A drip shall not be located where the condensate is likely to do what?

A drip should not be located where the condensate is likely to freeze because freezing can obstruct the flow of condensate and lead to the formation of blockages in the drainage system. This can result in water accumulating in the system, potentially leading to excessive pressure build-up or even system failures. When condensate is allowed to freeze, it can cause damage to both the piping and the appliance it serves, which can also create hazardous conditions.

Moreover, proper drainage is essential in ensuring that any accumulated condensate is safely disposed of and does not remain within the system longer than necessary. Therefore, placing a drip in an area prone to freezing conditions undermines the operation and safety of gas appliances and their connected systems.
