Gas Fires: Replacing a Broken Radiant
A-fire with a broken radiant is not only inefficient and fuel-wasting, but can also be dangerous. New radiants are easy to obtain; always insist on the radiants made for the particular type of fire. Turn off the gas at the meter cock and disconnect the supply at the union with a small spanner. Lift the fire away from the hearth and remove any dirt or dust which may have come down the chimney. Make no attempt to remove built-in fires, and take care that none of the cement luting is disturbed — this controls the draught to the fire.
Remove all the radiants, taking care not to break them. Clean the burner holes and dust them with a pipe-cleaner; cover the burner holes with rag or paper and brush out any dust and dirt which collects under the canopy, in the flue nozzle and round the burners. A vacuum cleaner is excellent for, this. Examine the clay discs or gauzes on each burner and replace any that are broken. A broken disc can cause a gas-fire to pop when lit, or when turned out. Crush the broken radiants and mix them with water. Paint the firebrick at the back of the fire and the radiants with the wash, the new ones as well as the old unbroken ones.
Replace and refit the fire, then carefully replace each radiant. Test the fire by turning on the gas and lighting the fire, examine each radiant to ensure that all are equally incandescent, and adjust the tap so that flames do not project above the top of the radiants.
