c) Set the black spring depressor
according to the gas used. The
black spring depressor has two
(2) teeth at each end that fit in
to the brass nut but only one end
has a larger disc. If the disc sits
inside the cap then the valve is
set for natural gas and if the disc
is pointing out then the valve is
set for propane (see Figure 28).
d) Reinstall the spring depressor and brass nut onto the unit.
e) Install the unit back into the fireplace. Check the venting and the unit itself are correctly
installed.
8. Reinstall the burner (reversing the procedure in step 4), log set & embers (refer to S
ECONDARY
I NSTALLATION - I NSTALLING L OG S ET AND E MBERS ), and glass door. Note: When installing the burner, the
venturi shutter rod should slip into the venturi shutter adjustment hole.
Warning: Never run the unit without the glass door installed.
9. Open the shut-off valve at the gas line to the unit.
10. Use a small brush to apply a warm soapy water solution to all gas connections (use half dish soap
and half warm water). If a gas leak is present, bubbling will occur. Gas leaks can be repaired by
using an approved pipe thread sealant or approved Teflon tape. NEVER USE AN OPEN FLAME WHEN
TESTING FOR LEAKS. Check the gas pressure of the appliance, refer to I NITIAL I NSTALLATION - G AS

and Table 6.
11. Reconnect the electrical power to the unit.
12. Light the pilot and check for proper flames (see Figure 9). Light the burner in both the “HI” and “LO”
positions to verify proper burner ignition and operation and proper flame appearance. The amount
of air to the venturi may need to be adjusted using the rod under the firebox. Pull the rod forward
for more air or push it in for less air (see Figure 8). Also refer to Figure 79 for a flame appearance
picture.
13. MAKE SURE that the conversion label is installed on or close to the rating label to signify that the unit
has been converted to a different fuel type.
Figure 28: Set Gas Type for Valve. Figure 27: Remove Brass Cap.

a) If unit is installed, pull the Sonnet out from the fireplace.
Ensure you do not damage any of the venting or the unit itself.
b) Using a 7 /
8
” wrench, remove the brass nut at the back left of
the unit (shown in Figure 27). A small black spring depressor is
clipped into the back of the brass nut.
