4) The burner continues to repeat the starting cycle without going into lockout.
This is a very specific situation caused when gas pressure in the gas main lines is very close to the value at which
the gas pressure switch has been set. This can be corrected by resetting the gas pressure switch to a lower level.
The gas pressure switch, if required, may be supplied, or may have to be field installed.
5) The burner does not go through prepurge, and the control module goes to lockout. The air pressure switch does
not change over from normally closed to normally open contacts.
This condition exists because there is insufficient air pressure in the combustion head.
OWNER INFORMATION AND ROUTINE MAINTENANCE
SAFETY LOCKOUT
This burner is equipped with multiple interlocking safety devices. In the event of a failure in the flame, or any blockage
of the combustion air supply, the burner will "lock out" in a safety condition. In such an event, an illuminated red
button will show on the centre front of the red cover. To restart the burner, press the button once only. Should the
burner return to the lock out condition, call a qualified service technician or your gas company for assistance.
NOTE: Keep the area around the burner free and clear of all combustible materials, gasoline and other flammable
vapours and liquids. Do not allow any obstructions, which may prevent the free, flow of air to the burner.
MAINTENANCE
Like all precision equipment, your burner will require periodic maintenance. At an interval of 2 months, you should:
1) Visually check the flame if your heating appliance has an observation port.
2) Check and clean the air intake louver to remove any builds up of fluff, dust, pet hair etc.
3) The motor is permanently lubricated and does not need oiling.
For any maintenance or repairs over and above those listed, contact your service technician or gas company. THERE
ARE NO OWNER SERVICEABLE PARTS INSIDE THE BURNER COVER.
Once a year, you should have the burner serviced as indicated below. This service should be performed by your local
authorized Riello dealer.
1) Check burner distributor head and mixing plates. Clean if necessary.
2) Check ignition electrode. Clean, adjust, or replace as necessary.
3) Check the flame sensor rod (ionization rod) for dirt or carbon build up. Clean, adjust, or replace as necessary.
4) Check manifold gas pressure.
5) Check all burner adjustments.
6) Generally clean all exposed parts and components.
7) Do a complete combustion test with the burner cover in place and the air gate locking screws secure.
Your Riello 40 gas burner is only part of your heating system.
Once every year you should have your heating appliance serviced by a qual-
ified service technician.
You should also have the chimney checked, and cleaned if necessary.
