NOTE! IT IS STRONGLY RECOMMENDED THAT, ON LPG INSTALLATIONS, GAS DETECTION EQUIPMENT
IS FITTED. THIS EQUIPMENT SHOULD BE POSITIONED NEAR THE APPLIANCE AND AT LOW LEVEL. IT
IS ALSO IMPORTANT THAT THE SPACE HOUSING THE APPLIANCE IS ADEQUATELY VENTILATED AT
HIGH AND LOW LEVEL. THIS APPLIANCE MUST NOT BE LOCATED BELOW GROUND E.G. IN A CELLAR

RELATED DOCUMENTS
In addition to those documents listed in
Section 4.1: RELATED DOCUMENTS
within the main body of the
installer’s guide the gas installation should also comply with the guidance offered in the following documents.
BS 5482-1: 2005
Code of practice for domestic butane and propane gas burning installations.
Part 1:
Installations at permanent dwellings, residential park homes and commercial
premises, with installation pipework sizes not exceeding dn25 for steel and dn28 for
corrugated stainless steel or copper.
The operation of the CP-M+ range on LPG-Propane (3
rd
Family) 3P is similar to that on Natural Gas (2
nd
Family)
2H and the design and installation details described in the main body of the installer’s guide should be followed.

CONVERSION AND COMMISSIONING PROCEDURE
This process must be carried out in the order stated when the boiler is switched on for the first time. Failure to
follow the following procedure may lead to non-warrantable damage to the boiler.

TABLE 15.3
COMBUSTION GAS READINGS
Due to the design of the boiler, the conversion to LPG-Propane requires adjustment of the gas valve(s) only (see
Figure 15.1
). The sequence is as follows:
1.
Turn screw 2 (
Figure 15.1
) clockwise until fully closed. On models with two gas valves, this should be
done to both valves.
2.
Turn screw 2 counter clockwise in accordance with
Table 15.1.
On models with two gas valves, this
should be done to both valves.
