Technical information3
3.2.3 Combustion air supply conditions
3.2.4 Fuel conditions
3.2.5 Power supply conditions
Small animals – Protect the boiler room and particularly the combustion air inlet against the entry
of small animals, for example by means of a screen.
Fire protection – Maintain clearances between the boiler and flammable materials in accordance
with local regulations. A minimum clearance of 16" is required. Never store
flammable materials or liquids in the vicinity of the boiler.
Flooding – In case of an acute risk of flooding, disconnect the boiler in good time from its fuel
and power supply before water enters the room. Any general and burner
components or control equipment, which come into contact with water, must be
replaced before re-commissioning.

Operating conditions
Boiler output (in case of several
boilers = total output)
Ventilation air cross-section in square inches
(unrestricted aperture)
Ventilation cross-section for
combustion air from outside
(split over a maximum of
2 apertures)
< 170,000 Btu/hr min. 23,25 square inches
> 170,000 Btu/hr min. 23,25 square inches and also 0.91 square inches
per 10,000 Btu/hr,
that is above 170,000 Btu/hr
Tab. 5 Combustion air supply – observe local requirement for operation with room air.
Operating conditions Notes – Requirement in greater detail
Permissible fuels for boilers
without integral burners
– This boiler can be operated with the following fuels. Select a burner that is suitable
for one of these fuel types:
– Fuel oil in accordance with the burner specification
If a poorer quality oil (kinematic viscosity > 0.0093 sq in/sec (> 45.5 s
Sayboldt) at 68 °F) is used, the maintenance and cleaning periods must be
reduced. In that case, carry out maintenance and cleaning procedures at least
twice a year.
– Natural gas in accordance with the burner specification
– LPG in accordance with the burner specification
Contamination – Technically free of contaminants (for example dust, mist, humidity), i.e. a
constant operation will not lead to accumulation, which causes reductions in the
cross-section of valves, strainers and filters.

Operating conditions Notes – Requirement in greater detail
Power supply voltage 110 – 120 V Note the voltage range of the burner and control devices used. The housing/boiler
must be grounded for reasons of function and personnel protection.
Fuse (Logamatic) 10 A
Frequency 60 Hz Sinusoidal voltage curve
Protection – IP40 (protected against contact by entry of foreign bodies > 0.04 inches Ø
(> 1 mm Ø), no water proofing)
