INSTALLATION AND OPERATING INSTRUCTIONS
CUSTOM MARK III
CP SERIES OIL FIRED UNIT

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:

- 1 - 3/4" × Close Steel Nipple
- 1 - 3/4" × 3/4" × 1/2" Tee
- 1 - Fig. 105 Tridicator
- 1 - 3/4" No. 10-402-05 ASME Relief Valve
- 1 - 3/4" No. 600-19 Boiler Drain
- 1 - T87F-2055 Thermostat

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 unit so its sides are parallel to the chimney flue. In all instances locate unit as near chimney flue as possible in order to avoid use of a long flue pipe.

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.

1. After unit is in proper place, remove the two cross pieces from skids by pulling out all scaffolding (double headed) nails.

2. By inserting pinch bar or 2" × 4" underneath the smoke box (rear of unit), tilt one side of unit just high enough to lift lugs out of holes in skid, then knock skid out from underneath unit. Then do the same thing on the other side of unit. THE UNIT IS NOT BOLTED TO THE SKIDS. The 3/4" lugs welded to the unit simply fit into the 3/4" holes in the skids.

IMPORTANT

DO NOT TILT UNIT BY PUSHING AGAINST JACKET

IT IS NOT NECESSARY

AND BY DOING SO THE JACKET WILL BE DAMAGED

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, C554A-1018 Cadmium Photocell, R8184G-1005 Burner Relay and V4046A-1009 Oil Valve. Description and complete wiring diagram will be found packed with each control.

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:

1. Make certain that correct voltage has been supplied to motor and control circuit.

2. Insure that outside air openings are provided in the boiler room for ventilation, and for admission of air for combustion. The free area of such openings should not be less than 7 square inch opening per 100,000 Btuh burner input, or more as required by local codes.

3. Check to see that flue, wiring and water level are in order.

4. Start burner fan motor to prime pump. If pump does not pick up oil within a few minutes, prime the pump with lubricating oil. Do not allow pump to run more than a few minutes without additional lubrication.

5. Check oil pressure and adjust if necessary. (See REGULATING OIL PRESSURE).

6. Set air shutters. (See ADJUSTING BURNER) Refer to Figure 1.

7. Generously lubricate the front motor bearing with SAE #20 oil.

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.

1. This setting will vary somewhat depending upon the grade of oil being used or if No. 1 is used instead of No. 2.

2. The approximate burner air setting may be determined by observing the fire through the observation port on the front of the boiler. If the flame is smoky, the air shutter should be opened until the fire burns clean, without any trace of smoke. The flame should be bright yellow in color with the tips of the flame turning orange. If the flame is too white, reduce the amount of air admitted; and, if too red or smoky increase the air.

3. Final adjustments should be made using a flue gas analyzer to measure the CO_2 content of the flue gas and a Bacharach model smoke meter or equivalent to determine the amount of smoke (not to exceed a "TRACE").

4. For checking efficiency only the stack temperature and CO_2 may be taken immediately after the fan and refer to the standard efficiency charts for the results. Readings of 5 to 8% taken after the fan correspond to 10 to 12% taken in the rear uptake of the boiler.

5. The reduction in CO_2 reading in the flue is caused by the air being drawn in around the motor shaft for cooling purposes. The motor cooling air is at ambient temperature and, therefore, does not add energy to or subtract energy from the flue gas analysis, it only adds volume to the flue gas. Therefore, applying this data to standard efficiency charts will give a true indication of flue gas loss.

NOTE

Final adjustment should be made after the burner has been firing continuously for at least 10 minutes, as the fan pulls less air when the flue gases are hot.

A. CHECK LIMIT CONTROL

- Run the burner long enough to bring the water temperature up to at least 190 degrees then turn the limit control setting until the burner stops.

NOTE

The Minimum limit setting for any hot water boiler should be 140 degrees F. in order to prevent corrosion of the flues on the fire side. The burner should be run with the primary control thermostat terminals jumpered and the burner controlled directly from an aquastat keeping the boiler hot all the time, thus eliminating the sweating of the flues on the fire side caused by starting from a cold start.

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.

Section 2. Information about the Mission of Project Gutenberg

Project Gutenberg is synonymous with the free distribution of electronic works in formats readable by the widest variety of computers including obsolete, old, middle-aged and new computers. It exists because of the efforts of hundreds of volunteers and donations from people in all walks of life.

Volunteers and financial support to provide volunteers with the assistance they need are critical to reaching Project Gutenberg’s goals and ensuring that the Project Gutenberg collection will remain freely available for generations to come. In 2001, the Project Gutenberg Literary Archive Foundation was created to provide a secure and permanent future for Project Gutenberg and future generations. To learn more about the Project Gutenberg Literary Archive Foundation and how your efforts and donations can help, see Sections 3 and 4 and the Foundation information page at www.gutenberg.org.

Section 3. Information about the Project Gutenberg Literary Archive Foundation

The Project Gutenberg Literary Archive Foundation is a non-profit 501(c)(3) educational corporation organized under the laws of the state of Mississippi and granted tax exempt status by the Internal Revenue Service. The Foundation’s EIN or federal tax identification number is 64-6221541. Contributions to the Project Gutenberg Literary Archive Foundation are tax deductible to the full extent permitted by U.S. federal laws and your state’s laws.

The Foundation’s business office is located at 41 Watchung Plaza #516, Montclair NJ 07042, USA, +1 (862) 621-9288. Email contact links and up to date contact information can be found at the Foundation’s website and official page at www.gutenberg.org/contact

Section 4. Information about Donations to the Project Gutenberg Literary Archive Foundation

Project Gutenberg™ depends upon and cannot survive without widespread public support and donations to carry out its mission of increasing the number of public domain and licensed works that can be freely distributed in machine-readable form accessible by the widest array of equipment including outdated equipment. Many small donations ($1 to $5,000) are particularly important to maintaining tax exempt status with the IRS.

The Foundation is committed to complying with the laws regulating charities and charitable donations in all 50 states of the United States. Compliance requirements are not uniform and it takes a considerable effort, much paperwork and many fees to meet and keep up with these requirements. We do not solicit donations in locations where we have not received written confirmation of compliance. To SEND DONATIONS or determine the status of compliance for any particular state visit www.gutenberg.org/donate.

While we cannot and do not solicit contributions from states where we have not met the solicitation requirements, we know of no prohibition against accepting unsolicited donations from donors in such states who approach us with offers to donate.

International donations are gratefully accepted, but we cannot make any statements concerning tax treatment of donations received from outside the United States. U.S. laws alone swamp our small staff.

Please check the Project Gutenberg web pages for current donation methods and addresses. Donations are accepted in a number of other ways including checks, online payments and credit card donations. To donate, please visit: www.gutenberg.org/donate.

Section 5. General Information About Project Gutenberg electronic works

Professor Michael S. Hart was the originator of the Project Gutenberg concept of a library of electronic works that could be freely shared with anyone. For forty years, he produced and distributed Project Gutenberg eBooks with only a loose network of volunteer support.

Project Gutenberg eBooks are often created from several printed editions, all of which are confirmed as not protected by copyright in the U.S. unless a copyright notice is included. Thus, we do not necessarily keep eBooks in compliance with any particular paper edition.

Most people start at our website which has the main PG search facility: www.gutenberg.org.

This website includes information about Project Gutenberg, including how to make donations to the Project Gutenberg Literary Archive Foundation, how to help produce our new eBooks, and how to subscribe to our email newsletter to hear about new eBooks.
