OUTDOOR INST ALLA TIONS Raypak Hi Delta Boilers are design certified for outdoor installation. Boilers must not be installed under an overhang that is less than three (3) feet from the top of the boiler . Three (3) sides must be open in the area under the overhang.
SECTION C: COMBUSTION AND VENTILA TION AIR COMBUSTION AND VENTILA TION AIR (Indoor Units) The boiler must be supplied with sufficient quantities of non-contaminated air to support proper combustion and equipment ventilation.
COMBUSTION AND VENTILA TION AIR SUPPL Y (FOR CANADA INST ALLA TION) CAUTION: All combustion air has to be drawn from the air outside the building (the mechanical equipment room directly communicates with the outdoors).
SECTION D: W A TER PIPING - GENERAL The boiler should be located so that any water leaks will not cause damage to the adjacent area or structures. CAUTION: This boiler r equires for ced water cir culation when the burner is operating. See T able D-1 for minimum and maximum flow rates and water pump selection.
SECTION E: HYDRONIC HEA TING PIPING PUMP SELECTION In order to insure proper performance of your boiler system, you must install a properly sized pump. Raypak recommends using a 20°F Delta T as design Delta T . (Delta T is the temperature difference between the inlet and outlet water when the boiler is firing at full rate).

SECTION F: DOMESTIC HOT W A TER PIPING When designing the water piping system for domestic water applications, water hardness should be considered. T able F-1 indicates the suggested flow rates for soft, medium and hard water . Hardness is specified as grains per gallon.
SECTION G: POOL HEA TING CAUTIO CAUTION: Power to the heater should be interlocked with the main system pump to make sure the heater does not fire without the main system pump in operation. Improper flow control can damage the heater . Uncontrolled flow (too high) or restricted flow (too low) can seriously damage the heater .
A UTOMA TIC CHLORINA TORS AND CHEMICAL FEEDERS All chemicals must be introduced and completely diluted into the pool or spa water before being circulated through the heater . Do not place chlorine tablets or bromine sticks in the skimmer . High chemical concentrations will result when the pump is not running (i.
SECTION H: GAS SUPPL Y CONNECTIONS DANGER: Make sure the gas on which the boiler will operate is the same type as specified on the boiler model and rating plate. Gas piping must have a sediment trap ahead of the boiler gas controls, and a manual shut-off valve located outside the heater jacket.
GAS PRESSURE REGULA T O R The gas valve pressure regulator(s) on the boiler are nominally preset at 3.5" W .C. for Natural gas, and 10.5" W .C. for Propane gas manifold pressure. The pressure at the gas valve outlet tap, measured with a manometer ,while in operation should be 3.
CIRCUIT BREAKER WHITE GROUND BLACK GREEN AB C VOL T-OHM METER SECTION I: ELECTRICAL POWER CONNECTIONS Installations must follow these codes: · National Electrical Code and any other national, state, provincial or local codes or regulations having jurisdiction.
MAKING THE ELECTRICAL CONNECTIONS Refer to Fig. #9227 W iring Connection, and Fig. #9233 or Fig. #9234 W iring Diagram. 1 . V erify circuit breaker is properly sized by referring to boiler rating plate. A dedicated circuit breaker should be provided. 2 .
ELECTRICAL CONNECTIONS - DOMESTIC HOT W A TER CAUTION: Label all wir es prior to disconnection when servicing controls. W iring errors can cause impr oper and danger ous operation.
SECTION J: VENTING CONNECTIONS GENERAL CAUTION: Proper installation of flue exhaust venting is critical for the safe and efficient operation of the boiler . Definition of Appliance Categories Boilers are divided into four categories based on the pressure produced in the exhaust and the likelihood of condensate production in the vent.
Category Determination for Venting Purpose and Venting Arrangement 25 TABLE J-1 * As defined in the latest edition of the National Fuel Gas Code, or in Canada, the latest edition of the CAN/CGA B149.
Support of V ent S tack The weight of the vent stack or chimney must not rest on the boiler vent connection. Support must be provided in compliance with applicable codes. The vent should also be supported to maintain proper clearances from combustible materials.
V enting Installation T ips Support piping: · horizontal runs- at least every five (5) feet. · vertical runs - use braces: · under or near elbows Follow items listed below to avoid personal injury or property damage. · Cut nonmetallic intake pipe with fine-toothed hacksaw (34 teeth per inch).

• Natural Draft V ertical V enting System Installation Natural draft venting uses the natural buoyancy of the heated flue products to create a thermal driving head that expels the exhaust gases from the flue. The negative draft must be within the range of -.
Common venting systems may be too large when an existing unit is removed. At the time of removal of an existing appliance, the following steps must be followed with each appliance remaining connected to the common venting system placed in operation, while the other appliances remaining connected to the common venting system are not in operation.
SECTION J-2 Horizontal Thru-W all V enting (Category III) Fig. #9229.1 HORIZONT AL THRU-W ALL VENTING (CA TEGOR Y III) T ABLE • Horizontal Thru-wall V enting System (Category III) Installation These installations utilize the boiler-mounted blower to vent the combustion products to the outdoors.
The total length of the horizontal thru-wall exhaust vent system should not exceed seventy (70) feet in length. If horizontal run exceeds 70 feet, an appropriately sized extractor must be used. T o maintain proper operation pressure reading must be between -.
• Horizontal Thru-wall Direct V ent T ermination The flue exhaust direct vent cap MUST be mounted on the exterior of the building. The direct vent cap cannot be installed in a well or below grade.

SECTION Q: MAINTENANCE SUGGESTED MINIMUM MAINTENANCE SCHEDULE: Regular service by a qualified service agency and maintenance must be performed to assure maximum boiler operating ef ficiency . Maintenance as outlined below may be performed by the owner .
PREVENTIVE MAINTENANCE SCHEDULE Required procedure in CSD-1 States and good practice for all Hi-Delta installations. Daily 1 . Check gages, monitors and indicators. (See page 6 of the Operating and Installation Instructions Manual). 2 . Check instrument and equipment settings.
APPENDIX A INSIDE COMBUSTION AIR CONT AMINA TION: All boilers experience some condensation during start-up. The condensate from flue gas is slightly acidic. In most cases the pH level is not harmful to vents or drains. When combustion air is contaminated by vapors from products in areas listed below , the acidic levels in the condensate increase.
