INSTALLATION
VENTING
THE APPLIANCE MUST NOT BE CON-
NECTED TO A CHIMNEY FLUE SERV-
ING A SEPARATE SOLID FUEL BURN-
ING APPLIANCE.
This appliance is designed to be attached to two
3" (76mm) co-linear aluminium flex running the
full length of the chimney. The flue length must
be a minimum length of 8' (2.44m) and a maxi-
mum of 35' (10.7m). See chart for minimum
distances from roof. Periodically check that the
vent is unrestricted.
Masonry chimneys may take various contours
which the flexible liner will accommodate. How-
ever, keep the flexible liner as straight as
possible, avoid unnecessary bending.
HIGH ELEVATION
This unit is approved in Canada (CAN/CGA-
2.17-M91) for altitudes to 2000 ft. (610m) using
the factory -installed burner orifice. For instal-
lations from 2000 ft (610m) to 4500 ft (1370m)
the orifice sizes (DMS) for the Natural Gas and
Propane units must be changed. See the rating
plate for details. For installations above 4500 ft.
refer to current ANSI Z223.1 Sc8-8.1.2a ap-
pendix F or CAN/CGA-B149.1, for resizing
orifice.
GAS CONNECTION
The Emerald Insert is factory equipped to burn
Natural Gas, if necessary the unit can be
converted to burn Propane by using Conver-
sion Kit # 260-960. For minimum and maximum
supply pressure see the System Data table on
page 8.
Note: Prior to any pressure testing of
the gas supply piping system that
exceeds test pressures of 1/2
psig, this appliance and its individ-
ual shut-off valve must be discon-
nected from the piping system. If
test pressures equal to or less
than 1/2 psig are used then this
appliance must be isolated from
the piping system by closing its
individual manual shut-off valve
during the testing.
GAS CONNECTION WARNING:
Only persons licensed to work with gas piping
may make the necessary gas connections to
this appliance.
1) The gas inlet is located on the end of the
flexible pipe that emerges from the lower
left rear corner of the unit. The inlet fitting is
a 1/2" female flare.
A separate gas shut-off valve and a 1/8" IPS
plugged tapping should be installed immedi-
ately upstream of the connection to the
appliance.
2) The gas inlet is located on the end of the
flexible pipe that emerges from the lower
left rear corner of the unit. The inlet fitting is
a 1/2" female flare.
A separate gas shut-off valve and a 1/8" IPS
plugged tapping should be installed immedi-
ately upstream of the connection to the
appliance.
3) Locate the center point where the vent will
pass through the chimney above the appli-
ance. Move the appliance into the exact
location where it is to be installed. Ensure
that the Insert is level.
4) The gas control valve is provided with two
"IN" and "OUT" pressure taps, and are
easily accessible for a test gauge connec-
tion (see diagram on page 12).
5) Once the gas has been connected ensure
that the pilot valve is in line with burner.
CAUTION: If the door is removed or
opened for servicing, it must be replaced
and closed prior to operating the appli-
ance. The glass must be fixed in the door
when operating.
