GAS LINE CONNECTION
10.1
Open the control panel door.
10.2
Pull off the two control knobs.
10.3
Detach the control cover panel (see figure 9):-
•
Remove three screws.
•
Lift the panel up
•
Pull the bottom front corner of the panel forward and
out to clear the case and then lift clear.
10.4
Couple the gas inlet pipe to the connector below the
regulator (see figure 10).
10.5
Connect the other end of the inlet pipe to the elbow
attached to the supply line.
11.
SYSTEM CHECK
11.1
Pressure test the supply line for leaks.
•
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 ½psig (3.5kPa).
•
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
½psig (3.5kPa).
•
Failure to either disconnect or isolate the appliance
during pressure testing may result in regulator or valve
damage. Consult your dealer in this case.
11.2
The appliance is preset to give the correct input with
natural gas. For input adjustment, the gas supply pressure
to the appliance inlet must within the range shown in
section 2 of this manual.
11.3
The burner manifold pressure is controlled by a built-in
non-adjustable regulator. The correct pressure range is
shown in the table in section 2 of this manual. The
manifold pressure should be checked at the pressure test
point which is located on the thermostat unit (see figure
10). The pressure check should be made with the
appliance burning, the gas control set at “On” and the
thermostat control set at “Full”. (Temporarily refit the
control knobs for checking.)
11.4
All piping and connections must be tested for leaks after
installation or servicing. All leaks must be corrected
immediately.
When testing for leaks:
•
Make sure that the appliance gas control knob is at the
“Off” position.
•
Open the manual shut-off valve.
•
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.
•
Correct any leak detected immediately.
