Horizontal Installation

Standard Ceiling Installation

INSTALLATION

Note: Increasing the chimney height above

this minimum level will sometimes

help your unit to “breathe” better

by allowing a greater draft to be cre-

ated. This greater draft can decrease

problems such as, difﬁ cult start-ups,

back-smoking when door is open,

and dirty glass. It might be sufﬁ cient

to initially try with the minimum re-

quired height, and then if problems

do arise add additional height at a

later date.

4) Slide the roof ﬂ ashing over your chimney

and seal the ﬂ ashing to the roof with rooﬁ ng

compound. Secure the ﬂ ashing to your roof

with nails or screws.

5) Place the storm collar over the ﬂ ashing,

sealing the joints with a silicone caulking.

6) Fasten the raincap with spark screens (if

required) to the top of your chimney.

HOW TO DETERMINE IF

ALTERNATE

FLOOR PROTECTION

MATERIALS ARE

ACCEPTABLE

The speciﬁ ed ﬂ oor protector should be 3/8"

(18mm) thick material with a K - factor of

0.84.

The proposed alternative is 4" (100mm) brick

with a C-factor of 1.25 over 1/8" (3mm) mineral

board with a K-factor of 0.29.

Step (a):

Use formula above to convert speciﬁ cation

to R-value.

R = 1/k x T = 1/0.84 x .75 = 0.893.

Step (b):

Calculate R of proposed system.

4" brick of C = 1.25, therefore

Rbrick = 1/C = 1/1.25 = 0.80

1/8" mineral board of k = 0.29, therefore

Rmin.bd. = 1/0.29 x 0.125 = 0.431

Total R = Rbrick + Rmineral board =

0.8 + 0.431 = 1.231.

Step (c):

Compare proposed system R of 1.231 to

speciﬁ ed R of 0.893. Since proposed system

R is greater than required, the system is

acceptable.

FACTORY

BUILT CHIMNEY

When a metal prefabricated chimney is used, the

manufacturer's installation instructions must be

followed. You must also purchase and install the

ceiling support package or wall pass-through and

"T" section package, ﬁ restops (where needed),

insulation shield, roof ﬂ ashing, chimney cap,

etc. Maintain proper clearance to the structure

as recommended by the manufacturer. The

chimney must be the required height above the

roof or other obstructions for safety and proper

draft operation.

7) For optimum efﬁ ciency when installing into

a masonry chimney, size accordingly, i.e.

the 6" (152mm) ﬂ ue dia. is 28.28 sq.in.

8) To complete your chimney installation, install

the double wall connector pipe from the

stove’s ﬂ ue collar to the chimney support

device.

9) If you are using a horizontal connector,

the chimney connector should be as high

as possible while still maintaining the 18"

(457mm) minimum distance from the hori-

zontal connector to the ceiling.

10) NOTE: Residential Close Clearance and

Alcove installations require a listed dou-

ble wall connector from the stove collar

to the ceiling level.

The diagrams below illustrate one way to in-

stall your unit into a standard ceiling or with a

horizontal connector. Check with your dealer

or installer for information on other options

available to you.

STEP-BY-STEP

CHIMNEY AND

CONNECTOR

INSTALLATION

Note: These are a generic set of chimney

installation instructions. Always fol-

low the manufacturers own instruc-

tions explicitly. Check the Minimum

Recommended Flue Heights (Table

1).

1) With your location already established, cut

and frame the roof hole. It is recommended

that no ceiling support member be cut for

chimney and support box installation. If it is

necessary to cut them, the members must

be made structurally sound.

2) Install radiant shield and support from

above.

3) Stack the insulated pipe onto your ﬁ nish

support to a minimum height of 3 feet above

the roof penetration, or 2 feet above any

point within 10 feet measured horizontally.

There must be at least 3 feet of chimney

above the roof level.
