REFRACTORY BRICK INSTALLATION
The refractory bricks for the ONYX2 fireplace are placed in the fireplace at the factory. If, for any reason, they
should need to be replaced the following order should be observed (see Figure 17). To remove any of the
refractory bricks, just follow the installation procedure in the reverse sequence. Refer to Figure 17 to adequately
identify which refractory brick is the right and which is the left at each step of the installation.
1. First, remove the front secondary air tube
at the top front of the firebox to be able to
install the two half baffles. To do so,
unscrew the bracket located on the left
side of the front tube.
2. Then place the two half baffles (11.6.N)
above the other two tubes and ensure
their proper orientation: the two half
baffles are slightly rectangular, the longer
side goes from front to back of the
fireplace. They also have a mating groove
to fit well together in the middle of the
firebox.
3. Reinstall the first tube and screw it in
place.
4. Continue by installing both side refractory
bricks (left 11.2.N and right 11.1.N).
5. Then install both back refractory bricks
(both 11.3.N).
6. Next install the bottom refractory brick
(11.7.N).
7. Continue by installing both front refractory
bricks (left 11.5.N and right 11.4.N).
8. Finish by installing the bottom round
refractory brick (11.9.N).
These refractory have been designed specifically for the ONYX2 and no modifications are required to ensure a
proper fit.
GAS LOG INSTALLATION
The ONYX2 can be converted into a gas fireplace as long as you keep the combustion air control lever all the way
open (towards the right) and make the modifications to the fireplace as explained below. This is to allow enough
air for an adequate and safe operation of the gas log. You can use any gas log set up to a maximum of 35,000
BTUs that is listed to ANSI Z21.60/CSA 2.26.
WARNING: THIS FIREPLACE HAS NOT BEEN TESTED WITH AN UNVENTED GAS LOG SET. TO
REDUCE RISK OF FIRE OR INJURY, DO NOT INSTALL AN UNVENTED GAS LOG SET INTO THIS
FIREPLACE.
Remember that the installation of the gas line should be done by qualified personnel. All gas installations should
be in accordance with local ordinances and the appropriate Gas Code.
We do not require any minimum clearances between the side or the top of the firebox and the gas log set.
However, any clearances stated by the gas log set manufacturer must be maintained. You may install the gas
valve inside the firebox if the gas log set manufacturer allows this in its installation instructions, and if the required
clearances are met.
To convert the ONYX2 please carefully follow the following steps:
1. There is a 1 ¼" hole on both sides of the fireplace, about 9" up from the bottom of the fireplace. The gas line
must come into the fireplace through one of these holes. Choose the side of installation that is more
convenient to you.
