Page 14: Piping The Boiler
6. Piping The Boiler All piping must conform to state and local codes. Page 11 shows the location and size of the boiler tappings. It is recommended to install unions and gate valves at the inlet and outlet of the boiler, so it may be readily isolated for service. A low water cut off is required if the boiler is installed above the level of radiation. -
Page 15: Intake Venting
7. Intake Venting 1. Be certain adequate air is available for combustion and ventilation. a.) Boiler located in unconfined space: Installation in large areas, such as basements, can usually be assumed to provide sufficient air. b.) Boiler located in confined space : (See Figure A. on page 14) If all air for combustion and ventilation is to come from within the building: Two (2) openings shall be provided with one (1) opening commencing within 12 inches of the ceiling and one (1) opening commencing within 12 inches of the floor of... - Page 16 7. Intake Venting (Continued...) c.) Boiler located in a room under negative pressure: If the boiler is to be installed within a home where the operation of exhaust fans, attic fans, kitchen ventilation systems, clothes dryers or fireplaces may create severe negative vent pressures causing unsatisfactory combustion and venting, special provisions should be made for additional make-up air to supply the other air requirements.
