MTM 8-30, Original Manual

Page: 3 / 12

1. Intended application
The universal oil heater type MTM 8-30 is designed to heat up industrial
rooms not covered with central heating systems (workshops, car repair shops,
industrial shops, warehouses, storage buildings, basements, garages, etc.). The furnace can operate using most
oils, e.g. engine, transmission, hydraulic, diesel oil, HBO I, II and III type oil, with viscosity
not exceeding SAE 80.
DO NOT USE TRANSFORMER OIL
AS IT MIGHT CONTAIN SUBSTANCES HARMFUL FOR STOVE OPERATION

5. Safety aspects
The MTM 8-30 universal oil heater is powered by the alternating current network of 230V/50Hz. It is
equipped with three sensors, ensuring safe and economic operation of the device.
1. The bimetallic sensor, placed in the furnace chamber, reacts with short circuit of the contacts in the
thermostat when the temperature exceeds 40°C and with contact opening when the temperature drops below
35°C.
2. The bimetallic sensor is located near the downcast ventilator, with threshold temperature
of 100°C, opens the contacts when the said temperature is exceeded and causes switching of the stove in to the
