If, upon opening a carton, concealed damage is discovered, open the entire shipment and note all equipment so damaged. Contact the delivering carrier and request inspection of the damaged equipment. Do not destroy the carton. The inspector from the freight company will need this to determine reason for damage. Normally claims for any and all damages should be filed with the freight company within five working days after receipt of shipment. All materials are sold F.O.B. Factory. It is the responsibility of the consignee to file claim with the delivering carrier for material received in a damaged condition. LOCATING UNIT BEFORE REMOVING SHIPPING CARTON, LOCATE UNIT IN ITS FINAL POSITION The carton is plainly marked so as to indicate which is the outlet burner end of the unit which is also the end where the return and flue are located. Clearance should be provided in both the front and rear of the unit for cleaning. Where possible it is good practice to locate the REMOVING CARTON Once the packaged unit is in its proper place, cut all around the carton on the scored line as shown on carton. The entire carton may then be lifted from the skids. If it is found necessary to move the unit a little more to place it in the exact location ready for piping, do so before removing skids. DO NOT PUSH AGAINST ANY PART OF JACKET OR OIL BURNER WHEN MOVING UNIT. TO MOVE UNIT, PUSH AGAINST SKIDS, FLUE BOX OR SMOKE BOX. PUSHING AGAINST JACKET WILL RESULT IN DAMAGE. REMOVING SKIDS The skids are specially designed for easy removal. It is necessary, however, to follow these instructions carefully.
IMPORTANT LEVELING UNIT In case floor is uneven, unit may easily be made level by inserting shims under the 4 shipping lugs. These lugs also keep the jacket 1/2" off the floor, protecting it from wet floors and dampness. PIPING AND WIRING Once the unit is in its proper location with the packing carton, skids and packing material removed, it is ready for piping and connection from Room Thermostat and 110 V. 60 Cy. A.C. Current. CONTROL SYSTEM The controls furnished are for a one zone Forced Water System consisting of T87F Room Thermostat, L8124A-1007 Triple Acting Aquastat and Circulator Relay, SPECIAL CONTROL SYSTEMS For special control systems such as multiple installations, zone controlled, unit heater, radiant panel, etc., write to factory for wiring diagrams. CHIMNEY AND BREECHING REQUIREMENTS The CP boiler should be connected to a vertical vent system that will prevent: (1) positive pressure in the flue, (2) backward flow of flue gas through the unit when the burner stops, and (3) condensation in the flue. Use double-walled or insulated pipe for sections of the flue in cold areas. All outside vents, except for short extensions, must be insulated to avoid condensation in the flue. Several types of prefabricated chimneys are available providing double-walled or insulated pipe, some with ceramic and others with metallic liners. While the unit is equipped with an induced draft fan, proper size vent must be provided to remove the gases of combustion. It is recommended that a 4" to 5" increaser be used for venting the 87CPO and 108CPO and a 4" to 6" increaser be used for the 128CPO. For abnormal runs (exceeding 10 ft.), consult factory. Vent and breeching must be gas tight by sealing with asbestos or thermo-setting pressure sensitive tape. DRAFT REGULATOR It is recommended that a draft regulator be installed in chimney flue just below the flue pipe opening, if the unit is attached to an extremely high chimney; an unlined chimney; or a chimney which is constructed on the exterior of the house. CONTROLS AND TRIM Controls are installed in place at the Factory. Attach thermo-altimeter in 1/2" tapping in top front of boiler. Install 3/4" × close nipple in 3/4" top connection with 3/4" × 3/4" × 1/2" Tee. 3/4" Tee opening for installation of the relief valve and 1/2" opening for expansion tank. WIRING Controls are all in place and wired at the factory except connection to circulator. REGULATING OIL PRESSURE Standard nozzles furnished with the burner will produce the stamped rated capacity when used with Commercial Standard No. 2 Fuel Oil, and operated with a pressure of 100 lbs. per square inch. The standard setting of the fuel unit is 100 lbs. Due to difference in tank elevations, the pressure should be adjusted at the time of start up. FUEL LINES Care should be employed when attaching the oil lines to the fuel unit. Overtightening or twisting will twist the pump-motor mounting plate and put a stress on the motor bearings. START UP PROCEDURE General:
ADJUSTING BURNER (See Figure 1) Positioning of the nozzle in relation to the face of the cone and the electrodes in relation to the nozzle are very important, also the face of the cone in relation to the face of the choke ring must be set according to the chart for each rate. If the air shutter openings are too large the oil may not ignite.
NOTE A. CHECK LIMIT CONTROL
NOTE BELT ADJUSTMENT The proper tension on the fuel unit belt drive is set at the factory. However, the belt should be checked periodically to see that the setting is maintained. To check setting, first, remove the belt guard and then, using fingers, compress the belt at a point midway between the sheaves. The proper setting at this point measured between the outer edges of the belt, should be between 1-3/4" and 1-7/8". If adjustment is necessary loosen the two mounting bolts, and move the fuel unit up or down to give the necessary belt setting. Then re-tighten the mounting bolts securely and replace the belt guard. PERFORMANCE CHECK LIST QUESTION: What Causes Unit To Soot Up? Answers: DOMESTIC HOT WATER In order to obtain the rated capacity of the instantaneous domestic hot water coil limit control should be set to maintain 200° F boiler water temperature. Flow regulator and tempering valve should be installed on all instantaneous domestic hot water coil systems. BURNER SETTING The burner is adjusted at the factory before shipment but in case of improper operation at some future date Figure 1 will show proper setting. In all cases the flame retention ring should be concentric with the choke. FIGURE 1
