Nitrogen Oxides (NOx) that form when the flame remains at high temperature in the combustion chamber for long periods. The Norland boilers place no limit on the return water temperature, and reach the highest performance when used with floor panel heating systems in which the return temperature is lower than 58C. At higher tempera- tures, condensation does not occur and so the recovery of the latent heat contained in the water vapour, pre- sent in the flue gas, is impossible. -
Page 4: General Warnings
NORLAND 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;... -

Page 8: Installation
NORLAND 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 per- fectly gas tight in particular to the water vapour contained in the flue gas. -
Page 9: Electrical Connection
NORLAND ELECTRICAL CONNECTION The electrical system in a heating plant that is for building heating only, is the object of numerous regula- tions, some of which are general in character, others being specific to the type of application or type of fuel. -

NORLAND 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 INVERTING THE DOOR APERTURE (mod. 160 - 860) If the door is to be opened to the opposite side, act as follows: 1. -
Page 11: Pressurised Boiler Connection
NORLAND PRESSURISED BOILER CONNECTION Before installation, clean the inside of all the fuel supply pipes, to remove any residues that might compro- mise correct boiler operation. Check the maximum combustion chamber pressure, as shown in the technical characteristics table, the observed value can increase by 20 %. As the fuel used should only be gas,make the following checks: a) check the internal and external fuel supply system for any leaks;... -

Page 13: Boiler Casing Mod. 160 - 270
NORLAND 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 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). -
Page 15: Starting
NORLAND STARTING IMPORTANT: before starting insert the flue gas baffles completely in the flue gas pipes, pushing them in by at least 100 mm. PRELIMINARY CHECKS Before starting the boiler, make sure that: The number plate data corresponds to the electrical, water and liquid or gas fuel supply data;... -
Page 16: Operation
NORLAND 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 dam- age to persons and property. - Page 18 93120032 Ed. 10-05/08 10 - St. 10- 05/08...
