8. Open the manual gas shut off valve. Before placing
the CHALLENGER back into operation check and
test all gas connections for leaks. Repair leaks if
found.
Do not check for gas leaks with an open flame. Use a bub-
ble test. Failure to check for gas leaks can cause severe
personal injury, death or substantial property damage.
Inspect Ignition Electrode
Inspection of the ignition electrode is not required on a
brand new previously unfired CHALLENGER unless after
completing the gas conversion, ignition issues are pre-
sent. Verify smooth ignition performance after complet-
ing the gas conversion to determine if the electrode may
require inspection.
Prior to inspecting the ignition electrode, ensure all electri-
cal power supply to the appliance is turned off to avoid elec-
trical shock.
1. Remove the ignition electrode using the T-15 Torx
wrench.
2. Remove any white oxides accumulated on the elec-
trode using fine grit sandpaper or steel wool. If the
electrode does not clean to a satisfactory condition,
replace the ignitor.
3. Check igniter to Fig. 2
4. When replacing the ignition electrode, ensure the
gasket is in good condition and correctly positioned,
replace gasket if necessary.
Check Inlet Gas Supply Pressure
1. Turn on the electrical power supply to the CHAL-
LENGER.
2. Check the inlet gas supply pressure to the CHAL-
LENGER at the gas valve see Figs. 3 & 4. Ensure a
minimum pressure of 5” w.c [13 mbar] during flow con-
ditions with all gas appliances firing including the
CHALLENGER and a maximum pressure of 13” w.c
[32 mbar] during non-flow conditions with all gas appli-
ances off including the CHALLENGER.
Combustion Test and Adjustments
1. The installer must perform a complete combustion
check to ensure the following combustion levels are
met at high and low input firing rates and the burner
is operating at optimum conditions for propane gas.
The combustion testing and adjustments must be performed
only by a qualified installer, service agency or the gas suppli-
er. All combustion measurements must be performed with
calibrated equipment to ensure proper readings and accura-
cy.
