Installation
Installing The Gas Line
The gas line must be installed before finishing the
DV 52 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 5a
.
• 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

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.

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).
Vent Installation
This section covers the installation of direct venting and terminations.
Installation Requirements
•
DV 52 ST fireplaces are certified for use with European Home 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")
•
Flex vent sections over 6 feet must fall within the limits set by the venting graph and must
have a minimum vertical rise of 3 inches per foot of flex.
•
Solid vent sections may be cut less than half way from the female 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 Remote Switch
The
DV 52 ST
gas valve, located behind the lower horizontal panel, may be connected
to a wall switch. The valve generates its own power on
a millivolt circuit. Use only
low voltage wire, and DO NOT
connect any external power to it.
Note:
The switch location must not exceed 30' from the fireplace.

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 VSS Vinyl Shield when using on applications
with vinyl siding to guard against possible damage.
