5. Replace the Burner Assembly: Slide the venturi
tube into the Air Shutter and engage the tube
fully over the orifice. The burner should engage
with the support brackets on the floor of the
firebox. Properly located, the burner will be level
and locked into correct alignment with the pilot
assembly as in fig. 13.
6. Adjust the Air Shutter:
• Slide the shutter forward (toward yourself) to
open the inlet. Slide it back to the rear to close.
The shutter is set at the half way position at
the factory. This is an optimum setting for most
installations using natural gas. Propane use,
however, may require a different setting.. See the
section, Flame Appearance / Air Shutter Adjust-
ment on page 22 for further details.
7. Change the Regulator: See Fig. 17.
• Using a Torx T-20 screwdriver or small spade
screwdriver, remove the three specialty screws
from the front of the valve regulator.
• Remove the regulator tower and gasket.
BE SURE TO REMOVE THE BLACK RUBBER GASKET
FROM THE VALVE.
• Install the new variable regulator tower with
the new rubber gasket. Thoroughly tighten new
regulator to valve body.
8. Apply the Conversion Labels:
• Apply LABEL A to the cabinet floor so that it
may be seen by anyone servicing the fireplace.
• Apply LABEL B to the Rating Plate in the space
provided.
9. Reassemble the fireplace, apply gas to the system
and check for gas leaks including all gas lines
before and after the valve. NEVER USE AN OPEN
FLAME TO CHECK FOR GAS LEAKS.
Use an electronic gas detector or 50/50 soapy
water solution to check for leaks at all connection
joints. The soap solution will actively bubble if a
leak is present. Tighten connections until no leaks
are detected.
IMPORTANT: Correct gas pressure is essential for
efficient and safe operation. It is important that
the correct gas pressure be established at the
time of the installation. For more details, see the
Gas Pressure section of this manual on page 15
and the Rating Plate.
