disconnected and open the shut-off valve at the gas line
to the unit.

. If the unit 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.

10. Reconnect the electrical power to the unit.
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 hook (see Figure 25) . Should
the pilot require adjustment, turn the adjustment screw clockwise to decrease or counterclockwise
to increase until the correct flame is achieved.
