The ash level in the ash pan should be checked periodically. The ash pan must never be
permittedtooverfill.Undernormaloperatingconditionsduringtheheatingseasontheashpan
will typically require emptying on a monthly basis. The appliance should never be operated
without the ash pan in position. The ash may be discarded with garden waste or in line with
local waste disposal regulations, after first ensuring that it is sufficiently cool before emptying
the pan. Caution: never attempt to remove the ash pan after the appliance has just

The combustion pot should be cleaned on a weekly basis removing any carbon residue.
Vacuuming with a dedicated ash vacuum cleaner is recommended. Failure to clean the

2.2 SystemPressure
When the appliance is connected to a sealed central heating
system,thesystempressureshouldbecheckedperiodicallyby
means of the pressure gauge at the expansion vessel (see
Figure 4). The WS18 appliance comes complete with an
integrated expansion vessel, pressure gauge and filling loop.
Theminimumpressure,asindicatedbytheblackneedle,must
notbelessthan0.5barwhentheapplianceiscoldandtypically
around 2.5 bar when the appliance is at normal operating
temperature. If the pressure is outside this range contact
Warmfloworyourinstaller.
2.3 SystemFilling

At filling or refilling of the system, special attention must be given to the concentration of
corrosioninhibitorsinthesystemwater.Where thereisaneedfortoppingup, concentrations
