7.4.3 Cold feed and expansion tank height for open vented systems
We recommend the boiler is installed on a closed (pressurised) system wherever pos-
sible with a minimum operating pressure of 0.8 bar. However, open vented systems
can be accomodated as follows: The cold feed and expansion tank heights for all open
vented systems must comply with the requirements laid down in the Health and Safety
Executive publication (latest execution).
The Remeha Quinta series boilers require a minimum static head of 3 m.
7.4.4 Safety valve
A safety valve should be fitted in accordance with the British Standards. Recommen-
ded minimum size of 15 mm (full bore type).
7.4.5 Gas connection
Connect the boiler to the incoming gas in accordance with the requirements of the Gas
supply company. Install the main gas cock near the boiler. The gas connection is loca-
ted at the bottom of the boiler. Fit a gas filter in the gas supply piping to avoid debris in
the gas control unit.
NOTE: The boiler is suitable for both natural gas and propane firing.
It is supplied as standard set for natural gas, therefore an adjustment to the gas valve
and the fan speed setting must be carried out BEFORE the boiler is fired and commis-
sioned for the first time on propane (ref. Par. 9.1).
