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).

• 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.

SAFETY

DANGER: Carbon monoxide poisoning may lead to death!

This replace must be installed by the O.E.M. builder or by a qualied (certied or licensed)

service person. It has a sealed gas combustion chamber that uses a coaxial pipe (pipe within a
pipe and having the same center) venting system. It brings in fresh air for combustion through
the outer pipe and combustion gases are exhausted through the inner pipe. If the glass door
assembly and venting pipe are not properly seated, connected and sealed, carbon monoxide
leakage (spillage) can occur.

Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning resemble the u,
with headaches, dizziness or nausea. If you have these signs, the replace may not be work-

ing properly. Get fresh air at once! Have replace serviced. Some people are more affected
by carbon monoxide than others. These include pregnant women, people with heart or lung

disease or anemia, those under the inuence of alcohol and those at high altitudes.

Propane/LP & Natural Gas: Propane/LP and natural gas are odorless. An odor-making agent
is added to the gas. The odor helps you detect a gas leak. However, the odor added to the
gas can fade. Gas may be present even though no odor exists.

Make certain you read and understand all warnings. Keep this manual for reference. It is your
guide to safe and proper operation of this replace.

WARNING: Any change to this replace or it’s controls can be
dangerous. Do not modify this replace under any circumstances.
Any parts removed for servicing must be replaced prior to operat­ing replace.

WARNING: Do not use a blower insert, heat exchanger insert or
other accessory not approved for use with this replace.

WARNING: This appliance is only for use with the type of gas
indicated on the rating plate. This appliance is not convertible for
use with other gases unless a certied kit is used.

WARNING: Do not allow fans to blow directly into the replace.

VENT TERMINATION CLEARANCES

Final position of your replace depends on

location of the vent termination in relation to
clearances that must be observed as shown
in Figure 5 on page 8.

The vent system serves as the “chimney” as
well as combustion air supply (air intake).
The horizontal run must have a rise of 1/4"
(0.6 cm) for every 12" (30.48 cm) of horizon­tal run towards the termination. Maximum
horizontal run depends on vertical rise from

replace adapter collar to vent termination

(see table below).

in stall vent termination. Depending on

location of your replace, you will vent

vertically or horizontally.

4. Allow 1" of pipe to protrude from internal
wall, depending on wall thickness. See
Figure 7, page 11.

INSTALLATION

Continued

5. For horizontal installation, an optional
siding standoff may be installed between
vent cap and exterior wall. Secure horizon­tal vent cap to standoff. Secure standoff/
vent cap assembly to wall (see Figure 7).
Do not seal termination to vent pipe. Vent
termination must be removable for service
pipe inspection.

6. For vertical installation, a vertical termi­nation is available. A vertical ue restric­tor must be installed into inner collar of

replace as shown in Figure 6, page 10.

When installing a length of pipe for vertical

termination that is over 3 ft., support pipe
every 3 ft. using metal wall straps. Vertical
to horizontal pipe must be kept at a 1 ft. to
4 ft. ratio with a maximum run of no more
than 20 ft.

If an offset is necessary in attic to avoid

obstruction, it is important to support vent
pipe every 3 ft. to avoid excessive stress
on elbows and possible separation (see
Figure 8).

Horizontal Termination Congurations

Figures 9 through 13 show different con-

gurations and alternatives for venting with
horizontal termination. Each gure includes

a chart with critical minimum and maximum
dimensions which MUST be met. IMPOR-
TANT: Remember that a horizontal run of
venting must have a 1/4" rise for every 12" of
run toward termination.

WARNING: Never run vent

downward as this may cause

excessive temperatures which
could cause a re. Operation of
improperly installed and main­tained venting system could
result in serious injury, property
damage or loss of life.

GROUND FLOOR INSTALLATION

Recommended Applications:

• Installation using cabinet surrounds

• Through the wall using round or square

termination (up to 12" horizontal pipe)

• NOT FOR CORNER INSTALLATION
