Start-Up Instructions
Follow steps 1-4 on initial start-up before
building repopulation. For normal start-up,
simply turn the thermostatic head above room
temperature.
1. Open all gas supply valves to the heater(s)
and check for gas leaks at all connections
using approved lead detectors.
2. Adjust the thermostatic head, located on
either the zone control panel, or for individu-
ally controlled heaters, (located directly on the
heater), to its maximum temperature setting.
See Fig. 7, zone panel is shown.

3. Fully depress the button on the safety control
valve while applying
fl
ame to the inner cone
point. Remove the vinyl cap from the safety
valve if necessary. See Fig.8, I-17 shown.
Keep the button fully depressed for about 30
seconds until the inner cone stays lit. Release
the button. Allow outer combustion cone to
heat up completely. Replace the cap onto the
safety control valve.

4. Set thermostatic head to desired temperature. The
heater will cycle from low heat to high heat based
upon thermostatic head set point.
■
It is normal for air to be trapped in the gas line on
new installations.
■
It may take slightly longer for the heater to light
and stay lit after releasing the safety control valve’s
button until all air is purged from the gas line.
Shut-Down Instructions
To reduce temperature, simply turn down the thermo-
static control on the zone panel or on the individual
heater.
To shut down the heaters for maintenance, cleaning
or service:
1. Shut off all gas supply valves to the heaters.
2. Allow heaters to burn off fuel gas remaining in the
gas supply line.
3. Turn down the thermostatic head to minimum
setting.
