Start-Up Instructions; Shut-Down Instructions - L.B. White TS080 Owner's Manual And Instructions

Follow steps 1 - 7 on initial start-up after heater installation
by a qualified gas heater service person. For normal start-
up, set thermostat above room temperature. The heater will
start.
1. Open all manual fuel supply valves and check for gas
leaks using approved leak detectors.
2. Connect the electrical cord to an approved electrical
outlet.
3. Set the thermostat to desired room temperature.
4. A selector switch is located on the back of the
heater. The selector switch allows you to either heat
or ventilate (no heat). The switch positions are as
shown in Fig. 8.
FIG. 8
When the selector switch is set to Heat, the heater
will cycle on and off based upon setting of the
thermostat. To use the heater for ventilating, position
the selector switch to Vent. With the switch in this
position,the fan motor will operate continually. The
thermostat will not cycle the heater, nor will the
burner ignite.
1. For normal shutdown (when fur ther use is
anticipated), position the selector switch to Off' and
the thermostat to off or no heat.
2. To properly shut down the heater for ser vice,
maintenance, or relocation:
a. Position the selector switch to Off and disconnect
the heater's electrical supply.
b. Close the gas supply valve(s) at gas source.

Start-Up Instructions

5. This heater includes a direct spark ignition (DSI)
control module for purposes of controlling the timing
of the ignition process of the heater as well as
monitoring of the safety functions. The DSI module is
located at the burner end of the heater. Refer to the
troubleshooting guide within this Owner's Manualif
equipment malfunction occurs. Only qualified and
properly trained personnel shall service or repair the
heater.
6. On a call for heat, the motor will start up and run for
five (5) seconds prior to ignition trial. This pre-purge
is a safety feature and a normal operational
characteristic. After five (5) seconds the igniter will
spark until burner flame is detected by the control
module.
NOTE: It is normal for air to be trapped in the gas
hose on new installations. You may have to
attempt more than one trial for ignition
before the air is finally purged from the line
and ignition takes place.
7. The ignition control will make three trials for ignition.If
ignition is not achieved, the controller will shut the
heater down. The ignition control must be reset.
Push and release the reset switch to restart the
heater. See Fig. 8.
8. Do not exceed the input rating stamped on the
dataplate of the heater. Do not exceed the burner
manifold pressure stated on the dataplate. Do not
use an orifice size different than specified for the
specific input rating of this heater, fuel type
configuration and altitude.

Shut-Down Instructions

c. Disconnect heater's gas pressure regulator from
gas source. A minimal amount of gas trapped in
the gas hose will escape. This is normal and will
not cause an unsafe condition.
