CLEARANCES

The clearances listed below are Minimum distances unless otherwise stated (refer to diagrams in the "Locating Your Fireplace" section):

Clearance to Combustibles from:
Back 0" (0mm)
Side 0" (0mm)
Floor 0" (0mm)

CAUTION REQUIREMENTS: The top, back and sides of the fi replace are defi ned by standoffs.
The metal ends of the standoffs may NOT be recessed into combustible construction.

Determine the total thickness of the fi nished fl oor (eg. tile, carpet, slate) to allow the fi nished
surface to be fl ush with the base of the unit.

Side 1-1/2" (38mm)
Bottom 1-1/2" (38mm)

Vertical Vent Clearances 1-1/4" (32mm)

COMBUSTIBLE MANTELS

Mantel Clearances

Because of the extreme heat this fi replace emits,
the mantel clearances are critical. Combustible

mantel clearances from top of unit are shown in
Diagram to the right.

Note: A non-combustible mantel may be

installed at a lower height if the framing
is made of metal studs covered with a
non-combustible board.

WARNING:

Fire hazard is an extreme risk

if these clearances (air space)

to combustible materials are

not adhered to. It is of greatest

importance that this fi replace

and vent system be installed

only in accordance with these

This drawing is to scale at 1:6 (one inch = 6
inches)
Mantel can be installed anywhere in shaded area
or higher using this scale.

Caution: Ensure the paint that is used on the

mantel and the facing
is "heat resistant" or the paint may
discolour.

* If the 3" (76mm) metal extension trim is removed
it must be replaced with a 8" (203mm) non­combustible material.

Regency® P121-2/P121LC-2/P121RC-2/P131-2 Zero Clearance Direct Vent Gas Fireplace

FRAMING AND FINISHING

INSTALLATION

1) For ease of installation, frame your fi replace after it is positioned and
the vent system is installed. Remember to install the top standoffs.
See the "Unit Assembly Prior to Installation" section. Use 2x4's and
frame to local building codes.

CAUTION: Verify your fi replace dimensions, framing methods and
fi nished wall facing details before framing. Determine the total
thickness of facing material - drywall plus ceramic tiles, slate, etc.
Allow the fi nish surface to be fl ush with the front or side of the
unit. Total facing thickness can vary from 1/2" (13mm) to 1-1/4"
(32mm) thick.

2) When locating your appliance on an exterior wall or in a chase, apply
a vapour barrier and drywall, as per local building codes. DO NOT

INSULATE THE FIREPLACE ITSELF.

CAUTION: The unit does not have to be completely enclosed in
a chase. The clearance on top of the unit is 0" to the standoffs
so combustible building materials can be laid directly on top
of the standoffs. You must maintain clearance from the vent to
combustible materials for both rigid and fl ex, see Vent Clearances
in the "Clearances" section.

Facing & Finishing Requirements

This fi replace is supplied with a 3" metal extension trim above the fi replace. The extension trim may be replaced if the framing is faced with a non­combustible material placed fl ush with the front and side face of the unit and extending from the top of the unit. (ie. tile, slate, etc.)

UNIT ASSEMBLY

PRIOR TO

INSTALLATION

The 4 Top Standoffs must be correctly positioned and attached to the top before unit is slipped
into position.

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 4
screws per standoff (on opposite corners).

VENTING

INTRODUCTION

The P121-2/P121LC-2/P121RC-2/P131-2 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. (See "Rigid Pipe Venting
Systems" for more details and exceptions).
