11、e is not available,gaskets shall beheated by other means to remove deformations and provide ahigh degree of flexibility and resiliency.This may be done bywarming them in hot water or heated containers.Gaskets shallnot be heated by being draped over heated units or placed indirect contact with a flam
12、e or fired heating device.Theinstallation of glass,panel,and lock-strip shall be completedwhile the gasket is still warm and pliable and with the gasketchannels clean and dry.4.4 Use of ToolsTo minimize the possibility of damage,sharp or pointed tools or implements such as screwdrivers orputty knive
13、s shall not be used on lock-strip gaskets.Suitablegasket installation tools,such as nonmetallic spatulas andengineered lock-strip insertion devices,are available from thegasket manufacturer.4.5 Use of LubricantsIf necessary a lubricant may beapplied to the contact surfaces of the gasket to ease thei
