a) Type No. 1-K Kerosene is intended for use in unvented space heaters as described in CSA B140.9.3, when used in well-ventilated surroundings, and in wick-fed illuminating lamps.

b) Type No. 2-K Kerosene is intended for use in flue-connected stoves and heaters and should not be used in unvented applications.
