INSTALLATION REQUIREMENTS
GAS LINE INSTALLATION
IMPORTANT: Gas piping should be installed only by
trained and qualified technicians.
The appliance and its individual shut-off valve must be
disconnected from the gas supply piping system during any
pressure testing of that system in excess of 1/2” psi.
The appliance must be isolated from the gas supply piping
system by closing its individual shutoff valve during any
pressure testing of the gas supply piping system at test pressures
equal to or less than 1/2” psi.
The gas line can be brought through the left side of the
appliance. The 1/2” service gas line must connect to the
flexible appliance connector which is attached to the main
control valve. DO NOT MAKE THIS CONNECTION
UNTIL ALL PRESSURE TESTING OF THE GAS
PIPING SYSTEM IS COMPLETE. FAILURE TO
DO SO WILL RESULT IN DAMAGE TO THE
MAIN CONTROL VALVE.
Gas piping must conform to the current National Fuel Gas
Code, ANSI Z223.1.
Always consult with the local code official for additional local
codes applicable in your area.
IMPORTANT: Always check for gas leaks with a soap
and water solution or gas leak detector. Never use open
flame for leak testing.
NOTE: To properly check gas pressure, both inlet and
manifold pressures should be checked using the valve
pressure ports on the control valve.

VENTING PLANNING
The Alpine TR-36 uses Simpson Duravent Co Axial
venting systems. The inner tube vents products of
combustion away from the appliance, while the outer tube
draws outside air into the combustion chamber. This is a
closed system and uses no air from the interior of the home
for combustion.
Never attach this fireplace vent to another vent serving
another appliance. Each direct vent gas appliance must use
its own separate venting system. Common venting systems
are prohibited for use with this appliance.
Always vent the fireplace to outside of the building. Never
vent into a garage or enclosed area.
This venting system, in combination with the Alpine TR-
36 Direct Vent Gas Fireplace, has been tested and listed as
a direct vent heater by Intertek. The location of the
termination cap must conform to the requirement in the
Vent Termination Clearances diagram on page 10 of this
manual.
Before proceeding with installation, carefully examine the
chart on page 10 of this manual for options regarding
proper placement of the vent termination.
In all cases, adequate combustion and ventilation air must
be available for the fireplace. Never block the termina-
tion cap. Make sure foliage does not grow around the
termination cap. In all cases, follow the clearances listed
on page 8 of this manual.
NOTE: Never connect this gas appliance to a chimney
flue serving a separate solid-fuel burning appliance.

Alpine TR42 Direct Vent Gas Fireplace
VENTING
VENTING – HORIZONTAL
Install the vent system according to the instructions
included in the venting kit received with the fireplace.
1. With the unit in the desired location, check to determine
if wall studs or roof rafters will obstruct the venting system
when attached. If this is the case, you may want to adjust
the location of the unit or consult with your framing
contractor for options in adjusting the framing.
2. Determine where the horizontal vent pipe will exit
through the exterior wall. Frame a 10” x 10” opening at the
exit location and mount the horizontal firestop. This
firestop will assure that all clearances to the vent pipe are
maintained . (See fig. 10)
3. To properly assemble the Simpson Vent pipe a high
heat sealant , such as Mil-Pac or Dap High Heat Mortar,
should be used to ensure an airtight vent. Apply the sealant
to the inner collar of the pipe, line up the lugs on the out-
side of the pipe, slip the pipe together and then twist the
pipe to lock the lugs together (see fig 11). Wrap the outer
seam of the vent pipe with aluminum tape or seal with sili-
con.
Fig. 11 – Applying Sealant
NOTE: Clearances to combustibles from the vent pipe
must be adhered to. See the table below for proper
clearances.
Horizontal Venting Clearances
TOP OF PIPE 2” to combustibles
SIDES OF PIPE 1” to combustibles
BOTTOM OF PIPE 1/2” to combustibles
4. Install the vertical pipe needed, followed by the elbow to
achieve the pre-determined exit height and then extend the
horizontal section of vent through the pre-mounted
horizontal firestop. The pipe extending through the
exterior wall should not extend beyond the surface, which
the termination cap will be mounted to, more than 1” but
needs to be at least flush with this surface ( see fig. 12).
5. Carefully slide the vent termination over the vent pipe
from the outside and flush it up against the exterior wall.
Level the termination cap for appearance sake, making sure
the arrow is pointing upward on the termination cap (see
fig. 13). Carefully fasten the termination cap to the exterior
wall (see fig. 14) using the screws provided in the
termination box. You may seal around the termination cap
with a quality silicone for insulation purposes.
NOTE: All pipe joints must be sealed with Mill-pac or
Dap High Heat Mortar on the inner pipe and aluminum
tape or Silicone on the outer joint.

1. Maintain the 1-1/2” clearances to combustibles
when passing through ceilings, walls, roofs, enclosures,
attic rafters, or other nearby combustible surfaces. See the
diagrams on page 13 of this manual for the maximum
vertical rise of the venting and the maximum horizontal
offset limitations.
2. With the gas appliance in its desired location,
drop a plumb bob 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 this 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. Determine if ceiling joists,
roof rafters, or other framing will obstruct the venting
system. You may choose to relocate the fireplace or offset
the venting to avoid cutting framing members (see figure
16).
Firestop
Flashing
Fig. 15– Vertical Venting
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 (Figure 17) and install the firestop.
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 with Mill-pac brand sealant on
the inside collar and aluminum tape on the exterior. An air
tight seal must be created.

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”.
6. Continue to complete the assembly of the pipe lengths.
See (figure 18) for proper vent height projecting through
the roof.
7. Ensure that the vent is vertical and secure the base of the
flashing with roofing nails. Slide the storm collar over the
pipe section and seal with a mastic type sealant.
8. Install the vent cap by twist locking it in place.

Flex vent may be used in a number of basic installations to simplify the
installation process. It must be noted that the use of flex vent increases
the height of the ceiling (as shown in the illustration below right) by
6”. It also needs to be noted that all firestopping practices must be
adhered to with flex venting also.
It is recommended that a high temperature sealant such as Mill Pac or Dap
High Heat Mortar be used to seal the center flex liner to the appliance
vent nipple as well as the vent nipple on the termination cap. Aluminum
tape or silicone is recommended to seal the outer flex liner to the appli-
ance and to the vent termination. All four points of connection should be
fastened with a band clamp.
As noted in the venting chart below, there must be a minimum of 1’ of
vertical rise before the transition into the horizontal run. 1’ of vertical
rise will provide a maximum of 2’ horizontal run, which will accomplish
most exterior wall applications. 2’ of vertical rise will accommodate up to
3’ of horizontal run, which is the maximum horizontal run allowable with
flex vent. Only one 90° transition may be used with the flex vent taking it
from the vertical to the horizontal. Offsetting in the horizontal plane is not
allowed.

There are spacers Provided to maintain the orientation between the
two liners. The spacers need to be utilized at the beginning and the
end of a 90° transition and also at 12” intervals during the horizontal
run of the flex vent. ( see below)
The maximum horizontal run may be 3’ with a minimum vertical rise of
3’ as shown in the chart below. A maximum vertical run of 8’ may be
utilized. If your vertical run is greater than 3’ you may incorporate up to
two bends into the vertical run. The bends must not exceed 45°.
