Conventional Chimney Venting & Clv System Application Requirements - DeDietrich C230 ECO-A 120 Installation, Operating And Service Manual

C230 ECO-A 7 Flue gas discharge and air supply
Air supply structure
The air supply pipe must also be airtight. Horizontal sections in the air
supply must slope away from the boiler towards the supply opening
and incorporate a drain connection if the route rises from a lower
point. It is necessary to provide an easily removable air vent for
maintenance reasons.
7.1.5 Conventional Chimney Venting & CLV system
Application Requirements
The boiler should never be operated in a negative building pressure.
Caution should be exercised with exhaust fans, air handling & other
devices, that could affect the buildings air pressure or combustion air
supply. All venting must be arranged to avoid and prevent the
accumulation of flue gas condensation. Where necessary, have
means provided for drainage of condensate.
An improperly sealed venting system could result in carbon monoxide
poisoning; ensure adequate support and fastening of the system.
Ensure venting can safely exhaust all flue gases to the outside in a
safe and effective manner. Do not puncture or drill holes in any portion
of the venting, the boiler is equipped with a pressure and emission
test port.
Precautions for Co-venting
Only co-vent this boiler with another, category II or IV, appliance.
When co-venting the C230 ECO-A boiler a vent damper is required.
Co-venting with other appliances shall conform and be sized in
accordance to local and national codes [CSA B149 & ANSI Z223.1]
according to appropriate tables in Part II of the above mentioned
codes.
Venting lengths must not exceed the minimum and maximum
equivalent lengths shown in the following two tables. Any horizontal
runs of the venting must slope towards the boiler ½" per linear foot.
