The same features which permit this boiler to achieve high-efficiency performance make it unlike most other boilers of this general size, so it is im- portant to understand how this boiler operates.
Reorder No. 5025-V1WHPK The safety labels shown above are affixed to your boiler. Although the labels are of high quality, they may become dislodged or unreadable over time. Contact Patterson-Kelley for replacement labels. 2.5 S AFETY RECAUTIONS Provide a suitable location for the boiler, away from...
• Overfire and underfire hazards! Possible fire, explosion, overheating, and component failure. Do not attempt to adjust firing rate of the boiler. The firing rate must be adjusted only by fac- tory-trained personnel. 2.5.3 Crush Hazards General Warning •...
1998 HCS, Inc. 800-748-0241 • Pressure hazard! Hot fluids. Install isolation valves on boiler water inlet and outlet. Make sure isolation valves are closed before servicing boiler. • Pressure hazard! Hot fluids. Annually test safety relief valve for proper operation.
3.3.2 Placement The boiler must be level to function properly. To as- sist in leveling the boiler, the four (4) leg bolts (1/2"- NC) holding the boiler to the shipping skid must be reinstalled in the threaded legs on the bottom. The...
* CSA minimum. Actual clearance depends upon stacking requirements. ** Service access need be only on one side of a boiler or row of boilers. Boilers may be installed immedi- ately adjacent to each other. However, P-K recom-...
If air is taken directly from outside the building, each opening should have a net free area of 1 square inch for each 4,000 Btu per hour of total boiler input. For instance, 300 square inches (2-1/12 square feet) are required for 1,200,000 Btu per hour input.
It is not necessarily the same size as the boiler connection. Correct sizing should be based on High fire input at a nominal -.04" w.c. draft pres- sure at the boiler outlet with a gross stack temp of 325º F and CO ratings at 7.5%.
At the time of removal of an existing boiler, while the other appliances remaining connected to the common venting system are not in operation, the following...

3.068 7.67 4.026 10.1 on the boiler. Gas piping should be installed in accor- dance with National Fuel Gas Code, ANSI Z223.1, latest edition, and any other local codes which may apply; in Canada see CAN/CGA-B 149. Note: See chart below for required pipe size, based on overall length of pipe from meter plus equivalent length of all fittings.
1/2 psig (14 inch w.c.). During any pressure testing of the gas supply piping system at pressures equal to or less than 1/2 psig (14 inch w.c.), the boiler should be isolated from the gas supply piping system by closing the manual shut- off.
The bottom connection to the boiler is the INLET and must be used for the return from the system. The top connection to the boiler is the OUTLET and must be connected as the supply to the system. Piping must be installed such that no piping stresses are transmitted to the boiler.
Filling To be sure that the boiler is not air-bound, open the pressure-relief valve located at the rear of the boiler. Leave the relief valve open until a steady flow of water is observed.
3. Water connections are complete, and the boiler and system have been filled and purged of air. 4. The boiler must be connected to a 120 volt / 60 Hz power source with proper polarity and dedi- cated machinery ground. Provide a disconnect having adequate overload protection.
3.11.4 Test of Low Gas Pressure Switch Manual Reset Gas Pressure Switch The boiler is furnished with a low gas pressure switch. The operation of this switch must be checked by slowly closing the main gas cock while the burner is operating. The switch should shut down the main burner.

(See the configuration menu.) Display HyS1 HyS3 The setpoint of the boiler is controlled by an out- F which is Set- door temperature sensor. As the outdoor tempera- ture falls the setpoint of the boiler is increased. The boiler modulates to maintain this setpoint. The F which is boiler functions as indicated in internal setpoint;...

® Modu-Fire Gas-Fired Boiler Analog Input Direct Drive The firing rate of the boiler is controlled by an ex- ternal analog signal, usually from a multiple boiler control. The boiler turns on and off as directed by the external control.

To change to manual operation press EXIT for 5 seconds. The LED above the hand symbol lights up. Change the firing rate of the boiler with The firing rate increases as long as The firing rate decreases as long as pressed.
The configuration level must be ad- justed by factory-trained personnel only. 3.12.1B Optional Remote Control This option is used when the firing rate of the boiler is controlled by an external analog signal, usually from a multiple boiler control. The boiler turns on and off as directed by the external control.
Check high fire and low fire again To adjust the gas pressure, remove the cover plate from the air / gas ratio control valve. Set the boiler at High fire as described in the boiler operation sec- tion of the manual. The High fire gas pressure is adjusted with the lower screw of the air / gas ratio control vale.
4.2 L IGHTING AND Do not use this boiler if any part has been under wa- ter. Immediately call factory-trained personnel to inspect the boiler and to replace any part of the con- trol system and any gas control which has been un- der water.
If overheating occurs or the gas supply fails to shut off, do not turn off or disconnect the electrical sup- ply to the pump. Instead, shut off the gas supply at a location external to the boiler. 4.3 T YPICAL...
WARNING! Check daily to be sure that the boiler area is free and clear of any combustible materials, including flammable vapors and liquids. The motorized gas valves contain hydraulic oil which may be hazardous to the environment.
2. Inspect combustion chamber through access door on front side of boiler. To remove doors, remove fasteners, pull door forward slightly, then pull upward. Note any signs of deteriora- tion. Take corrective action as necessary.
3. Remove the top panel of the inner cabinet. 4. Close the isolation valves to the system. 5. Drain the boiler. 6. Disconnect the supply and return lines. 7. Remove the manifold assembly containing the temperature-pressure indicator, relief valve and...
2. The water flow limit switch is closed when there is water flow through the boiler. Note: The closing of this switch does not prove that flow is adequate. Refer to Technical Data Sheet # TD110 for proper flow requirements.
Gas-Fired Boiler 14. When the load is below the low fire rating of the boiler the boiler will continue firing and the out- let water temperature will rise until it reaches the set point + hysterises value. At this point...
8 of the combustion control is de-energized, closing the pilot valve. Terminal 15 is ener- gized, providing power to the modulating con- trol of the boiler. If main flame has not been es- tablished, the unit will lock out on main flame failure.

® Modu-Fire Gas-Fired Boiler • Check the cabinet pressure for a minimum of 0.3" w.c. • Check burner is clean (refer to Section 5.2). Ignition Failure In the event the pilot flame is not detected by the UV scanner during the 10 second trial-for-ignition period (Step 9), the pilot gas valve and spark igni- tion are de-energized.
