Red Seal Gasfitter — Class A Practice Exam

What is a manifold in the context of gasfitting?

1. A device that measures gas pressure

2. A system of pipes and valves that distribute gas to multiple appliances

3. A safety device to prevent gas leaks

4. A connector for gas hoses

The correct answer is: A system of pipes and valves that distribute gas to multiple appliances

The term "manifold" in the context of gasfitting refers to a system of pipes and valves that distributes gas to multiple appliances. This setup is essential in ensuring that gas can be effectively and safely channeled to various points of use within a gas system. Manifolds serve as a control point in a gas distribution system, allowing for the management of gas flow to different appliances, while also providing a means to isolate portions of the system for maintenance or emergencies. This control is vital to ensure that each appliance receives the appropriate amount of gas for its operation, promoting efficiency and safety. The other choices refer to different aspects of gasfitting. A device that measures gas pressure is crucial for monitoring system performance but does not encompass the broader distribution function of a manifold. A safety device to prevent gas leaks is critical for safety and system integrity, however, it is not a manifold. Similarly, connectors for gas hoses facilitate connections but do not define the manifold's role in gas distribution to multiple appliances. Thus, the manifold is specifically characterized by its function of distributing gas effectively within a gas system.
