Caution Requirements
The top, back and sides of the replace are dened by
stando󰀨s. The metal ends of the stando󰀨 may NOT be
recessed into combustible construction.
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 replace and vent
system be installed only in accordance with these instructions.

FRAMING DIMENSIONS CB40E (3 SIDED)
NOTE: Framing may be constructed of combustible material (ie. 2x4) and does not require steel studs. Two (2) optional steel stud kits may also be purchased.
These kits may be used in place of the conventional wood framing as shown below. It comes as a compact kit (flush to the appliance on all sides)or
an extended kit. The extended kit protrudes beyond each side of the appliance as shown on the front cover of this manual. There is also an optional
hearth kit which may be purchased as shown on the front cover of this manual. These kits are highly recommended as it was designed specifically
for the product to facilitate ease of installation. See instructions in this manual for details.

Note: A combined minimum of 120 square inches of open area is required for the convection air outlet to cool the enclosure. Ensure clearances for
Convection Air Outlets are met. See clearances CB40E (3 sided) in this manual as there are di󰀨erent methods as to how this can be achieved.
Note: Only basic framing dimensions are shown. The framing may also extend beyond the appliance on either side and also extend out front if a hearth is
desired. See clearance/nishing requirements for details
Note: This appliance must be installed on
a solid surface such as a plywood oor
which must be the full width and depth of
the appliance.

MANTEL CLEARANCES CB40E (3 SIDED)
Due to the extreme heat this replace emits, the
mantel clearances are critical. Combustible mantel
clearances from top of front facing are shown in the
diagram on the right.
Note: Ensure the paint that is used on the mantel
and the facing is "high quality" or the paint
may discolour.

CB40E Gas Fireplace
VENTING INTRODUCTION
The CB40E uses the "balanced 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 ue 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.
VENTING ARRANGEMENT FOR HORIZONTAL TERMINATIONS
The diagram shows all allowable combinations of vertical runs with horizontal terminations, using one 90o(two 45o elbows equal one 90oelbow).
Note: Must use optional rigid pipe adapter (Part# 510-994) when using Rigid Pipe Venting Systems)
• Maintain clearances to combustibles as listed in "Clearances" section
• Horizontal vent must be supported every 3 feet.
• Firestops are required at each oor level and whenever passing through a wall.
• A vent guard should be used whenever the termination is lower than the specied minimum or as per local codes.
• Flex system can only be used up to 10 feet - otherwise rigid venting must be used.
VENT RESTRICTOR SETTING:
Vent restrictor factory set at Set 0.
Refer to the "Vent Restrictor Position" section for details on how to change the vent restrictor from the factory setting of Set 0 to Set 2 if required.
NOTE: A minimum of 1' (305mm) vertical o󰀨 the top of the unit is required before any horizontal runs can start.
Note: For horizontal terminations the Regency Direct Vent Flex System may be used for installations with a maximum continuous vent
length of up to 10 feet. If longer runs are required, rigid pipe must be used.

GUIDELINES FOR INSTALLING A TV/ARTWORK ABOVE THE UNIT
Note: All wiring should stay free and clear of the vent system to avoid damage
due to heat. We recommend using a metal receptacle box and BX cable (120
volt wire protected by metal sheathing) if located directly in front of the vent
system. Ensure wiring is secured without any sag.
ZERO CLEARANCE TO TV: While most consumers prefer to centrally locate
a wall mounted TV, the “Cool-Touch Wall Technology” means that the bottom
edge of the TV can be installed ush with the bottom edge of the ventilated
replace chase opening.
The TV may be recessed into a wall as shown below.
This can only recess into the chase opening a maximum of 3-1/2 inches
and must be a minimum of 12 inches from the replace lip to the rst stud.
To achieve a maximum of 3-1/2" recess, the wall must be of a maximum
of 2" as shown.
