7.1) INSTRUCTIONS FOR TESTING FOR GAS LEAKS AND PROPER GAS
PRESSURE
TESTING THE INSTALLATION FOR GAS LEAKS:
1. Inspect all connections and appliance valves to be sure connections are wrench-tight and that all
appliance valves are closed, including the pilot valves.
2. Connect a high-pressure test set to the piping system just upstream of the brooder.
3. Fully open slowly the LP gas container valve to pressurize the piping system. Once the system is
pressurized and stabilized, close the container valve tightly.
If the pressure remains unchanged on the gauge for at least 10 minutes, the system can be assumed leak-
tight. If a drop in pressure does occur, it indicates a leak in the system.
If the pressure drop occurs, check the joints, connectors, and other possible points of leakage with an
approved, high quality leak detection solution. NEVER USE A MATCH OR OPEN FLAME TO CHECK FOR
LEAKS. Once a leak has been located and repaired, repeat Steps 3 and 4 above. If there is an increase in
pressure, it indicates that the LP gas container valve is not shut off tightly. Shut off the valve tightly and
repeat Step 4 above.
NOTE: Do not expose final stage piping to excessive heat or direct sunshine during the leak test.
Pressure build-up in the line due to heat may compensate for pressure loss due to leaks. This will prevent
the gauge reading from indicating system leaks.
WARNING: Gas Pressure Testing is to be performed only by qualified personnel.
CHECK GAS INLET (SUPPLY) PRESSURE:
1. Be sure the shut off valve is in the "OFF" position before disconnecting the hose. Connect a suitable high
pressure gauge as shown below at the furthest brooder from the second stage regulator. Turn the shut
off valve to the "ON" position and light the brooders with the thermostat set to the highest temperature
to give maximum gas pressure. DO NOT EXCEED 5 PSI INLET PRESSURE TO THE BROODER.
2. Turn the shut off valve back to the "OFF" position before removing the test set. Repeat the gas leak test.
