Installation Planning
Installer—READ THIS FIRST
1. YOU NEED TO KNOW FROM THE
HOMEOWNER what accessories (surround,
door, etc.) will be installed with this
fi
replace;
2. Unpack the appliance.
3. Check that you have everything.
4. Clean cavity, chimney, ash dumps, clean-outs.
5. Install venting pipe.
6. Attach conversion plate to existing
fi
replace.
7. Fit appliance into cavity.
8. Connect and test gas supply.
9. Install the remote control system.
10. Install bricks and logs.
11. Re
fi
t window.
12. Verify operation and adjust aeration settings.
Existing Fireplace Preparation
A few points must be considered before inserting the
738BX into an existing
fi
replace cavity. Generally, no
modi
fi
cations are allowed to the existing
fi
replace that
will compromise the integrity of the existing
fi
replace.
Components that are bolted or screwed on such as
dampers or baf
fl
es may be removed to accommodate
the installation of the 738BX engine.
Cutting away
any sheet metal parts of the existing
fi
replace
to accommodate the installation of the 738BX is
prohibited
. Check with local authorities if in doubt.
Clean Fireplace and Chimney
Have the chimney swept and the
fi
replace cavity
including ash dumps and clean-outs cleaned before
installing the 738BX heater and vent liners. Any
creosote or soot residue remaining in the
fi
replace
cavity chimney or clean-out may cause odors or
stains once the 738BX insert is installed. Consult with
chimney sweep for information on how best to clean.
Existing Dampers
Factory-built, zero-clearance
fi
replaces will require the
damper to be removed in order to install the vent liners.
These dampers are usually bolted into place. Dampers
in masonry
fi
replaces must be
fi
xed open and may
remain in place.
13. Install the remote control handset wall holder.
14. Instruct the homeowner on the operation and
maintenance of the
fi
replace.
15. Install the surround trim and front.
16. Install the fret if required.

Ash Retaining Curbs
Some
fi
replaces (particularly factory-built) have a
raised curb at the front edge to retain ashes. Check the
dimensions carefully to ensure the 738BX engine will
fi
t
behind any raised curb (some curbs may be removed
separately from the refractory base).
Gas Line Routing
Plan the routing of the gas line before proceeding.
Use the existing hole for the gas line in factory-built
fi
replaces. If the
fi
replace has no access hole, carefully
drill an access hole of 1.5 inch (38 mm) or less through
the lower sides or bottom of the
fi
rebox. The access
hole must be plugged with non-combustible insulation
after the gas supply line has been installed. See
Dimensions
section for detailed location of gas inlet.
Also, take into consideration whether or not a shut-off
valve will interfere when planning routing of the gas
line.
