4 USE AND MAINTENANCE
4.1 GAS VALVE (fig. 18)
The.boilers.are.equipped.standard.with.the.
SIT.845.SIMGA.gas.valve.(fig..18)..
The.gas.valve.is.set.at.two.pressure.values:.
maximum. and. minimum.. According. to. the.
type. of. gas. burnt,. these. correspond. to. the.
values.given.in.Table 4..
The. gas. pressures. at. the. maximum.
and. minimum. values,. are. factory. set..
Consequently.they.must.not.be.altered..
Only. when. you. switch. the. appliance. from.
one.type.of.gas.supply.(methane).to.another.
(butane.or.propane),.it.is.permitted.to.alter.
the.operating.pressure.
.
4.2 GAS CONVERSION (fig. 19)
This operation must be performed by
authorised personnel using original Sime
components.
To.convert.from.natural.gas.to.LPG.or.vice.
versa,.perform.the.following.operations.(fig..
19):
–. Close.the.gas.cock.
–. Disassemble.the.burner.manifold.(3).
–. Replace.the.main.nozzles.(6).supplied.in.a.
kit,.inserting.the.copper.washer.(4)..Use.a.
ø.7.spanner.to.perform.this.operation.
–. Configure. the. new. fuel. as. indicated. in.
point.4.2.1
–. For. calibrating. the. maximum. and. mini-
mum. gas. pressure. values,. see. point.
4.2.2.
.–.After.have.ultimated.the.conversion.of.the.
boiler,.please.stick.onto.the.casing.panel.
the. plate. showing. the. relevant. feeding.
gas.which.is.included.into.the.kit.
NOTE: When reassembling compo-
nents which you have removed, replace
gas seals; test all gas connections after
assembly using soapy water or a product
made specifically for the purpose, being
sure not to use open flame.
