7 GENERAL SAFETY T o meet commercial water use needs, an external operating control for this hot water boiler is adjustable up to 210°F . However , water temperatures over 125°F can cause instant severe burns or death from scalds. The preferred starting point for setting the control for supplying general purpose hot water is 125°F .
Equipment Base The boiler should be mounted on a level, structurally sound surface. The boiler is approved for and can be installed on a combustible surface but must NEVER be installed on carpeting. Gas fueled equipment installed in enclosed parking garages must be located at least 18 inches above the floor .
9 Outdoor Installations Raypak Advanced Design Boilers are design certified by CSA for outdoor installation. Roof water drainage must be diverted away from boilers installed under overhangs.

of 1 million BTUH. This opening(s) shall be either located at or ducted to a point neither more than 18 inches (450 mm) nor less than 6 inches (150 mm) above the floor level. The duct can also "Goose Neck" through the roof. The duct is pre- ferred straight down 18 inches from floor , but do not place near piping.
HYDR ONIC HEA TING 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 ΔT as design ΔT . (ΔT is the temperature dif ference between the inlet and outlet water when the boiler is firing at full rate).

19 POOL HEA TING The ADB unit is equipped with an external pump and bypass arrangement that blends outlet water with the inlet to increase the inlet water temperature, thereby reducing the likelihood of condensation forming on the heat exchanger . The pump also serves to circulate water through the heater form the main system piping.

22 Fig. 16: Connections Gas Supply Connection The boiler must be isolated from the gas supply piping system by closing the manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 PSIG.
23 Gas Pressur e R e gulator The gas pressure regulator is nominally preset to the outlet values shown in T ables T and U, within +.1 in. WC. If an adjustment is needed, turn the adjustment screw clockwise to increase pressure or counterclock- wise to lower pressure.
"TH" leads. Before starting the boiler , ensure that there is proper voltage to the boiler and pump. The boiler must be electrically grounded in accordance with National Electrical Code ANSI/NFP A No. 70 and CSA C22.1 C.E.C. Part 1 in Canada.
25 VENTING CONNECTIONS General Definition of A ppliance Ca te gories Boilers are divided into four categories based on the pressure produced in the exhaust and the likelihood of condensate production in the vent.
26 Deter mination of A ppliance Categor y for V enting Pur poses and V enting Ar rangements Suppor t of V ent Stack The weight of the vent stack or chimney must not rest on the boiler vent connection. Support must be provid- ed in compliance with applicable codes.
27 e) T erminate vent at least six (6) feet away from adja- cent walls. f) DO NOT terminate vent closer than five (5) feet below roof overhang. Canadian Installations Refer to the latest edition of CSA B149 Installation Code.
28 Natural Draft V er tical V enting with- out Add-on Condensing Heat Exc hanger (Categor y I) Fig. 21: Natural Draft V ertical V enting without Add-on Condensing Heat Exchanger (Category I) NOTE: *Rear venting is recommended to minimize interference with water piping **V ent lengths are based on a lateral length of 2 feet.
29 Natural Draft V er tical 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 neg- ative draft must be within the range of 0.
30 appliance not connected to the common vent sys- tem. T urn on any exhaust fans, such as range hoods and bathroom exhausts, so they will oper- ate at maximum speed. Do not operate summer exhaust fan. Close fireplace dampers. d) Place in operation the appliances being inspected.
31 Horizontal Thr u-wall Dir ect V enting System (Categor y III) Installation These installations utilize the boiler-mounted blower to vent the combustion products to the outdoors. Combustion air is taken from inside the room and the vent is installed horizontally through the wall to the out- doors.
32 T able M: Horizontal Thru-wall Direct V enting without Add-on Secondary Condensing Heat Exchanger Horizontal Thr u-wall Dir ect V enting System (Categor y III) Installation These installations utilize the boiler mounted blower to draw combustion air from outdoors and vent combus- tion products to the outdoors.
33 This type of installation can cause non warrantable problems with components and poor operation of the unit due to the recirculation of flue products. Multiple direct vent caps, when installed in the same horizontal plane, should have three (3) foot clearance from the side of one vent cap to the side of the adjacent vent cap(s).
34 V er tical Direct V enting System Installation These installations utilize the boiler mounted blower to draw combustion air from outdoors and uses the natu- ral buoyancy of the heated flue products to create a thermal driving head that expels the exhaust gases from the flue.

41 CONTR OLS Centr al P oint W iring (CPW) Central Point Wiring is an advanced control integration technique that provides complete boiler diagnostic capability and greatly simplifies troubleshooting.
42 Fig. 30: CPW Board Pump T ur n-of f Delay The CPW board has a built-in pump driver with pump turn-off delay , which allows the operator to set how long the pump will run after the boiler shuts off. The delay is factory-set for 7 minutes but can be field- adjusted from 3 minutes to 10 minutes.
43 U-2 Diagnostics Boar d The U-2 Diagnostics board is a solid-state electronic fault indicator that has been engineered to enhance safety , simplify troubleshooting and minimize equip- ment down time. The U-2 safety board is the central point for wiring, operations monitoring, and fault indi- cation for the boiler safeties.

45 Ignition Control Module The intermittent ignition device conserves energy by automatically extinguishing the pilot when the desired temperature is reached. When additional heat is need- ed, the combustion air blower starts to purge all air from the combustion chamber for about 45 seconds.
46 Lo w Wa ter Cut Of f (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.
47 result in a fire or explosion. 5. Do not use this appliance if any part has been under water , immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water .
48 ADB INITIAL ST ART -UP T ools Needed • One 8-0-8 , 16” scale manometer (or larger) • Four 4-0-4, 8” scale manometers (or larger) • “T” fitting • 7/16” and 1/2" open end wrenches • Small and large flat-head screwdrivers • V olt meter • Amp probe • Elec.
49 tion wire and proper grounding and wiring. T urn power back on. Repeat Step 3. If there is still no spark after several attempts the igniter may be misaligned; 5. Check to see if igniter is grounded out by pulling the spark wire and doing a continuity check between the igniter and burner .
50 Main Bur ner Adjustment 1. T urn on the unit; about 45 seconds later , the pilot should light. If the pilot fails to light, repeat pilot adjustment. 2. Turn the top manual valve on, Location (2). The inner burner will fire. 3. Make sure that the supply gas manometer reads between 7 – 14 in.
51 burners should reignite after pre-purge time delay . 8. T est limit control: While burner is operating, move indicator on high limit control below actual boiler water temperature.
52 3. Visually inspect venting system for proper func- tion, deterioration or leakage. 4. Check that boiler area is free from combustible materials, gasoline, and other flammable vapors and liquids. 5. Check for and remove any obstruction to the flow of combustion or ventilation air to boiler .
53 10. Connect the flue vent (Category IV venting, UL 1738 Certified V enting Material) to the 15° elbow of the CHX flue outlet. 1 1. Connect the PVC pipe (not supplied) for conden- sate water disposal (check with local authority regarding condensate disposal).
54 APPENDIX Inside Combustion Air Contamination: 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.
