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 42). If the conversion is from LPG to NG, the red o-ring of the screw must be not visible.
g) Re-attach the black protection cap that was removed in step a (Figure 39).
9. Reinstall the burner, burner platform, log set, glass, and door frame. Also refer to the log Set inStallation
section on page 52.
10. Reconnect the main gas line if it was disconnected and open the shut-o valve at the gas line to the unit.
11. Reconnect the electrical power to the unit.
12. 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 Teon tape. NEVER USE AN OPEN FLAME WHEN TESTING
FOR LEAKS.
13. Relight the pilot and conrm the ame properly covers both the thermocouple and thermopile (see
Figure 5). Should the pilot require adjustment, turn the adjustment screw clockwise to decrease or
counterclockwise to increase until the correct ame is achieved.
14. Relight the main burner in both the “HI” and “LO” positions to verify proper burner ignition, operation and
proper ame appearance (page 38). Conrm the inlet and manifold pressures are within the acceptable
ranges as directed in the
gaS line connection section on page 41. If the S50 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 certied high
altitude rating shall be reduced at the rate of 4% for each additional 1000 feet (305 m).
15. 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 dierent fuel type.
