Correct gas pressure requirement:
Supply Pressure
Natural Gas
Min. Pressure
5.0" WC
(For purpose of input adjustment)
Max. Pressure
13.9" WC
Manifold Pressure
Maximum
3.5" WC
Minimum 1.6" WC
Note: To test the gas pressure, turn off the gas supply before removing the blanking plug from
the supply pressure test port or manifold pressure test port.
Verify gas pressures with the fireplace lit and on the highest setting.
1. Remove the blanking plug from the pressure test port. The plug is located between the right side
lintel and firebox side (Figure 20).
2. Thread the extension test fitting into the open test port (Figure 21)
3. Attach a pressure gauge onto the fitting.
4. When testing is complete remove the extension test fitting and replace the plug. Thread sealant
will be required to ensure a gas tight connection.
