Revision of existing heating system piping may be appropriate to properly utilize the equip- ment. Although Tarm Biomass can provide advice and design detail on the integration of this boiler with the heating system of the building, the ultimate responsibility for the performance of the system rests with the installer. -
Page 14: Boiler Installation And Start-Up
It is critical to size the boiler properly. A proper, up to date heat load calculation is advised. An accu- rate history of building fuel usage over several years can help to calculate the proper size boiler. Boiler sizing is the responsibility of the installer. Tarm Biomass bears no responsibility for boiler sizing, but can provide sizing input. - Page 15 D-Minimum Clearance to Combustibles Inches E-Minimum Clearance to Combustibles Inches F-Minimum Distance for Combustibles to Pipe Inches G-Maximum Distance for Flue Pipe Feet H-Ideal Location for Draft Regulator (Barometric Damper) Bonus Plus Instructions Tarm Biomass 1-800-782-9927 Version 11/14 Page 15...

CAUTION ☼ Any plastic or rubber tubing used with a Tarm Biomass boiler must have an oxygen barrier, or boiler corrosion will occur. If radiant tubing without an oxygen barrier is installed, water in the tubing part of the heating system must be separated from the boiler. Separation of system com- ponents is typically done by using a heat exchanger. -
