6. Convert the burner orifice(s):
a) Remove the main burner orifice with a ½

b) Put a bead of pipe-thread sealant or
approved Teflon tape on the orifice
threads before installing into the brass
elbow.
c) Install the new orifice(s) from the kit into
the brass elbow.
7. Convert the SIT gas valve:
a) Remove the black protection cap from
the HI/LO knob by hand shown in Figure
11.
b) Insert a
5
/
32
” or 4 mm Allen wrench into
the hexagonal key-way of the screw (see
Figure 12), rotate it counter-clockwise
until it is free and extract it.
c) Check that the screw is clean and if
necessary remove dirt.
d) Flip the screw (refer to Figure 13).
e) Using the Allen wrench as shown in
Figure 12, rotate the screw clockwise
until a torque of 9 inch lbs. WARNING!
Do not over tighten the screw. It is
recommended that you grip the wrench
by the short side.
f) Verify that if the conversion is from NG
to LPG, the screw must be re-assembled
with the red o-ring visible (refer to Figure
14). If the conversion is from LPG to NG,
the red o-ring of the screw must be not
visible.

. When re-installing the burner, ensure that the
burner to pilot hood relationship is similar to what is shown in Figure 15. On some units you will
need to pay special attention when installing the burner that the venturi adjustment rod is properly
installed into the venturi adjustment piece welded to the burner venturi tube
9. Reconnect the main gas line if it was disconnected and 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 a 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.
11. Reconnect the electrical power to the unit.
