The Lochinvar EcoShield can be used as a type C or C appliance.
GAS SUPPLY The Lochinvar EcoShield range is suitable for use on second and third family gasses 2H - G20 - 20mbar and 3P - G31 - 37mbar. Details relating to Natural Gas (2H) appear below; for details relating to Propane (3P) please refer to Section 14 LPG FUEL.
7.6 EQUIPMENT GAS SYSTEM LEAK CHECK An approved gas-inlet appliance isolating valve and union should be installed for each unit in a convenient and safe position and be clearly marked. Ensure that the gas-inlet appliance isolating valve is in the OFF position. Although the equipment receives a gas leak check and gas train component integrity check prior to leaving the factory, transit and installation may cause disturbance to unions, fittings and components.
When used as a Type C (balanced flue) appliance, the approved, purpose designed adaptive flue system should be used. For further details, please contact Lochinvar Limited. When used as a Type B (conventional flue) appliance, a suitable flue system constructed of Stainless Steel or Polypropylene with a temperature rating in excess of 120C should be used.
To install the flue connection to the SHW45-325CE & SHW60-325CE water heaters the following procedure should be followed: Insert the exhaust transition (Item 7 in Figure 8.2) into the exhaust port on the heater. Insert the flue temperature sensor (supplied with the water heater) into the location hole on the exhaust transition.
When the heater is installed as a Type B23 appliance, the flue system should be installed in accordance with the flue manufacturer’s specific instructions. A kit of components to facilitate conventional fluing of the appliance is available from Lochinvar Limited.
Insert the exhaust transition into the exhaust port of the heater. Insert the flue temperature sensor into the location hole on the exhaust transition. NOTE: IF THE FLUE TEMPERATURE SENSOR IS NOT FITTED, THE FLUE GAS MAY EXCEED THE MAXIMUM TEMPERATURE RATING OF THE FLUE AND CAN LEAD TO SEVERE PERSONAL INJURY, DEATH OR SUBSTANTIAL PROPERTY DAMAGE.
Fit the support bracket around the terminal and secure using appropriate fixings. Do not tighten the support bracket Install the remainder of the flue system working progressively away from the water heater supporting the pipes as necessary. Once the flue system is fully installed, tighten the clamp to secure the terminal in place. FIGURE 8.7 VERTICAL TERMINAL ROOF FLASHINGS FOR SYNTHETIC, FLAT AND TILED ROOFS FIGURE 8.8...
If a horizontal flue terminal is to be fitted less than 2 metres from ground level or in a location where it can be touched from a window, door or balcony, a terminal guard must be fitted. An approved terminal guard, Lochinvar Part No.
INSTALLED BY AN APPROVED INSTALLER. If the Lochinvar EcoShield is to be used in an unvented arrangement, the system should follow the guidance given in BS6700 and must comply with the Building Regulations 1992: Part G3. A kit of components that have been suitably sized for the unvented operation of the appliance is available from Lochinvar Limited.
10.3.2 RELIEF VALVE DISCHARGE PIPEWORK It is important that any discharge water does not collect in the discharge pipe-work and can run freely to the tundish. The Tundish should be mounted in a vertical and visible position located in the same space as the unvented hot water storage system and be fitted as close as possible and within 500mm of the safety device e.g.

should be interrupted using a suitable relay. The burner control interprets the break in the wiring as a very high temperature within the storage vessel and shuts the burner down if it is firing or prevents a firing sequence occurring if it is not. It should be noted that the design of the control board interprets the very high recorded temperature as a fault and automatically closes the alarm contacts to indicate that an error has occurred;...
