Installation & Operation Manual 8 Ratings Notes: 1. The ratings are based on standard test procedures prescribed by the United States Department of Energy. 2. Net I=B=R ratings are based on net installed radiation of sufficient quantity for the requirements of the building and nothing need be added for normal piping and pickup.
Installation & Operation Manual 9 1 Determine unit location NOTICE Clearances from combustible construction are noted on the appliance rating plate. Location of unit This unit meets the safe lighting performance criteria with the gas manifold and control assembly provided, as specified in the ANSI standards for gas-fired units, ANSI Z21.
Installation & Operation Manual 10 1 Determine unit location 2. Outside Combustion Air, Using Ducts You can direct outside combustion air to this unit using two air ducts to deliver the air to the boiler room (see FIG. 1-5). Each of the two openings must have a minimum free area of one square inch per 2000 Btu input (11cm 2 per kW).
Installation & Operation Manual 1 Determine unit location (continued) 11 Figure 1-5_ Outside Combustion Air Through Ducts 4. Outside Combustion Air - Using Direct Venting With this option, you can connect combustion air vent piping directly to the unit.
Installation & Operation Manual 12 1 Determine unit location Exhaust fans Any fan or equipment which exhausts air from the boiler room may deplete the combustion air supply and/or cause a down draft in the venting system.
Installation & Operation Manual 13 2 Venting BEFORE YOU BEGIN Identify your appliance’s vent system: This manual covers venting requirements for CAT I models and CAT IV vent materials. Be sure to correctly identify the type of vent system your appliance requires before proceeding.
Vent system options: (Note: Installations shown below are representative, actual installations may vary from those shown.) A This option uses a vertical rooftop flue termination with air supplied from the equipment room - see page 16.
Installation & Operation Manual 2 Venting (continued) 15 TABLE - 2A FLUE AND AIR INLET PIPE SIZES MODEL FLUE SIZE AIR INLET SIZE MODEL FLUE SIZE AIR INLET SIZE* 402 6" 6" 992 10" 10.
A Conventional negative draft venting - see page 14. NOTICE Before installing a venting system, follow requirements found in the General Venting section. This option uses Type-B double-wall flue outlet piping. The blower brings in combustion air. The buoyancy of the heated flue products cause them to rise up through the flue pipe.
Installation & Operation Manual 2 Venting (continued) 4. Turn on clothes dryers and any other appliances not connected to the common venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they will operate at maximum speed.
Figure 2-1_ Vent Termination from Peaked Roof - 10 ft. or Less From Ridge NOTICE Vent terminations are not shown in FIG.’s 2-1 thru 2-4. Make sure all vertical vents are installed with vent terminations recommended by the vent manufacturer. Figure 2-2_ Vent Termination from Peaked Roof - 10 ft.
Installation & Operation Manual 2 Venting (continued) 19 The sidewall or vertical rooftop DirectAire™ combustion air supply system has specific material and installation requirements. The air inlet pipe connects directly to the unit to supply combustion air.
Installation & Operation Manual 20 2 Venting To prevent recirculation of flue products from an adjacent vent cap into the combustion air inlet, follow all applicable cleara nce requirements in the latest edition of the National Fuel Gas Code and/or CAN/CGA-B149 Installation Code and instructions in the Installation and Operation Manual.
Installation & Operation Manual 2 Venting (continued) 21 TABLE - 2B DIRECTAIRE KITS MODEL HORIZONTAL KIT* VERTICAL KIT* 402 SVK3047 VDK3026 502 SVK3047 VDK3026 652 SVK3048 VDK3027 752 SVK3048 VDK3.
Installation & Operation Manual 2 Venting 22 Sidewall venting - see page 14. NOTICE Before installing a venting system, follow all requirements found in the General Venting section. C This option uses a powered vent assembly which pulls the flue products out of the stack.
Installation & Operation Manual 23 2 Venting (continued) Sidewall venting without fan For Models 402 - 752 which are approved for sidewall venting without an external power vent fan, you must install specific vent kits and venting materials (reference Table 2C on page 24 for kit numbers).
Installation & Operation Manual 24 WARNING Do not combine the flue from this unit with the vent from any other appliance. Do not combine flues from multiple appliances into a common vent. The flue from this unit must be a dedicated stack. Connect the flue vent directly to the flue outlet opening on the top of the unit.
Installation & Operation Manual 2 Venting (continued) 25 Horizontal DirectAire™ venting (Powered Venting) - see page 14. The Horizontal DirectAire™ vent system is the same as the Sidewall Venting system, except it pulls combustion air from the outdoors through a sidewall air inlet.
Installation & Operation Manual 26 2 Venting E This option uses sealed AL29-4C vent materials for the flue outlet piping and separate combustion air inlet piping. This system terminates both the flue and combustion air inlet in the same pressure zone.
Installation & Operation Manual 2 Venting (continued) 27 Masonry chimney installation Do not use a standard masonry chimney to directly vent the combustion products from this unit. To use a masonry chimney, the chimney must use a sealed, corrosion-resistant liner system.
Installation & Operation Manual 2 Venting Length of air inlet pipe The installed length of air inlet pipe from the unit to the outside air inlet cap must not exceed 50 equivalent feet (15.2m). Subtract 5 feet (1.5m) of equivalent length for each 90° elbow.
Installation & Operation Manual 2 Venting (continued) 29 2. For PVC, CPVC, ABS, dryer vent, or flex duct air inlet piping, use a silicone sealant to ensure a proper seal at the unit inlet and the air inlet cap. 3. For Dryer vent or flex duct, also use a screw-type clamp to attach the inlet vent material to the unit inlet and the air inlet cap.
Installation & Operation Manual 30 2 Venting Outdoor installation - see page 14. NOTICE Before installing a venting system, follow all requirements found in the General Venting section. Units are self-venting and can be used outdoors when installed with the optional outdoor cap.
Installation & Operation Manual 31 3 Gas connections Connecting to gas supply Verify that the appliance is supplied with the type of gas specified on the rating plate. This appliance is configured for operation up to 4,500 feet altitude. Consult factory for installations above 4,500 feet elevation.
Installation & Operation Manual 32 3 Gas connections 2. Use new, properly threaded black iron pipe free from chips. If you use tubing, make sure the ends are cut square, deburred and clean. Make all tubing bends smooth and without deformation. Avoid flexible gas connections.
Installation & Operation Manual 33 3 Gas connections (continued) Figure 3-3_ Measuring Gas Supply Pressure at Combination Gas Valve 13. Remove the manometer and related fitting from the “inlet” side of the gas valve, replace 1/8" hex plug in gas valve and tighten.
34 Installation & Service Manual 4 Water connections Figure 4-1_ Water Connections - Models 402 - 752 Heat exchanger This appliance uses a finned copper tube heat exchanger to maximize the heat transfer process. The heat exchanger is mounted in the inner jacket of the appliance.
Installation & Operation Manual 35 Relief valve This unit is supplied with a relief valve(s) sized in accordance with ASME Boiler and Pressure Vessel Code, Section IV (“Heating Boilers”). The relief valve(s) is installed in the vertical position and mounted in the hot water outlet.
36 Installation & Service Manual 4 Water connections CAUTION At no time should the system pressure be less than 12 PSIG. Pump Maintenance: Inspect the pump every six (6) months and oil as necessary. Use SAE 30 non-detergent oil or lubricant specified by the pump manufacturer.
Installation & Operation Manual 37 CAUTION A boiler allowed to operate at set point temperatures below the specified minimum settings may experience operational problems with the operating controls and safety switches, obstruction of the flue gas passages on the heat exchanger, incomplete combustion and possible flue gas spillage.
38 Installation & Service Manual 4 Water connections The installer must ensure that the boiler is supplied with adequate flow without excessive temperature rise. It is recommended that this boiler be installed with a bypass in the piping if the maximum recommended flow rate is exceeded.
