Checkingthenonreturnvalveintheuppercasing,venturiandfan
1. Loosen with a 8mm wrench the top bolt of the fan ange
2. Unscrew the bottom bolt completely from the fan ange using a 8mm socket / crank
wrench
3. Remove the fan with gas valve from the upper casing and replace the black seal in
the upper casing by a new one.
4. Thefollowingoperationsmustbeperformedcarefullyinrelationtothevulne-
rabilityofthenonreturnvalve.
Remove the non return valve completely from the upper casing. Check the non return
valve if the entire circumference closes / seals completely. If the valve seals fully,
replace the non return valve back into the upper casing (transparent part inside).
Replace the non return valve if the valve does not seal properly.
- Check the venturi and gas distribution plate for pollution and clean them, if necessary,
with a soft brush and a vacuum cleaner. If the header is extremely dusty, then it is
likely that the fan is also dirty. To clean it, the ventilator has to be dismantled from the
upper casing and the venturi. Clean the fan with a soft brush and vacuum cleaner. At
the same time, replace the gasket and ensure that the new gasket is properly tted
when installing the ventilator parts.
Heatexchanger
- Check the heat exchanger for pollution. Clean it, if necessary, with a soft brush and
vacuum cleaner. Prevent any dirt from dropping down.
Rinsing the exchanger with water from the top is not allowed.
Assembly is done in reverse order.
