GAS CONNECTIONS
1. Gas piping for the house must be sized to be capable of satisfying the entire demands of the
house should all equipment be operating at the same time. Please use Table 1 as a guide
for the sizing of piping for the house. An example using this table is shown.
2. Connect to the supply tank or manifold in accordance with the National Gas Safety
Regulations. Authorities having jurisdiction should be consulted before the installation is
made.
3. Pipe joint compounds must be resistant to the action of
liquefied petroleum (LP) gases.
4. Gas connections to individual brooders can be made in
several ways to fit individual operation practices.
Brooders can be “hard-piped,” or they can utilize
flexible gas connectors, or they can utilize rubber
hosing suitable for LP gas usage (to allow movement of
the brooders for cleaning, etc.). Check with the
authorities having jurisdiction and/or National Gas
Safety Regulations prior to choosing an individual gas
connection method.

5. A field installed keyless manual shut-off valve must be installed in the gas piping to each
brooder. This will allow service of individual brooders without having to shut down the entire
gas supply system. When installing the gas line, it is recommended to connect a sediment
trap (see illustration, previous page) in the gas line at a point before the gas line enters the
house. This trap or “drip leg” acts to trap impurities and water that can condense out of the
gas. It helps to keep impurities from entering the appliance and causing potential damage
to gas valves, etc. Periodically remove the cap from the drip leg and drain any accumulation
of dirt and/or water.
6. After all gas connections and adjustments are made, check all gas connections for leaks
(not just the gas connections at the brooders) using a heavy soap suds solution.

WARNING: DO NOT USE AN OPEN FLAME OF ANY KIND TO TEST FOR LEAKS!
7. It is recommended that a pressure gauge be installed at the end of the gas piping run to
allow you to check the gas supply pressure in the system. This needs to be capable of
accurately measuring in units of inches of water column or mbar.
