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 the relevant provisions of any National
Gas Safety (Installation and Use) Regulations taking into account any National Health and Safety
at Work Regulations, National and Local Building Regulations and National Electrical Wiring
Regulations.
Inspect all openings 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.
For optimum temperature control for brooders requiring remote temperature controls, do not
locate thermostats in shaded or draughty locations, outside the area to be heated. The sensor
should also be shielded from direct radiation to prevent short cycling of the brooder.
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 standards 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.
These instructions are only valid if the following country code is on the appliance GB or IE. If
this code is not present on the appliance, it is necessary to refer to the technical instructions
which will provide the necessary information concerning the modification of the appliance to
the conditions of use for the country.
Before installation, check that the local distribution conditions, nature of gas and
pressure and adjustment of the appliance are compatible.
In the UK, Installation practices must take into account the Health and Safety at Works Act
1974 or relevant codes of practice. In addition the installation must be carried out in
accordance with the current IEE wiring regulations (BS 7671:2001), BS 6896:2005 (Industrial
& Commercial) and any other relevant British Standards and Codes of Practice by a qualified
installer. All external wiring MUST comply with the current IEE wiring regulations.

6. BROODER INSTALLATION
1. Locate brooders approximately 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 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 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 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.
FIGURE 5b
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.

8. Space-Ray recommends that the hose is installed with a spring (item 4) shown below to
keep the hose vertical directly above the canopy. If the brooder is raised and lowered
during operation it is the installer’s responsibility to ensure that the hose cannot come into
contact with the canopy.

7a. INSTRUCTIONS FOR TESTING FOR GAS LEAKS AND PROPER GAS
PRESSURE
▲WA RN I NG : D O N OT O MI T T HE SE 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.
3. Fully open the LP gas container valve slowly to pressurise the piping system. Once the
system is pressurised and stabilised, 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 2.5 mbar, 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 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
FIGURE 6
Control No.2 / No.4

Form 43539178
Oct 2019
11
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 Outlet Pressure Tap. (Refer to Figure 6 or 6a for each control valve
type.) The controls have 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 manifold pressure adjustment
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. Once adjusted replace the manifold pressure adjustment cover screw and seal
using a paint mark.
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:
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 30mbar, the maximum allowable lock-up pressure is 36mbar.

Form 43539178
Oct 2019
12
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: 12.2m x 122m
Brooder Quantity: 14
Individual Brooder Capacity: 12kW
Second Stage Regulator Pressure: 37mbar
Operating Pressure: 25mbar, 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 62m (6m + 56m). Using Table 1, look up the row for 61.5m and
select the smallest pipe size that has the capacity for the flow of the end brooder (12kW). The
smallest pipe size is ½” with a capacity of up to 17kW over 61.5m.
STEP 2. Calculate the distance from the second furthest brooder to the secondary regulator. In
the example, that distance equals 53.5m. Using Table 1, look up the row for 53.5m. As 53.5m
is not listed, you will use the next distance up, in this case 61.5m. 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 23.4kW. The smallest pipe size is ¾” with a capacity of up to 35.2kW over
61.5m. 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 6m. Using Table 1, look up the row for 6m and select the smallest pipe size that has the
capacity for the flow of all the brooders connected to the pipe system (164kW). The smallest
pipe size is 1” with a capacity of up to 231kW over 6m.

Note 1: The distance used is rounded down to 18.5 (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
1.25mbar.
8. ELECTRICAL CONNECTIONS –No. 2 and No. 4 Control
1. All electrical wiring to this brooder must be installed in accordance with the latest or current
National Regulations and any Local Regulations, which apply.
2. The electrical system must be electrically grounded in accordance with the latest or current
National Regulations and any Local Regulations, which apply.
3. The brooders with the #9 control options do not require any electrical supply because they
generate their own electricity and operate thermostatically off this power. The brooders with
the #2 control option require a 24VAC supply to each brooder. This is provided via a 24Volt
Transformer. The 24Volt Transformer MUST be large enough to operate the number of
brooders connected to it (see table below). This is calculated as follows:

4. The wire to the #2 type brooders MUST be a minimum 2.5mm2.
5. Failure to connect the #2 type brooders to the minimum power supply recommended or to
use a cable less than the minimum size specified will result in the brooder not functioning
properly.
6. A Thermostat 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.

9a. COMMISSIONING

It is essential that all new pipework installations are purged and tested for sounding using a
suitable leak detection fluid prior to attempting to ignite any appliance. This work should be
carried out in accordance with National or Local Regulations. DO NOT TEST FOR
SOUNDNESS BY USE OF NAKED FLAMES. Refer to Section 9b for proper Lighting and
Shutdown Instructions.

9b. LIGHTING AND SHUTDOWN INSTRUCTIONS
♦No. 2 CONTROL (#VS8600B-1006 VALVE) and No. 4 CONTROL (4600A VALVE)
1. Depress gas control knob and hold it down
2. Ignite pilot burner. Hold down the knob for 20 seconds after the pilot burner has been lit.
Release knob. If it goes out, wait three (3) minutes before trying to relight the pilot.
3. If the pilot will not stay lit after several tries, release the gas control knob and call your
service technician or gas supplier.
4. When the pilot flame remains lit, release the gas control knob.
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 interrupt the gas flow, the gas control knob must be turned clockwise to its stop.
After release, the knob will automatically rotate to its ready position. A safety devise
prevents the knob from being fully depressed until the thermocouple has cooled down
sufficiently to de-energize the power unit, after which the knob will be effective again. When
the knob is depressed during latch position, pilot gas will flow to pilot burner
♦No. 9 CONTROLS (#0630097 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

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 vapour.
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 odourless 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 FRESH AI R
IMMEDIATELY. Have the brooders serviced as soon as possible and check the ventilation in
the house.
The ventilation requirements and calculation methods for unflued appliances are set out in the
European Standards EN 13410:latest revision and must be applied. Ventilation may be achieved
by any of the three following different means:
a). Ventilation by thermal evacuation.
Ventilation by thermal evacuation is sufficient if 10m3/h of exhaust air per kW of
operating heat input are ventilated out of the installation room.
The air/products of combustion mixture must be evacuated above the radiant heaters, if
possible near the ridge, by means of exhaust mixture openings (vents).
Where the exhaust mixture openings can be closed, it shall only be possible to operate
the radiant heaters when they are open.
The maximum horizontal distance between a radiant heater and vent opening shall be:
6 (six) times the vent height in the case of wall openings
3 (three) times the vent height in the case of roof openings.
b). Ventilation by mechanical evacuation.
Ventilation by mechanical ventilation is sufficient if 10m3/h of exhaust air per kW of
operating heat input are ventilated out of the installation room.
The air/products of combustion mixture must be evacuated above the radiant heaters
using fans.
It shall only be possible to operate the radiant heaters whilst the exhaust airflow is
proven.
The maximum horizontal distance between a radiant heater and a fan shall be:
6 (six) times the fan mounting height in the case of wall openings
3 (three) times the fan mounting height in the case of roof openings.
Total minimum proven ventilation airflow in m3/h will be:
Total installed kW input X 10
Note: Mechanical exhaust air openings must be positioned such that the burner
stability of the nearest appliance us unaffected.

Form 43539178
Oct 2019
17
c). Ventilation by natural air change.
Gas fired radiant heaters may be operated without any special exhaust system if the
exhaust gases are discharged to the outside atmosphere by a sufficient natural air
change in the installation room.
Furthermore, no provision for thermal or mechanical ventilation is required in the
following particular cases:
i). Buildings with natural air change greater than 1.5 volumes per hour
ii). Buildings with a density of operating heat input not greater than 5W/m3.
Air Supply.
Air supply openings are required to admit air and shall be located below the radiant heaters.
The total area of the unobstructed cross-sections of all the air supply openings shall not be
smaller than the total area of the unobstructed cross-sections of all the exhaust openings.
Slits and gaps of fixed cross-sections can also be used as air supply openings.
Where the air supply openings can be closed, it shall only be possible to operate the radiant
heaters when they are opened.
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.

11. SERVICING and MAINTENANCE
CAUTION: Turn the gas and electrical supply OFF and allow the brooder to cool down for
20 minutes before attempting any maintenance.
MAINTENANCE: Maintenance is defined as work that a non-gas competent person may
carry out on the appliance. This work must not involve the use of tools
to maintain/access the gas and electric components on the appliance.
The maintenance procedure must be carried out after each crop.
1. Release the main burner orifice fitting and pan from the burner by turning the swivel clamp.
CAUTION: In order to prevent damage to the control arm tubing, first place a hand under the
pan and allow the control to be lowered gently under its own weight.
2. The orifice must be cleaned without being removed from the fitting. This is carried out by
inserting a pin having a smaller diameter than the actual orifice hole size (see the brooder
nameplate or instruction manual). DO NOT USE A DRILL as this will increase the orifice hole
and result in overfiring.
3. Clean around the burner cap ports with a bristle brush. After cleaning the burner ports,
compressed air can be blown into the burner ports to blow any debris out of the burner
through the burner venturi.
4. Clean both the inside and outside surfaces of the perforated emitter assembly with a large
wire brush; then use compressed air to remove any burnt dust or dirt particles from the
emitter.
5. Reconnect the main burner orifice fitting and pan to burner in reverse order.
6. Remove the windshield and housing tab. The pilot orifice must be cleaned without being
removed from the fitting. This is carried out by inserting a pin having a smaller diameter than
the actual orifice hole size (see the brooder instruction manual). DO NOT USE A DRILL as
this will increase the orifice hole and result in overfiring.
7. Replace the housing tab and windshield.

SERVICING:A qualified person must service the appliance. Servicing is defined as work that
requires the use of tools or the person to access/remove components along the
control arm assembly. The brooder must be serviced annually as a minimum,
or more frequently as circumstances/conditions dictate.
To keep your brooder in good operating condition, we recommend that after each crop
you blow any dust and dirt from the brooder with compressed air. If at anytime you notice
a lazy yellow flame as shown below then the brooder needs to be cleaned:
CAUTION:
TURN THE GAS AND ELECTRIC (IF EQUIPPED) SUPPLIES OFF
AND ALLOW THE BROODER TO COOL DOWN BEFORE
ATTEMPTING ANY MAINTENANCE.
Inspect the flame characteristics by running the brooder with the Mechanical Ventilation
OFF and Natural Ventilation by opening the doors at the end of the house. This will result
in a flame that is more stable to observe.
If at anytime 25% or more of the flame turns yellow or on an annual basis, we
recommend that the burner and orifices be disassembled and cleaned. Built up deposits
in the burner will not be effectively cleaned with compressed air.
1. Release the main burner orifice fitting and pan from the burner by turning the swivel clamp.
CAUTION: In order to prevent damage to the control arm tubing, first place your hand under
the pan and allow the control to lower gently under its own weight.
NATURAL GAS MODELS ONLY. Remove the Combustion Air Ring.
2. Unscrew the main burner orifice from the orifice fitting and clean the orifice hole with a drill
bit the same size as the orifice or by soaking the orifice in acetone liquid cleaner. Dry the
orifice by blowing compressed air through it. NOTE: Care must be taken not to ream the
orifice hole to a larger diameter as this will result in over firing the burner and potentially
causing damage to the emitter.
