Installation
Vent Installation
This section covers the installation of direct venting and terminations.
Installation Requirements
Vista 42 ST
Series fireplaces are certified for use with European Home Standard Series (5"
/ 8") venting components.
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 certified European Home vent components. (Use of other parts will void the
European Home warranty, and may impede the operation of the fireplace.)
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 flex pipe and
in any orientation (Male connectors can face in any direction)
.
Installing The Gas Line
The gas line must be installed before finishing the
Vista 42 ST
fireplace.
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 1/8" N.P.T. plugged
tapping and be accessible for test gauge connection immediately upstream of the
gas supply controls to the appliance. The fireplace 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 fitting, as required by
the
applicable installation codes
.
To access the fireplace gas connection the main burner must be removed as
shown below in Figure 5b.
• Only use gas shut-off 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-off valve must be disconnected from the gas

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.

supply piping system during any pressure testing of that system at test pressures in
excess of 1/2 psig (3.5 kPa).
The appliance must be isolated from the gas supply piping system by closing its
individual manual shut-off valve during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2 psig (3.5 kPa).

Cautions:
Vent terminations can be very hot. If the termination is less than 7 feet above a
public walkway, it should be fitted with a certified European Home Heat Guard.
(part no. PTKOG).
Do not obstruct, or attempt to conceal the vent termination. These actions
will affect the operation of the fireplace, and may be hazardous.
In heavy snow areas, take extra care to prevent snow buildup from obstructing
the vent termination.
Use European Home Vinyl Heat Shield (part no. VSS) when using on applica-
tions with vinyl siding to guard against possible damage.
Installing The Remote Switch
The
Vista 42 ST
are equipped with a remote-operated valve for use with a wall
switch. See Figure 21 for information on wiring the switch. The valve is pre-wired
and generates its own power.
DO NOT connect any external power to it.
Note:
The switch location must not exceed 30' from the fireplace.
