COMBUSTIBLE MANTELS
Because of the extreme heat this fireplace emits, the mantel clearances are critical. Combustible mantel clearances from top of unit are shown
in the diagram below.
Note: A non-combustible mantel may be installed at a
lower height if the framing is made of metal studs
covered with a non-combustible board.
This drawing is to scale at 1:6 (one inch = 6 inches). Mantel
can be installed anywhere in shaded area or higher using the
above scale.
Note: Ensure the paint that is used on the mantel and the
facing is "heat resistant" or the paint may discol-
our.

able combustible finishing materials.
Note: The unit does not have to be com-
pletely enclosed in a chase. The
clearance on top of the unit is 0" to
the standoffs so combustible building
materials can be laid directly on top
of the standoffs. You must maintain
1-1/2" (38mm) clearance from the
vent to combustible materials for flex
(1-1/4" for Simpson Dura-Vent).
2) Frame in the enclosure for the unit with
framing material.

raGlow may be used for Flex instal-
lations.
VENTING
INTRODUCTION
The G33R-1 uses the "balanced flue" tech-
nology Co Axial system. The inner liner vents
products of combustion to the outside while the
outer liner draws outside combustion air into the
combustion chamber thereby eliminating the
need to use heated room air for combustion and
losing warm room air up the chimney.
There are 2 vent systems approved for use with
the G33R-1: the UltraGlow Direct Vent System
(Flex) for Horizontal Terminations only (see
pages 8 and 10), and the Simpson Dura-Vent
Systems for Horizontal and Vertical Terminations
(see pages 11-20).
Note: These flue pipes must not be con-
nected to any other appliance.
The gas appliance and vent system must be
vented directly to the outside of the building,
and never be attached to a chimney serving a
separate solid fuel or gas burning appliance.
Each direct vent gas appliance must use it's own
separate vent system. Common vent systems
are prohibited.
UNIT ASSEMBLY
PRIOR TO
INSTALLATION
The Top Facing Support, the Side Nailing Strips
and the 2 Top Standoffs must be correctly po-
sitioned and attached to the top before unit is
slipped into position.
Top Standoff Assembly
The top standoffs are shipped in a flat position
and must be pulled up and bent into the cor-
rect shape. Setup each of the 2 Top Standoff
by bending up at the bend lines until the screw
hole in the standoff and the pre-punched screw
holes on the top line up. Use three more screws
per standoff to attach securely to the top.
Top Facing Support & Side Nail-
ing Strips
Determine the total thickness of facing mate-
rial (e.g. drywall plus ceramic tiles) to allow the
finished surface to be flush with the front of the
unit. Total facing thickness can vary from 1/2"
(13mm) to 1-1/4" (32mm) thick.
The Top Facing Support & Side Nailing Strips can
be mounted in 3 different positions depending
on the thickness of the facing material.
2) Use the same screw hole position for the
Side Nailing Strips as was used for the Top
Facing Support. Attach each side nailing
strip using 3 screws.
*For "C" screw position the top facing
support is reversed.
1) Mount Top Facing Support using the 3
supplied screws into the three pre-punched
screw holes on the top front of the unit. Use
hole positions A, B, or C depending on your
facing depth.

RIGID PIPE VENTING
SYSTEMS
Horizontal or Vertical
Terminations
The Rigid Pipe Vent System offers a com-
plete line of component parts for installation
of both horizontal and vertical installations.
Many items are offered in decorative black,
as well as galvanized finish. We recommend
using the galvanized finish for installation
with the G33R-1.
The minimum components required for a basic
horizontal termination are:
1 AstroCap Horizontal Termination Cap
1 90oElbow
1 Rigid Pipe Adaptor
1 Wall Thimble
1 Length of pipe to suit wall thickness
(see chart)
For siding other than vinyl furring strips may
be used, instead of the vinyl siding standoff,
to create a level surface to mount the vent
terminal. The Terminal must not be recessed
into siding.
If a Vinyl Siding Standoff is required (it must be
used with vinyl siding), measure to outside sur-
face of wall without siding and add 2 inches.
INSTALLATION
PROCEDURES
for UltraGlow Direct Vent
System (Flex)
1) Locate the unit in the framing, rough in the
gas (preferably on the right side of the unit)
and the electrical (Junction block is on the
left side) on the left. Locate the centerline of
the termination and mark wall accordingly.
Cut a 10"(254mm) hole in the wall (inside
dimension).
*If this is an outside corner, the minimum distance
between the vent and the outside corner is 6"
(15cm) with AstroCap termination cap or 12"
(30cm) with Dura-Vent termination cap. See
"F" on the diagram on page 8.
Minimum and Maximum Vent Clearances
Note: A 1-1/2"(38mm) clearance around
the liner must be maintained except
that only a 1" (25mm) clearance is
needed at the termination end. We
recommend framing a 10"(254mm) x
10"(254mm) (inside dimensions) hole
to give structural rigidity for mounting
the termination.
Note: If installing termination on a siding
covered wall, furring strips must be
used to ensure that the termination
is not recessed into the siding.
2) Level the fireplace and fasten it to the fram-
ing using nails or screws through the nailing
strips.
3) Assemble the vent assembly by applying
Mill Pac to the 4"(100mm) inner collar of the
termination and slipping the 4"(100mm) liner
over it at least 1-3/8" (35mm). Fasten with
the 3 screws (drilling pilot holes will make this
easier). Apply Mill Pac or high temperature
silicone to the 6-7/8"(175mm) flex pipe and
slip it over the 6-7/8" outer collar of the vent
terminal at least 1-3/8"(35mm) and fasten
with the 3 screws.
4) Separate the 2 halves of the wall thimble and
securely fasten the one with the tabs to the
outside wall making sure that the tabs are
on top and bottom. Fasten the other thimble
half to the inside wall. The thimble halves
slip inside each other and can be adjusted
for 2 x 4 or 2 x 6 walls. The liners must slip
over the collars a minimum of 1-3/8".
5) Slip the assembled liner and termination
assembly through the thimble making sure
the termination cap faces up (there are
markings on the cap that show which way
is up). This will position the termination cap
Note: To make the installation more
aesthetically pleasing,
we recommend framing
out a square to mount
the terminal to.
INSTALLATION
with proper down slope for draining water.
Fasten the cap to the outer wall with the 4
supplied screws.
6) Pull the centre 4"(100mm) liner and outer
6-7/8"(175mm) liner out enough to slip over
the flue collars of the fireplace.
7) Apply Mill Pac over the fireplace inner collar
and slip the 4"(100mm) liner down over it
and attach with 3 supplied screws.
8) Do the same with the 6-7/8"(175mm) liner.
9) Apply a bead of silicone between the thimble
and termination and around the outer edge
of the terminal at the wall in order to keep
the water out.
IMPORTANT: Do not locate termination hood
where excessive snow or ice buildup may
occur. Be sure to check vent termination
area after snow falls, and clear to prevent
accidental blockage of venting system. When
using snow blowers, make sure snow is not
directed towards vent termination area.

HORIZONTAL
INSTALLATIONS
Install the vent system according to the
manufacturer's instructions included with the
components.
1) Set the unit in its desired location. Check
to determine if wall studs or roof rafters
are in the way when the venting system is
attached. If this is the case, you may want
to adjust the location of the unit. Rough in
the gas preferably on the right side of the
unit and the electrical (junction block is on
the left side) on the left.
2) Direct Vent pipe and fittings are designed
with special twist-lock connections to con-
nect the venting system to the appliance
flue outlet. A twist-lock appliance adaptor
is an available option that must be used in
conjunction with the Simpson Dura-Vent
Direct Vent GS system.
3) Put a bead of silicone inside the outer
section of the adapter and a bead of Stove
Mate on the inner collar. Slip the adapter
over the existing inner and outer flue collar
and fasten to the outer collar only with the
3 supplied screws (drilling pilot holes will
make this easier). Level the fireplace and
fasten it to the framing using nails or screws
through the nailing strips.
4) Assemble the desired combination of pipe
and elbows to the appliance adaptor and
twist-lock for a solid connection.
Note:
a) Twist-lock procedure: Four indentations,
located on the female ends of pipes and
fittings, are designed to slide straight
onto the male ends of adjacent pipes
and fittings, by orienting the four pipe
indentations so they match and slide
in to the four entry slots on the male
ends, Diagram 1. Push the pipe sections
completely together, then twist-lock
one section clockwise approximately
one-quarter turn, until the two sections
are fully locked. The female locking lugs
will not be visible from the outside, on
the Black Pipe or fittings. They may be
located by examining the inside of the
female ends.
Note: Apply sealant "Mill-Pac" to inner pipe
Diagram 1
and high temperature silicone seal-
ant to outer pipe on every twist-lock
joint.
Diagram 3
b) Horizontal runs of vent must be sup-
ported every three feet. Wall straps are
available for this purpose.
5) Mark the wall for a 10" x 10" square hole.
The center of the square hole should line
up with the centerline of the horizontal pipe.
Cut and frame the 10 inch square hole in
the exterior wall where the vent will be
terminated. If the wall being penetrated is
constructed of non-combustible material,
i.e. masonry block or concrete, a 7"(178mm)
diameter (7-1/2"(191mm) dia. for flex) hole
is acceptable. See Horizontal Termination
diagram on page 13.
Note: With Dura-Vent, the minimum height
is achieved by installing a 90oelbow
directly to the rigid pipe adaptor.
Note:
a) The horizontal run of vent must be level,
or have a
1/4 inch rise for every 1 foot of run to-
wards the termination. Never allow the
vent to run downward. This could cause
high temperatures and may present the
possibility of a fire.
b) The location of the horizontal vent termi-
nation on an exterior wall must meet all
local and national building codes, and
must not be blocked or obstructed. For
External Vent Terminal Locations, see
diagram on page 9.
c) Snorkel Terminations:
For installations requiring a vertical rise
on the exterior of the building, 14-inch
and 36-inch tall Snorkel Terminations
and the Riser Vent as shown in Dia-
gram 2 & 2a are available. Follow the
same installation procedures as used
for standard Horizontal Termination.
NEVER install the snorkel upside
down.
*As specified in CGA B149 Installation Code.
Local codes or regulations may require different
clearances.
Diagram 2
Below Grade Snorkel Installation
If the Snorkel Termination must be installed
below grade, i.e. basement application,
proper drainage must be provided to prevent
water from entering the Snorkel Termination.
Refer to Dura-Vent Installation instructions
for details. Do not attempt to enclose the
Snorkel within the wall, or any other type
of enclosure.
6) The arrow on the vent cap should be
pointing up. Insure that the 1-1/2" clear-
ances to combustible materials are main-
tained (Diagram 3). Install the termination
cap.
Diagram 2a
The four wood screws provided should
be replaced with appropriate fasteners for
stucco, brick, concrete, or other types of
sidings.
Note: If installing termination on a siding
covered wall, a vinyl siding standoff
or furring strips must be used to
ensure that the termination is not
recessed into the siding.
7) Before connecting the horizontal run of vent
pipe to the vent termination, slide the Wall
Thimble (Part # 620-926) over the vent
pipe.
8) Slide the appliance and vent assembly
towards the wall carefully inserting the
INSTALLATION

UltraGlow G33R-1 Zero Clearance Rear Vent Direct Vent Gas Fireplace 19
4) Assemble the desired lengths of pipe and
elbows. Ensure that all pipes and elbow
connections are in the fully twist-locked
position and sealed.
Note: Apply sealant "Mill-Pac" to inner pipe
and high temperature silicone seal-
ant to outer pipe on every twist-lock
joint.
Diagram 4
5) Cut a hole in the roof centered on the small
drilled hole placed in the roof in Step 2. The
hole should be of sufficient size to meet
the minimum requirements for clearance
to combustibles of 1-1/2". Slip the flashing
under the shingles (shingles should overlap
half the flashing) as per Diagram 3.
Diagram 3: The upper half of the flashing is
installed under the roofing material and not
nailed down until the chimney is installed. This
allows for small adjustments.
6) Continue to assemble pipe lengths.
Note: If an offset is necessary in the attic to
avoid obstructions, it is important to
support the vent pipe every 3 feet, to
avoid excessive stress on the elbows,
and possible separation. Wall straps
are available for this purpose.
Galvanizedpipeis desirableabove the roofline
due to its higher corrosionresistance. Continue
to add pipe sections through the flashing until
the height of the vent cap meets the minimum
height requirements specified in Diagram 4 or
local codes. Note that for steep roof pitches,
the vertical height must be increased. Apoor
draft, or down drafting can result from high
wind conditions near big trees or adjoining
roof lines, in these cases, increasing the
vent height may solve the problem.
7) Ensure vent is vertical and secure the base
of the flashing to the roof with roofing rails,
slide storm collar over the pipe section and
seal with a mastic.
8) Install the vertical termination cap by twist-
locking it.
Note: Any closets or storage spaces, which
the vent passes through must be
enclosed.

TERMINATION
1) Maintain the 1-1/2" clearances (air
spaces) to combustibles when
passing through ceilings, walls,
roofs, enclosures, attic rafter,
or other nearby combustible
surfaces. Do not pack air spaces
with insulation. Check pages
12-13 for the maximum vertical
rise of the venting system and
the maximum horizontal offset
limitations.
Diagram 4
vent pipe into the vent cap assembly. It is
important that the vent pipe extends into the
vent cap sufficient distance so as to result
in a minimum pipe overlap of 1-1/4 inches.
Secure the connection between the vent pipe
and the vent cap 3 sheet metal screws.
9) Install wall thimble in the center of the 10"
square and attach with wood screws (Dia-
gram 4).
2) Set the gas appliance in
its desired location. Drop a
plumb bob down from the
ceiling to the position of
the appliance flue exit, and
mark the location where the
vent will penetrate the ceiling. Drill a small
hole at his point. Next, drop a plumb bob
from the roof to the hole previously drilled
in the ceiling, and mark the spot where the
vent will penetrate the roof.
3) A Firestop spacer must be installed in the
floor or ceiling of every level. To install the
Firestop spacer in a flat ceiling or wall, cut
a 10 inch square hole. Frame the hole as
shown in Diagram 2 and install the fire-
stop.

GAS LINE
INSTALLATION
The gas line can be brought through either the
right or the left side of the appliance. The gas
valve is situated on the right hand side of the
unit and the gas inlet is on the right hand side
of the valve.
Note: If the gas line is being installed from
the left side, be sure to leave room to
accommodate servicing of the fan.
The gas line connection may be made of rigid
pipe, copper pipe or an approved flex connec-
tor. (If you are using rigid pipe, ensure that the
valve can be removed for servicing.) Since some
municipalities have additional local codes it is
always best to consult with your local authorities
and the CAN/CGA B149 installation code.
For USA installations follow local codes and/or
the current National Fuel Gas Code, ANSI
Z223.1.
When using copper or flex connectors use only
approved fittings. Always provide a union so
that gas lines can be easily disconnected for
servicing. Flare nuts for copper lines and flex
connectors are usually considered to meet this
requirement.
Important:Always check for gas leaks with a
soap and water solution or gas leak detector.
Do not use open flame for leak testing.
