Follow these start-up instruction steps for 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 individually controlled
heaters, directly on the heater, to its maximum
temperature setting. See Fig. 7.

3. Fully depress the button on the safety control valve
while applying flame to the inner cone point. Keep
the button fully depressed for about 30 seconds until
the inner cone stays lit. Allow outer combustion cone
to heat up completely.
4. Adjust the temperature by decreasing the setpoint on
the thermostatic head to the desired temperature.
The heater will cycle from low heat to high heat
based upon thermostatic head set point.
