Air Inlet Liner (for combustion air) When

terminating the air inlet liner at this point, a

positive flue connection is required (to ensure

combustion air is drawn down the chimney

only).

Exhaust 3" (75mm) UL

1777. A full length liner

is required from the

exhaust outlet on appli-

ance to center collar of

termination cap.

Positive Flue Con-

nection (sealing

fireplace throat

using a noncombus-

tible seal-off plate

or insulation).

The outside air inlet does not

require a full reline (if intake

liner is terminated in chimney

and a positive flue connection

is achieved as specified).

Figure 6a - Terminating Air Inlet in Chimney

NOTE: Terminating the air intake liner as shown here may not be al-

lowed by some local codes. Check with the authority having jurisdiction

for your area.

Note: The minimum vertical rise (exhaust vent) is 10 feet (3.1 M) and the

maximum vertical rise is 35 feet (10.7 M). These dimensions are measured

from the starting collars of the unit to the end of the vent pipe.
The fireplace and fireplace chimney must be clean and in good working

order and constructed of non-combustible materials. Inspect chimney

cleanouts for proper fit and seal.
* Other approved vent components include; Standard Simpson Dura-

vent Co-linear Chimney Liner Kit, Direct-Vent Termination #991, Liner

Termination Kit (includes termination connector and flashing) #923GK

and 3" x 35' Alum Flex #2280

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Vertical Venting

The vent pipes must be connected to the proper collars on the unit and

the exhaust vent pipe must be connected to the termination cap or the

unit will not operate.
The combustion air intake pipe can be connected to the termination cap

(see Figure 6b) or it can terminate inside the chimney (see Figure 6a).

If combustion air intake pipe is terminated inside the chimney and not

connected to the actual termination cap the bottom opening of the chim-

ney (chimney throat) must be sealed around the vent pipes. Use a non

combustible seal-off plate (i.e. 22 gage sheet steel) or unfaced fiberglass

insulation (8 lb per square foot density minimum) to seal around the vent

pipes. Whichever “seal off” method is used must effectively seal the area

to prevent room air passage to the chimney of the fireplace. The insulation

may give off an odor during the first hour of operation.

Venting Installation

Your Superior™ gas insert must be vented to the outside in accordance

with the current edition of the National Fuel Gas Code ANSI-Z223.1 (In

Canada, the current CAN/CSA B149.1 installation code). The insert

must not be connected to a chimney flue serving a separate solid fuel

burning appliance.
This gas insert requires a 3” diameter listed flex liner. The vent should

terminate with a listed direct-vent termination cap. The chimney should be

sealed around the cap to prevent air and rain from entering the chimney.

Adhere to the vent manufacturer's instructions for installation and vent

termination. These appliances are approved for use with the following

vent kits.

The existing fireplace chimneys

may take various contours

which the flexible liners will

accommodate. However, keep

the flexible liner as STRAIGHT

as possible, avoid unnecessary

bending.

Liner Requirements:

Vertical Height Min. = 10 ft. (3.1 M)

Vertical height Max. = 35 ft. (10.7 M)

Note: Measured from flue collar on

unit to the end of the vent pipe or liner

Use 3" (76 mm) diameter listed gas

vent liner (UL1777 ONLY) for the

EXHAUST

Use 3" (76 mm) diameter listed

liner (UL 181 or UL1777) for the

AIR INTAKE.

The flexible vent pipe

must NOT be allowed to

sag behind insert or in

fireplace flue.

Make sure that both liners will pass through existing damper area. Remove

or lock damper to allow the passage of the flexible liners. If the damper

will not allow the passage of both liners, DO NOT PROCEED FURTHER.

(If fireplace is masonry) Consult a local mason for removal of the damper

without risk of structural damage or leakage (if the fireplace is factory

built) The appliance may NOT be installed into the fireplace.

WARNING

Direct-Vent Fireplace Insert Vent Requirements - Use liner

listed to UL181 (Factory-made Air Ducts And Air Connec-

tors) or UL1777 (Chimney Liners) for the AIR INTAKE. Use

liner listed to UL1777 ONLY for the EXHAUST.
Do not substitute the heat-rated flex liner (UL1777) for the

exhaust with any other type liner or a fire may result caus-

ing property damage, personal injury or loss of life.
