A current exception to nfpa this provision allows nfpa elbows with their centerline plane perpendicular to a horizontal split-case pump shaft to be nfpa permitted at any location in the nfpa pump suction intake.
An additional circulation relief valve is required downstream of a pressure relief valve that nfpa is piped back to suction.
While there might be sufficient water flow at these elevated temperatures to sufficiently cool the engine, air inlet temperatures cannot be sufficiently cooled and nfpa can cause the engine to operate outside the range necessary for nfpa EPA compliance.
The revised text better nfpa ensures that no lift or pull occurs between the tank and the suction flange of the fire pump.Unless an arrangement as described by the above new provisions was provided, calibration of the flow meter required physical removal of the device and testing in an arrangement that might not reflect the actual pump and piping installation.The advisory text serves to reduce the amount of water that is needlessly discharged and better aligns with green building design efforts.Acceptance testing: Test duration The standard currently requires that the fire pump be in operation for not less than 1 hour total time during the acceptance tests.This was not the intent and the language was revised to better clarify this.
