Any other use is considered inappropriate. Any damage that
results from such use is excluded from liability.
Installation, commissioning and servicing
Installation, commissioning and servicing must only be carried
out by a competent, Gas Safe registered engineer.
▶ Carry out a gas tightness test after completing work on gas-
carrying components.
▶ Only use original spares.
Electrical work
Electrical work must only be carried out by a qualified
electrician.
▶ Before starting electrical work:
– Isolate the mains electrical supply and secure against
unintentional re-connection.
– Check for zero potential.
▶ Also see connection diagrams of other system
components.
Warnings in this document are identified by
a warning triangle printed against a grey
background.
Keywords at the start of a warning indicate
the type and seriousness of the ensuing risk
if measures to prevent the risk are not taken.

2.1 Gas Conversion kits
To convert to LPG, a Gas Conversion kit is required.
The kit comprises:
• Gas pipe assembly
–Gas pipe
–O ring
– Dust shield
–Securing nut
• Heat Control Module (HCM)
• HCM tether
• Labels to confirm the new gas type
Table 1, page 5, lists the Gas Conversion kit part numbers.
2.2 Gas pipe conversion kit
Refer to the Installation, Commissioning and Servicing
instructions and remove the boiler front panel and combustion
chamber cover and put the control panel in the service
position.
2.2.1 Gas pipe
The gas pipe is supplied already assembled for ease of
installation.

NOTICE: COMBUSTION TESTING
▶ Combustion testing must be carried out by
a competent person. Testing must not be
attempted unless the person carrying out
the combustion check is equipped with a
calibrated Combustion Analyser and is
competent in its use
NOTICE: CO/CO

CHECKS
▶ If the joint between the Air/Gas manifold
and heat exchanger is disturbed the
sealing gasket must be replaced
▶ After completing the service of the
appliance, the CO/CO

instructions
CAUTION: Appliance siting
▶ This appliance must not be installed into a
room or internal space below ground level
when it is intended for use with LPG
(Propane - G31). This does not preclude
the installation into a room or space that is
in a basement on one side of the building
but is open to ground level on the opposite
side
CAUTION: Mains supplies
▶ Turn off the gas supply and isolate the
electrical mains supply before starting any
work on the appliance and observe all
relevant safety precautions

2.4 LPG conversion
Remove the four bolts securing the combustion chamber cover
and remove the cover to access the gas pipe.
2.4.1 Gas pipe removal
1. Remove the air intake pipes, if fitted, by pulling down and
away from the pre-mix chamber
2. Unscrew the gas pipe securing nut
3. Push the gas pipe assembly up into the pre-mix chamber, to
clear the gas valve
4. Move the assembly to the left into the space next to the gas
valve and pull the assembly down to remove
Fig. 4 Removing gas pipe
2.4.2 LPG pipe fitting
▶ Ensure that the O ring is fitted to the bottom end of the
pipe, refer to figure 1, a new O ring is provided in case the
original is lost or damaged
▶ Introduce the new gas pipe assembly into the space to the
left of the gas valve and insert the top of the pipe into the
pre-mix chamber
▶ Push the assembly up until it clears the top of the gas valve
▶ Pull the assembly down on top of the gas valve and secure
with the nut
▶ Re-fit the air intake pipes securely into the pre-mix
chamber
▶ Check the gas pressure at the gas valve, nominally 37mbar,
refer to the installation, Commissioning and Servicing
manual for the correct procedure. If the gas pressure is
satisfactory continue on to the CO

checks
▶Check the CO/CO
2
settings, refer to the table below, if the
CO/CO
2
settings require adjustment refer to the
Installation, Commissioning and Servicing manual for the
correct procedure.
▶ If all the checks are within tolerance, then fit the dust cap to
