RIGHT HANDLE ASSEMBLY:
Place the #3 steel collar over the #2 steel shank and place the steel
shank through the ½” hole located on the bottom of the right door. Then place the #4 spring over the ½”
shaft sliding it against the cast iron door. Then while supporting the steel shank underneath with a hammer
or such, install the #5 expand pin. Note that the #5 expand pin must be installed with the pin facing so that
when the door is closed the spring handle will be facing to the right. SEE THE ASSEMBLY IN FIGURE
1 & 3. To adjust the right door, simply pull on the steel shank to give it a little spring tension and then
tighten the set screw on the steel collar using the #9 Allen wrench provided. Adjust the door so that the
handle pulls the door up so that the gasket seals against the doorframe.
DO NOT OVER TIGHTEN THE
DOOR AS IT WILL TWIST THE CAST FRAME AND COULD CAUSE GLASS BREAKAGE
.
LEFT HANDLE ASSEMBLY:
Place the #3 steel collar over the #6 steel shank and place in the ½” hole
located on the bottom of the right door. Next, place the #7 set screw in the threaded hole directly below
the handle and turn into place. Align the #6 steel shank so that it is at the same angle as the left handle,
facing left. Then tighten the setscrew with the #9 Allen wrenches provided. Finally, slide the #3 steel
collar up against the cast and tighten. (SEE FIGURE 2)
NOTE:
The spring handles are installed by twisting them onto the ½” steel shank like you would screw on
a nut. Apply a slight amount of pressure as you turn the spring handles into place.
GLASS & GASKET REPLACEMENT
To remove the glass, take the door off of the frame by opening the door and lifting the cast iron door up
off of the hinges. Make sure that the door is cool before taking off of the unit. Move the door back and
forth as you lift. The hinge pins are snug. Lay the door on a newspaper or cloth to keep the soot and dirt
from getting on the floor. Next, using a Phillips #2 screwdriver, loosen the four-(4) screws that hold the
clips in place. (SEE FIGURE 4) Make sure not to bind the screwdriver against the glass. Remove the
glass that is broken and clean the area that the glass sits in. The replacement glass will have new gasketing
installed from the factory. Make sure that all of the old gasketing is removed from the door.
Carefully place the new glass in the door channel and replace the clips that hold the glass in place. When
installing the screws make sure that the clips are tightened evenly. Do not tighten the screws on one end
and then the other. The clips should put even pressure against the glass so it will not move but is not
binding. When you tighten the screws, remember that they are easily stripped and should only be tightened
enough to hold the clips firmly. Make sure that you do not bind the screwdriver against the glass. Finally,
be careful not to drop the cast frame as you align it with the hinges and slip it into place.
GLASS CARE - REPLACEMENT
The glass used for the
MAGNUM ZC
doors is a high temperature ceramic glass. If the glass breaks, it
must be replaced with factory replacement ceramic glass (SEE FIGURE 5 FOR DIMENSIONS).
Tempered or ordinary glass will not withstand the high temperatures of the
MAGNUM ZC
. Replacement
glass should be purchased from your dealer or the factory. Do not operate the unit with cracked or broken
glass.
