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

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”.

Termination Cap
To install the termination cap, slide the cap vent
sections into the vent sections as shown in Figures
10A and 10B. Secure the cap flush to the wall
using the eight 1" fasteners provided. Seal the cap
to the wall with a mastic such as silicone caulking.
Fasten the inner vent with three 1/2" screws to
secure the vent. (An optional CS cap shield is
required if the cap is located in an area of easy
accessibility. See Figure 11.) Vent termination
must not be recessed into the wall or siding.
Be sure to follow all termination cap location minimum dimensions that have been discussed on the
previous page.
Skip section B below and continue with Step 4 on
page 13.
B. Vertical Termination
When planning your fireplace location, the vent system construction and necessary clearances must be
considered. The following figures are the maximum
distances from the base of the unit, as well as the
minimum air space clearances that must be maintained: Maximum straight unsupported rise - 25 feet;
maximum horizontal unsupported run - 3 feet; air
space clearances around vertical venting - 1" on all
sides; air space clearances around horizontal venting
- 3" on top and 1" on sides and bottom; maximum
height - 40' from the base of the unit. Every 1' of horizontal run requires at least 2' of vertical rise.
(Example: a 12' overall installation height may be offset as much as 6' horizontally.) The maximum is 20
feet.
1. Assembling vent sections. Attach either a
15942B (starter elbow) 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 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. To bypass any overhead
obstructions, the vent system may be offset using
a 90° elbow (VK5) or a 45° elbow (EL45). Vent
stabilizers (VS4) have straps for securing these
parts to joists or rafters. Plumbers tape may be
purchased locally and used in conjunction with
vent stabilizers. See Figure12.

2. Preparing the ceiling for firestop spacers.
Mark and cut out an opening in the ceiling for the
firestop spacer. Frame the opening with the same
size lumber used in the ceiling joists. Unless the
flue if offset, frame the 10" x 10" opening directly
over the firebox.
3. Installing the firestop spacers. Firestop spacers must be used whenever the venting penetrates
a ceiling/floor area.
In all situations, firestop spacers are to be nailed to
the ceiling joists from the bottom or fireplace side,
EXCEPT when the space above is an insulated
ceiling or attic space. In this situation, the firestop
spacer must be nailed from the top side to prevent
loose insulation from falling into the required one
inch air space around the vent system. See Figure
13.
Install the firestop spacer (FS6) by positioning and
nailing the four sides of the firestop spacer to the
joists using a minimum of three nails per side.
4. Securing vent system. Continue assembling
the vent sections up through the firestop spacers
as needed. vent sections must be locked into position with the screws provided, using the predrilled
holes. The 15942B starter elbow and the vent stabilizers have straps for securing these parts to
joists or rafters.
Note: Be sure to provide intermediate support for the vent during construction and
check to be sure inadvertent loading has
not dislodged the vent from the appliance
or any vent joint.
Figure 13
Installing the firestop spacer
6. Marking the exit point in the roof. L o c a t e
the point where the venting will exit the roof by
plumbing down to the center of the vent. Drive a
nail up through the roof to mark the center. See
Figure 15.
7. Cutting out the hole in the roof. Measure to
either side of the nail and mark the 10" x 10" opening required. This is measured on the horizontal;
actual length may be larger depending on the pitch
of the roof. Cut out and frame the opening. See
chapter 25 of the Uniform Building Code for Roof
Framing details. A one inch minimum air space
clearance must be maintained between the chimney section and the roof.
8. Install roof flashing or site-produced chase
top. Position a roof flashing or a site-produced
chase top and secure in place with nails.
9. Assembling vent sections. Continue to add
vent sections through the roof opening, maintaining
at least a one inch air space clearance. If a specific height is desired, the chimney sections may
have to be cut (using shears) to a certain length.

A. STANDING PILOT OPERATION
1. Initial and Seasonal Lighting Procedure. Initial
lighting constitutes the first time the appliance has
been lit after installation. Seasonal lighting refers to
lighting the appliance after it has been unused and
the gas valve has been turned to OFF.
Be sure the remote wall switch and the gas knob
(located behind the lower access panel) have been
turned to the OFF position. See Figure 35. Also,
your unit may have a rocker ON/OFF switch
installed inside the lower panel; it if does, this also
needs to be turned to the OFF position. If they are
not, do so and allow the appliance to sit for five minutes so any gas that may have accumulated in the
main burner compartment escapes.
Turn the manual on/off valve to ON. Turn the gas
knob to PILOT, as shown in Figure 36, and press in.
While holding it in, light the pilot by pressing the red
ignitor button, shown in Figure 37, several times until
the pilot ignites. Continue to hold in the gas knob for
about one minute after the pilot is lit. Release the
gas knob. The pilot should remain lit. If it goes out,
turn everything to the OFF position, let it sit for five
minutes and repeat this step again.
When the pilot remains lit, turn the gas knob to the
ON position. See Figure 38. You may now turn the
remote wall switch to the ON position which will turn
on the main burner. Initially, the flames may resemble more of a blue color but after the first 20 minutes
of operation, they will become more yellow.
Note: When first operated, this unit may release
an odor for the first several hours. This is caused
by the curing of the paint and the burning off of
any oils remaining from manufacturing.
Note: Keep the area near the appliance
clear and free from combustible materials,
gasoline and other flammable vapors and
liquids.

B. ELECTRONIC IGNITION OPERATION
1. Initial and Seasonal Lighting Procedure.
Initial lighting constitutes the very first time the
appliance has been lit after installation. Seasonal
lighting refers to lighting the unit after it has been
unused and the gas valve has been turned to OFF.
Be sure the remote wall switch and the manual
on/off knob have been turned to the OFF position.
Also, your unit may have a rocker ON/OFF switch
installed inside the lower panel; if so this also
needs to be turned to the OFF position. If they are
not, do so and allow the appliance to sit for five
minutes so any gas that may have accumulated in
the main burner compartment escapes.
Turn the manual on/off knob inside the lower
access area to the ON position. Then, turn the
remote wall switch to ON. This will activate an
electronic spark. Initially, the flames may have
more of a blue color but after the first 20 minutes of
operation, they will become more yellow.
2. Seasonal Shutdown. When the burning season comes to an end, the entire system should be
shut down. Note: There may be a rocker switch
on a column in the control area, as well as a
wall switch. Both have to be off for the unit to
be off. In this way, no gas will be running to the
appliance while it is not in use.
To shut down the appliance for an extended period
of time, you must first shut off the main burner by
moving the remote wall switch to the OFF position.
The next step is to remove the lower access panel
to expose the valve area. Locate the gas valve
knob and turn it to the OFF position. Turn the
manual on/off knob to OFF. Your entire system is
now shut down.
3. Lighting Procedure During Regular Use.
Simply turn the wall switch to the ON position.
This will activate the ignitor and the main burner
will light.

VII. MAINTENANCE INSTRUCTIONS
Cleaning the burner and control compartment
Keep the burner and control compartment clean by brushing and
vacuuming at least once a year. Always turn off the gas valve and
the ON/OFF switch before cleaning.
Checking flame patterns
Visually check the flame of the burner periodically, making sure the
flames are steady; not lifting or floating. The flame color should be
blue with yellow tips. The ignitor (electronic) or thermopile (standing pilot) tips should be covered with flame. See Figures 41
through 44.
Venting system inspection
The appliance and venting system should be inspected before use,
and at least annually, by a qualified field service person, to ensure
that the flow of combustion and ventilation air is not obstructed.
Cleaning the glass
Note: When cleaning the glass, NEVER use abrasive
materials. NEVER clean glass when hot. Keep pets
and children a safe distance away.
It is recommended to wear gloves while handling or removing
glass. DO NOT REMOVE GLASS WHEN HOT.
Clean glass after initial one hour burn. This is to remove any film
that develops from oils and log burn in time. After initial cleaning,
clean as needed.
To remove the glass for cleaning, follow Step 11 on page 16.
Handle glass panel with care to avoid striking or scratching it on
hard objects.
To clean the glass, use a non-abrasive automotive rubbing compound and glass cleaner. Simply apply an adequate amount to
the glass and wipe off per manufacturers instructions. Contact
your local stove shop or fireplace accessaries store for further recommendations.
Never operate this appliance without the glass properly secured in
place or if the glass is broken.
In the event of glass breakage, follow glass removal instructions
to remove the top retaining strip. Remove lower retaining strip in
the same manner. This will allow the removal of all glass fragments and sheet metal edge protection strips. Vacuum all
remaining glass pieces with a shop vac. (DO NOT VACUUM IF
PIECES ARE HOT.) Replace glass only with Heatilator part number 15573 ordered direct or through your local distributor. Never
use substitute material. Only fully tempered soda lime safety
glass or optional ceramic glass may be used on this appliance.
Log cleaning
Logs can be easily lifted out of position. Carbon build-up can be
removed with a vacuum cleaner.
To prevent the possibility of soot, we have provided your fireplace
with an adjustable air shutter. Your air shutter is provided in an
open position to ensure clean operation under normal situations.
In the even that soot is accumulating in your appliance, the air
shutter should be opened farther as shown in Figure 44. This can
be done with a screwdriver or a 1/4” wrench. Also, ensure logs
are positioned correctly to minimize flame contact with the logs.
