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.
A few points must be considered before inserting the
738K into an existing fi replace cavity. Generally, no
modifi 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 baffl es may be removed to accommodate
the installation of the 738K engine. Cutting away
any sheet metal parts of the existing fi replace
to accommodate the installation of the 738K 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 738K 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 738K 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.
Installation Planning
Existing Fireplace Preparation
9. Install liner panels and fuel bed.
10. Refi t window.
11. Synchronize remote control system.
12. Verify operation and adjust aeration settings.
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, the front and the barrier
screen.
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 738K 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.
