7.1.7
Check gas supply line routing
Openings for the gas supply line are provided at the back and left side
of the appliance case (see figure 2). The appliance is supplied with a
plate covering the back opening. The opening at the left side is
uncovered as supplied. If the supply line is to enter through the back,
remove the plate and refit to the side opening.
7.1.8
Fit case levelling screws if necessary.
Place the appliance in position in the fireplace opening and check
for stability. If necessary fit a levelling screw and lock nut into the
threaded holes neasr the rear corners of the case. Adjust the screws
to level the appliance
7.2. Install to fireplace
7.2.1
Secure the collar on the vent connector unit to the 3" diameter
chimney liner (Fig. 8).
7.2.2
Slide the fire unit into the fireplace making sure that the vent
connection unit is above the appliance case. Leave the case
front a few inches clear of the fireplace front to allow you to
fix the vent connector to the top of the case.
7.2.3
Pull the vent connector towards the front of the fireplace and
locate the rear slot in the plate on the lip at top rear of the
appliance case. Fix the front of the vent connector plate to the
appliance case top using the screw previously removed (Fig.8).
7.2.4
Push the appliance fully home against the front face of the
fireplace. Make sure that no sags or dips occur in the liner.
7.3. Installation of gas supply
7.3.1
For access to the connection elbow, detach the log support
tray by removing two screws then detach the access cover
plate by removing two screws – See fig. 9.
7.3.2
Use only new black iron or steel pipes or copper tubing if
acceptable. Check local codes. Note: In USA copper tubing
must be internally tinned for protection against sulfur
compounds. Unions in gas lines should be of ground joint
type.
The gas supply line must be sized and installed to provide a
supply of gas sufficient to meet the maximum demand of the
appliance without undue loss of pressure. Sealants used for
natural gas models as well as propane versions must be
resistant to the action of all gas constituents including L.P. gas.
Sealants should be applied lightly to male threads to ensure
excess sealant does not enter gas lines.
The supply line should include a manual shut-off valve and union in the line to allow the appliance to be disconnected for
servicing.
A plugged 1/8" NPT tapping must be installed in the line. The tapping must be accessible for test gauge connection and be
immediately upstream of the gas supply connection to the appliance.
All piping and connections must be tested for leaks after installation or servicing. All leaks must be corrected immediately.
When testing for leaks:-
a.
Make sure that the appliance control knob is at the OFF position.
b.
Open the manual shut-off valve.
c.
Test for leaks by applying a liquid detergent or soap solution to all joints. Bubbles forming indicate a gas leak.
NEVER USE AN OPEN FLAME TO CHECK FOR LEAKS.
d.
Correct any leak detected immediately.
7.3.3
Refit the access cover plate and log support tray after connecting the gas supply.
