TABLE OF CONTENTS Introduction Dimensions ..........2 Boiler is designed for use in closed heating systems where Ratings and Capacity ........3 all steam is returned as condensate and make-up water is Safety Symbols .......... 5 minimal. Boiler is not designed for or intended for use in open systems using 100% make-up water.
SAFETY SYMBOLS General Installation shall conform to requirements of authority having jurisdiction or in absence of such Boiler and venting installation shall be completed by requirements to the National Fuel Gas Code, ANSI qualified agency. Z223.1/NFPA 54. WARNING Where required by authority having jurisdiction, Fire, explosion, asphyxiation and electrical shock installation shall conform to Standard for Controls hazard.
LOCATING THE BOILER Locating the Boiler Select level location as centralized with piping system, Table 2 - and as near chimney as possible. Minimum Clearance Dimensions Place crated boiler at selected location. Remove all 6" crate material. Please recycle responsibly. Rear 6"...
SYSTEM PIPING WARNING Burn or Scald Hazard. Discharge line shall be installed to relief valve outlet connection to avoid burns, scalding, or water damage due to discharge of steam and/or hot water during operation. Discharge line shall: • Connect to safety valve outlet. Piped down to safe point of disposal. Check local codes for maximum distance from floor or allowable safe point of discharge.
SYSTEM PIPING Consider near boiler piping as part of the boiler for proper For pumped return systems, follow the condensate water level control and to produce dry steam. pump or boiler feed pump manufacturer’s instructions for proper installation and hookup. Correct near boiler piping is crucial to proper operation of In connecting the cold water supply to the water inlet boiler and heating system.

CHIMNEY AND VENT PIPE CONNECTION Place in operation the appliance being inspected. Follow Figure 7 - Typical Masonry Chimney Requirements the lighting instructions. Adjust thermostat so appliance will operate continuously. Test for spillage at the draft hood relief opening after 5 minutes of main burner operation.
VENT DAMPER OPERATION WARNING Figure 8 - Horizontal Installation Asphyxiation or burn hazard. Improper installation Horizontal Installation and operation of vent damper could result in serious Flow injury or death due to fire or to asphyxiation from poisonous gases such as carbon monoxide which is To Boiler Vent Damper odorless and invisible.
GAS SUPPLY PIPING Propane Installation CAUTION WARNING WHAT TO DO IF YOU SMELL GAS Fire, explosion, asphyxiation hazard. Verify boiler • Do not try to light any appliance. is equipped with propane gas orifices and gas valve • Do not touch any electrical switch; do not use is configured for propane.
ELECTRICAL WIRING Electronic Thermostats WARNING A. Some electronic thermostats may lose their Electrical shock hazard. Turn OFF electrical power memory or shut down. With probe type low water supply at service panel before making electrical cutoff, this may occur each time low water cutoff connections.
OPERATING INSTRUCTIONS For Your Safety Read Before Operating STOP! Read the safety information on this page. WARNING Set the thermostat to lowest setting. Turn off all electric power to the appliance. If you do not follow these instructions This appliance is equipped with an ignition device which exactly, a fire or explosion may result automatically lights the pilot.
OPERATING YOUR BOILER Thermostat WARNING A. Set thermostat to desired room temperature. Burn Hazard. Never run water into a hot empty B. Set thermostat to lower setting if heat is not boiler. Failure to follow these instructions could required result in death or serious injury. C.
CHECKING AND ADJUSTING Adjust Pilot Burner Figure 14 - Igniter Pilot flame should surround 3/8” to 1/2” of pilot sensor. See Figure 15. To adjust Flame. Remove screw cover over pilot adjusting screw. See Figure 13. Insert small screwdriver and adjust flame as needed. Turn screw counterclockwise to increase flame, clock- wise to decrease.

CHECKING AND ADJUSTING Adjust Steam Pressure Control Boiler Equipped With Optional WF-2U-24 Water Feeder • Steam pressure limit control (pressuretrol) shuts E. Continue thermostat call for heat after low water off gas to main burners when steam pressure in cut off recognizes low water condition. boiler reaches cut-off setpoint (i.e.
START-UP CLEANING • Maintain at least 180°F for 15 minutes to remove WARNING dissolved gasses from fresh water. Following service procedures must be performed • Shut off burners. by qualified service agent. Boiler owner shall not Allow system to operate for one week to give majority attempt these steps.
GENERAL MAINTENANCE Low Water Cut-Off Boiler Water Treatment Other Than Cleaners Low Water Cut-Off interrupts electrical current to burner In steam systems where system is tight, free from leaks, when water line in boiler drops to low level. and all steam is returned to boiler as condensate, amount of make up water is small.
SERVICE HINTS You may avoid inconvenience and service calls by checking these points before you call for service. CAUTION WHAT TO DO IF YOU SMELL GAS • Do not try to light any appliance. • Do not touch any electrical switch; do not use any phone in your building.
