NORLAND 1 GENERAL The NORLAND boilers have a horizontal through-flame combustion chamber and a vertical condensing section of a special design, in stainless steel type AISI 316 Ti. These elements are immersed in water contained in a horizontal boiler drum with a vertical column to which the system inlet and outlet connections are fitted.
NORLAND 2 GENERAL WARNINGS Each generator is provided with a data plate that can be found in the envelope with the boiler documents. The plate lists: • Serial number or identification code; • Rated thermal output in kW; • Furnace thermal output in kW; • Types of fuels that can be used; • Max operating pressure. A manufacturer's certificate is also provided which certifies the hydraulic test pressure.

NORLAND 4 INSTALLATION Before connecting the boiler, carry out the following operations: • Clean carefully all the system pipe work to remove any residues that could damage impede correct boiler operation; • Check that the flue has sufficient draught, has no restrictions, is free of all soot and residues, and is perfectly gas tight in particular to the water vapour contained in the flue gas. Check further that no other devices are connected to the flue.
NORLAND 4.4 ELECTRICAL CONNECTION The electrical system in a heating plant that is for building heating only, is the object of numerous regulations, some of which are general in character, others being specific to the type of application or type of fuel. 4.5 CONTROL PANEL The control panel supplied with the boilers is made of self-extinguishing plastic and houses the regulation and safety instruments: Fig. 1 LEGEND 1 2 4 7 8 9 11 PANEL LIVE BURNER SWITCH N.
NORLAND 4.7 INVERTING THE DOOR APERTURE (MOD. 90 - 125) The door can be opened in either direction (RH or LH). For the door height adjustment see Fig. 2. Fig. 2 – Door clamping arm 4.8 INVERTING THE DOOR APERTURE (mod. 160 - 860) If the door is to be opened to the opposite side, act as follows: 1. Switch the outside nut (or bush) of one hinge with the diametrically opposite closure bush; then at the hinge side, fasten the cone to the door with the inside nut. 2.
NORLAND 4.9 PRESSURISED BOILER CONNECTION Before installation, clean the inside of all the fuel supply pipes, to remove any residues that might compromise correct boiler operation. Check the maximum combustion chamber pressure, as shown in the technical characteristics table, the observed value can increase by 20 %.
NORLAND 5 5.1 • • • 5.2 • • • • • FITTING THE BOILER CASING BOILER BODY INSULATION (Fig. 4-5-6) Wrap glass wool (A) around the shell and attach with the clips. Wrap glass wool (B) around the upper cylindrical boiler body without covering the shaft/bulb holder located near the flanged outlet pipe and fix in position with the clips supplied. Then insulate the rear boiler plate, attaching the wool (C) to the springs on the edge of the plate (see figure). BOILER CASING MOD. 90 - 120 (Fig.
NORLAND 5.3 • • • • BOILER CASING mod. 160 - 270 (Fig. 5) Fit the panel (1D) by hooking the upper profile to the square tube and the lower to the boiler longheron. Repeat the same procedure for panel (1S). Fit the panel (2D) by hooking the upper profile to the square section tube and inserting it in the slots in the lower panel.
NORLAND 5.4 • • • • • • • BOILER COVERING model. 350 - 860 (Fig. 6) Mount the panels (1D) fixing the lower folds on to the metal strut on the boiler and attaching the upper ones to the centre with the appropriate screws. Repeat the same procedure for the panels (1S). Mount the panels (2D) fixing the upper folds to the rectangular tube and inserting them into the appropriate slits in the lower panels.
NORLAND 6 STARTING IMPORTANT: before starting insert the flue gas baffles completely in the flue gas pipes, pushing them in by at least 100 mm. 6.
NORLAND 7 7.1 OPERATION OPERATION CHECKS The heating system must be used suitably, ensuring on the one hand, optimum combustion with reduced emission to the atmosphere of carbon monoxide, hydrocarbons and soot, and on the other avoiding all damage to persons and property. The pressurisation must remain within the limit values shown in the technical data table. The burner switch should always remain on; this ensures that the boiler water temperature remains near the value set by the thermostat.
