B. Gauge Installation
1. Connect the pressure test kit between the heater and
its gas supply hose as shown in Fig. 22. Ensure both
gas shut-off valves on the test kit are in the closed
position when connecting the kit to the heater and
gas supply.
2. Open the fuel supply valve to the heater.
3. Open only the gas shut-off on the test kit to which the
gas supply hose is connected.
4. Adjust the thermostatic head to its maximum setting
and light the heater.

C. Reading Pressures
1. With all of the heaters within the zone operating at
full heat output and at minimum heat, the pressure
gauge should read the pressure specified on the
dataplate of the zone panel.
2. Does the reading on the gauge of the test kit agree
with that specified on the dataplate? If so, then no
further checking or adjustment is required. Proceed
to Section D.
3. If the pressure does not agree with that specified on
the dataplate, then the regulator controlling gas
pressure to the heater requires adjustment.
D. Completion
1. Once gas pressure has been confirmed and/or
properly set, close the fuel supply valve to the heater
and allow the heater to burn off any gas remaining in
the gas supply hose.
2. Remove the gauge kit and reconnect the heater’s gas
hose to the heater.
3. Open the main fuel supply valves to the heater. Light
the heater.
