• It is very important to follow minimum clearances for

chimney connectors to combustibles such as walls and

ceilings when installing the stove near non-

combustible surfaces. Typical chimney connector

clearances are outlined below. The single wall

clearances are generic; the Double wall clearances are

for Simpson Dura Vent DVL, CHECK THE

SPECIFICATIONS FROM THE

MANUFACTURER OF YOUR CONNECTOR.

INSTALLING A VENTING SYSTEM

DO NOT CONNECT THIS UNIT TO ANY AIR

DISTRIBUTION DUCT OR SYSTEM

Secure all joints, including attaching the stovepipe to the

Fireplace Insert's flue collar, with three sheet metal

screws. Install #10 x 1/2" (3 mm x 13 mm) sheet metal

screws into the holes pre-drilled in the flue collar.

Leaving off the screws can cause joints to separate from

the vibration that results from a creosote chimney fire.

Long runs of stovepipe to increase heat dispersal are not

recommended. Using longer lengths of stovepipe or more

connecting elbows than necessary increase the chances of

draft resistance and the accumulation of creosote buildup.

Remember, the NFPA has recommended, minimum

clearances for chimney connectors to combustibles such

as walls and ceilings. Once the Fireplace Insert is

installed at safe distances from these combustible

surfaces, it is important to maintain these connector

clearances for the remainder of the installation.

CONNECTING YOUR WOOD FIREPLACE INSERT

You can install your Morgan to a prefabricated metal

chimney or a masonry chimney. See figure 7 to aid in

connections.

ONNECTING TO A PREFABRICATED METAL

CHIMNEY (A FULL FLUE LINER IS REQUIRED IN CANADA)

IT IS STRONGLY RECOMMENDED THAT THIS

FIREPACE INSERT IS INSTALLED WITH A

CONTINUOUS CHIMNEY LINER WITH A

MINIMUM DIAMETER OF 6” EXTENDING FROM

THE FIREPLACE INSERT TO THE TOP OF THE

CHIMNEY. THE CHIMNEY LINER MUST

CONFORM TO THE CLASS 3 REQUIREMENTS OF

CHIMNEY LINER STANDARDS CAN/ULC-S635 OR

CAN/ULC- S640

You can install the Morgan in a masonry or zero

clearance fireplace. Before installing the stove in a

factory-built fireplace, the fireplace must have the

following characteristics:

1. Listed per UL 127 or ULC S610.

2. Include a full height listed chimney liner meeting

type HT requirements (2100° Fahrenheit) per UL 1777

(United States) or ULC S635 (Canada) standards, or with

a direct flue connector into the first chimney liner section

3. The means to prevent room air passage to the

chimney cavity of the fireplace.

4. Does not disturb the airflow in or within the

fireplace when installed (louvers, or cooling air inlet or

outlet ports must not be blocked).

5. Not be altered in any way, except for the

following:

a. External trim pieces which do not affect

the operation of the fireplace can be removed, providing

they are stored on or within the fireplace for re-assembly

if the insert is removed.

b. The chimney damper can be removed to

install the chimney liner.

6. Must not have blocked circulating chambers (if

available).

7. The means for removing the insert to clean the

chimney flue.

8. Have a permanent metal warning label (provided with

the Morgan—see illustration to the below) attached to the

fireplace by riveting it to the outside wall, stating that the

fireplace must be restored to its original condition for safe

use without the insert.

Remember, you must adhere to all previously described

floor protection requirements when installing into a zero

clearance fireplace.

▌ WARNING:

DO NOT CONNECT THE FIREPLACE INSERT

TO A CHIMNEY FLUE SERVING ANOTHER

APPLIANCE.

Make sure the size of the chimney’s flue is appropriate for

the Morgan. The Morgan requires a 6" (152 mm) inside

diameter flue for new installations. A 6” diameter flue

provides adequate draft and performance. You can use an

8" (203 mm) diameter existing flue with a reducer. An

oversized flue contributes to creosote accumulation. (In

this case, bigger is NOT better.)

When purchasing a prefabricated chimney to install with

your Fireplace Insert, be sure to also purchase from the

same manufacturer the wall pass-through (or ceiling

support package), "T" section package, fire-stops (when
