HeatPack Furnace Installation and Operation Manual

8. Install the new gasket on the glass. Remove a part of the

paper covering the gasket adhesive. Center the gasket on the

edge of the glass so that when folded and glued, the gasket is

equal on both sides. Do not stretch the gasket during

installation. Remove a majority of the paper, turn the glass to

facilitate and complete the installation of the gasket. When

you return to the starting point, cut the gasket so that the ends

overlap by about 1/2" (13 mm).

9. Install the glass (E) and glass frame (D) centering them in the door frame. Install the

glass retainers (C) taking care not to over tighten the screws (B). Note that the two

main causes of glass breakage are unequal position in the door and screws too tight.

10. Install the new door gasket (A). To do this, use about 1/4" (6 mm) of adhesive to the

bottom of the groove that holds the gasket in the door. Then lay the new gasket starting

from the center of the hinge side and taking care not to stretch the gasket during

installation. Leave about 1/2" (13 mm) of gasket exceed the frame of the door. Once

jointed, push the fibers protruding towards the inside of the groove in the adhesive.

Install the door and let dry for 24 hours before using the furnace.

Do not abuse the glass door by striking or slamming shut. Do not use the furnace if the

glass is broken. To change the glass, perform the same operation described above.

11.1.5 Cleaning and painting the furnace

Do not attempt to clean or paint the furnace when the unit is hot. Painted surfaces

can be wiped down with a damp cloth. Plated or enameled surfaces may be scratched by

abrasive cleaners. To maintain the finish at its original brilliance, use only a damp soft

cloth to clean plated or enameled surfaces.

If the paint becomes scratched or damaged, you can give your wood furnace a brand new

look by repainting it with heat-resistant or enamel finish paint. Before painting, roughen the

surface with fine sand paper, wipe it down to remove dust, and apply two thin coats of

paint.
