Page 6: Boiler Room Design
The boiler room for biomass boilers must be installed in accordance with the rules set forth by your local building codes, environmental authorities, and labor inspectorate. If you are in doubt on how to set up your boiler room, we recommend that you contact your local certified RTB dealer for guidance. 1. Wall and Ceiling 2. - Page 7 Boiler Room Design The internal diameter of the chimney must be sufficient enough for the amount of flue gases the chimney has to lead away. If the internal diameter is too small, this will prevent the smoke from exiting fast enough due to the large resistance in the chimney. This could cause the smoke to turn back; thus allowing for toxic fumes to enter into the house.
- Page 8 Boiler Room Design 8. Wood pellet The pellets must be pure wood, 6-8 mm Max 8% water. Materials with glue, paint, wood paint or plastics shall not be burned. If the fuel storage is greater than 0.75 m3, the boiler system and fuel storage must be located in a separate fire cell with at least one BD30 door to the other room.
