MASTER BV 471S Indirect Oil Heater

MASTER-BV-471S-Indirect-Oil-Heater-PRODUCT

DESCRIPTION

This series of heaters is particularly suited to heating medium to large-sized rooms or areas. Thanks to an internal heat exchanger, indirect heaters (PIC.

separate combustion gases from the hot air released into the environment. This way it is possible to have a flow of clean hot air in the area that needs to be heated up and direct combustion products outside. These heaters have been designed in line with the most recent safety, operating and duration criteria. The safety devices ensure the heater always operates correctly.

If the heater is placed on the platform, lower it gently using suitable devices and instruments, in accordance with national regulations and current standards. It can be lifted with the forklift truck, by using suitable chains and suspension hooks (the heater is equipped with eyebolts).
Check for any damage incurred during transport. If the heater appears damaged, immediately inform the dealer from whom it was purchased.

ASSEMBLY

(PIC. 2)
These heaters are equipped with handles, brackets, supports, etc. depending on the model. These parts, which come with the relative nuts and bolts, are in the heater’s packaging.

FUEL

WARNING: THE HEATER ONLY WORKS WITH DIESEL OR KEROSENE.
Only use diesel or kerosene to avoid any fire or explosion hazard. Never use petrol, naphtha, solvents for paints, alcohol or other highly inflammable fuels. Use non-toxic, anti-freeze additives in case of very low temperatures.
It is recommended to use winter diesel oil below 5°C.

OPERATING PRINCIPLES

The burner pump draws the fuel from the tank and sends it to the pressurised nozzle where it is nebulised and mixed with comburent air in the combustion chamber. A spark triggers combustion while the waste fumes are expelled from the chimney. A series of sensors constantly checks the correct operation of the heater, stopping the cycle in the case of a fault. The fan, located at the rear of the heater, cools the combustion chamber and the flue gas pass, transferring the heat from the latter into the environment.

IGNITING THE HEATER:
Follow all the safety instructions.
Connect the fuel pipes respecting the correct inlet and outlet connections (PIC. 4).
Check if there is any fuel in the tank.
Connect the supply plug to the power mains (PIC. 5) (SEE VOLTAGE IN THE “TECHNICAL DATA TABLE”).
Set the “ON/OFF” switch to “FLAME” (C PIC. 3). The heater should turn on within a few seconds. If the heater does not start, refer to paragraph “TROUBLESHOOTING”.
The heater can be used in ventilation mode, which is activated by setting the ON/OFF switch to “FAN” (C PIC. 3).
The heater has a ventilation control button (D PIC. 3).
- BUTTON ON: The ventilation works continuously (ideal for extreme conditions of use).
- BUTTON OFF: The ventilation works automatically (normal operation).
For models with a room thermostat, check the set temperature (PIC. 6).
NOTE: IF THE HEATER SWITCHES OFF DUE TO LACK OF FUEL, TOP UP THE TANK AND RESET THE HEATER (SEE PAR. “RESET THE HEATER”). IMPORTANT: IN INDIRECT MODELS, COMBUSTION PRODUCTS CAN BE DIRECTED OUTSIDE VIA THE DUCTS. CARRY OUT THE DUCTING IN ACCORDANCE WITH CURRENT REGULATIONS AND FOLLOW THE INSTRUCTIONS IN THE RELEVANT SECTION OF THE MANUAL.
TURNING OFF THE HEATER:
Turn the “ON/OFF” switch to “0” (C PIC. 3). The flame turns off and the fan keeps on working until the combustion chamber has fully cooled down. Do not pull out the electrical plug until the cooling cycle has ended.

RESET THE HEATER

In the event of an anomaly during the normal operation, the heater switches off.
To restart the heater, identify and eliminate the cause that caused the stop (for instance, obstruction of the air intake and/or outlet, fan stop, lack of fuel, etc.). If it is not
possible to eliminate the problem that caused the stoppage, contact a support centre for technical assistance.
In order to reset the heater, we recommend following the procedure below (follow all safety-related instructions):
