MANUAL RESET OVERHEAT
THERMOSTAT
Sealed system installations require the use of an overheat ther-
mostat which has to be reset by hand. Your boiler is fitted with
this thermostat as standard and may be reset by pressing the but-
ton situated underneath the boiler shown in Fig.1.
DUCT MANUAL RESET THERMOSTAT
The boiler is fitted with a duct manual reset thermostat to
prevent the appliance operating if there is a fault in a seal or insu-
lation. The thermostat may be reset by pressing the button shown
in Fig.1.
If any of the thermostats persistantly cuts out then your boiler
requires attention and you should call either your installer or a
service engineer.
FROST THERMOSTAT
A frost thermostat is fitted as standard to protect the boiler in
frost conditions. If there is a possibility the central heating /hot
water system may be exposed to frost conditions, an additional
frost thermostat should be fitted. The boiler should remain con-
nected to the mains power supply to enable the boiler to operate
in the event of a frost condition.
A flame failure device is incorporated into the control system
of your boiler. So, should the flame fail for any reason, or should
ignition fail to initiate a satisfactory start, the boiler is automatically
locked out for safety. This lockout condition is indicated by a sig-
nal lamp lighting up on the boiler facia.
To cancel the burner lockout condition press the lockout reset
button, situated underneath the boiler shown in Fig.1. Provided
the system is still calling for heat, the burner will then operate and
commence another start cycle.
Persistent lockout indicates a fault and an engineer should be
called, so do not attempt to repeatedly restart the boiler.
Your Worcester Danesmoor pressure-jet boiler is set to burn
28-second kerosene fuel.
PLEASE NOTE: The Wall Mounted Danesmoor appliance
must not be used with 35-second gas oil.
