INSTALLATION
B. FOR GAS INSTALLATION
1. The whole of the gas installation, including the meter,
should be inspected and tested for soundness and then
purged in accordance with the recommendations of the
relevant standards listed on page 4.

10. Operate the boiler for 20 minutes and for gas fired boilers
check the gas rate (Table 1).
11. Refer to the burner instructions for specific operating
features.

).
c. Refill and vent the system, clear all air locks and again
check for water soundness.
d. Balance the system.
3. Finally set the controls to the User's requirements.
Note.
We advise never to set the boiler thermostat below position 4
(approx. 40ºC) in order to avoid the risk of combustion products
condensing on the walls of the boiler.
IMPORTANT. Point out the owner that the boiler must have
regular maintenance and cleaning, at least annually, in order to
ensure reliable and efficient operation. Regular attention will
also prolong the life of the boiler and should preferably be
performed at the end of the heating season.
Recommend that a contract for this work should be made with
the regional gas authority or a CORGI registered heating
installer for gas fired boilers.
