8 SERIES BOILER INSTALLATION AND OPERATING INSTRUCTIONS

BOILER LOCATION

Boiler should be located on a smooth level concrete
fl oor or pad close to the chimney to minimize breeching
length. Allow access for boiler cleaning and burner
maintenance.
Figure 1A
CAUTION - Boiler shall be installed on non-
combustible fl oor only, unless Figure 1A is
followed.

CHIMNEY AND BREECHING

Attach the smoke hood to the back of the boiler using
the 4 brass machine screws making sure to install the
gasket between the smoke hood and boiler. (Gasket
and hardware located in literature bag.) The 3 and 4
section models are equipped with a 6" smoke hood,
the 5 and 6 section models with a 7" smoke hood. The
boiler must be vented with vent pipe having the same
diameter as the smoke hood collar. Place the fl ue pipe
over the smoke hood collar and secure it to the collar
with a sheet metal screw.
The fl ue pipe should be run to the chimney by the most
direct route, with the minimum number of elbows and
with a slight upward pitch. The pipe should terminate
fl ush with the inside face of the chimney and should be
sealed in place with insulating cement. The boiler must
be vented to the outdoors by means of a tile lined ma-
sonry chimney.
For energy conservation, the boiler can be vented
directly into a chimney without the use of a barometric
draft control, unless required by code or in instances
where the chimney can develop excessive draft.
Overfi re draft greater than -0.05 inches W.C., with the
burner in operation, is excessive (normal draft is -0.02
to -0.04" W.C.).

COMBUSTION AND VENTILATION

Normal residential construction usually allows suffi cient
air infi ltration for combustion. If construction is tight,
consideration should be given for air louvers to the
outside. Local codes or NFPA 31, "Installation of Oil
Burning Equipment", should be referred to for proper
sizing and design and air supply. In Canada refer to CSA
STD. B149 - latest edition.
WARNING: This boiler must be connected to a
properly sized and constructed chimney or vent
system! Failure to comply with this warning
can result in a fi re which could cause extensive
property damage, severe personal injury or
death!
