Vista 38 ST See-thru Gas Fireplace

Installation
Installing The Gas Line
The gas line must be installed before finishing the
Vista 38 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
.
• 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
supply piping system during any pressure testing of that system at test pressures in
excess of 1/2 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 flame of any kind to test for leaks.
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).

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 1/2" and connect the white and black wires to the receiver.
Note:
The switch location must not exceed 30' from the fireplace.
Vent Installation
This section covers the installation of direct venting and terminations.
Installation Requirements
•
Vista 38 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, i.e. male connectors can face in any direction.
