This Korean Industrial Standard specifies open type (4)of movable gas heater (3) (hereafter referred to as 'heater') which the indicated amount of gas consumption (2) is not less than 7 kW : 25.2 MJ/h{0.5 kg/h, 6000 kcal/h}, which is using fuel vessel filled up with liquefied butane gas (1) (hereafter referred to as 'gas').
Notes (1) The liquefied butane gas refers to the gas specified in class 2, number 4 of KS M 2150.
(2) The amount of gas consumption refers to the amount consumed when the movable gas heater is used in the state of the most gas consumption, and it is indicated on the product.
(3) The movable gas heater refers to that it is to move with the gas vessel built-in within the heater body without lifting, and it makes the room warm with radiation heat emitted by the combustion gas.
(4) The open type refers to that the air for combustion is gained indoors, and combustion gas is exhausted indoors from the heater as it is.
Remarks 1. The units and numerical values in { } of this standard are in accordance with conventional system of units, and are appended for informative reference.
2. The indicated gas consumption of this standard is written in 4 kinds of unit and numerical values, but each kind is the same value substantially.
3. The pressure mentioned in this standard is gauge pressure except the pressure indicated with atmospheric pressure.
