At what upward pitch should vent connectors be installed?

The correct answer is a pitch of 1/4 foot for vent connectors. This pitch is essential for allowing proper drainage of condensate back toward the appliance rather than accumulating within the vent. A 1/4 inch per foot slope helps ensure that any moisture or condensate produced during combustion can flow back into the appliance's drain system and not create blockages or reduce the efficiency of the venting system.

Proper vent connector sloping is vital for the safe and efficient operation of gas appliances. It minimizes the risk of corrosion and deterioration that can occur if condensate accumulates in the venting system. Ensuring this specific pitch aligns with industry standards and codes designed to promote safety and reliability in gas ventilation systems.

Options suggesting a pitch greater or lesser than 1/4 foot do not support the optimal functioning of vent connectors, as they either risk improper drainage (if shallower) or create potential issues with gas flow and condensate management (if steeper).
