Fiberglass wool and ceramic fiber materials: • POSSIBLE CANCER HAZARD BY INHALATION • CAN CAUSE RESPIRATORY, SKIN AND EYE IRRITATION This product contains fiberglass wool and ceramic fiber materials. Airborne fibers from these materials have been listed by the State of California as a possible cause of cancer through inhalation.
3. Non-Packaged WGO-7, 8 & 9 — install flue collector hood (see FIGURE 3): Obtain gas-tight seal to prevent possible flue gas leakage and carbon monoxide emissions, leading to severe personal injury or death. a. Thread tinnerman clip on screw so that clip fits snugly in notch of hold-down lug.
Perform hydrostatic pressure test: 1. See FIGURE 4 and Control Tapping Table below to install: a. Boiler drain. b. Water pressure gauge (test only). Be sure gauge can handle test pressure. c. Air vent in upper “N” tapping. d. Plugs in remaining tappings.
For P-WGO and A-WGO boiler: 1. Secure universal mounting flange and gasket to burner mounting door. Use three bolts provided. 2. Secure burner on flange with three bolts. 3. Position burner so end of air tube is level to 1 ½ ° tilt downward. Open door to verify burner position.
General chimney requirements: • Designed for natural draft firing. Connect boiler to vertical chimney. Insufficient draft can cause flue gas leakage and carbon monoxide emissions, which will lead to severe personal injury or death. • Use vent material approved by local codes for oil-fired burners.
Connect Breeching CONTINUED Top Outlet Breeching Connection FIGURE 7 Back Outlet Breeching Connection FIGURE 6 Typical Location for Barometric Control (Also see Control Manufacturer’s Instructions) .
General piping information: • If installation is to comply with ASME or Canadian requirements, an additional high temperature limit is needed. Install control in supply piping between boiler and isolation valve. Set control to a minimum of 20°F above set point of combination control.
Connect Water Piping CONTINUED Piping with DIAPHRAGM Expansion Tank FIGURE 8 Piping with CLOSED Expansion Tank FIGURE 9 15 Isolation Valve Circulator Automatic Air Vent Relief Valve To Diaphragm Expan.
Piping MULTIPLE ZONES: 1. Follow instructions on page 14 and 15 to install piping near boiler. 2. See FIGURE 10 or 11 to complete installation 3. Zoning with circulators: a. Size each circulator to individual circuit requirements. b. Remove circulator (when furnished as standard equipment).
Piping for systems requiring temperatures below 140°F: In most systems, this type of piping is not required. If system water temperature requirements are less than 140°F, such as radiant panels or converted gravity systems, use piping as shown in FIGURE 12 or 13.
Use with refrigeration systems: • Install boiler so that chilled medium is piped in parallel with heating boiler. Use appropriate valves to prevent chilled medium from entering boiler.
General wiring requirements: Electric shock hazard. Can cause severe personal injury or death if power source, including service switch on boiler, is not disconnected before installing or servicing.

General oil piping requirements: • Location and installation of oil tanks, oil piping and burners must follow: — NFPA 31, Standard for the Installation of Oil-Burning Equipment. — In Canada, CSA B139, Installation of Oil-Burning Equipment. — Local codes and regulations.
Follow information below to prevent severe personal injury, death or substantial property damage: • Do not use gasoline crankcase drainings or any oil containing gasoline. See burner manual for proper fuel oil. • Do not attempt to start burner when excess oil has accumulated, when unit is full of vapor or when combustion chamber is very hot.
Check off steps as completed: ❏ 1. Boiler and heat distribution units filled with water? ❏ 2. Automatic air vent, if used, opened one full turn? ❏ 3. Air purged from system? Piping checked for leaks? ❏ 4. Air purged from oil piping? Piping checked for leaks? ❏ 5.
Burner adjustments for “P” and “A” boilers: Final burner adjustments must be made using combustion test equipment to assure proper operation. Do not fire boiler without water or sections will overheat. 1. Refer to burner manual for start-up. 2.
Close clearance installation: Substitute these instructions for corresponding material in manual. All other procedures and practices must remain the same.
PROTECTION REQUIRED FOR CLEARANCES LESS THAN 6 INCHES FROM DOUBLEWALL VENT PIPE* DIMENSION A When desired minimum clearance from type “L” doublewall vent pipe to Use the following combustible surf.
