DIAGRAMS FOR ROOM AIR VENTING TERMINATION
If you’re using room air, your unit should be set up this way:
NOTE: Stated eciencies are based on ducted air; using room air may eect eciency.
FIGURE 45 VERTICAL TERMINATION
FIGURE 46 SIDEWALL TERMINATION
As long as the boiler room remains under a positive pressure under all operating conditions of the building, this is a
perfectly acceptable option. Generally, all this requires is an external free air source; typically just two properly sized
openings to the outdoors. Installations done in this manner must comply with ANSI Z223.1, NFPA 54—National Fuel Gas
Code 2009 section 9.3, and any specific local codes that may require additional combustion air be provided. For the latest
edition, see Technical Bulletin–TB 003. This would be our preferred alternate to our standard manual specifications.
Flue Gas will condense as it exits the vent
termination. This condensate can freeze
on exterior building surfaces which may
cause discoloration of these surfaces.
Consideration should be given to the plume
of condensation that exits the exhaust
which may aect the cosmetic appearance
of the building.
