Overview

The provided document is a manual for the Evomax Multiline Flue Kit, designed for use with Ideal Commercial Evomax boilers (Type B23). This system allows multiple Evomax boilers to connect to a common flue header, facilitating a cascade flue arrangement.

Function Description

The Multiline Flue Kit enables the safe and efficient connection of multiple Evomax boilers to a shared flue system. Its primary function is to collect combustion products from individual boilers and discharge them through a common flue outlet. A key safety feature is the incorporation of non-return valves, which prevent the back-flow of combustion products into any individual boiler that is not currently firing. The system also manages condensate produced within the flue, draining it through a central trough in the header duct and exiting via a siphon.

The system is designed to accommodate various Evomax boiler models (30-150 kW and 30P-80P) and can be configured for both Natural Gas and Propane applications. It supports up to six boilers in a cascade, with a maximum system capacity of 600kW for Natural Gas (100, 120, 150 kW models) and 400kW for Natural Gas (30, 40, 60, 80 kW models) and Propane (30P, 40P, 60P, 80P models).

Important Technical Specifications

  • Boiler Compatibility: Evomax 30-150 kW and 30P-80P models (Type B23).
  • Maximum Boilers: Up to 6 boilers per system.
  • Maximum System Capacity:
    • 600kW for Natural Gas (100, 120, 150 kW combinations).
    • 400kW for Natural Gas (30, 40, 60, 80 kW combinations).
    • 400kW for Propane (30P, 40P, 60P, 80P combinations).
  • Flue Header Gradient: 3 degrees, falling towards the condensate drain end.
  • Flue Pipe Diameter: Must be at least 200mm. Larger diameters permit longer flue lengths.
  • Flue Material: Must be suitable for condensing operation (Polypropylene header and EPDM seal are certified to BSEN 14471).
  • Flue Terminal: Design should minimize resistance and prevent ingress of objects greater than 15mm diameter (e.g., wire mesh type with 14mm grid).
  • Non-Return Valves: Incorporated to prevent back-flow of combustion products.
  • Condensate Management: Integrated siphon for condensate drainage.
  • Flue Resistance: The static pressure generated against flue resistance at the connection point to the common flue must not exceed the maximum permissible header pressure (Pmax) specified in the manual (e.g., 40Pa for 400kW systems, 80Pa for 600kW systems).
  • Flue Extension Tube: Either 80mm or 100mm diameter, supplied in 500mm lengths.
  • Certifications: Polypropylene header and EPDM seal certified to BSEN 14471. Connecting flue must comply with CE approval requirements.

Usage Features

  • Modular Design: The system is supplied in two kits: a Starter Kit and Extension Kits. The Starter Kit provides components for the initial boiler connection, while Extension Kits allow for the addition of further boilers.
  • Push-Fit Connections: Polypropylene flue tubes are designed for easy assembly using push-fit connections with recessed flexible seals. Water is recommended as a lubricant for assembly.
  • Eccentric Valve Connector: The non-return valve connector has an eccentric axis, allowing for rotational adjustment to accommodate positional tolerances between the boiler and header, supporting both 30-80 models and 100-150 models within the same system.
  • Adjustable Flue Length: Extension tubes can be cut to the required length to achieve the necessary 3-degree header gradient for condensate drainage.
  • System Configuration Options: The manual highlights that different system configurations (e.g., choice of boiler models) will influence system capacity, number of boilers, turn-down capability, and permissible flue length.
  • Commissioning Procedure: A specific commissioning procedure is outlined to convert Evomax operation to "Multiline Flue" mode via the user interface control panel. This adjusts the minimum fan speed to offset the increased back-pressure from the common flue.
  • Installation with Frame & Header Kit: It is recommended that the Multiline Flue System be installed in conjunction with the Ideal Frame & Header Kit for optimal integration.

Maintenance Features

  • Wire Retaining Clips: Securing clips are provided and must be fitted to every flue connection to prevent movement due to expansion and contraction, ensuring safe operation. These clips locate under the rim of the female component and are secured by a nut and bolt.
  • Condensate Drain: The system includes a condensate drain and siphon. Proper termination of the condensate drain should follow the advice in the Evomax appliance's Installation and Servicing Instructions.
  • Spare Parts: The manual emphasizes the importance of using only genuine Ideal spare parts that conform to safety and performance specifications. Reconditioned or copy parts not authorized by Ideal should not be used.
  • Documentation: The latest literature for specification and maintenance practices is available for download in PDF format from the Ideal Commercial Boilers website.
  • Technical Training: Ideal Boilers offers first-class training courses for installers, engineers, and system specifiers, which can be beneficial for understanding the system's maintenance and operation.
