1. Remove the plug from the pressure test port.
The plug is located between the right side
lintel and firebox side (Figure 44 and Figure
45).
2. Thread the extension test fitting into the
open test port (Figure 46).
3. Attach a pressure gauge onto the fitting.
4. Check all gas connections and ensure there
are no leaks.
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.
Correct gas pressure requirement:
Supply Pressure

Note: To test the gas pressure, turn off the gas supply before
removing the plug from the supply pressure test port or mani-
fold pressure test port.
There are four ports on this fireplace the top two are connected
to the rear burner and the bottom two are to the front burner.
Manifold pressures should be checked on both to ensure they
are correct.
Verify gas pressures with the fireplace lit and on the highest
setting.
