BY FOLLOWING THE INSTRUCTIONS BELOW, ADEQUATE COMBUSTION AIR CAN BE MAINTAINED * Unconfined area: A space whose volume is not less than 50 cubic feet per 1000 BTU per hour of all appliances installed in that space (cubic feet of space[...]

FIGURE 4 PAGE 4 FIGURE 3 FIGURE 2 5. When the boiler is installed in a confined space and all air is provided from the outdoors the confined space shall be provided with one or two permanent openings according to methods A or B. When ducts are used, they shall be of the same cross sectional area as the free area of the area of the openings to which[...]

CONNECTING SUPPL Y AND RETURN PIPING 1. Suggested piping for steam heating system can be seen in figure 5 below. Actual piping may vary based on system design and local conditions. 2. Suggested piping for a modular steam boiler using pumped returns may be seen in figures 6a and 6b on page 6. Actual piping may vary based on system design and local c[...]

VENT INST ALLA TION WARNING: This boiler shall not be connected to any portion of a mechanical draft system operating under positive pressure. 1. The vent pipe must slope upward from the boiler not less than 1/4 inch for every 1 foot to the vent terminal. 2. Horizontal portions of the venting system shall be supported rigidly every 5 feet and at el[...]

VENT SY STEM MODIFICA TION When an existing boiler is removed from a common venting system, the common venting system is likely to be too large for the proper venting of the appliances remained connected to it. If this situation occurs, the following test procedure must be followed: At the time of removal of an existing boiler, the following steps [...]

Remove Locknut from connector at the free end of the Damper wire harness. 3. Feed Damper connector and Damper wire harness through bracket hole on Damper Motor fram[...]

PAGE 10 CONNECTING GAS SERVICE Connect gas service meter to control assembly in accordance with the latest revision of ANSI Z223.1 and local codes or utility. A ground joint union should be installed for easy removal of gas control for servicing. A drip or trap must be installed at the bottom of a vertical section of piping at the inlet to the gas [...]

LIGHTING PROCEDURE FOR BOILER WITH INTERMITTENT PILOT SYSTEM. FOR YOUR SAFETY READ BEFORE OPERATING. A. This appliance is equipped with an ignition system which automatically lights the pilot. Do not try to light the pilot by hand. B. Before operating smell all around the appliance area for gas. Be sure to smell next to the floor because some gas i[...]

C. Use only your hand to push in or turn gas control knob. NEVER USE TOOLS. I f t h e knob will not push in or turn by hand, dont try to repair it, call a qualified service technician. Force or attempted repair may result in a fire or explosion. D. Do not use this appliance if any part has been under water. Immediately call a qualified service t[...]

PAGE 13 E. 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. LIGHTING INSTRUCTIONS FOR CONTINUOUS PILOT SYSTEM 1. Stop! Read the safety information at the beginning of this [...]

PAGE 14 NORMAL SEQUENCE OF OPERA TION On a call for heat: 1.) The thermostat will actuate completing the circuit between T and T. 2.) The damper will then open thus closing the end switch completing the circuit, and ignition will begin. 3.) In the event that the boiler steam pressure exceeds the pressure control setting, the pressure control will i[...]

PAGE 15 CONNECTING SUPPL Y AND RETURN PIPING , WA TER CHILLED MEDIUM 1. When the boiler is used in connection with refrigerated system, connect supply and return piping as suggested in figure 14 below. A. The chilled medium MUST BE IN PARALLEL with the boiler. B. Use appropriate valves to prevent the chilled medium from entering the heating boiler.[...]

PAGE 16 GENERAL INSTRUCTIONS Before seasonal start up it is advisable to have a competent service agency check the boiler for soot and scale in the flues, clean the burners, and check the gas input rate to maintain high operating efficiency. On steam boilers make certain the boiler is filled to the water line as indicated in figure 15. The gauge co[...]

T O CLEAN THE BOILER FLUEWA Y S: 1. Remove the burners from the combustion chamber by raising the burners upward from the manifold orifices and pulling toward the front of the boiler. To remove the burner with the pilot burner attached, first disconnect the pilot line tubing and thermocouple or pilot generator leads at the main electric gas valve. [...]

4. Electronic Low Water Cut-off: Operation may be checked by opening the drain valve in the back side of the boiler. This will drain the water from the boiler and break the electronic circuit to the automatic gas valve. IMPURITIES IN BOILER WATER of a steam boiler may cause foaming and an unsteady water line, or prevent steam generation. They may r[...]

PAGE 19 CHECKING AND ADJUSTING THE GAS IGNITION COMPONENTS The gas input to the boiler can be adjusted by removing the protective cap on the pressure regulator, see figure 16 on page 19 , and turning screw clockwise t o increase input and counterclockwise to decrease input. Natural gas manifold pressure should be set at approximately 3.5 inches wat[...]
