Step-by-Step Chase Construction
The following checklist is a simplified overview of typical chase construction for a built-in fireplace installation. This list is not
exhaustive and does not supplement thorough review of the installation manual.
Step 1
BUILD BACK AND SIDE WALLS
Frame the back and side walls according to framing requirements.
Build the platform (if necessary) to the desired height and install inside fireplace chase.
Platform must be stable and able to bear the full weight of the fireplace. Platform can be constructed out of wood, concrete,
metal, or any other solid materials. Material is not required to be non-combustible.
Step 2
INSTALL FIREPLACE AND VENTING, RUN GAS AND ELECTRICAL
Install the fireplace and venting. This must be completed by an authorized Ortal dealer (unless otherwise authorized by Ortal
with written approval).
Move the gas valve and receiver unit to the designated access panel location. If the fireplace will not have an access panel,
keep gas valve and receiver unit directly underneath the fireplace.
Run gas and electric to the gas valve and receiver unit location.
Step 3
BUILD FRONT WALL
Install front chase wall:
Build front wall according to framing requirements.
Stand up the front wall and move into place.
Secure front wall to the rest of the chase structure.
Cover the exterior of each wall (sides and front, and back if applicable depending on your design) with

Check to make sure constructed chase meets heat release and air intake (if applicable) requirements.
Step 4
APPLY FINISHES
Apply finishes and install accessories, following all clearances and building requirements.
Ensure furniture and other combustible materials maintain a minimum 36 inches of clearance directly in front of the fireplace
viewing area for both front and side viewing areas (as applicable).
