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. Check that you have adequate space for servicing the equipment.
Riello Burner requires a minimum of 13 inches clear space behind the red cover.
This is required to allow easy removal of the cover for servicing and periodic maintenance.
4) Check that the chimney is of sufficient area to handle the exhaust gases.
Make sure that the chimney is clear and there are not obstructions.
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.
5) Affix the supplied operating instructions label to the burner. This label reads as follows:
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.
