Installing The Burner - Riello Two stage operation forced draught natural gas/propane burner Installation & Operating Manual

INSTALLING THE BURNER

A) Burner Chassis
B) Combustion Head Assembly
1) Locking Nut
2) Mounting Plate surface
3) Insulation Gasket
Separate the combustion head of the burner from the chas-
sis (A) by removing the locknut (1). Install the combustion
head into the boiler.
Typical insertion depth, the front edge of the combustion
head is flush with the inside surface of the appliance mount-
ing surface (2).
Use this checklist prior to installation:
1) Check the input/output requirements of the boiler/furnace.
2) Check the physical size of the combustion chamber against the thermal requirements of the application and relate
this to the sizing charts.
3) Check that there is sufficient air for proper combustion and adequate ventilation. Local codes should be followed.
4) Check that you have adequate space for servicing the equipment as per local code. This is required for servicing
and periodic maintenance of burner/appliance.
5) Prior to burner installation, the chimney must be inspected and must meet local code requirements.
6) Barometric draft regulators, when used, should be of the double acting type, and must be installed in accordance
with the draft regulator Manufacturer's instructions. Single acting barometric dampers are not permitted.
7) The operating instructions tag supplied with the unit must be left in place.
TO START THE BURNER:
Switch on power, open manual gas cocks, set the thermostat above ambient temperature. If the burner does not start,
press the illuminated re-set button on the burner safety control.
TO SHUT DOWN BURNER:
Switch off power supply. If burner is switched off for extended periods, close manual gas cocks.
IMPORTANT:
A vent shutoff system shall be applied to a barometric damper installed in the venting system at the
time of conversion of the appliance.
This will electrically disconnect the burner should there be a blockage in the vent (chimney).
The installer must identify the main electrical power switch and manual gas shut off valve, for emergency
conditions. The burner cover must be in place and secured before the burner is placed in operation.
