Install nozzle/check electrodes
1. Loosen the clamp screw on the retention ring assembly (see Figure 9,
step 1). Slide the retention ring assembly off of the nozzle adapter.
2. Install and tighten the nozzle listed in the appliance instruction manual or
Carlin OEM Spec Guide.
3. If nozzle information is not available, begin with the nozzle listed in Table 1,
page 3. (You may have to change the nozzle later if combustion results are
not acceptable.)
3. Hold the nozzle adapter securely as shown in Figure 9, steps 2 and 4, when
removing or replacing the nozzle. Take care not to damage the electrode
insulators or to bend the electrodes in the process.
Inspect the nozzle adapter before replacing the nozzle. If the
threads have been damaged or show score marks, replace
the nozzle line/adapter assembly.
4. Install the retention ring assembly by slipping one of the riveted arms
through the gap between the electrode tips. Align this arm straight up, with
the ring clamp fi rmly against the nozzle adapter shoulder (see Figure 10).
Then tighten the clamping screw.
5. Check the electrodes and reposition if necessary. Position the electrodes
as shown in Figure 10. These settings are critical in ensuring a reliable
ignition. Once the electrodes are set, check all clamps to be sure they are
securely tightened.
6. Insert the combustion head/nozzle assembly into the burner.
