completely.

This Style Crest, Inc. replace and its com­ponents are safe when installed according
to this installation manual and operated as
recommended. Unless you use Style Crest,
Inc. components designed and tested for

this replace system, YOU MAY CAUSE A
SAFETY HAZARD!

The Style Crest, Inc. warranty will be voided
by, and Style Crest, Inc. disclaims any re­sponsibility for the following actions:

A) Modication to the replace, components,

doors, blower, fans or vent system.

B) Use of any component part not manu-

factured or approved byStyle Crest, Inc.
in combination with a Style Crest, Inc.

Proper installation is the most important step
in ensuring safe and continuous operation

of the replace. Consult the local building

codes as to the particular requirements
concerned with the installation of all factory

built replaces. This replace, when installed,

must be electrically grounded in accordance
with local codes or in the absence of local

SELECTING LOCATION

To determine the safest and most efcient
location for your replace, consider the fol-

lowing guidelines:

1. The location must allow for proper clear­ances (see Figure 1, page 6).

• Flush installation is recommended

where living space is limited.

• Projected installation may be ideal for a
new addition to an existing nished wall.

• Corner installation makes use of a space

that may not normally be used and pro-

vides a wider and more efcient range

for radiant heat transfer.

2. Consider a location where the replace

would not be affected by drafts, air con­ditioning ducts, windows or doors.

3. A location that avoids the cutting of joists
or roof rafters makes ventilation installa­tion easier.

In selecting a location, the following precau­tions must be observed:

• Do not connect this appliance to a chim-

ney system used for solid fuel burning

replace.

• Due to high temperatures, do not locate

this appliance in high trafc areas or near

furniture and draperies.

GENERAL VENTING

• If using a venting conguration of only

horizontal venting with no vertical run, a
1/4" rise for every 12" of run toward the
termination is required.

• There must not be any obstruction such

as bushes, garden sheds, fences, decks,
or utility buildings within 24" from the front
of the termination cap.

• Do not locate termination cap where exces­sive snow or ice build up may occur. Be
sure to clear vent termination area after
snow falls to prevent accidental blockage of
venting system. When using snow blowers,
do not direct snow towards vent termination
area.

VENT TERMINATION CLEARANCES

The nal position of your appliance depends

on the location of the vent termination in rela­tion to the clearances that must be observed
as shown in Figure 14, page 12.

You may avoid extra framing by positioning

your replace against an already existing
framing member. The back of the replace

may be positioned directly against a com­bustible wall.

Check with local codes. In the USA, follow the
current National Fuel Gas Fuel Gas Code,
ANS Z223.1 also known as NFPA 54.

These models are approved for use with
Style Crest, Inc. Series, rigid type direct vent
pipe as supplied by Style Crest, Inc. or with
approved types of exible vent pipe (not sup­plied) when appropriate sized for an 8" outer
and 5" inner diameter application.

Your replace is approved to be vented either

through the side wall, or vertically using the
following guidelines:

• Only use Style Crest, Inc. supplied or

approved types of venting components
or kits. Do not mix different types of vent
components, modify vent components or
custom fabricate vent components for use
in any one installation.

• Minimum clearance between vent pipes

and combustible materials is 1", except
where stated otherwise.

• Combustible material may be ush with
the top front of replace with a maximum

thickness of 3/4".

• Do not recess venting terminals into a wall

or siding.

• Do not install vent terminals below grade

level. Maintain a minimum height of 12"
above snow line.

• Do not terminate venting system into an

attic or garage.
