6.5.4 Air Intake and Vent Starter Pieces

Venting must be supported per guidelines listed in the National Mechanical Code, Section 305,
Table 305.4 or as local codes dictate.
Figure 6-2 shows how the air intake and vent outlet adapters are assembled. To connect a vent
pipe to the air intake and vent outlets, proceed as follows while referring to Figures 6-2 and 6-3:
Installing the Air Intake and Vent Connections
1. Apply a suitable sealant (Viton RTV or equivalent) to the inside diameter of both the air inlet
adapter and vent outlet adaptor (see Figure 6-2) to create an airtight seal with the piping.
Install air inlet piping and exhaust vent piping 3" deep into the adapters.
2.
3. Tighten each adaptor hose clamp (Fig. 6-2) to secure each adaptor to its respective piping.
Drill a 1/4" hole into the exhaust outlet piping in approximately the position as shown in
4.
Figure 6-2. This port will be used as a combustion analysis port during the combustion
calibration procedure described in Section 8.2. Procure a suitable cap to plug this port when
it is not being used for calibration.
WARNING!
You must ensure that a suitable cap is used to seal the calibration analysis port during
normal operation to prevent the escape of dangerous exhaust gases.
