1. If installed, remove all media and the
burner tray.
2. Remove the plug from the pressure
test port using a 3/16” hex key. The
pressure test ports are located next
to the center tray leg opposite from
the pilot (Figure 93).
3. Thread the extension test fitting into
the open port (Figure 94).
4. Attach a pressure gauge onto the fit-
ting and rest the gauge on secondary
floor where it will be visible with the
doors closed and unit running.
5. When testing is complete shut off
the gas, remove the fitting and
replace the plug. Thread sealant will
be required to ensure a gas tight
connection.
Note: To test the gas pressure, turn off the gas supply before removing the plug from the supply pres-
sure test port or manifold pressure test port.
Verify gas pressures with the fireplace lit and on the highest setting.
