Boiler installation

This chapter details how to install your boiler correctly.
This involves the following steps:
– Connecting the venting system
– Providing air supply for combustion
– Connecting the water pipes
– Making the electrical connections
– Connecting the fuel supply
Danger: Risk of fatal injury from toxic flue
gases.
V Never connect more than one boiler to a
flue system – regardless of whether the
flue is vertical or horizontal.
V Common venting appliances can cause
damage to property and personal injury.
V Do not route the flue system through an-
other flue system that is in use, e.g. a ma-
sonry chimney connected to a wood
stove.
V Follow the instructions of the flue pipe
manufacturer.
The boiler must be installed by a trained and
certified installer in accordance with all re-
quirements of NFPA-31, "Installation of Oil-
Burning Equipment". Installation must com-
ply with all local and national codes applica-
ble to the installation of oil-fired boilers.
In Canada, the requirements of CSA/CGA-
B139.1 and 2 Installation Codes apply.
The GB125 boiler is approved for zero (0")
clearance between its concentric vent pipe
and combustibles.
Because of the tight construction of modern
houses, this boiler must draw all air supply for
combustion from outside (RLU).
Logano GB125 BE US/CA - Technical specifications are subject to change without prior notice.
