D.H.W. PRODUCTION
The.preparation.of.hot.water.is.guaranteed.
by.the.glass.storage.tank.unit.with.magne-
sium.anode.for.the.protection.of.the.boiler.
unit. and. inspection. flange. for. its. control.
and.cleaning..
The magnesium anode must be checked
annually and substituted when it is worn,
pain the forfeiture of the guarantee of the
storage tank. If the boiler does not produ-
ce hot water, make sure that the air has
been released by pressing on the manual
vents after having switched off the main
switch.
4.2
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.
.
4.3
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.opera-
tion.
–. Configure. the. new. fuel. as. indicated. in.
point.4.3.1
–. For. calibrating. the. maximum. and. mini-
mum. gas. pressure. values,. see. point.
4.3.2.
.
–.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.
