MANUAL RESET OVERHEAT
THERMOSTAT
Sealed system installations require the use of an overheat
thermostat which has to be reset by hand. Your boiler is fitted with
this thermostat as standard and may be reset by pressing the button
shown in Fig. 1. Access is gained by removing the case front panel.
If either thermostat persistently cuts out then your boiler
requires attention and you should call either your installer or a
service engineer.
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 two
signal lamps coming on: one is located in the boiler facia and the
other on the burner control box.
To cancel the burner lockout condition, remove the boiler
front cover (see installation and servicing instructions) and allow
two minutes before pressing the illuminated lockout reset button,
which is mounted on the burner control box. 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. Some appliances can be converted to
burn 35-second gas oil. If this conversion has been made your
installer will inform you.
PLEASE NOTE: Danesmoor room-sealed and conventional
low-level discharge appliances MUST NOT be used with 35-
second gas oil.
