DERATING THE BURNER
The fireplace has been designed to operate at elevations
approximately 4500 ft. above sea level. No deration of
the burner needs to occur unless the fireplace is installed
at elevations below 2500 ft. or above 6500 ft. The burner
orifice should then be adjusted one drill size smaller for
higher elevations and one drill size larger for lower
elevations.
INSTALLATION REQUIREMENTS
3) If the appliance is to be installed on carpeting,
combustible vinyl tiling, or any other combustible
surface other than wood flooring, a 1/2” wood panel
must be installed on top of the existing flooring. The
panel must extend the full width and depth of
appliance.
4) The ASC-42 fireplace can be installed into many
different applications. See Figure 1 for examples.
5) Lay out fireplace dimensions on installation site
before proceeding with installation. This will ensure
proper clearances and assist in identifying potential
problems before installation.
6) Make sure to review the vent termination system
requirements before proceeding.
Fig. 1 – Installation Placement Options
LOCATING THE FIREPLACE
1) When selecting a location for your Gas Fireplace,
ensure that the clearances outlined in this manual are
adhered to strictly.
2) The fireplace must be installed on a flat, solid,
continuous surface. If the appliance is to be raised
off the floor on a platform, it must be securely
fastened to a sturdily constructed platform.
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 pip-
ing 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 must 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 CONNEC-
TION UNTIL ALL PRESSURE TESTING OF THE
GAS PIPING SYSTEM IS COMPLETE. FAILURE
TO DO SO WILL RESULT IN DAMAGE TO THE
MAIN CONTROL VALVE.
( Continued on next page )

Alpine Supply Company 42 Direct Vent Gas Fireplace
INSTALLATION REQUIREMENTS
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.
The manifold pressure is controlled by a regulator built
into the gas control, and should be checked at the
pressure test point.
1) Make sure the valve is in the “ OFF” position.
2) Loosen the “IN” and/or “OUT” pressure tap(s),
turning counterclockwise with a 1/8” wide flat
screwdriver.
3) Attach manometer to “IN” and/or “OUT” pressure
tap(s) using a 5/16” ID hose.
4) Light the pilot and turn the valve to the “ON”
position.
5) The pressure check should be carried out with the unit
Burning and the setting should be within the limits
specified on the safety label.
6) When finished reading the manometer, turn off the gas
Valve. Disconnect the hose and tighten the screw
(clockwise) with a 1/8” flat screwdriver. Note: screw
should be snug. But do not over tighten
CLEARANCES
IMPORTANT: Clearances listed in this manual must
be adhered to strictly. Failure to maintain these listed
clearances of the fireplace and venting system can re-
sult in a house fire.

3) If the fireplace is to be installed into an exterior wall.
The enclosure or fireplace chase should be insulated
to the same degree as the home. Check with your
local building official for any additional local
requirements (e.g. vapor barriers, drywall).
NEVER INSULATE THE FIREPLACE ITSELF
4) The top of the fireplace should be no closer than 18”
With Simpson Duravent pipe, or 21” with flex pipe
to the ceiling.
NOTE: The fireplace does not have to be
completely enclosed in a chase. The clearance on
the top of the fireplace is 0” to the spacers. You
must maintain clearance from the vent
components to combustibles.
IMPORTANT: The header above the framed
opening must be placed upright so as to allow for
proper clearance of the vent pipe. See figure 6.
FRAMING & FINISHING
1) Determine the total thickness of the facing material
(e.g. drywall plus ceramic tiles) to allow the finished
surface to be flush with the front of the unit. The
ASC-42 series may be installed with the facing
material adjacent to the finished flange.
Fig. 4 – Facing Options
2) Frame in the enclosure for the fireplace. A rough
framed opening of 33” high by 38” will be required
for installation (see figure 5-7).

VENTING PLANNING
The ASC-42 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 the outside of the building.
Never vent into a garage or enclosed area.
This venting system, in combination with the ASC-42
Direct Vent Gas Fireplace, has been tested and listed as a
direct vent gas fireplace heater by I.T.S. The location of
the termination cap must conform to the requirement in
the Vent Termination Locations diagram on page 8 of
this manual.
Before proceeding with installation, carefully examine
the chart on page 8 of this manual for options regarding
proper placement of the vent termination.

ELECTRICAL SYSTEM
INSTALLING ELECTRICAL CONTROLS
AND WIRING
A 110 volt power supply (grounded) is required to
operate the optional blower system. The blower
controller (optional) should be mounted in a wall within a
few feet of the appliance, in a convenient location. Once
the location of the blower controller has been identified,
mount a metal or plastic electrical box and route the
wires from the blower to the electrical box. The wiring
needs to be routed from the control location to the
appliance. The appliance internal electrical box is located
on the right side of the appliance. (See figure 9). Use only
Blower Kit #431917 Installation instructions for the
blower kit are included with the kit.
NOTE: even if the blower is not purchased with the unit,
it is still a good idea to hardwire the appliance in case the
fan is installed at a later date. DO NOT LEAVE THIS
CONNECTION LIVE UNTIL THE FAN IS
INSTALLED.
Fig. 9 – Typical Electrical
NOTE: Proper grounding must be maintained on the
appliance and on the blower assembly.
NOTE: Do not allow any wiring to rest against the
appliance as fire danger may result.
NOTE: DO NOT connect any electricity to the main
gas control valve wiring. Valve damage will certainly
occur.
The appliance is equipped with a millivolt system that
controls the main gas control valve. A low voltage two
strand wire set needs to be routed from the main gas
control valve to the desired position of the wall switch.
Some prefer the switch be co-located with the blower
controller. If this choice is made, a DIVIDED double
gang electrical box must be installed. (A standard (non-
divided) double gang box cannot be used.)
When installing the low voltage wiring. It is essential that
the wires be marked so as to never have 110 volt /24 volt
power attached to them. If power is attached to the
control valve, damage will certainly occur.
The appliance generates the millivoltage needed to
operate the gas control system. A standard wall toggle
switch or a listed wall thermostat may be used to control
the main gas valve.
The millivolt system has limitations on the distance it can
be installed from the fireplace. The greater the distance
from the fireplace, the larger the wire size must be to
prevent loss of the millivoltage. See the table below for
recommendations.
Maximum Length Wire Guage
9’ 22 ga.
13’ 20 ga.
20’ 18 ga.
30’ 16 ga.
50’ 14 ga.
Millivolt thermostats and remote controlled millivolt
thermostats are available from your Alpine dealer.
See figures 10, 11 and 12 for additional information
about wiring your appliance.
Note: Local codes need to be followed when installing
any electrical appliance. If conflicts between this
manual and local electrical codes exist. Local codes
always prevail.

INSTALLATION INSTRUCTIONS
SECURING THE FIREPLACE
The Fireplace is equipped with four nailing tabs, which
Must be bent out before inserting into framed opening
(See Figure 13)
Fig. 13– Securing the fireplace
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. To properly assemble the Simpson pipe and fittings on
a direct vent system, Mill-pac brand sealant must be
placed between the inner collars of the pipe (see figure
14). Slip the pipe together and twist to lock. After the
pipe is assembled. Carefully wrap the outer seam with
aluminum tape (or seal with silicone). An airtight seal
must be created.
NOTE: All pipe joints must be sealed with Mill-pac
sealant and aluminum tape or Silicone.
Fig. 14– Applying Sealant
NOTE: Horizontal runs must be supported every
three feet. Wall straps should be used for this support.
3. A 10” x 10” square hole must be cut in the exterior
wall. The centerline of this hole should align with the
centerline of the horizontal pipe. Cut and frame the 10”
hole to support the venting (see figure 24).
NOTE: The vent must have a 1/4 inch rise for each 1
foot of run towards the termination. NEVER allow
the vent to run downward. This will cause high tem-
peratures and may cause a fire.
NOTE: The location of the horizontal vent termina-
tion on an exterior wall must meet all local and na-
tional building codes. See page 8 of this manual for
proper terminal locations.

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
NOTE: IF installing termination on a siding covered
wall, a vinyl standoff or furring strips must be used to
ensure that the termination is not recessed into the
siding.
4. Before connecting the horizontal run of vent pipe to
the vent termination, slide the Wall Penetration Heat
Shield over the vent pipe (see figure 16, 18).
5. Slide the appliance and vent assembly towards the
wall, carefully inserting the vent pipe into the vent cap
assembly. The vent pipe must extend into the vent cap,
resulting in minimum pipe overlap of 1-1/4 inches.
Secure the connection between the vent pipe and the vent
cap by attaching the two sheet metal strips that extend
from the vent cap assembly into the outer wall of the vent
pipe. Use two sheet metal screws to connect the strips to
the pipe section (see figure 17).

VERTICAL TERMINATION
1. Maintain the 1” clearances to combustibles when
passing through ceilings, roofs, enclosures, attic rafters,
or other nearby combustible surfaces. Do not pack air
spaces with insulation. See the diagrams on page 11 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 chose to relocate the fireplace
or offset the venting to avoid cutting framing members
(see figures 19 and 20).

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 21 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 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”.
6. Continue to complete the assembly of the pipe lengths.
See figure 22 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.
See Offset Table on page 11 for additional offset details.

AERATION ADJUSTMENT
NOTE: The following assumes that the gas line has
been connected and leak tested by a qualified
technician.
The primary air adjustment is preset at the factory. Little
or no adjustment may be required for natural gas.
Propane will perform very differently at different
altitudes and from different fuel suppliers. Some
adjustment will most likely be needed for an appliance
burning propane.
The flame should have a blue base with yellow tips. A
dark orange flame with sooting and black smoke
indicates a lack of primary air. The primary air shutter is
located in the firebox under left hand side of the burner.
Adjust the primary mixture by loosening the set screw on
the air shutter and increasing the opening for more air
and a bluer / cleaner flame, or by closing the air shutter
for a more yellow flame. See figures 24 and 25 for proper
flame characteristics.

REMOTE CONTROL (Optional)
An Alpine Remote Control Kit (08501) may be installed
on this fireplace. The remote control kit comes with a
hand held transmitter, a receiver, a wall mounting plate,
The remote control is thermostatically controlled so you
can set the fireplace to the desired room temperature, and
have that temperature maintained. The remote control is
battery powered and will require periodic maintenance to
keep the system working properly.
1. Choose a convenient location on the wall to install the
receiver unit. A 22 Cu.In electrical box may be used. Run
wires from the fireplace valve to the desired wall
location. See the millivolt lead table on page 14 of this
manual for maximum wire runs.
2. Connect the wires to the gas valve (see figure 32).
3. Follow the installation instructions included with the
remote control kit.

WALL THERMOSTAT (Optional)
A wall thermostat may be installed if desired. Follow the
wire routing instructions on page 12 of this manual.
Alpine offers two types of wall mounted thermostats.
One is a basic heating type thermostat (part # 08260).
The other is a model (part # 08261). See your Alpine
dealer for additional information on the thermostats.
NOTE: If a Wall Thermostat is desired, there is no
need to install a wall junction box. The thermostat
wire will simply need to be routed to the desired
location of the wall thermostat and made accessible
through a small hole in the drywall. Both types of
thermostats are surface mounted on the finished wall.
They should not be installed until painting is
complete.
