The lens is easily removable and replaceable to give ready access to the display as needed.
19EBM-Papst Blowers Dungs Gas Valves Extensively Field-Tested by Peerless Patented Whirlwind Technology Promotes Better Fuel/AirMixing for Better CombustionThe blower, the gas valve and the swirl plate are all available as separate replacement parts from Parts To Your Door. The Gas valve is field convertible from Natural Gas to LP gas and vice versa, but only when an electronic combustion analyzer is used to measure CO and CO2 during and after the conversion.Fuel Conversion Instructions and Labels are included with all PureFire Boilers. No additional parts are needed. Fuel Conversion is normally done by adjusting the throttle screw (with an electronic combustion analyzer) by turning it with a small slotted screwdriver counter-clockwise toward the + sign on the valve body or turning clockwise toward the - sign on the valve body.The gas valve Offset adjustment is set at the factory and sealed with orange wax. It should never be adjusted without consulting PB Heat Technical Support and must always be done using an electronic combustion analyzer.For Best Combustion results and most trouble-free operation the CO level should always be under 100 ppm in all conditions and should be set for the midpoint of the allowed CO2 range: 9% for Natural Gas and 10% for LP gas.Various Swirl Plates for Different Boiler Sizes

21Worgas Metal Mesh Burners Provide Stable and Reliable Flame Igniters & Flame Sensors Provide Dual Sensing of Burner Flame – Help Prevent Unnecessary LockoutsDual Sensing –Flame sensor sends small electrical current through burner flame back to the ignition control. Control must read the correct signal to prove flame.After Ignitor has lit the burner and turned off, it also sends the same signal through the flame as a back up for the flame sensor.As long as the control reads the correct signal through the flame from either source it proves the flame and keeps the boiler from locking out.
22Molded Plastic Vessels for Condensate Collection & Neutralizing The Condensate Collector Vessel located at the back of the boiler under the heat exchanger receives the condensate from both the heat exchanger and the vent system. In the PF-50 through PF-140 there are separate condensate hoses for each.This Vessel has a float switch to shut off the boiler in the event that the condensate flow is blocked downstream. From this vessel the condensate flows to the Neutralizer Vessel in the front of the boiler. When the condensate level rises (in both Vessels) to the level of the Neutralizer Vessel Outlet, the condensate flows out through the fitting in the boiler jacket into the rest of the condensate drain system.All PureFire boilers are shipped with an initial supply of Neutralizer material (marble chips), which are designed to slowly dissolve into the condensate flowing through it, thereby reducing the acidity of the condensate, which is often required by local codes.The marble chips may last a few years depending on the operating temperature of the boiler, which affects the amount of condensate that is produced. Additional marble chips are available through Parts To Your Door or local suppliers.Optional for PF-210 & 399
23Simplified Electrical Connections Pre-Wired Harnesses & Split Terminal Strips The Factory Pre-Wired Harnesses feature a removable terminal strip that allows the installer more room to attach field wiring. Once all leads are connected to the terminal strips, they can be reattached to the harnesses.The terminal strip on the left of the wiring box is for all low voltage wires, including sensors and circuit switches.The terminal strip on the right of the wiring box is for all line voltage wires, including incoming power, circulator pump relays, etc.The two bottom terminals on the low-voltage harness is pre-wired with a jumper for test-firing the boiler. It should be removed before attaching the wires to the switch on the Low-Water Cut-Off (or Flow Switch) device.The green plastic plug with two wires in the wiring box is designed to be connected to an optional PureFire PC mouse for use with customer software.The PF-210 and PF-399 models have four more terminals than the PF-50 through PF-140 models for additional features.
24Additional Features Leveling Legs Courtesy Outlet All PureFire boilers are built with leveling legs to allow proper pitch of the boiler. Boilers should be level from side to side and pitched slightly back to direct all condensate inside the heat exchanger to the condensate drain.All PureFire boilers are built with a courtesy outlet, which is typically used to power a condensate pump or other accessory devices. The outlet power is always on whenever there is power to the boiler, even if the service switch on the boiler is turned off. This allows a service light to be used when inspecting a boiler that is turned off. It is important not to overdraw the power outlet with devices that are not related to the boiler.Leveling LegsCourtesy Outlet
25FeaturesBE SURE TO USE ONLY PUREFIRE SENSORS AND REPAIR PARTS ON PUREFIRE BOILERS. Other repair parts and especially OTHER SENSORS (including Pinnacle Gas) may have different specifications which will not work properly, causing possible malfunctions and safety hazards.The Outdoor Sensor and two Knockout Grommets are provide with all PureFire Boilers. The Knockout Grommet protects the low-voltage wires from being cut or chafed on the steel edge of the knockout and helps seal the PureFire boiler jacket. All low-voltage wires can be routed through a single grommet (or two if needed.)In order for the OutDoor Reset (ODR) function of the PureFire control to work, the Outdoor Sensor (ODS) must be attached to an outdoor location, preferably on a North-facing wall out of direct sunlight. A wood screw and wall anchor are provided for attaching the ODS to a wall.Standard low voltage (18 gauge) thermostat wire can be wired from the terminals under the ODS cover to the ODS terminals on the left side of the PureFire wiring box.A hole can be punched through the rubber grommet on the ODS with a small nail, awl or screwdriver for the wires to pass through. By pressing the two small orange retaining clips inside the ODS the stripped wires will slide into the terminals. The ODS should always be installed with the rubber grommet facing down so that water such as from rain or melted snow won’t flow inside and short the sensor.If the ODR feature on the PureFire control is turned on and the ODS is not connected (or has a broken wire) the PureFire Display will blink continuously. To stop the Display from blinking, turn off the ODR feature in the PF control until the wires are reattached or repaired.Note that the PureFire System sensor looks similar to the ODS except that it has a spring clip and cable tip for attaching it to a pipe instead of a center hole, screw and wall anchor.Outdoor Sensor For Outdoor Reset(Supplied as Standard Equipment)Knock-out Grommet For Low-Voltage Wires Helps Protect Wires & Keep Cabinet Sealed
26Venting Options: PVC, CPVC & PP (M&G) with Stainless Steel, Concentric PVC & PP Termination Options Standard Vent Terminations are a PVC Tee for Combustion Air Intake and a separate PVC Coupling for the Exhaust Vent. Both PVC fittings come with a heavy gauge wire varmint screen to prevent birds and rodents from entering the venting.See Venting instructions in PureFire IOM for proper vent and termination installation. Be sure to follow instructions and good venting practices to ensure trouble-free operation and avoid cross-contamination of the flue gasses into the combustion air.
27Control Display Sample Screens Boiler Control Display has 4 lines of 20 letters each to show what the boiler is doing and allow the user or installer to adjust settings.Standby means that the boiler has no call for heat or domestic hot water. The Control Display normally shows the current time (24-hour military format) and the boiler water supply temperature.The Control Display shows whether it’s in Central Heating mode or Domestic Hot Water Mode. The Trial For Ignition includes the blower pre-purge time, spark ignition and flame stabilization and proving time.
28Control Display Sample Screens During a normal call for Central Heating or DHW , the Control Display shows the burner input rate as a percentage: 1% is minimum input and 100% is maximum input.Once the boiler reaches the setpoint, the blower goes into post-purge, which is shown on the Control Display.If there is a call for Central Heating, but the boiler supply water is already at or above the setpoint, the burner will stay off and the circulator(s) will stay on until the supply water temperature drops below the setpoint minus the differential.For example, if the Central Heating setpoint is 120º because of Outdoor Reset and the boiler is at the end of a call for DHW and the supply water is near 180º, the boiler will wait until the supply water drops below 113º before firing the burner.
29Control Features New or Enhanced in 2009 Feature Description Cascade Multiple boilers operate together in order to satisfy the heating or DHW demand.One Hour RetryOne hour after a lockout on ignition or flame failure, the PUREFIRE control will reinitiate boiler operation.Restore System DefaultsAllows the installer to reset all parameters to the factory defaults if desired. The installer can also save and restore site defaults.Adjustable Blower PostpurgeThis feature allows the installer to increase the blower postpurge to counteract the effects of high winds or unusual wind currents.Flame Signal LogThis troubleshooting tool captures the flame signal at four increments during the two second flame proving period. This can help installers/service personnel to quickly diagnose problems with flame rectifications.Fault HistoryThe PUREFIRE control allows service personnel to access the last 15 Blocking Errors and the last 15 Lockout Errors in addition to records of the interval between Errors.

32Control Features Safety & Efficiency Feature Description Freeze ProtectionActivates pumps if temperatures fall below the specified value. If the temperatures continue to fall, the boiler is activated.Ramp Delay Step ModulationThis feature is used to prevent short cycling in systems using very small zones. The input rate is gradually increased from 20% to 100% over 2 minutes. When used, this only effects central heating operation.Add’l Safety FunctionsAllows the installer to choose between a low water cutoff and a flow switch for water level safety shutdown.Vent Temperature Safety LimitReduces the firing rate if the vent temperature approaches the maximum limit of the vent material. If the vent temperature continues to climb, the PUREFIRE control will shut down the boiler.Service NotificationIf enabled, the PUREFIRE control will display a service notification after an installer defined number of hours or cycles. It can also display a notification based on a date of the installers choosing.System TestThe PUREFIRE boiler will allow the installer to operate the boiler at low power, high power and ignition input for troubleshooting purposes.
33Control Features Central Heating Feature Description Outdoor Reset The PUREFIRE control changes the boiler supply target temperature to compensate for changes in load due to milder outdoor temperatures. This increases the efficiency of the boiler and is more comfortable.System Type PresetsBy choosing the heat distribution type (finned tube baseboard, hydro air, cast iron radiators, cast iron baseboard, low mass radiant or high mass radiant) the installer can automatically select practical boiler design and mild weather temperatures.Temperature BoostThe temperature boost function increases the boiler supply target to recover more quickly from setback conditions.Warm Weather ShutdownThe PUREFIRE control will shut down the boilers CH functions if the outdoor temperature is above an installer defined maximum. This prevents the boiler from running during warm weather.Anti-CyclingThe anti-cycling function prevents rapid on/off cycling of the boiler. This includes an override function to be sure that all loads are satisfied.The Anti-Cycling feature will keep the PureFire from firing in Heating Mode for 3 minutes if it reaches its setpoint, unless the difference between the boiler heating setpoint and the boiler supply temperature measured by the supply sensor is more than 30º. The time cycle-off time (3 minutes) and the temperature difference (30º) can be adjusted or turned off by the installer.
34Outdoor ResetIn addition to Outdoor Reset Design (coldest) and Mild Weather setpoints, a Boiler Maximum and Boiler Minimum may be set.Boiler minimum is typically used with a HydroAir system where the boiler supply temperature to the HydroAir coil should be above 130º – 140º in order to avoid warm air that feels cold from coming off the coil. Even if the Outdoor Reset temperature calls for a lower temperature the setpoint will always target at or above the minimum.Boiler Maximum is typically used in a single temperature radiant system without DHW where too high a boiler supply temperature going directly to the radiant tubing could cause problems, such as damage to hardwood floors. Even if the Outdoor Reset temperature calls for a higher temperature the setpoint will always target at or below the maximum.It is important to note that the Temperature Boost Function of the PureFire Boiler starts adding to the ODR temperature which may be below the Boiler Minimum. In many cases it is a good idea to set the Mild Weather Supply temperature to the same number as the Boiler Minimum.

Press ▲ (up arrow) once which will change CH Mode to 1 Thermostat and Outdoor Reset. Press Select to stop Thermostat and Outdoor Reset from blinking, which finalizes the selection.CH Modes 2-6 are not yet fully or rarely used.
36Control Features Domestic Hot Water Feature Description DHW Tank Warm HoldPrevents boiler from ramping up to high power if the DHW demand is only to keep the tank warm.Limited DHW PriorityThe PUREFIRE control provides DHW priority for boiler operation. However, the control will automatically switch between CH and DHW loads after an installer determined switch time.DHW Heat DumpIf enabled, the DHW heat dump function serves to dump heat from the boiler system to the DHW tank after a CH demand has ended.The DHW Tank Warm Hold only works if DHW Mode is set to 1 (DHW Store with sensor). The boiler watches the DHW tank temperature constantly and can tell the difference between a quick drop in temperature indicating a demand (laundry, shower, etc.) and a slow drop in temperature over a few indicating standby loss.A DHW demand brings a full boiler response (usually full input to 180° setpoint.)A DHW standby loss brings a minimum boiler response (minimum input until tank temperature is restored.)If the boiler goes into DHW Tank Warm Hold then gets a demand, it will change over to full response immediately.Limited DHW Priority when there is a call for both Central Heating (CH) and DHW will give power to the DHW Circ Pump Relay and set the boiler setpoint for DHW for 30 minutes (which is adjustable in Priority Switch Time in the DHW Settings submenu). The CH demand would then get 30 minutes priority, and priority would switch back and forth as long as there is a demand for both CH and DHW. The DHW Circ Pump Relay and CH Circ Pump Relay will never be powered at the same time.DHW Priority is important when the boiler is not sized to always handle both DHW and CH at the same time. Proper boiler sizing is important for the most efficiency.Limiting DHW priority is useful in the case that the DHW circ pump fails. Not only would the DHW demand not be met but without a limit on DHW priority the lack of CH could cause the house to go cold and potentially freeze the pipes.
37DHW Mode Choices DHW Mode Display Text Description No DHW No DHWNo domestic hot water tank is used. (Factory Default)1DHW store with sensorThe domestic hot water tank is equipped with a temperature sensor. The PUREFIRE control modulates the boiler firing rate based on tank temperature.2DHW store with thermostatThe domestic hot water tank is equipped with a thermostat. The PUREFIRE control responds to the demand from the thermostat and modulates the boiler firing rate targeting the DHW boiler setpointTo turn on one of the Domestic Hot Water functions, enter the DHW Settings of the Installer Menu. The first sub-menu item is DHW Mode and the default setting is 0. Press Select and No DHW will begin blinking. Press ▲ (up arrow) once which will change CH Mode to 1 DHW Store with sensor or press ▲ (up arrow) twice which will change CH Mode to 2 DHW Store with thermostat. Press Select to stop the selection from blinking, which finalizes the selection.Optional PureFire DHW sensors are available from Parts To Your Door that fit a variety of Indirect Water Hot Water heaters, especially the Peerless Partner.The DHW sensor is attached to over 24” of low-voltage wire, which can be connected with wire nuts to standard (18 gauge) thermostat wire and connected to the DHW sensor terminals on the left side of the PureFire wiring box.As an alternative a standard DHW thermostat, such as a Honeywell L4080B, can be used instead of the DHW sensor using the same wiring box terminals. The PureFire Main Control can tell the difference whether one or the other is connected; however if DHW store with sensor mode on the PureFire control is selected and the DHW sensor is not connected (or has a broken wire) the PureFire Display will blink continuously. To stop the Display from blinking, turn the DHW Mode in the PF control to 0 or 2 until the wires are reattached or repaired.
38Pump Mode Choices Pump Mode Display Text Description Detail DHW or CH & DHW pumpThe General pump is on when the CH pump runs on CH demand. The DHW pump runs on DHW demand. Either the CH or DHW pump runs; they never run at the same time. (Factory Default)1General pump with 3-way valveThe General pump is always on when burner is on. A line voltage (120 VAC) 3-way valve is operated to supply water to the DHW tank.2Manifold with pump for DHWThe General pump is always on when the burner is on. The CH pump runs on CH demand. The DHW pump runs on DHW Demand. Either the CH or DHW pump runs; they never run at the same time.Virtually all applications use Pump Mode 0 .
39Typical Cast Iron Boiler Piping Parallel Piping Conversion to Primary/Secondary Primary/Secondary Piping is recommended for all PureFire installations to assure proper flow, because they hold a lower volume of water compared to a cast iron boiler, which increases their efficiency
