Extinguishing; Boiler And Return Temperature; Daily Firing - Baxi MULTI-HEAT Instructions For Installation And Use Manual

If the boiler is fitted with oxygen control, set the control to OFF (button E), and a "sea of flames" can
be created by pressing fan symbols K and L simultaneously. The fan will run at a lower speed and the
augur will not start. When combustion is well underway, set the control to ON (button E).
1.5.2 Corn/grain:
Move the fuel towards the opening of the combustion chamber and switch the control to OFF.
Insert 5-6 handfuls of easily combustible material (e.g. wood chips or pellets) into the combustion
chamber at the fuel entrance. Then follow the instructions above.

1.6 Extinguishing

When extinguishing, set the control to OFF. Cinders and live coals must be removed from the combustion
chamber.

1.7 Boiler and return temperature

As already mentioned in section 1.3, we suggest that the boiler temperature should be kept at 80°C.
In order to minimise the risk of corrosion in the boiler, the return temperature ought to be min. 60°C.

1.8 Daily firing

1.8.1 Running in period
In the beginning, it is recommended that you should regularly (daily) inspect your boiler system
and check the fuel hopper, and fill this up, if necessary.
Check flow temperature, return temperature, as well as smoke temperature. See, amongst other
things, sections 1.3 to 1.7.
At the beginning, you ought regularly to open the lowest door and check the quantity of ash in
the bottom of the combustion chamber, in order to ascertain how often it is necessary to remove
the ash. (Let a little bit of the ash remain so that the air holes in the bottom of the combustion
chamber are just covered by ash).
1.8.1 Adjustment
The boiler ought to be adjusted first at high output (K) which only ought to be slightly higher than the
maximum heating requirement of the house. The recommended heat loss in an elderly house is approx.
80-160 W/m2 and in a more modern house, approx. 50 W/m
After this, set at low output - see technical data and use the recommended adjustment data from the PC-
diskette from BAXI A/S.
The colour of the flame ought to be yellow and slightly bluish.
