Start-Up Preparation
Check For Gas Leaks
Prior to start-up and during initial oper-
ation, smell near the floor and around the
appliance for gas odorant or any unusual
odor. Do not proceed with the start-up if
there is any indication of a gas leak. Any
leaks found must be repaired immediate-
ly.
Propane installations only - The propane
supplier mixes an odorant with the
propane to make its presence detectable.
In some cases the odorant can fade and
the gas may no longer have an odor.
Prior to start-up of the appliance and
periodically after start-up have the
propane supplier check and verify the
odorant level.
Check Thermostat Circuit
- Disconnect the external thermostat wires
from the control terminal strip, located on
the drop down panel.
- Connect a voltmeter across the wire ends
of the external thermostat wiring.
- Energize each thermostat, zone valve and
relay in the external circuit, individually
and check the voltage reading across the
wire ends.
- There should NEVER be voltage mea-
sured at the wire ends.
- If voltage is measured at the panel under any
condition, check and correct the external
wiring.
In systems using 3-wire zone valves,
backfeed of voltage to the appliance is a
common problem. Use an isolation relay
to prevent voltage from the external cir-
cuit entering the CHALLENGER con-
trol panel.
- Reconnect the external thermostat
wires to the control terminal strip.
Inspection of Condensate Drain Assembly
1. Inspect and ensure the Condensate Drain
Assembly is properly installed as described
on page 28 and shown in Fig. 13 on page
29.
2. Remove the Condensate Drain Assembly
and fill with fresh water.
The condensate drain assembly must be
installed on the appliance and filled with
water when the CHALLENGER is in
operation. The condensate drain assem-
bly prevents flue gas emissions from
entering the condensate line. Failure to
ensure trap is filled with water could
result in severe personal injury or death.
3. Re-Install the condensate drain assembly.
