INSTALLATION

UNIT ASSEMBLY

PRIOR TO

INSTALLATION

The Top Facing Support, the Side Nailing Strips
and the 2 Top Standoffs must be correctly
positioned and attached to the top before unit
is slipped into position.

INSTALLATION

TOP STANDOFF ASSEMBLY

The top standoffs are shipped in a fl at position
and must be folded into shape and attached.

1) Remove the standoffs from the fi replace

top.

2) Take each standoff and bend into the correct

shape. Bend up at the bend lines until the
screw holes in the standoff and the pre­punched screw holes on the fi replace top
line up.

3) Attach the standoff securely to the top

with 2 screws per standoff (on opposite
corners).

SIDE NAILING STRIPS

The side nailing strips come attached to the unit.
There are 3 plates, one on the top and bottom
that can be folded out as required.

Side Nailing Strips shown folded out.

FINISHING TEMPLATE

In order to maintain a clean face; the L900
allows for a 1/8” in overlap of fi nishing material,
such as rock or tile, on both the left and right
hand sides of the unit (top and bottom sides do
not allow for an overlap), this overlap must not
be exceeded or the glass door will no longer
open properly.

Non-combustible wall board is installed up
to the fl anges on all sides of the unit. When
installing any additional facing material use
the Finishing Template (included with the unit)
to ensure that the fi nishing material does not
exceed the allowable overlap.

The Finishing Template uses two magnets to
attach itself to the fl ange on the left or right side
of the unit (see diagram below). Install the facing
material up to the outside edge (when facing
the unit) of the fi nishing template. This template
may be discarded after the facing material has
been installed.

Regency® L900 Direct Vent Gas Fireplace

INSTALLATION

VENTING

INTRODUCTION

The L900 uses the "balanced fl ue" technology
Co Axial system. The inner liner vents products
of combustion to the outside while the outer
liner draws outside combustion air into the
combustion chamber thereby eliminating the
need to use heated room air for combustion and
losing warm room air up the chimney.

Note: These flue pipes must not be

connected to any other appliance.

The gas appliance and vent system must be
vented directly to the outside of the building,
and never be attached to a chimney serving a
separate solid fuel or gas burning appliance.
Each direct vent gas appliance must use it's own
separate vent system. Common vent systems
are prohibited.

VENT RESTRICTOR

POSITION

Vent restriction is required for certain venting
installations, see the diagrams in the "Venting
Arrangements" section to determine if they are
required for your installation.

To set the vent restriction as indicated in the
venting arrangements diagrams, refer to the
instructions below;

1) Remove the glass door.

a. Release the 2 door latches on the left

and right side at the top of the fi rebox.

Regency® Direct Vent System

These venting systems, in combination with the L900, have been tested and listed as a direct vent system by Warnock Hersey. The location of the
termination cap must conform to the requirements in the Vent Terminal Locations diagram from the "Exterior Vent Termination Locations" section.

FPI Direct Vent (Flex) System Termination Kits include all the
parts needed to install the L900 using a fl exible vent.

2) Only Flex pipe purchased from FPI may be used for Flex
installations.

3) Horizontal vent must be supported every 3 feet.

4) A wall thimble is mandatory for all horizontal terminations

RIGID PIPE VENTING SYSTEMS

BASIC HORIZONTAL & VERTICAL TERMINATIONS

Rigid Pipe Vent Systems offer a complete
line of component parts for installation of both
horizontal and vertical installations. Many items
are offered in decorative black, as well as gal­vanized fi nish.

INSTALLATION

The minimum components required for a basic
horizontal termination are:

1 AstroCap XL
1 90o Elbow
1 Rigid Pipe Adaptor
1 Wall Thimble
1 Length of pipe to suit wall thickness

The minimum components required for a basic
vertical termination are:

1 Vertical Termination Cap
1 Rigid Pipe Adaptor
1 Lengths of pipe to adequately
penetrate roof
1 Ceiling Firestop
1 Flashing
1 Storm Collar

Wall thickness is measured from the back
standoffs to the inside mounting surface of
termination cap. For siding other than vinyl
furring strips may be used, instead of the vinyl
siding standoff, to create a level surface to
mount the vent terminal. The Terminal must
not be recessed into siding. Measure the wall
thickness including furring strips.
