WARNING: Improper installation, adjustment, alteration, service or maintenance can cause injury, property
damage or death. Refer to this manual. For assistance or additional information, consult a qualified
installer, service agency or the gas supplier.
INSPECT all combustion air openings into the building and, if necessary, clear as they become blocked by
litter, dust, feathers or other matter.
INSPECT and clean the brooder filters on a regular basis to allow proper brooder operation.
FOR YOUR SAFETY: EXHAUST FANS MUST be operating on an appropriate cycle when brooders are operating
to avoid a high concentration of carbon monoxide. When used without fresh air, this brooder may give off
carbon monoxide, an odorless and poisonous gas. CARBON MONOXIDE POISONING MAY LEAD TO DEATH.
Early signs of carbon monoxide poisoning resemble the flu with headaches, dizziness and nausea. If you
experience these signs, GET FRESH AIR IMMEDIATELY! Have the brooders serviced as soon as possible and
check the ventilation in the house.
These brooders are designed for agricultural applications and may operate with the use of either Natural Gas
or Liquid Propane (LP) Gas. Check the brooder’s nameplate to determine the correct gas type before
proceeding with installation.

1. GENERAL INFORMATION
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.
This brooder is for INDOOR INSTALLATION ONLY and is used in an UNVENTED mode. The term
Unvented actually means Indirect Vented. While the products of combustion are expelled into the
building, national codes require ventilation in the building to dilute these products of combustion.
This ventilation must be provided by gravity or mechanical means. Ventilation requirements are
addressed further in these instructions.
This heater complies with IAS U.S. No. 8-94 (Draft No. 2) and CAN-1-2-20-M85.
Copies of the National Fuel Gas Code (ANSI Z223.1-latest edition) are available from the CSA at
8501 E. Pleasant Valley Rd., Cleveland, OH 44131 or 55 Scarsdale Road, Don Mills, Ontario M3B

6. 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.
FIGURE 5a
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 brooder 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.
WARNING
FIRE HAZARD
A safety chain must be connected from the hanging bracket to a
fixed part of the building structure directly above the brooder.
The safety chain will prevent the brooder from falling to the floor in
the event that the main suspension system fails
Failure to follow these instructions may result in death, serious
injury or property damage

7. 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.
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.
5. Connection to a new installation with accessory hose and fittings is shown below:

Make sure connection is secure before turning on the gas. See section 7a for procedures to test
for gas leaks before putting the brooders into operation.
FIGURE 5c
6. 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
(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.
7. 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 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!
8. 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.
7a. INSTRUCTIONS FOR TESTING FOR GAS LEAKS AND PROPER GAS
PRESSURE
WARNING: D O N OT OMIT THESE TE ST 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 low-pressure test set to the low pressure piping system just upstream of the appliance
regulators and control. NOTE: A dry gauge manometer is available as an accessory (Part No.
43649000).
3. Fully open the LP gas container valve slowly to pressurize the piping system. Once the system is
pressurized and stabilized, close the container valve tightly.
4. Observe the indicated pressure on the low-pressure test set gauge. This reading should be
approximately equivalent to the set delivery pressure of the final stage regulator. Now, slowly
open one burner valve or pilot valve on the appliance to vent off just enough gas to reduce the
pressure on the test gauge by 1” water column, then close the burner or pilot valve.
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

Form No.43539118
May 2013
12
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 valve is in the “OFF” position before removing the pressure tap plug at the valve.
Connect a low-pressure test set (water manometer or dry gauge) to the 1/8” NPT Inlet Pressure
Tap connection. (Refer to Figure 6 for each control valve type.) Turn the valve to the “ON”
position. DO NOT EXCEED THE PRESSURES SHOWN IN THE GAS PRESSURE TABLE.
2. Turn the valve back to the “OFF” position before removing the test set and replacing the plug.
Repeat the gas leak test at the plug
.
CHECK GAS OUTLET (MANIFOLD)
PRESSURE:
1. Be sure that the valve is in the “OFF” position before removing the pressure tap plug at the valve.
With the main burner operating, check the manifold pressure using a lower-pressure test set
connected to the 1/8” NPT Outlet Pressure Tap. (Refer to Figure 6 or 6a for each control valve
type.) Control 2 has combination valves with built-in appliance regulators. These regulators are
factory set and should not require adjustment.They should provide the correct manifold pressure
at the varying supply pressures noted in the Gas Pressure Table below. DO NOT EXCEED THE
PRESSURES SHOWN IN THE GAS PRESSURE TABLE.
2. If manifold gas pressure adjustment is required, remove the cover screw. (See Figure 6 or 6a for
valve drawings.) Using a small screwdriver, turn the adjusting screw clockwise to increase or
counter clockwise to decrease the gas pressure to the burner.
3. Turn the valve back to the “OFF” position before removing the manometer and replacing the
plug. Repeat the gas leak test at the plug.

PRESSURE READING NOTES —CONTROLS 3 AND 9 ONLY:
1. INLET PRESSURE can be checked by turning the captured screw (see Figure 6a) counter
clockwise 2 or 3 turns and then placing the tubing from the gauge over the test point.
2. OUTLET PRESSURE can be checked in the same manner as described above by using the
captured screw.

WARNING:After taking pressure readings, be sure to turn captured screws clockwise firmly to
reseal. Do not over torque. The appliance regulator is not adjustable.
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 12” water column, the maximum allowable lock-up pressure is 14.4” water
column.
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.

7b. 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 Figure 9 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.
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. 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.
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. The brooders with the #3 and #9 control options do not require any electrical supply because
they generate their own electricity and operate thermostatically off this power.
4. Each brooder with the #2 control option requires a 24 volt-power supply via a 24 volt
transformer. The 24 volt transformer MUST be large enough to operate the number of brooders
connected to it (see table below). This is calculated as follows:

An optional Zone Control Power Supply Panel is available as an accessory (Part #43619050) to
provide the required 24VAC for each #2 brooder. The Zone Control comes equipped with a
375VA transformer.
NOTE: If you plan to use the Zone Control with its DC back-up power supply capabilities, special
attention must be given to individual brooder wiring because the DC electrical power is polarity
sensitive. All brooders must be connected the same way (i.e., the same power leg must be
connected to the same terminal on every brooder). While this will not affect brooder operation
on 24VAC, brooders that are not hooked up in this manner will not work properly on DC power.
Refer to Figure 8 for a typical wiring schematic. These #2 control brooders must be supplied
with a thermostat for temperature control (either with or without the Zone Control Panel).
5. A Thermostat (available as an accessory, Part #30525010, or an environmental controller, etc.)
is also required for each brooder or group of brooders as shown in the schematic. The schematic
(Figure 8) 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 Zone Control and
Thermostat.

9. LIGHTING AND SHUTDOWN INSTRUCTIONS
NO. 2 CONTROL (#VR8200M VALVE)
1. Turn gas control knob counterclockwise to “PILOT”.
2. Push and hold down the red reset button while you light the pilot. Immediately
light the pilot with a match. Continue to hold the control/reset button down for
about one (1) minute after the pilot is lit. If it goes out, wait five (5) minutes
before trying to relight the pilot. NOTE: If the reset button does not pop up when
released, stop and immediately call your service technician or gas supplier.
3. If the pilot will not stay lit after several tries, turn the gas control knob clockwise
to “OFF” and call your service technician or gas supplier.
4. When the pilot flame remains lit, turn the gas control knob counterclockwise 
to “ON”.
5. Turn on electrical power supply to the brooder.
6. Adjust the wall-mounted thermostat to change the temperature setting. Adjust
as desired for bird comfort.
7. NOTE: To turn off the main burner only, turn the gas control knob clockwise to
“PILOT”. For complete shutdown, turn the gas control knob clockwise to
“OFF”.
NO. 3 AND NO. 9 CONTROLS (#0630501 VALVE)
1. Turn the gas cock dial on the control valve to the “PILOT” position. Depress the
dial and apply lighted taper to the pilot burner.
2. Hold the dial in for one (1) minute after the pilot is lit. Release the dial. If pilot
flame fails to establish, repeat the procedure.
3. If pilot flame fails to establish after a second attempt, refer to the fault-finding
chart.
4. When the pilot flame is established, turn the gas cock dial to the “ON” position
and set the thermostat to call for heat. The main burner will ignite.
5. Adjust the remote thermostat to change the temperature setting. Adjust as
desired for bird comfort.
NOTE: TO TURN OFF THE MAIN BURNER only, turn the gas cock dial to the “PILOT”
position. FOR COMPLETE SHUTDOWN of main burner and pilot, press in the gas
cock dial and turn to the “OFF” position.
6. If the brooder is to be taken down for inspection or maintenance, turn the
ON/OFF ball valve on the connecting kit hose to the “OFF” position and
disconnect the hose from the control valve inlet.

10. VENTILATION
FOR YOUR SAFETY: Exhaust fans must be operating on an appropriate cycle when heating the
building to avoid high concentrations of carbon monoxide and water vapor.
The temptation, particularly during the winter months, is to close up the poultry house to conserve
heat and save money. This must be resisted, particularly during the heating up period prior to the
arrival of the stock, because the lack of ventilation can restrict the required amount of combustion
air for the brooders causing them to burn improperly and produce levels of carbon monoxide which
could be harmful to people and the stock.
WARNING: Carbon Monoxide is an odorless and poisonous gas. Extended exposure to carbon
monoxide may lead to death. Early signs of carbon monoxide poisoning resemble the flu, including
headaches, dizziness and/or nausea. If you experience these signs, GE T FR ESH AIR
IMMEDIATELY. Have the brooders serviced as soon as possible and check the ventilation in the
house.
The National Fuel Gas Code requires a minimum of 4 CFM per 1000 Btu/hr of brooder input for
ventilation. This requirement means that a total of 160 CFM is required per brooder. Ventilation
requirements may vary depending on other equipment that may be located in the building requiring
ventilation. All ventilation requirements should be addressed before sizing the necessary gravity or
mechanical means to accomplish this ventilation.
While ventilation is necessary for proper brooder operation and proper growing conditions for the
stock, excessive ventilation can result in high fuel consumption. Adjust the ventilation as necessary
for optimum performance of the brooders and growing conditions for the stock.
