9. Using a 3⁄8” socket wrench, remove both gas orifices from the orifice mounting brackets at the rear floor of the
firebox (Figure 55).
10. Use only the gas orifices that were included in the LP gas conversion kit supplied by the manufacturer. The
correct orifice sizes for the DV48 are shown in Table 6.

12. Remove the Valve Access Cover by removing

14. Remove the rubber regulator diaphragm that is situated between the servo
regulator and the valve body and replace with the one provide in the LP
conversion kit.
15. Install the LP servo regulator, with the new longer T-20 screws, included in the

16. If the fuel delivery pressure or the manifold pressure is to be verified, it can be
done at this stage.
a. Loosen the pressure tap screw.
b. Place a 1⁄4” silicone tube over either pressure port on the valve (refer to
Figure 59). Attach the tube to a monometer.
c. Install a burner in the firebox (see burner installation section)
d. Being careful to route the silicone tube away from the burner, test fire the
unit for only long enough to establish the pressure reading.
e. Check your inlet gas pressure by measuring the pressure at the inlet
pressure tap on the valve. Inlet pressure should be a minimum of 12” WC.
If the pressure reads less than this, have a licensed gas fitter determine
and rectify the reason for the reduced supply pressure.
