Conversion to LPG
The Heater can be converted on site. NG to Pro-
pane, or Propane to Butane.
1.
With the Gas and Electrical supply off, undo
the three screws that hold the Venturi to the
Gas Valve. (
See Fig.6.0
)
2.
Allow the Gas valve to drop and gently hang
on its cables.
3.
Fit the Conversion Orifice into the Rubber
Seal that sits in the Gas Valve. (
See Fig.6.1
)
4.
Re-assemble the Gas Valve and Venturi.
5.
Affix the new LPG Serial Number Data
Label supplied over the existing.

LPG to NG Conversion
The method is as detailed above except the Orifice
is removed and the Venturi and Gas Valve reassem-
bled with just the Rubber Seal between them. A new
Serial Number Data Label should be obtained from
the manufacturer and affixed over the existing.
Gas Connection
The 22mm copper gas connection provided can be
positioned to exit the Heater from either the left or
the right. A minimum of 20mb. (NG), 37mb (propane)
28 mbar (butane) must be available at the Heater
inlet, with the Heater and other connected appli-
ances firing. Check for gas tightness (B.S. 6891:
1988) in pipework to boiler using a manometer.(
See
Fig. 6.2
) Gas and combustion soundness within the
Heater should be checked using sense of smell and
leak detection fluid. Check the maximum rate and
combustion are to specification.
See Table 6.0 and Datatable Inside Cover.
