M2 Exam Dumps - Commercial Mechanical Inspector

The IFGC definition of fuel gas is: natural gas, manufactured gas, liquefied petroleum gas or mixtures of these gases . That definition directly matches Option B .

In the IMC hydronic piping provisions for ground-source heat pump loop systems, shutoff valves are required on both sides of a pressure-reducing valve . That matches D . Heat-fusion joints and change-in-material joints do not trigger this two-sided shutoff-valve requirement.

Solid-fuel cooking equipment requires a separate hood and exhaust system . It is not permitted to share the same hood/exhaust arrangement in the manner suggested by the other choices. This is a standard commercial kitchen exhaust requirement because of the added fire and residue hazards associated with solid-fuel appliances.

Based on the specification sheet shown in the exhibit, the design features state that the optional integral clearance reduction system meets the requirements of NFPA 96 . Therefore, the correct answer is D .

For cooking equipment with exposed flame and burners , the IMC table for grease-filter mounting position requires a minimum vertical separation of 24 inches between the lowest edge of the grease filter and the cooking surface. That makes B correct.

For commercial kitchen exhaust associated with Type I hood systems, the recognized code-based minimum duct transport velocity is 1,500 feet per minute , so C is the correct answer. Option B uses the wrong unit, and the other listed velocities do not match the code minimum used for this question type.

The IMC requires fuel-burning units to be marked with the hourly rating, approved fuel type, and required clearances . That means the appliance marking/nameplate is the direct source for the required clearance information for listed fuel-burning appliances. This is why B is the correct answer.
