About this Fireplace
The Vista 38 ST is a gas replace with a linear burner, available in black painted or
brushed stainless steel.
The Vista 38 ST is rated for 34,000 (maximum) BTU/Hr. (9.38) kilowatts input in natural gas
(NG), and 33,000 (maximum) BTU/Hr. (9.28) kilowatts input in liquid propane (LP).
CAUTION!
Due to its high operating temperatures, the appliance should be
located out of trac and away from furniture and draperies.
• Children and adults should be alerted to the hazards of the
high surface temperature, which could cause burns or clothing
ignition.
• Young children should be carefully supervised when they are in
the same room as the appliance.
• Clothing or other ammable materials should not be placed on
or near the appliance.
WARNING!
When this appliance is installed directly on carpeting, tile or any combustible
material other than wood ooring, it must be installed on a metal or wood
panel extending the full width and depth of the appliance.
What is Combustible?
Materials that can catch re and burn are considered combustible. Any material that
is made of, or faced with, wood, wood pulp, paper, plastic or any other material that
can catch re and burn is considered combustible. Even though these materials may
have been 'ame-proofed', made 're-resistant' or are 're-rated' they are considered
combustible.
The combustibility of a material can be tested per "ASTM E136 Standard Test Method
for Behavior of Materials in a Vertical Tube Furnace at 750 Degrees C". Note that 're-
resistant' does NOT mean non-combustible.
Note: If a certain material has a core considered to be non-combustible (in accordance
with ASTM E136) but is faced with a combustible material then the material is
considered to be combustible.
When in doubt, ask for an ASTM E136 compliance statement.
What is Non-combustible?
A given material is said to be non-combustible when it cannot catch re and burn.
For example, materials made entirely, or in combinations, of, stone, brick, concrete,
tile, steel, plaster or glass are considered non-combustible.
For the purposes of the installations described in this Manual, those materials that
have passed the ASTM E136 tests are considered to be non-combustible.
As of this writing, the materials listed below are reported by their manufacturers to
be non-combustible (in accordance with ASTM E136):
• James Hardie Building Products, Inc.:
HardieBacker™ ¼” Cement Board
• U.S. Architectural Products, Inc.:
Versaroc® Cement Bonded Particle Board
Cem-Clad® Cement Panel
• Vista 38 ST; uses a millivolt pilot ignition system.
• Vista 38 ST E; uses an electronic ignition system.

Installation
Installing the Fireplace Shell
The replace may be installed in any location that maintains proper clearances to air
conditioning ducts, electrical wiring and plumbing. Safety, as well as eciency of
operation, must be considered when selecting the replace location. Try to select a
location that does not interfere with room trac, has adequate ventilation, and oers
an accessible pathway for the venting installation. Refer to page 4 - Vent Installation
for more information.
The replace dimensions for Vista 38 ST models are shown below:
Top View
Front View
Side View
Figure 1. Fireplace dimensions.
Clearances
The clearances to combustible materials are:
* Clearance from the top of the replace to a combustible
ceiling within the replace enclosure.
** Refer to page 14.
L
Figure 2. Framing dimensions.
(Minimum 1" clearance must still be maintained around the vent pipes, except on
horizontal venting sections where the top of the pipe must have a clearance of 2")
For protection against freezing temperatures, it is recommended that outer walls of
the chase be insulated with a vapor barrier. This will reduce the possibility of a cold
air convection current on the replace.
Framing
1.) Frame the replace cavity (thru-wall design) according to Figure 2.
2.) Frame your installation, Figure 2a if the design incorporates a shelf over the
replace.
3.) Once complete, slide the replace into the completed cavity.
4.) Next, tack four jack studs (vertical, "broken line") in place, Figure 2c.
5.) Secure the replace in position by nailing/screwing the replace ange into
these jack studs.

Installation
Installing The Gas Line
The gas line must be installed before nishing the Vista 38 ST replace. Natural Gas
requires a minimum inlet gas supply pressure of 5.5" w.c. and a manifold pressure of
3.5" w.c. Propane Gas requires a minimum inlet gas supply pressure of 11" w.c. and
a manifold pressure of 10" w.c. Provision must also be made for a ⁄" N.P.T. plugged
tapping and be accessible for test gauge connection immediately upstream of the
gas supply controls to the appliance. The replace gas connection and the main
operating gas valve is located behind the removable trim at the bottom of the unit
and need only be attached to the gas line with an approved tting, as required by
the applicable installation codes.
• Only use gas shut-o valves approved for use by the state, province, region, or
governing body, in which the appliance is being installed, or as required by the
applicable installation codes.
• Flexible gas connectors must not exceed 3 feet in length, unless it is allowable within
applicable installation codes.
The appliance and its individual shut-o valve must be disconnected from the gas
supply piping system during any pressure testing of that system at test pressures in
excess of ½ psig (3.5 kPa).
Note: After the gas line is connected, each appliance connection, valve and
valve train must be checked while under normal operating pressure
with either a liquid solution, or leak detection device, to locate any
source of leak. Tighten any areas where bubbling appears or leak is
detected until bubbling stops completely or leak is no longer detected.
DO NOT use a ame of any kind to test for leaks.
The appliance must be isolated from the gas supply piping system by closing its
individual manual shut-o valve during any pressure testing of the gas supply piping
system at test pressures equal to or less than ½ psig (3.5 kPa).

Installing The Remote Switch
The Vista 38 ST gas valve, located behind the lower trim, is connected to a length
of thermostat wire and is switched by a remote controlled receiver. Strip the wire
insulation back ½" and connect the white and black wires to the receiver.
Note: The switch location must not exceed 30' from the replace.
Vent Installation
This section covers the installation of direct venting and terminations.
Installation Requirements
• Vista 38 ST Series replaces are certied for use with European Home Standard Series

• Minimum clearance to combustible construction around the vent pipe is 1" on all sides,
except on horizontal venting where the top of the pipe must have a clearance of at least
2".
• Use only certied European Home vent components. Use of other parts will void the
European Home warranty and may impede the operation of the replace.
• All joints must be secured with a minimum of two screws per joint.
• Vent terminations must not be recessed in walls or siding.
• Horizontal runs must be supported by a minimum of two supports per horizontal run. A
minimum of one screw on each side of support is also required.
• Flex vent sections may be stretched up to 50% of their total length (e.g. a 24" section may
be stretched to 36".)
• Venting components can be used in any combination of solid/rigid.
• Solid vent sections may be cut less than half way from the tapered end.
• Venting components can be used in any combination of solid/rigid pipe or ex pipe and
in any orientation, i.e. male connectors can face in any direction.

A 10' section of rigid pipe and a 90° elbow may be used in conjunction with a 3 ft.
ex section (PFL-3) will, when extended in a chase, allow for a maximum horizon-
tal run of 12'6" from the center of the replace to outside wall and a minimum of
7'6" when retracted in opposite direction. See Figure 22.
"D" ex sections and "E" solid sections may be used in conjunction with one an-
other to obtain dierent possible horizontal length installations. NOTE: Flex section
must not exceed maximum horizontal length of 3 feet and for this application the
top clearance is to the ceiling.

Vertical Vent Installations
• Maximum vent height is 30 feet above replace.
Note: Flame characteristics will change if the maximum vent height is used.
• Minimum clearance to combustible construction around the vent pipe is
1" on all sides must be maintained, except on horizontal venting where the
top of the pipe must have a clearance of at least 2".

2. Oset Vertical Installations
• A maximum of two osets (each oset has two 90° bends) may be made if
the length of the osets does not exceed 25% of the vertical vent height, when
measured center to center of piping.
Using this vent installation example:
• 30' vertical vent
• 2 - 2' osets required
Maximum oset allowed = 25% of 30'or 7½'.
This venting conguration meets requirements.
Heat Shields
Due to high ue temperatures, the heat shield (RHS101) must be used on all in-
stallations straight through the wall, at the point where the vent pipe connects
to the termination. With the heat shield, vent clearances can be maintained at 1".
The heat shield is not included with the replace.
To install the heat shield, slide one section over the vent pipe on the inside of the
wall opening, with the circular portion inside the wall cavity. Screw the shield in
place over the wall opening. Install the second section on the outside of the wall
opening sliding the circular portion into the wall opening. Refer to Figure 21.

Reduced Vertical Installation
(Available with Linear LDVPV47 Power Vent ONLY)
It is possible to reduce vertical vent runs from 5"/8" venting to 4"/7" venting.
Reduced vertical venting may only be used when the linear power vent is required.
This is commonly due to longer than normal vent runs or unusually long horizontal
vent runs.

The Horizontal and
Vertical Power Vent
A power vent is required where the Termination is located too far away from the
gas replace and/or if the vent run is beyond the scope of this document, or the
specications recommend vent augmentation. There are four 5"/8" power vent
models available. These power vents oer superior venting, safe operation and years
of trouble free operation.
The available European Home Power Vent models are:
LDVPV47/58 - linear, interior in-line power vent
EDVPV47/58 - external power vent module
EDVRSPV47/58 - exterior vertical roof mount stainless steel power vent system
EDVWSPV47/58 - exterior horizontal wall mount stainless steel power vent system

Finishing Around the Fireplace
Combustible mantels and moldings may be safely installed over the top and on the
front of the replace provided that they do not project beyond shaded area shown
in Figure 27. Side wall clearances are 0". Combustible surrounds may be installed
with 0" clearance to the side of the replace as shown in Figure 27.
Fireplace Facing
When selecting the nish material for your replace, it is important to remember
the following: THE OPENING MUST NOT BE OBSTRUCTED IN ANY WAY - to do so
restricts the air supply for the control compartments and heat exchanger. It
also prevents access for servicing controls.
The face of the replace may be painted to match the room decor provided you use
a heat-resistant paint. Decorative facing must not extend past the replace open-
ing at all, because it will interfere with the access to retainers for removal of glass
door. When using a tile facing, you must NOT tile over the outside frame of the
replace, as this will obstruct the door removal. See Figure 27.
Mantels and Surrounds
NOTE: Mantel clearances are for the prevention of re hazards.
New technology, to meet consumer and government demands for the wise use of
energy, has prompted us to manufacture many models of replaces which are hot,
fuel and energy ecient.
Please be aware; temperatures over the mantel will rise above normal room
temperature and walls above replace may be hot to touch.
We recommend careful consideration be given to the eects of elevated mantel
temperatures which may be in excess of product design, for example: candles,
plastic or pictures. This can cause melting, deformation, discoloration or premature
failure of T.V. and radio components.

General
• Have the replace and installation inspected yearly. The inspection must
include, but is not limited to, the following:
• A visual check of the entire vent system and termination.
• An inspection of the explosion relief appers and the door gasketing to
ensure a proper seal.
• An inspection of the burner, venturi, and primary air openings.
• An inspection of the gas valve, gas components, and pilot ame. For your
convenience a ⁄" manifold pressure tap is supplied on the gas valve for a
test gauge connection. See Figure 44.
• Ensure proper media placement as per this manual.
• Inspection of all optional equipment; fans, thermostats, etc.
• For natural gas this appliance requires a minimum inlet pressure of 5.5" w.c. and
a manifold pressure of 3.5" w.c.
• For propane (L.P.) gas this appliance requires a minimum inlet pressure of 11"
w.c. and a manifold pressure of 10" w.c.
• Always keep the replace area clear and free of combustible materials, as well as
gasoline and other ammable vapors and liquids.
• Do not use this appliance if any part has been under water. Immediately call a
qualied service technician to inspect the appliance and to replace any part of
the control system and any gas control which has been under water.
Cleaning
When the replace is rst activated, there may be some smoking and a visible lm
may be left on the glass. This is a normal condition, and is the result of burning of
protective coatings on new metal.
• Glass must be cleaned periodically to remove any lm (which is a normal by-product
of combustion) which may be visible. Film can easily be removed by removing
the door, as shown on page 16. Handle the door carefully, and clean it with
non-abrasive glass cleaners.
• Silicone seals on inner door during initial ring will "o gas", leaving a visual
deposit of a white substance on combustion chamber walls. This can easily be
removed using normal household products.
• Use a vacuum cleaner or whisk broom to keep the control compartment, burner,
and rebox free from dust and lint.
• Stones may be cleaned periodically with a vacuum to remove soot or other
contaminates.
Burner Adjustment
The Vista 38 ST is equipped with an adjustable burner, allowing you to raise or
lower the ames. To adjust the ames, locate the black knob marked 'Hi-Lo', in the
center of the gas control valve See Figure 42. The front burners are not adjustable.
• To raise the ame height, turn the black knob (located behind the lower trim)
counterclockwise.
• To lower the ame height, turn clockwise.
