Page 14 SECTION 2 Venting and Combustion Air 2.A General Venting Information WARNING Selection of improper vent materials for installations that are installed in closets, or will be operated in high ambient temperature levels, may lead to property damage, personal injury, or death. WARNING Failure to use the appropriate vent material, installation techniques, or glues and sealants could lead to vent failure causing property damage, personal injury or death.
Page 15 a tee with the branch connection sized to allow for insertion of a flue gas analyzer probe. The branch connection must be resealable with a cap or other means to ensure the vent system remains sealed. (See Figure 4) Consideration must be given to the placement and orientation of the flue gas sampling port to ensure that condensate is free to flow back into the unit and not collect anywhere in the vent system - including in the flue gas sampling port. 2.B.1.b Exhaust Vent Terminal Figure 4.

Page 17 2.C.1 2.C.2 Category lV Vent Sizes Non-positive pressure vent systems are generally vertically terminated. Table 10 gives guidelines for vent and air pipe sizes. Positive pressure vent systems may be either horizontally or vertically vented. The vent pipe used must be suitable for positive pressure. Table 10 shows the pipe size and allowable maximum equivalent of piping allowed for both air and vent in a Category lV system.
Page 18 2.C.4 Common Vent Test NOTE: This section does not describe a method for common venting this unit. It describes what must be done when an unit is removed from a common vent system. This unit requires special vent systems and fans for common vent. Contact the factory or your factory representative if you have questions about common venting this unit.
Page 19 2.C.5 Combustion Air Boilers must have provisions for combustion and ventilation air in accordance with the applicable requirements for Combustion Air Supply and Ventilation in the National Fuel Gas Code, ANSI Z223 1; or in Canada, the Natural Gas and Propane Installation Code, CSA B149.1. All applicable provisions of local building codes must also be adhered to. This unit can take combustion air from the space in which it is installed, or the combustion air can be ducted directly to the unit.
Page 20 2.C.5.b Ducted Combustion Air The combustion air can be taken through the wall, or through the roof. The manufacturer offers accessories to use with ducted air systems, as shown in Table 9. See Table 8 to select the appropriate diameter air pipe. When taken from the roof, a field-supplied rain cap or an elbow arrangement must be used to prevent entry of rain water. (See Figure 7).

Page 26 SECTION 5 Boiler Piping 5.A Boiler Water Connections NOTE: This unit must be installed in a closed pressure system with a minimum of 12 psi (82.7 kPa) static pressure at the boiler. The water piping should be supported by suitable hangers or floor stands. Do not support the piping with this unit. The hangers used should allow for expansion and contraction of pipe. Rigid hangers may transmit noise through the system resulting from the piping sliding in the hangers.
Page 27 5.D Suggested Boiler Piping Schematics On innitial installations, drain and flush the system before adding propylene glycol. Sludge and other sediments in the boiler can inhibit flow, resulting in rapid breakdown of glycol. Check the propylene glycol concentration annually. Add more water or propylene glycol as needed. This boiler is a high efficiency appliance.

Allow the system to fill slowly. 2. If a make-up water pump is employed, adjust the pressure switch on pumping system to provide a minimum of 12 psi (81.8 kPa) at the highest point in the heating loop. 3.
Page 109 10.B Initial Operation The initial setup must be checked before the unit is put into operation. Problems such as failure to start, rough ignition, strong exhaust odors, etc. can be due to improper setup. Damage to the boiler resulting from improper setup is not covered by the limited warranty. 10.B.1 Initial Burner Operation 1. Using this manual, make sure the installation is complete and in full compliance with the instructions and all local codes. 2.
Page 110 10.B.2 Combustion Setup Procedure Hi-Fire, Low-Fire The gas system must be set up properly, so the boiler will run efficiently throughout its modulation range under the installed conditions. This setup should only be performed by a factory trained technician. 1. S et up a gas pressure gage (monometer) on the incoming gas line. A test plug is provided on the back of the boiler gas line. If the gas pressure is greater than 10.5” w.c.

I f needed, adjust the fuel pressure adjustment screw (See Figure 51) to obtain a Hi-Fire CO2 measurement of 9.0% +/- 0.2%. NOTE: Turn the adjustment screw only a quarter turn per adjustment either up or down, then watch the combustion analyzer for the result.
Page 112 10.C Shutting Down the Unit 10.E Controllers 1. Turn off the main electrical disconnect switch. 2. Close all manual gas valves. This unit utilizes three (3) separate controllers to manage system functions, burner management and air/ fuel ratio control: This step must be performed by a qualified service person. 3. If freezing is anticipated, drain the unit and be sure to also protect the building piping from freezing.
Page 113 10.F Transmitters This unit utilizes a pair of pressure transmitters to determine that the pressure drop across the combustion air/flue gas side of the system is within acceptable bounds for proper operation. If during operation the differential pressure across the system exceeds a predetermined value at a given firing rate, the system will shut down and a “Burner An Pressure Error” will be displayed.
Page 114 SECTION 11 Maintenance 11.A System Maintenance Do the following once a year: 1. Lubricate all the pumps in the system, per the instructions on the pump. 2. Inspect the venting system for obstruction or leakage. Periodically clean the screens in the vent terminal and combustion air terminal (when used). 3. Remove and inspect the air filter. Clean with soapy water if needed. Be sure that filter is dry before reinserting back into air filter box. Replace air filter if damaged. 4.
Page 115 installed the cables should be properly coiled and secured and reconnected to the LMV. In the event of failure of the on/off Honeywell solenoid, the entire valve must be replaced. Replacements solenoids are not available from Honeywell at this time. For the pressure regulating valve, the upper half of the valve may be replaced leaving the valve body in place. Care must be taken to replaced the fuel and air side sensing lines connected to the pressure regulator.
Page 116 11.B.7 Heat Exchanger Tubes Black carbon soot build-up on the internal surfaces of the heat exchanger is caused by one or more of the following: incomplete combustion, combustion air problems, venting problems or boiler short-cycling. Soot buildup or other debris on the heat exchanger may restrict the flue passages. If black carbon soot buildup on the heat exchanger is suspected, disconnect the electrical supply to the unit and turn off the gas supply by closing the manual gas valve on the unit.
