ensure no air leakage once the door has been installed. FIGURE 8 shows the insulation installed on
the back of the door frame. Refer to FIGURE 8 for anchor bolt installation.
The four bolts should be started in each of the welded nuts, 2 on each side of the door. Also
included with the door system are four anchor bolt caps. These caps are to be placed over the end
of each bolt. These caps reduce the “point stress” on the brick. This lower stress reduces the
potential of cracking or breaking the brick due to too much pressure being applied when the bolts
are tightened against the fireplace opening. The bolts should protrude as necessary through the
steel plate and welded nut but not so far as to interfere with setting the doorframe into the fireplace
opening.

STEP 3 – INSTALLING THE DOOR SYSTEM TO THE FIREPLACE
The fireplace door frame should now have the fiberglass insulation attached, the anchor
bolts should be threaded through the welded anchor nuts, the anchor bolt caps should be
attached to the end of the anchor bolts, and the brass trim should be squared and attached to
the side edges of the door frame. The fireplace door frame is now ready for final placement
and attachment to the fireplace.
Country Flame designs and manufacture’s fireplace door systems to maintain their appearance and
functionality over years of abuse from the repeated intense heat generated by large fires. As such,
these doors are built solid and they are heavy. The installer and homeowner should recognize that
the next installation step requires the lifting and attaching of a very heavy door frame. If properly
installed and attached to the fireplace, the fireplace door system will pay for itself over the years by
reducing the amount of wood fuel required or will increase the heat output for the same amount of
wood fuel burnt. This says nothing of the aesthetic value. Care should be taken to ensure that a
good seal is obtained between the face of the fireplace and the door frame. In addition, the installer
wants to ensure a solid door frame attachment to the fireplace.
At least two people should be used to set, level, and hold the fireplace door frame against the
fireplace opening while it is securely attached with the four anchor bolts. FIGURE 9 shows the
fireplace door set in place from inside the firebox. Ensure that the anchor bolts are tightened but
not excessively. If the anchor bolts are excessively over tightened against the fireplace’s brick
face, it could fracture the mortar or brick.
