Gas Flow Adjustment
After completion of the fuel conversion, it is necessary to check the HI and LO pressures at the valve and may
be necessary to adjust one or both.
1. Install a gas gauge (Manometer) on the outlet pressure tap on the valve.
2. Light the fireplace using the remote handset.
3. With the fireplace on HI, set the maximum pressure to
10.0” w.c. (2.5kPa)
by adjusting the small flat
head screw in the center of the fuel conversion screw. Use only an appropriately sized jeweler’s
screwdriver. When complete, return the valve tray to original position and re-install screws.
4. Quickly press the small flame button on the remote to set the fireplace to LO.
Adjust the minimum rate to
6.00” w.c.(1.5kPa)
by turning the low pressure adjustment screw with a
4mm allen key as shown above.
5. When Hi and Lo pressure adjustments are complete, close the pressure tap(s) on the valve by turning
the screws clockwise. Check all connections/pressure taps for leaks.
