Correct boiler venting is crucial for proper operation. Being a condensing boiler, combustion gases
are discharged at a very low temperature. It is therefore necessary for the venting system to be
impermeable to combustion products and condensate and to be made of corrosion resistant
materials. Typical Category IV venting and sealed combustion illustrations are shown in Figures 5
and 6. The various funnel joints shall be well sealed and/or equipped with suitable gaskets, in order
to avoid any condensate drain and/or air intake. Ensure that the boiler vent's section and height
conform to national and local regulations (see Section 1.1 in this guide).
For boilers designed for connection to gas vents or chimneys, vent installations shall be in
accordance with Part 7, Venting of Equipment, of the National Fuel Gas Code, ANSI Z223.1, or
Section 7, Venting Systems and Air Supply for Appliances, of the CAN/CGA B149, Installation
Codes, or applicable provisions of the local building codes.
The vent system for the AM Series must be installed in accordance with AERCO's installation
instructions described in this guide.
For Category IV Boilers, the vents must be installed to prevent
accumulation of condensate, and have means provided for drainage of
condensate.
3.1. VENT INSTALLATION
•
The boilers covered in this section are design-certified as Category IV for venting, only when
they are installed with manufacturer specified vent system components and installation
practices.
•
Install supplied vent pipe starter piece at the boiler vent connector and work toward the vent
cap.
•
Vent pipe fittings and connectors serving appliances vented by natural draft shall not be
connected into any portion of mechanical draft systems operating under positive pressure.
•
Horizontal
runs
(21 mm/m) from the boiler to the vent termination.
•
Horizontal portions of the venting system shall be supported to prevent dips or sags where
condensate could collect.
•
Rigidly support vent pipe every 5 feet and at the elbows. Plumber straps may be used.
•
ALL vent pipe and fittings must be installed with appropriate air space clearances to
combustibles. These air space clearances apply to indoor or outdoor vents, whether they are
open, enclosed, horizontal or vertical or pass through floors, walls, roofs, or framed spaces.
The appropriate air space clearances should be observed between joists, studs, sub floors,
plywood, drywall, or plaster enclosures, insulated sheathing, rafters, roofing, and any other
combustible material. The minimum air space clearance also applies to electrical wires and
any kind of building insulation. For horizontal runs, keep 4 inch and 6 inch vent piping from
any contact with any combustible material, electric wires, and building materials.
