This brooder is a self-contained infrared radiant brooder for agricultural locations where flammable gases or
vapors are not generally present.
Installation of the brooders must be in accordance with all applicable codes shown in the instructions and/or
the local codes and authorities having jurisdiction. In the absence of local codes, the brooder must be
installed in accordance to the National Fuel Gas Code ANSI Z223.1/NFPA54 in the U.S. or the CAN/CGA-
B149.1/2 Installation Code in Canada. Clearances to combustibles as outlined in the manual should always
be observed.
Inspect all openings and filters regularly and clean as necessary. This is necessary because litter, dust
feathers and other matter can become airborne and clog openings and filters and adversely affect brooder
operation and performance.
Every brooder should be located with respect to building construction and other equipment so as to permit
access to the brooders. Each installer shall use skillful and reliable installation practices when locating the
brooders and must give consideration to service accessibility.

6.0) BROODER INSTALLATION
1. Locate brooders approximately 25’ to 40’ (8m to 12m) apart, in a row, as needed for bird comfort and
building heat loss. If more than one row is desired, stagger rows for best heat distribution. Attach the
Chain Kit (optional) to the top of the brooder Canopy. NOTE: Make sure that the large hook (short chain
length) is secured to the hanging lug on the side of the brooder closest to the gas valve.
2. Suspend the brooder at the desired height above the floor (litter) level, normally 60” to 72” (1520mm to
1830mm). For brooders connected to a winch (to allow for adjustment of brooder height), connect each
Chain Kit using a chain or cable suitable for the weight of each brooder. DO NOT USE ROPE.Size the
winch and cable so that it is capable of handling the total weight of all brooders and gas piping involved.
NOTE: Connect a safety chain to each brooder and anchor it to the house structure above each brooder
to prevent it from falling onto the litter if the cable/chain breaks or the winch fails. THE GAS HOSE
SHOULD NEVER BE USED AS A SAFETY CHAIN!
3. Connect the gas line and electrical supply (if required) to each brooder as outlined in Sections 7 and 8.
NOTE: After connection of the gas line, make sure that the brooder is suspended with the control side
approximately ½” (13mm) below the other side of the brooder to prevent hot products of combustion
from damaging the gas control valve.

Form No. 43539510

7.0) 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 (taken from the National Fuel
Gas Code) 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 latest edition of the National Fuel Gas
Code (ANSI Z223.1) and/or local codes. Authorities having jurisdiction should be consulted before the
installation is made. Refer to the latest edition of CAN/CGA B.149-1/2 Installation Codes for Gas
Burning Appliances and Equipment in Canada.
3. Pipe joint compounds must be resistant to the action of liquefied petroleum (LP) gases.

Form No. 43539510
May 2020 –13–
4. Gas connections to individual brooders shall be made using 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 local codes prior to choosing an individual gas connection
method.

Make sure connection is secure before turning on the gas. See section 7.1) for procedures to test for gas
leaks before putting the brooders into operation.

Form No. 43539510
–14–May 2020
6. Suspend the gas hose line to the ceiling structure using safety cable. This will reduce the potential that
the hose can touch the canopy when the brooder is lowered or raised.
7. It is strongly recommended that a field installed manual shut-off valve 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 (shown
below) 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.
8. 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 soapsuds solution or by using one of the methods listed in
Appendix D of the National Fuel Gas Code. WARNING: DO NOT USE AN OPEN FLAME OF ANY KIND TO
TEST FOR LEAKS!
9. 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.

7.1) INSTRUCTIONS FOR TESTING FOR GAS LEAKS AND PROPER GAS
PRESSURE
W A RNIN G : D O NO T O MI T T HE SE T E S T S !
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.

REGULATOR LOCK-UP AND LEAKAGE:
After the leak testing and delivery pressure tests have proven satisfactory, the regulator lock-up and leakage
test may be performed. The lock-up pressure of the final stage regulator should be slightly higher than, but
not more than, 120% of the set delivery pressure. For example, on a delivery pressure setting of 5 PSIG, the
maximum allowable lock-up pressure is 6 PSIG.
To perform the lock-up and leakage test, follow these steps:
1. With the LP tank valve fully open, shut off all appliance valves so there is no demand for gas. This
includes shutting off all pilots.
2. A slight rise in pressure will occur under these conditions. This rise should be no more than 120% of the
delivery pressure. This is the lock up pressure. NOTE:A quick rise in pressure above the allowable lock-
up point could indicate undersized piping, a worn seat disc or foreign material in the seating area. This
condition must be corrected before putting the system in service.
3. Continue the test for five minutes or more. If a creeping rise in pressure is noticed, the final stage
regulator seat is not closing off properly. The regulator must be replaced or repaired, and the system
retested, before putting the system in service.
7.2) GAS PIPE SIZING EXAMPLE
House Size: 40’ x 400’
Brooder Quantity: 14
Individual Brooder Capacity: 40,000 Btu/hr
Second Stage Regulator Pressure: 14” W.C.
Operating Pressure: 11”W.C., LP gas with all brooders operating
STEP 1.Gas should be run at high pressure from the LP tank to the second stage regulator at the house.
Using the above house configuration example, calculate the gas pipe sizing. First, calculate the total distance
from the second stage regulator to the furthest brooder. In the figure above, that distance equals 202’ (20’ +
182’). Using Table 1, look up the row for 200’ and select the smallest pipe size that has the capacity for the
flow of the end brooder (40,000). The smallest pipe size is ½” with a capacity of up to 58,000 Btu/hr over
200’.
STEP 2.Calculate the distance from the second furthest brooder to the secondary regulator. In the example,
that distance equals 174’. Using Table 1, look up the row for 174’. As 174’ is not listed, you will use the next
distance up, in this case, 200’. Then select the smallest pipe size that has the capacity for the flow of both
the furthest (#7) and second furthest (#6) brooders, which combines to 80,000 Btu/hr. The smallest pipe
size is ¾” with a capacity of up to 120,000 Btu/hr over 200’. Repeat this process for each brooder until you
reach the Tee. Table 2 shows the completed example.

Form No. 43539510
May 2020 –17–
STEP 3.At the Tee, calculate the total distance to the secondary regulator. In this example, that equals 20’.
Using Table 1, look up the row for 20’ and select he smallest pipe size that has the capacity for the flow of all
the brooders connected to the pipe system (560,000). The smallest pipe size is 1” with a capacity of up to
788,0000 Btu/hr over 20’.

Note 1: The distance used is rounded down to 60.
Note 2: The actual smallest pipe size for the required capacity is ¾” from the table. However, the gas pipe size from brooders 3 and 4
to the regulator must be 1” diameter and therefore a smaller diameter pipe cannot be used. If ¾” pipe was used from the Tee to
brooder 1, the pressure drop in the rest of the system would exceed the design pressure drop of ½”W.C.

8.0) ELECTRICAL CONNECTIONS
1. All electrical wiring shall conform to the latest edition of the National Electrical Code (ANSI/NFPA No.
70), or the code legally authorized in the locality where the installation is made. DO NOT use phone cable
for electric supply wiring.
2. The electrical system must be electrically grounded in accordance with the National Electrical Code
(ANSI/NFPA No. 70 - latest edition) or the Canadian Electrical Code (C22.1 Part 1 - latest edition) as
appropriate.
3. Each brooder requires a 120 volt - power supply
4. A Thermostat (available as an accessory, Part No. 30525010, or an environmental controller, etc.) is also
required for each brooder or group of brooders as shown in the schematic. The schematic below shows a
group of four (4) brooders controlled by one (1) thermostat. Additional zone groups having more or less
brooders can be added. These should be wired the same as shown in the schematic.
Contact the factory for pricing and availability for the Thermostat.
