Venting Requirements; Natural Draft Applications - PENSOTTI DK2-3 User Manual

VENTING REQUIREMENTS

All venting of the Quatech Series Boilers shall be done in accordance with national, state, and local
codes, and be in conformity with NFPA 31. In addition design of the chimney connectors,
chimneys, power venting systems and direct vent systems should also conform to State and local
codes and be in accordance with good and accepted industry practice. NFPA 211 should be used in
lieu of local codes.

Natural Draft Applications

Specific guidelines should be followed to prevent the occurrence of the following conditions:
- Condensation of flue gasses.
- Positive outlet draft conditions
- Reverse flow of flue gas during or after burner shutdown.
Chimney Connection
To insure safe and efficient boiler operation flue gasses must be released through a clean, properly
sized chimney with adequate draft that meets all local codes and regulations and be in accordance
with NFPA 211 and NFPA 31. Always inspect and clean the chimney to insure that it is free from
obstructions. The boiler must be connected to an independent chimney flue and not with a shared
flue pipe. Never connect the boiler to a chimney or liner serving an open fireplace. Adjustable
dampers in the chimney or flue pipe should never be used.

CAUTION
Oil fired units must always be connected to flues with proper draft.
