OUTDOOR INST ALLA TIONS Raypak Hi Delta Heaters are design certified for outdoor installation. Heaters must not be installed under an overhang that is less than three (3) feet from the top of the heater . 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 heater 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 heater should be located so that any water leaks will not cause damage to the adjacent area or structures. CAUTION: This heater r equir es forced 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 ensure 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 dif ference between the inlet and outlet water when the heater is firing at full rate).

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 .
SECTION H: GAS SUPPL Y CONNECTIONS DANGER: Make sure the gas on which the heater will operate is the same type as specified on the heater model and rating plate. Gas piping must have a sediment trap ahead of the heater gas controls, and a manual shut-off valve located outside the heater jacket.
GAS PRESSURE REGULA TOR The gas valve pressure regulator(s) on the heater 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 · Safety wiring must be N.
MAKING THE ELECTRICAL CONNECTIONS Refer to Fig. #9403 W iring Connection, and W iring Diagram #152564. 1 . V erify circuit breaker is properly sized by referring to heater rating plate. A dedicated circuit breaker should be provided. 2 . T urn off all power to the heater .
ELECTRICAL CONNECTIONS - DOMESTIC HOT W A TER CAUTION: Label all wir es prior to disconnection when servicing contr ols. 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 heater . Definition of Appliance Categories Heaters 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 NFGC, or in Canada, the B149.
Support of V ent Stack The weight of the vent stack or chimney must not rest on the heater 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 .
28 SECTION J-1 Natural Draft V ertical V enting (Category I) NA TURAL DRAFT VERTICAL VENT NOTE: **V ent lengths are based on a lateral length of 2 feet.
• 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) 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 heater-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 -.
DIRECT VENT Horizontal Thru-wall V enting (Category III) HORIZONT AL THRU-W ALL VENTING T ABLE 33 SECTION J-3.
• Horizontal Thru-wall Dir ect V ent System (Category III) Installation These installations utilize the heater mounted blower to draw combustion air from outdoors and vent combustion products to the outdoors. The total length of the thru-wall exhaust vent cannot exceed forty (40) feet in length for the flue outlet.
DIRECT VENT V ertical V enting (Category I) VER TICAL VENTING T ABLE 35 SECTION J-4.
• V ertical Direct V ent System Installation These installations utilize the heater mounted blower to draw combustion air from outdoors and uses the natural buoyancy of the heated flue products to create a thermal driving head that expels the exhaust gases from the flue.
SECTION J-5 Outdoor Installation Outdoor models are self-venting when installed with the factory-supplied restricted direct vent cap and require no additional vent piping. This special vent cap is provided with the heater in accordance with CSA requirements.
SECTION K: CONTROLS W ARNING: Installation, adjustment and service of heater controls including timing of various operating functions must be performed by a qualified installer , service agency or the gas supplier . Failur e to do so may result in contr ol damage, heater malfunction, pr operty damage, personal injury , or death.
IGNITION MODULE Fig. J-3 MANUAL RESET HIGH LIMIT Fig. J-4 FLOW SWITCH THERMOSTAT CONTROL IGNITION CONTROL MODULE The interrupted proved ignition device conserves energy . When additional heat is needed, the combustion air blower starts to purge all air from the combustion chamber for about 15 seconds.
LOW W A TER CUT OFF (OPTIONAL) The low water cut off automatically shuts down the burner whenever water level drops below the level of the sensing probe. A 3-second time delay prevents premature lockout due to temporary conditions such as power fluctuations or air pockets.

SECTION P: OPERA TION OPERA TING INSTRUCTIONS Lighting Instructions 1. STOP! Read the safety information first. 2 . Set the thermostat to the lowest setting. 3 . Turn off all electric power to the appliance. 4 . This appliance is equipped with an ignition device which automatically lights the burner .
SECTION Q: MAINTENANCE SUGGESTED MINIMUM MAINTENANCE SCHEDULE: Regular service by a qualified service agency and maintenance must be performed to ensure maximum heater operating ef ficiency . Maintenance as outlined below may be performed by the owner .
APPENDIX A INSIDE COMBUSTION AIR CONT AMINA TION: All heaters 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.
