Vent Maintenance; Fireplace Chase (Cavity) Construction - ORTAL Lyric Front Facing Series Installation And Operation Manual

Vent Maintenance

Regular inspection of the venting system by a qualified service technician is recommended every six
months. The following maintenance routing is recommended:
1. Inspect for excessive condensation, e.g., water droplets forming in the inner lining, and
subsequently dripping from the joints. This can cause corrosion in the system.
2. Check for corrosion in areas exposed to the elements. Components with rust spots or holes must
be immediately replaced.
3. Ensure that there is no foreign material in the vents. Survey by removing the cap and shining a
light down the vent.
4. If possible, check all joints and pipes to make sure that nothing has been disturbed or loosened.
The process of building the chase can be divided into four main phases:
PHASE 1: BUILD BACK AND SIDE WALLS
•
Frame the back and side walls.
o If using wood framing or plan on putting a TV or artwork above the fireplace, cover the inside
of the walls (the side facing towards the cavity) with 5/8" Type X Drywall or equivalent and
level 1 finish.
o If using metal framing and there is no TV or artwork, inside layer of 5/8" Type X Drywall or
equivalent is not required.
•
Build the platform (if necessary) to the desired height and install inside fireplace cavity. See section
titled, "Floor/Platform" for details.
PHASE 2: INSTALL FIREPLACE & VENTING, RUN GAS & ELECTRICAL
•
Install the fireplace. This can only be completed by an authorized Lyric dealer (unless otherwise
authorized by the manufacturer with written approval). See the section titled, "Fireplace Installation
Instructions" for details.
•
Install pipe/venting. See the "Fireplace Installation Instructions" section for details.
•
Move the gas valve & receiver unit to the designated access panel location. If the fireplace will not
have an access panel, keep gas valve & receiver unit directly underneath the fireplace so the
components can be accessed through the burner.
•
Run gas and electric to the gas valve & receiver unit location
•
Always be aware of local codes and regulations when working with gas and electrical equipment.
PHASE 3: BUILD FRONT WALL
•
Build front wall (aka infill panel):
o Build the front wall using metal or wood studs.
▪
o Stand up the front wall and move into place.
o Secure front wall to the rest of the cavity structure.
•
Cover the exterior of each wall (sides and front, and back if applicable depending on your
design) with 5/8" Type X Drywall (or equivalent) and level 1 finish.
PHASE 4: APPLY FINISHES
•
Apply finishes and install accessories. Make sure to follow all clearances as outlined in the section
titled, "Clearance & Finish Diagrams".
•
Turn the project over to the customer. See "Turning Project Over to End User" section for details.
