NOTICE ! WARNING This boiler must be installed by a qualified service technician. Improper installation and/or operation can cause a potentially hazardous situation, which, if not avoided, could result in serious injury or death, and will void the warranty. The manufacturer cannot anticipate every circumstance that might involve a potential hazard. Each installation has its own specialized characteristics, requirements, and possible hazards.
D. When Servicing the Boiler ! WARNING Be sure to disconnect electrical power before opening boiler cabinet or performing service. Label all wires while performing service to ensure proper re-wiring of the boiler. Wiring errors can cause improper or dangerous operation. Failure to do so could result in an electrical shock, improper boiler operation, property damage, serious personal injury, or death. discontinue use of the boiler and contact an authorized technician or licensed professional.
H. Water Temperature Adjustment and Scalding This boiler can deliver scalding water. Be careful whenever using hot water to avoid scalding injury. Certain boilers such as dishwashers and automatic clothes washers may require increased water temperatures. By setting the thermostat on this heater to obtain the increased water temperature required by these boilers you may create the potential for scald injury. To protect against injury, install a mixing valve in the water system.
Part 2 - Before You Start Open the shipping crate of the boiler. NOTICE UNCRATING THE BOILER - Any claims for damage or shortage in shipment must be filed immediately against the transportation company by the consignee. A.
• Condensate Removal Pump (Part # 554200) • 2” Mesh Vent Screens (Part # 7850P-088) NOTE: When using an optional system sensor, pipe insulation must be wrapped around it to improve temperature measurement accuracy and increase overall system efficiency. Part 3 - Prepare the Boiler Installation Remove all sides of the shipping crate to allow the boiler to be moved into its installation location.
CAUTION Correct Installation Incorrect Installation Figure 1 - Leveled Boiler (Floor Model) ! WARNING The space must be provided with combustion / ventilation air openings correctly sized for all other boilers located in the same space as the boiler. The boiler cover must be securely fastened to prevent the boiler from drawing air from the boiler room. This is particularly important if the boiler is in a room with other boilers.
! WARNING Do not attempt to vent this appliance by any means other than those described in this manual. Doing so will void the warranty and may result in severe personal injury or death. Vents must be properly supported. Appliance exhaust and intake connections are not designed to carry heavy weight. Vent support brackets must be within 1’ of the appliance and the balance at 4’ intervals. Appliance must be readily accessible for visual inspection for first 3’ from the appliance.

! WARNING This boiler is too heavy for one person to lift. It is highly recommended to install the boiler with two people. Use caution as to not drop the boiler, which could damage the boiler and cause property damage and/or severe personal injury. Verify that the boiler is properly and securely mounted before leaving unsupervised. Failure to comply with the above and properly mount the boiler could result in substantial property damage, severe personal injury, or death.
Figure 8 - Water Pressure vs. Flow through the Restrictors - 140 Models Figure 9 - Water Pressure vs. Flow through the Restrictors - 199 Models Part 4 - Water Piping ! WARNING Failure to follow the instructions in this section WILL VOID the warranty and may result in property damage, severe personal injury, or death. CAUTION Do not apply a torch within 12” of the boiler. If sweat connections are used, sweat tubing to the adapter before fitting adapter to the water connections on the boiler.
• Pipe material must be suitable to meet local codes and industry standards. • The pipe must be cleaned and without blemish before any connections are made. • The size of the DHW pipes should be 3/4” diameter, and the CH pipes should be 1” diameter. • Isolation (shutoff valves) should be used on both the CH and DHW loops to ease future servicing. • All piping should be insulated. It is recommended to install a sweat shut-off valve and a union in the return and supply piping to ease future servicing.

2. Venting Through an Existing System This appliance may be vented through an existing unused vent system. The inner diameter of the existing vent system is utilized for the combustion air source. Two methods have been approved for such venting: Concentric Venting Through an Existing System and Venting as a Chase. ! DANGER Do not install the appliance into a common existing vent with any other appliance.
3. Power Venting, Indoor Combustion Air in Confined or Unconfined Space This appliance requires fresh, uncontaminated air for safe operation with doors, are considered part of the space. and must be installed in a mechanical room where there is adequate Confined space is space with volume less than 50 cubic feet per combustion and ventilating air. NOTE: To prevent combustion air 1,000 Btu/hour (4.8 cubic meters per kW) of the total input rating of contamination, see Table 7.
Part 6 - Installing the Condensate Drain CAUTION This condensing high efficiency boiler has a condensate removal system. Condensate is water vapor derived from combustion products, similar to that produced by an automobile when it is initially started. It is very important that the condensate line is sloped down away from the boiler and to a suitable drain. The condensate line must remain unobstructed.
Part 7 - Connecting Electrical Service ! WARNING Install wiring and electrically ground boiler in accordance with the authority having jurisdiction or, in the absence of such an authority, follow the National Electrical Code, NFPA 70, and/or CSA C22.1 Electrical Code-Part 1 in Canada.

Part 8 - Gas Connections ! WARNING FIRE AND/OR EXPLOSION HAZARD To avoid serious injury or death, the gas line installation and the gas line inlet pressure test must be done by a licensed professional. Ensure the gas on which the boiler will operate is the same type specified on the rating plate (natural gas or LP gas). This boiler must be converted into propane operation unless specifically manufactured for use with propane. Follow Gas Conversion Manual instructions (separate document).
! WARNING C. Additional Precaution for Excess Flow Valve (EFV) If an excess flow valve (EFV) is in the gas line, check the manufacturer’s minimum and maximum flow capacity ratings. An improperly sized EFV will not allow for a full flow of gas to the boiler and will cause the boiler to malfunction. See Figure 38. It is required to use a calibrated combustion analyzer to verify final adjustment according to the combustion chart (Table 25).
