Fireplace Installation Instructions
Your Shasta Oil Hearth stove can be installed in front of a fireplace, thereby utilizing the
fireplace flue. The model Shasta may be vented out the rear and up the fireplace using a 4”
stainless steel liner to the chimney top. The model Shasta may be installed in front of all masonry
and all factory-built (zero-clearance) fireplaces.
Items needed for a fireplace installation:
1. Model Shasta hearth stove body (no legs).
2. #W-OSSK fireplace surround kit (includes 3 surround panels, 3 gold trim pieces).
3. 4” Stainless steel liner with adequate fittings for connection from the stove flue
outlet (4”) to chimney top. This liner assembly should include a flashing for
finishing off the chimney top, a rain cap, and a storm collar, as well as a connector
to the stove. A flex liner kit works well for fireplace applications, allowing unit to
be adjusted while out away from the fireplace face.
4. A 5/16” hex socket (driver) to attach panel to back.
You will need to plan for a means to get a 3/8” O.D. minimum copper fuel line into the
fireplace from tank source to connect to the carburetor. A flex section of fuel line or a coil of
copper tubing behind the unit will be helpful so that the connection can be made while the stove is
pulled away from the fireplace face and then pushed back into its final place.
Installation Procedure
Note: All clearances to combustibles listed in this manual must be maintained!
1. Fasten surround panels to unit. There are two side panels (12”x 23 1/2”) with
slotted holes, and one top panel (8”x 42”) with one slotted hole. Loosen the two
rear panel screws on the left stove back and attach the left panel using those same
screws. Leave screws slightly loose until the top panel is attached.
2. Repeat step 1 for right side panel, leaving screws slightly loose.
3. Loosen top screw at stove back and attach top panel, sliding down on screw slot
until the panel rests on the tops of the side panels.
4. Tighten top panel screw.
5. Slide left and right panels left or right until panel top corners are even with the
bottom corners of the top panel. Tighten side panel screws.
6. Assemble 3 piece gold trim at corners with a slotted screwdriver (left, right,
and top).
7. Slide the gold trim assembly down from the top, the surround panel edge sliding
into the 1/8” groove on gold trim back.
8. The unit is now ready to slide back to fireplace opening.
9. Connect flue liner pipe and fuel line to the unit, making sure there are no leaks.
As with a free-standing application, all other considerations of the installation
for proper operation must be observed, such as levelness of the unit, adequate air
supply, draft stabilizer adjustment, etc.
10. Light and operate the unit prior to sliding all the way back onto fireplace front so
that adjustment can be made to the draft stabilizer. This will not be possible after
the unit is back. Make sure there will be an adequate oxygen supply to the stove.
If the existing fireplace has an outside air supply, simply open and leave open.
11. Tune the stove following the carburetor adjustment instructions in this manual.
