If the valve continues to weep afterwards, contact your qualified

4. If water does not flow from the valve when you lift the lever
completely, the valve or discharge line may be blocked. Immedi-
ately shut down the boiler, following the operating instructions
on page 9. Call your qualified service technician to inspect the
boiler and system.
END OF SEASON MAINTENANCE
To continue operation for DHW
1. If the boiler is to supply heat for domestic hot water generation
during the summer, no changes should be needed. Just leave the
boiler power on and allow the DHW storage tank to call for heat
as necessary.
2. Set back room thermostats to prevent any unnecessary call for
heat during the off season.

To leave boiler in stand-by mode
1. The SlimFit boiler's Sola control provides effective features for
stand-by operation, including automatic operation to reduce

the boiler and system during the stand-by period.
The Sola control must be configured to operate all
pumps needed to ensure the system and all circuits will
be protected against freezing. See the SlimFit Boiler
manual for details.
3. Set back room thermostats to prevent any unnecessary call for
heat during the off season.
