Question 71

Condensate drain piping from a condensing boiler should NOT discharge onto a street or an alley.

Discharging condensate drain piping from a condensing boiler onto a street or an alley is improper and can lead to safety hazards and environmental concerns.

A) onto a street or an alley

This option is correct because discharging condensate onto a street or an alley can create slippery surfaces, which poses a safety risk for pedestrians and vehicles. Additionally, it can lead to local drainage issues and potential contamination of stormwater systems.

B) onto a flat roof

Discharging onto a flat roof is generally acceptable as long as the roof is designed to handle the condensate. It allows for proper drainage and evaporation, mitigating any risk of water pooling or structural damage.

C) into a French drain

This option is also acceptable since a French drain is designed to manage excess water. Discharging condensate into a French drain helps ensure proper drainage without creating hazardous conditions.

D) to a grassy area

Discharging condensate to a grassy area is typically permissible, provided the condensate is neutralized and does not harm the vegetation. This method allows for natural absorption and minimizes runoff issues.

Conclusion

The correct answer is option A because allowing condensate to discharge onto streets or alleys creates significant safety hazards and potential environmental issues. In contrast, the other options (B, C, and D) provide adequate methods for managing condensate without posing risks, demonstrating their appropriateness in handling boiler byproducts.
