Installing the boiler
This section details how to install your boiler correctly.
This involves the following steps:
• Flue pipe installation
• Providing air supply for combustion
• Making the water connections
• Making the electrical connections
• Connecting the fuel supply
5.1
Flue pipe installation
The overall burner air supply/boiler flue pipe system
conforms to the types of oil combustion equipment listed
in the table below.
Observe the national standards and regulations for
operating oil-fired appliances.
DANGER:
Risk of fatal injury from toxic flue
gases!
B
Never connect more than one boiler to a
flue system – regardless of whether the
flue is vertical or horizontal.
B
Common venting systems can cause
damage to property and personal injury.
B
Do not route the flue system through
another flue system that is in use, e.g. a
masonry chimney connected to a wood
stove.
B
Follow the instructions of the flue pipe
manufacturer.
The boiler must be installed by a trained and
certified installer in accordance with all
requirements of NFPA-31, "Installation of Oil-
Burning Equipment". Installation must
comply with all local and national codes
applicable to the installation of oil-fired
boilers.
In Canada, the requirements of CSA/CGA-
B139 Installation Code 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).
Installa-
tion type Combustion air supply and flue system
I
or
HT-K
Concentric supply air and flue pipe exiting
through external wall. Combustion air supply
and flue systems are part of the combustion
equipment.
II
or
DO
Concentric supply air and flue gas routing
via roof. Combustion air supply and flue sys-
tems are part of the combustion equipment.
III
or
GA-K
Concentric air/flue gas routing through a flue
inside a duct. The space around the vent
pipe is used for combustion air.
