This conversion kit shall be installed by a qualified
serviceagencyinaccordancewiththemanufacturer's
instructionsandallapplicablecodesandrequirements
oftheauthorityhavingjurisdiction. Iftheinformation
in these instructions is not followed exactly, a fire,

The installation is not proper and complete until the
operation of the converted appliance is checked as
specified in the manufacturers instructions supplied
with the kit.
IMPORTANT
The burner orifices provided in this kit are only for
use at elevations of 0 to 2,000 feet (610 M) in the
uSA and 0 to 4,500 feet (0-1372 M) in Canada. At
higher elevations the BTu input must be de-rated
by 4% for every 1,000 feet (305 M) to maintain
the proper ratio of gas to air. If the installer must
convert the unit to adjust for varying altitudes, a
derationinformationstickermustbefilledoutbythe
installer and adhered to the appliance at the time
of the conversion. Contact your local gas supplier
for deration requirements for your area.

Step 8.Tighten the pilot stem by turning it clockwise, making sure the
orifice slider stays pushed into the NG position.
STEP 9.
40,000 BTu
Using a 1/2” open-end wrench, remove burner orifice. Replace
with 1/8” NG orifice that is supplied in this kit. Make sure to use
pipe sealing compound on threads of new orifice (see Figure 7).
IMPORTANT NOTE: When this appliance is installed with the 1/8”
orifice (40,000 BTU’s), increased mantel clearances are required.
See Page 8 of the Installation and Operation Manual.
