Before operating this heater, please review the safety
precautions given on page 2 as well as the items list-
ed below:
1. The air shutter on the burner stem should be
secured to a minimum opening of 3/8" for Natural
Gas. Propane Gas should be fully open.
2. Check to make sure the logs and rock wool have
all been placed correctly. Refer to Steps 8 and 9.
3. Check to see that all wiring is correct and
enclosed to prevent possible shock.
4. Check to ensure there are no gas leaks. This
may be done with a soap and water solution.
5. Make sure the glass is sealed and in its proper
position. Never operate this heater with the door
opened or glass removed or not sealed.
6. Verify that all venting and caps are unobstructed.
Exhaust gases are extremely hot. Check for
obstructions from trees, bushes, snow drifts, etc.
7 . Read and understand these Instructions thorough-
ly before attempting to operate this heater.
WARNING!

Pre-Use Check List
STEP 9 - Placing the Rock Wool.
Tear the rock wool into pieces, no bigger than 1/2"
diameter, and place them over the front gas ports so
that the flame can touch the rock wool. This creates
the glowing ember look. Be sure not to pack the
rock wool against the gas ports. See Figure 23.
Step 10 - Clean the Glass.
To clean the glass, use a non-abrasive, mild cleaning
solution. (For example, a glass cleaner or for stubborn
film, an oven cleaner.) Apply an adequate amount to
the glass and wipe off with a damp cloth. Be sure all
cleaner is thoroughly rinsed from the glass.
Step 11 - Install the Glass.
After cleaning the glass, carefully place it into the frame
assembly. Slide the slots of the bottom of the frame
assembly over the screws on the front of the firebox.
Replace the [3] screws at the top of the frame assem-
bly. Snug the screws being sure not to over tighten
them.
Snug the screws at the bottom being sure not to over
tighten.
Step 12 - Replacing the Front Face.
Carefully lift the Front Face into position, reversing the
procedure A in this section.
WARNING!
DO NOT OPERATE APPLIANCE WITH THE PANEL(S)
REMOVED, CRACKED OR BROKEN. REPLACE-
MENT OF THE PANEL(S) SHOULD BE DONE BY A
LICENSED OR QUALIFIED SERVICE PERSON.
Step 10 - Adjustable Flue Restrictor
The R-Cast has an adjustable flue restrictor for maxi-
mum performance for vertical installations. The unit
is shipped with the restrictor in the open position and
should be left open with any horizontal installations.
By turning the bolt in the firebox to the right (tighten)
and sliding, the restrictor will close. See Figure 24.
The amount to close the restrictor will depend on the
flue height.
If the vertical height is 20 feet or more, the restrictor
can be closed all the way. Anything less will require
some setting less than closed. That setting will vary
depending on the installation.
Any offsets in a vertical installation will restrict the
system and the flue restrictor will not need to be
closed as much.
