IV. PRE-INSTALLATION PREPARATION

A. GAS PRESSURE

For natural gas, the minimum inlet gas supply pressure is

4.5 inches water column, and the maximum inlet gas pres­sure is 7.0 inches water column, for the purpose of input
adjustment. Input rate is 22,500 Btu/hr. For propane gas,
the inlet gas supply pressure must be at least 11.0 inches
water column and a maximum 14.0 inches water column.
(See CKP Natural Gas to Propane Gas Conversion Kit
installation instructions.)

A 1/8" NPT plugged tapping is provided on the gas control
valve, near the outlet to the main burner immediately
upstream of the gas supply connection to the appliance,
accessible for a test gage connection .

Optimum manifold pressure is 3.5 inches water column for
natural gas and 10.5 inches water column for propane gas.

C. FIREPLACE LOCATIONS AND

SPACE REQUIREMENTS

This appliance may be installed along a wall, across a
corner or use an exterior chase. The GC150 Series
may be installed at a height level with the floor, or it
can be raised up from the floor to enhance its visual
impact. Figure 1 illustrates a variety of ways the
appliance may be located in a room. These appli­ances are also certified for installation in a bedroom
or bed/sitting room in the U.S.

B. HIGH ALTITUDE INSTALLATION

For U.S. installation, units are tested and approved for ele­vations from 0-2000 feet.

When installing this unit at an elevation above 2000 feet,
United States codes require a decrease of the input rating
by changing the existing burner orifice to a smaller size.
Input should be reduced 4 percent for each 1000 feet
above sea level. Check with the local gas utility for proper
orifice size identification. This unit uses a .093in. /2.36
mm. orifice size on natural gas versions and a .056 in./1.42
mm. orifice size on propane gas converted versions.

Consult your local gas company for assistance in determin­ing the proper orifice for your location or refer to ANSI
Z223.1-latest edition, Appendix F.

CAUTION:

DO NOT EXPOSE THE UNIT TO THE

ELEMENTS (SUCH AS RAIN, ETC.).

D. CLEARANCES

The following clearances to combustibles must be
maintained: Minimum clearances to the top standoffs
of the unit - 0", floor - 0", back - 1/2", sides - 1/2", top
of the hood to ceiling - 30". Minimum clearances to
venting are as follows: Horizontal runs require a 3"
minimum air space on the top and a 1" minimum air
space on the sides and bottom of the vent section.
Vertical rise sections require a 1" minimum air space
completely around the vent sections.

Figure 2a

Framing the Fireplace

F. FINISHING MATERIALS

Only non-combustible materials may be used to
cover the black surfaces of the fireplace front.

Combustible Finishing Material. Material made of
or surfaced with wood, compressed paper, plant
fibers, plastics, or any material capable of igniting
and burning, whether flame proofed or not, plastered
or unplastered.

Non-combustible Finishing Material. Material
which will not ignite and burn. Such materials are
those consisting entirely of steel, iron, brick, tile, con­crete, slate, glass or plasters, or combination thereof.

High Temperature Sealant Material. Sealants that
will withstand high temperatures (300° F+); General
Electric RTV103 (Black), or equivalent. Rutland, Inc.
Fireplace Mortar #63, or equivalent.

After completing the framing and applying the finish­ing material (dry wall) over the framing, a non-com­bustible sealant, one-half inch wide maximum, must
be used to close off any gaps at the top and sides
between the fireplace and facing to prevent cold air
leaks. See Figure 3.

Figures 2 and 2a show a typical framing of this fire­place assuming combustible materials are used. All
required clearances to combustibles around the fire­place must be adhered to. A 1/2" air clearance must
be maintained at the back and sides of the firebox
assembly. A minimum of 38” is required to the bot­tom of a 7” mantle. Anything greater than 7” must be
42” above the base of the unit. Any framing on top of
the fireplace must be above the top standoffs. Vent
sections for a horizontal run require a 3" minimum air
space on top and a 1" minimum air space on the
sides and bottom. Vertical rise sections require a 1"
minimum air space completely around the vent sec­tions.

V. STEP-BY-STEP INSTALLATION OF

THE FIREPLACE SYSTEM

WARNING!

BEFORE STARTING, DO THE FOLLOWING:

1. WEAR GLOVES AND SAFETY GLASSES FOR PROTECTION.

2. KEEP HAND TOOLS IN GOOD CONDITION. SHARPEN CUTTING EDGES AND MAKE SURE TOOL
HANDLES ARE SECURE.

3. ALWAYS MAINTAIN THE MINIMUM AIR SPACE REQUIRED TO THE ENCLOSURE TO PREVENT FIRE.

STEP 1 - Positioning the Firebox

This fireplace may be placed on a smooth combustible or non­combustible continuous, flat surface. When the appliance is

installed directly on carpeting, tile or other combustible material
other than wood flooring, the appliance shall be installed on a
metal or wood panel extending the full width and depth of the appli­ance.

Slide the unit into position and level the fireplace from side­to-side and front-to-back. Shim with non-combustible material,
such as sheet metal, as necessary.

Secure the fireplace by bending out the nailing flanges located on
each side of the fireplace and nailing the unit to the framing. See
Figure 4.

STEP 2 - Termination

Two types of termination are available for this appliance, horizon­tal and vertical. For vertical termination, skip section A and
advance to section B on page 11.

A. Horizontal Termination

Minimum combustible clearances to the vent on a horizontal run
is 3" on top and 1" on the bottom and sides. These clearances
must be maintained at all times. The maximum horizontal run
allowed for venting is 26 feet. The maximum vertical rise allowed
for horizontal termination is 25 feet. See Figure 5.

1. Assembling vent sections. Attach either a VE12 (starter
elbow), VE16, VE20 or straight vent section (depending upon
your specific installation) to the top of the appliance. Secure
with the three screws supplied. Use only vent supplied and
listed for use with this appliance and the appropriate number of
direct vent sections. MAINTAIN MINIMUM CLEARANCES
OR GREATER AROUND THE VENT SYSTEM. Do not pack
air spaces with insulation or other material.

a. Using elbows. The first elbow used with horizontal termi­nation must be starter elbow 15942. The maximum horizontal
distance this vent system may reach is 26'. No more than 3
elbows may be used. A single vertical-to-horizontal elbow is
already calculated into the allowable 26' run. Each additional
elbow reduces the maximum horizontal distance by three feet.
Example, by using three total elbows, the maximum horizontal
distance has been reduced to twenty feet (3 - 1 = 2 elbows X 3'
= 6'; 26' max. - 6' of elbows = 20' of horizontal run).

A B

Figure 4

Nailing Flanges

Figure 5 - Horizontal Length

Note: The horizontal run of vent must have a
1/4" rise for every 1 ft. of run towards the ter­mination. Never allow the vent to run down­ward. This could cause high temperatures
and may present the possibility of a fire.

1-99 8 21322L

b. Amount of venting required. Due to the many
different combinations that can be used when con­structing venting, the number of vent sections
required can only be determined by the installer.

1-99 9 21322L

GC150 SERIES DIRECT VENT GAS APPLIANCE

4. Venting through the wall. Horizontal venting

must terminate within the shaded area shown in
Figure 5 on the previous page. For example, if
your vertical rise is the minimum one foot, venting
can terminate anywhere between 16 inches and 3
feet.

The last section of vent may require cutting, depend-

ing upon wall thickness and appliance location. The
end of the vent must penetrate the exterior wall. Cut
the pipe so the outer vent section extends past the
exterior wall by 1" and the inner vent section extends
past the exterior wall by 21⁄2". See Figure 8.

2. Preparing the wall for interior wall shield. A
hole measuring 10" wide X 12" high must be cut

and framed in the exterior wall where venting will

be terminated. If the wall being penetrated is con­structed of non-combustible material, i.e. masonry
block or concrete, a 9" diameter port is accept­able.

The hole must be positioned so the vent system
will have a 1/4" rise for every 12" of run AND be

perpendicular to the wall. See Figure 6. The
height of the hole must be located to meet all local
and national codes and not be easily blocked or
obstructed. The minimum height to the top of the

exterior wall hole is 45” from the base of the unit.

This figure will increase by the length of each verti-

cally positioned vent section added to the venting
system.

3. Interior Wall Shield. An interior wall shield
must be installed each time the venting system
penetrates a wall. This shield has been designed
to maintain the minimum clearances needed for

the venting system and prevent cold air infiltration.

After the venting hole has been cut and framed,
secure an interior wall shield into position with four
1" fasteners, one in each corner. Bend out the
tabs located on the inner portion of the wall shield
and use a 1/2" screw to secure each tab to the
penetrating pipe. See Figure 7. (1/2" screws are
used to avoid penetrating the inner pipe.)

Note: Horizontal runs will require the use of
one Vent Support (VS4) for every 3' of vent.

Note: Exterior wall thickness must be a min­imum of 4" to a maximum of 231⁄2”.
