What must be avoided in cold climates when using single-wall pipe?

In cold climates, the use of single-wall pipe requires careful consideration regarding outdoor venting. Single-wall pipes are not insulated and can lose heat quickly when exposed to cold temperatures. Venting these pipes outdoors in frigid conditions can lead to the condensation of gas within the pipe as it cools down, which could then lead to dripping or pooling of condensate. This creates a potential hazard, as accumulated moisture could cause corrosion or other issues that compromise the integrity and safety of the system. Ensuring that the venting maintains a path with minimal exposure to cold air is important for maintaining the efficiency and safety of the propane system. Proper venting practices help to mitigate risks associated with cold weather.
