    This is shown in the diagram. It is often necessary to install a longer flue system to cater for site conditions. There are several different flue system sizes available for the Victrix Zeus 20/27 boiler. Horizontal concentric kit 60 /100...
  • Page 7 Victrix Zeus 20/27 Instructions Separated Flue Systems Separated 80/80 flue kit This kit enables separation of the exhaust and air intake pipes as shown in the figure. Combustion products are expelled from pipe (A) (in plastic material resistant to acidic condensates). Air is taken in through pipe (B) (also in plastic material) for combustion.
  • Page 8 Victrix Zeus 20/27 Instructions Flue calculations for more complex systems Each component of the air inlet/flue system has a resistance factor . These are given in the following tables. The resistance factor varies depending on whether the component in question conveys fresh inlet air or hot combustion gases.

The boiler must be installed on a flat vertical wall which is capable of supporting the weight of the boiler. The boiler can be fitted to or adjacent to a wall comprising of a combustible material without the need for a special thermal insulation barrier.

  • Page 12: Central Heating System

    Victrix Zeus 20/27 Instructions Central Heating System The boiler is designed for use in a sealed central heating system. The system should be designed to oper- ate with flow temperatures of up to 80°C. When designing the system, the pump head, expansion vessel size, mean radiator temperature, etc.

  • Page 13: Filling The Central Heating System

    Victrix Zeus 20/27 Instructions The most important components of the system are shown in the diagram below. The cold water supply for the water heating side of the system may come from a booster pump or the • cold water mains where this is permitted by the local authority.

  • Page 14: Domestic Hot Water System

    The installation is subject to Building Regulations and the Water Bye Laws of the Local Authority. The Victrix Zeus 20/27 boiler is supplied with all the components required for a safe and efficient unvented hot water system. An air cushion which is present at the top of the 54l storage vessel provides some of the expansion for the domestic hot water system.
  • Page 15 Victrix Zeus 20/27 Instructions Tundish installation The discharge pipework from the tundish:- 1. Shall fall continuously through its length. 2. Shall be of a heat resistant material, e.g. metal. 3. Shall not be fitted with any valves or taps. 4. Shall discharge to a safe visible position, e.g. onto the surface of an external wall or into a gulley.

  • Page 16: Electrical Safety

    Victrix Zeus 20/27 Instructions Operation and Maintenance Instructions An annual maintenance of the boiler and heating system is recommended. This ensures that the optimal safety, performance and operation characteristics of the boiler remain unchanged over time.
