4. Installation 7-2018

NOTICE

Follow any local codes and standards, as they may require a different

method or documentation of a leak test.

Perform the following fuel piping system leak check:

1. After assembly and before initial operation of generator set, test all fuel system

components as required per the National Fuel Gas Code (NFPA 54).

2. The National Fuel Gas Code requires that the generator set be isolated from

the piping system by disconnecting it and capping the outlet prior to test. The

test pressure required is the greater of 1.5 times the supply pressure or 3 psi

(20.7 kPa) minimum.

3. After successfully completing the previous step, connect the generator set to

the fuel piping system.

4. To verify that all connections from the fuel piping system to the generator set

are free of leaks, conduct a bubble test using an approved leak detection

solution (or equivalent method) with the system pressure of 0.8 to 1.0 psi (5.5 to

7.0 kPa).

5. Spray the bubble solution on all of the joints.

6. Inspect all of the joints and monitor the line pressure. If bubbles appear, there is

a leak.

7. If any leaks are found, repair the joint or replace components as needed.

8. Verify the leak has been fixed.

NOTICE

The leak detection solution (that is, bubble solution) must be non-corrosive

and be free of ammonia and chlorine.

4.3 Engine Exhaust

The exhaust system for this generator set is complete and was designed specifically

for this generator set. Do not modify or add to the exhaust system of this generator

set.

WARNING

Exhaust gas is deadly. Make sure that the exhaust system terminates away

from building vents, windows, doors, and sheltered spaces that may not

have ample fresh air ventilation.

WARNING

Engine discharge air and exhaust carry carbon monoxide gas (odorless and

invisible) which can cause asphyxiation and death. Never use engine

discharge air or exhaust for heating a room or enclosed space.
