Service Instructions for Your Heating System
Resetting a Burner Fault
Any faults in your heating system are indicated on the
display by a flashing fault symbol "
Read off the fault code in the display and report it to your
heating contractor. This helps the contractor to properly
prepare, and may result in lower service costs.
WARNING
Visually inspect the vent termination for any signs of
blockage. Under cold climate conditions [sustained
temperatures below 0° F (-18° C)] the vent termination
may be severely blocked by icicle and frost build-up.
The boiler control will automatically shut down the
boiler should air intake or vent be blocked. Remove
blockage if possible. Reset the boiler switch (ON / OFF
switch to OFF and then back to ON) (see page 10) and
the boiler should attempt to restart. If blockage is not
obvious and cannot be removed, contact a licensed
professional heating contractor.
Note: If
flashes and "R" appears on the display, the
burner is locked out.
Press and hold "R" for approx. 2 seconds. If the fault no
longer exists, the default display will appear.
Notify your heating contractor if the fault recurs.
WARNING
If faults are not rectified, they can have life
threatening consequences.
Do not reset the burner fault several times in quick
succession. Notify your heating contractor if a fault
recurs. Your heating contractor will be able to analyze
the cause and rectify the fault.
