PureFire Installation
The PureFire™ can easily be installed in a factory built fireplace in less than an hour. Four mounting
screws will hold the two brackets in place. Then the PureFire™ is simply positioned on the mounting
brackets. It’s that simple. Just follow the directions as specified below:
1.
The PureFire™ Hood is has a trapezoidal shape to fit the angular sides of the firebox. The hood is
equipped with adjustable extensions that slide-in-and-out. The retro-fit devices can be adjusted for
firebox back wall widths.
2.
The PureFire™ should be installed after the fireplace is completely built. It is designed to be
installed as an add-on device. It is mounted on two brackets that are mechanically attached to the side
walls of the firebox. Insure that the firebox is structurally sound before beginning the PureFire™
installation. The brackets will be mounted on the sides of the firebox using the (4) factory built screws
(provided). It is very important to install the brackets in the proper location in the firebox as described in
STEP # 3.
3.
The two stainless steel brackets should be attached to the firebrick on the side walls with the
ends touching the back wall as shown in the diagram on the left. The height of the bracket installation is
determined by the fireplace opening. The brackets should be installed so that they are even with the
height of the fireplace opening (lintel). The brackets can be used to identify location of the mounting
screw holes. A black felt tip can be used to mark the location for drilling. There will be two holes drilled
on each side of the firebox. The firebrick is easily drilled with a 3/16” factory built carbide drill bit. Drill
the holes to a depth of 1”. A suitable hand tool should be used to attach the brackets to the sides of
firebox. Insure that the brackets are installed as shown on right. There is a lip on the bracket that
supports the PureFire™ Hood. The open end of the bracket should be facing the back of the firebox
while the closed end faces the front. The closed end of the bracket will prevent the PureFire™ from
moving after installation.
4.
After the brackets are installed, the PureFire™ hood should be adjusted to the right dimension
to properly fit into the brackets. Measure the distance between the installed brackets at their widest
point (front). Now, move the adjustable extensions on the hood until the widest dimension on the hood
extensions equals the widest dimension of the mounting brackets. The extensions should be extended
equally on each side. Now, tighten the retention screws on each side of the hood.
5.
The PureFire™ can now be installed in the firebox. Position the device in the brackets so that the
PureFire™ is securely in place. The closed end of the brackets will prevent the PureFire™ from moving
forward in the firebox. The PureFire™ should be located against the back wall of the firebox directly
above the grate. The damper handle (if required) should pass through the opening between the
combustor blocks and remain operational. Chain operated units will have the chain in front of the hood.
