Guardian Agricultural Animal Confinement Building Heaters

Start-Up Instructions

Follow steps 1 - 6 on initial start-up after brood heater
installation by a qualified gas brood heater service
person. For normal start-up, simply turn thermostat
above room temperature. The brood heater will start.
1. Open all manual fuel supply valves and check
for gas leaks using approved leak detectors.
The gas control valve on the brood heater has
a manual shut-off feature incorporated into the
valve assembly and may be located under a metal
cover. Remove the metal cover and make sure the
indicator on the valve is turned to the "on" position.
Replace the metal cover. See Fig. 6.

2. Connect the electrical cord to an approved electri-
cal outlet.
3. Set the thermostat to desired room temperature.
4. This brood heater includes a hot surface ignition
(HSI) control module for purposes of controlling the
timing of the ignition process of the brood heater as
well as monitoring of the safety functions. The HSI
module is contained within the control enclosure.
On the HSI module is a red light emitting diode
(LED). This LED indicates the status of the heater.
The LED is visible external of the control enclosure
through the plastic eye. A constant light from the
LED is an indicator that the heater is functioning
correctly. Any flash pattern by the LED is indicative
that there is a problem in the operation of the
brood heater. Refer to the troubleshooting decal
on the access panel at the fan motor end of the
brood heater for assistance in troubleshooting.
Only qualified and properly trained personnel shall
service or repair the brood heater.
5. On a call for heat, the motor will start up and run
for five (5) seconds and then stop. This pre-purge

is a safety feature and a normal operational character-
istic prior to ignition taking place. After the motor has
stopped, the igniter will heat up (approximately 15 sec-
onds). After igniter warm up time has been achieved,
the motor will start again and shortly thereafter ignition
will occur.
NOTE: It is normal for air to be trapped in the gas hose
on new installations. The brood heater may
attempt more than one trial for ignition before
the air is finally purged from the line and ignition
takes place.
6. The HSI control will make up to three trials for ignition.
Each trial for ignition will take approximately 20 sec-
onds. The first two trials for ignition will occur within 40
seconds if ignition is not achieved. A 15 minute wait
period will then begin after the second trial for ignition
has taken place. After the 15 minute time span has
elapsed, the third and final trial for ignition will take
place. If ignition is not achieved at this final trial, the
system will lock out, and a three flash pattern will be
indicated by the LED.

Shut-Down Instructions

If the brood heater is to be shut down for cleaning, main-
tenance or repair, follow steps 1 - 5. Otherwise, simply
turn thermostat to off or no heat for standard shut down.
1. Close all manual fuel supply valves.
2. With the brood heater lit, allow heater to burn off
excess fuel in gas supply hose.
3. Turn the indicator on the gas control to off.
4. Turn thermostat to off or no heat position.
5. Disconnect the brood heater from the electrical supply.
