5.0 BURNER INSTALLATION AND SPECIFICATIONS
5.1 ASSEMBLY & INSTALLATION OF BURNER
CONSULT THE BURNER INSTRUCTION MANUAL THAT IS INCLUDED IN THE BURNER
BOX. In case of differences between the instructions on the burner instruction manual
and this manual, the furnace instruction manual (this manual) must be followed. The
instructions in the gas burner instruction manuals are detailed mounting, wiring,
adjusting, testing and maintenance instructions that are specific to the burner used
(Riello or Carlin). The specific adjustments for the furnace are detailed in the following
pages. As a general guideline:
1) Use the burner instruction manual for general instructions.
2) Use this manual for specific instructions (such as for example, the initial air gate
adjustment for a specific size of boiler with a specific burner).
•
RIELLO GAS BURNERS
o
In the Section “Setting the burner”, disregard the table and use the initial
adjustments detailed for the appropriate unit with Riello burner in the section 5.2
of this manual below.
o
In the section “Air gate adjustment”, disregard the table and use the information
in section 5.2 below.
o
In the section “Combustion head settings”, disregard the table and use the
information in section 5.2 below.
o
In the section “Manifold pressures”, disregard the table and use the information
in section 5.2 below.
o
Disregard the “Pressure working chart” and the “Combustion chamber size”
sections as those sections apply only for conversion burners.
COMBUSTION CHECKS
All combustion checks must be performed with an instrument capable of reading at least CO2,
CO and temperature.
•
RIELLO GAS BURNERS
o
Natural Gas Maximum CO2 is 10%
o
Propane Gas Maximum CO2 is 12%
o
Maximum Air free PPM reading of CO is 200.
o
If any of these readings exceed the values above, adjust the air gate to increase
the air intake to the burner.
AFTER PLACING THE BOILER IN OPERATION, THE IGNITION SYSTEM MUST BE
TESTED. THE METHOD OF TESTING IS AS FOLLOWS:
•
Place the furnace in operation, by raising the thermostat, and observe a normal
ignition of the burner.
•
Lower the thermostat. This should shut off the burner.
•
Close the manual shut-off gas valve that is upstream of the gas control.
•
Place the furnace in operation again, by raising the thermostat.
•
After a trial for ignition period, the burner control should go in lockout mode. A light
on the red button on the burner ignition control will indicate this.
