If the control system does not influence the heating circuits or the a heating circuit actuating component (e. g. Pumplogic), the burner ON mode must reach an operating temperature of 122 °F within 10 min by restricting volume flow.
3
Boiler control thermostat setting: During burner ON mode the minimum boiler water temperature in the boiler must be reached within 10 minutes by suitable measures, such as flow restriction, and maintained as the minimum temperature.
Operating conditions Notes – Requirement in greater detail
Temperature in the boiler room +40 to +104 °F
relative humidity max. 90 % No condensation or precipitation inside the boiler room
Dust/airborne seeds Excessive dust inside the boiler room must be avoided when the boiler is
operating, e.g.:
dust from building work
Combustion air supplied from outside must not be excessively loaded with dust or airborne seed; if necessary, air filters should be fitted to prevent this:
Air supply contaminated with dust from dirt roads and paths.
Air supply contaminated with dust from production and processing facilities,
e.g. quarries, mines, etc.
– Airborne seed from thistles and similar
Halogen-hydrocarbon compounds
The combustion air must be free from halogen-hydrocarbon compounds.
– Identify the source of halogen-hydrocarbon compounds and prevent them
from entering. Where this is impossible, route combustion air from areas that are not contaminated by halogen-hydrocarbon compounds.
Fans, which extract air from the boiler room.
During burner operation, no mechanical air handling equipment may be operated
that could extract combustion air from the boiler room, e.g.:
Extraction hood
Clothes dryer
Ventilation equipment

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.
