Step 9..Attach.the.conversion.label.provided.
in.the.conversion.kit.to.the.rating.plate.on.the.
appliance.
Step 10..Turn.on.gas.supply.and.test.for.gas.
leaks.
Step 11.. Attach. manometer. to. the. manifold.

pressure.reads.3.5.inches.water.column.(0.87.
kPa). for. natural. gas,. and. 10.0. inches. water.
column.(2.49.kPa).for.propane.gas.
ALWAYS TEST PRESSURES WITH THE VALVE

SETTING.
Step 7...(Refer.to.Figure 56 on Page 31 and
Figure 59)
VERIFY THE PROPER ORIFICE SIZE BE-
FORE INSTALLING IT.
A..Remove..the.orifice.from.the.manifold.and.
replace.it.with.the.one.provided.in.the.kit..See.
the.following.table.for.orifice.sizes.for.natural.
and.propane.models . Figure 59 illustrates.
the. orifice.. . Use. pipe. joint. compound. or.
Teflon.tape.on.all.pipe.fittings.before.installing.
(ensure.propane.resistant.compounds.are.
used.in.propane.applications,.do.not.use.pipe.
joint.compounds.on.flare.fittings)..
B..Retrieve.the.burner.and.slide.the.venturi.tube.
over.the.orifice...Set.the.burner.assembly.
into.its.position.and.secure.it.
C..Reinstall.the.grate.assembly..
Step 6...Refer.to.Figure 58 .and.remove.the.
pilot.hood.assembly.to.access.the.hexed.pilot.
orifice...Remove.and.replace.the.orifice.with.
