in your Owner’s Manual. When re-installing the burner, ensure that the burner to pilot hood and
shield relationship is similar to what is shown in Figure 24.
9.
Reconnect
the main gas line if it was disconnected and open the shut-off valve at the gas line to the
unit.
10.
Reconnect the electrical power to the unit.
7. Convert the SIT gas valve:
a)
Use a T-20 driver to remove the two screws that hold the servo regulator to the gas valve and
disconnect the wire harness from the IFC.
b) Remove the rubber regulator diaphragm that is situated between the servo regulator and the valve
body. The new servo regulator already has this diaphragm installed.
13.
Relight the main burner in both the “MAX” and low positions to verify proper burner ignition, operation
and proper flame appearance (figure 51, page 36). Confirm the inlet and manifold pressures are
within the acceptable ranges as directed in section

If the EX32 has been installed at an altitude higher than 2000ft (610m) it is required to
de-rate the unit accordingly:
In the USA:
The appliance may be installed at higher altitudes. Please refer to your American Gas
Association guidelines which state: the sea level rated input of Gas Designed Appliances installed at
elevations above 2000 (610 m) feet is to be reduced 4% for each 1000 feet (305 m) above sea level.
Refer also to local authorities or codes which have jurisdiction in your area regarding the de-rate
guidelines.
In Canada
: When the appliance is installed at elevations above 4500 feet (1372 m), the certified high
altitude rating shall be reduced at the rate of 4% for each additional 1000 feet (305 m).
14. 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.
11.
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.
12.
Relight the pilot and confirm the flame properly
covers the flame sensor (see Figure 24)
.
Should
the pilot require adjustment, turn the adjustment
screw (figure 34, page 29) clockwise to decrease
or counterclockwise to increase until the correct
flame is achieved.
