SECTION 13: CONVERSION BETWEEN GASES

SECTION 13: CONVERSION BETWEEN GASES
13.1 General
Conversion between gasses will require a change of
burner injectors and the gas valve re-commissioning
to the new conditions.
13.2 Burner Conversion
Conversion of the burner assembly from one gas to
the other is the same for all types of heaters.
1. Remove the burner compartment cover as
shown on Page 28, Section 15.2.
2. Remove the connection between the gas valve
outlet and the manifold. See Page 27, Section
15.1 for gas valve removal.
3. Remove the manifold from the burner assembly
by removing the screws at the top and bottom.
See Page 28, Section 15.2.1.
4. Remove the main burner injectors.
5. Replace with the injectors for the new gas
ensuring a gas tight seal.
6. Refit all components in reverse order.
13.3 Gas Valves
All gas valves used on the CTCU have pressure
regulators that may be set to operate on Natural gas
or LPG.
Conversion is carried out by re-setting the burner
pressure to the value in the data table during
commissioning. See Page 6, Section 4.3.
Ensure that the gas inlet pressure to the heater is
correct for the new gas, and that the gas supply has
been purged of the old gas.
ODELJAK 13: KONVERZIJA GASOVA
ODELJAK 13: KONVERZIJA GASOVA (prirodan
gas/LPG)
13.1 Uopšteno
Konverzija gasova zahteva promenu dizne u gorionik
i podešavanje gasnog ventila novim uslovima.
13.2 Konverzija gorionika
Konverzija je jednaka za sve tipove grejnih tela.
1. Uklonite poklopac gorionika kako je pokazano
nastrani 27, odeljak 15.2
2. Uklonite 4 zavrtnja koji drže razdelnik i izvucite ga
3. Ukloniteinshotgorionike rotirajući ih i pomerite
podupirač
4. Uklonite dizne glavnog gorionika
5. Zamenite sa ubrizgačima za novi gas
6. Podesite opet sve komponente
13.2 Gasni ventili
Svi gasni ventili koji se koriste kod CTU imaju
regulatore pritiska koji mogu biti podešeni za
funkcionisanje na prirodni gas ili LPG
Konverzija se vrši ponovnim podešavanjem pritiska
gorionika vrednostima u tabeli podataka tokom
podešavanja. Videti stranu 6, odeljak 4.3
Proverite da li je pritisak ulaznog gasa odgovarajući
za novi gas i da nema ostatatka starog gasa.
