CHAPTER 10 - START-UP PREPARATION
10.5. Check For Gas Leaks
• Prior to start-up and during initial
operation, check for a gas leak using
a combustable gas detector. Do not
proceed with the start-up if there is any
indication of a gas leak. Any leaks found
must be repaired immediately.
• 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 unit and
periodically after start-up have the
propane supplier check and verify the
odorant level.
• Failure to comply with these instructions
can result in substantial property
damage, serious injury, or death.
10.6. Check Thermostat Circuit
• Disconnect the external thermostat wires from the
low voltage terminals.
• Connect a voltmeter across the wire ends of the ex-
ternal thermostat wiring.
• Close each thermostat, zone valve and relay in the
external circuit one zone at a time and check the
voltage reading across the wire ends.
• There should NEVER be voltage measured at the
wire ends.
• If voltage is measured under any condition, check
and correct the external wiring.
WARNING
In systems using 3-wire zone valves, voltage
backfeed to the unit is a common problem. Use
an isolation relay to prevent voltage from the
external circuit from entering the EXALT.
• Reconnect the external thermostat wires to the low
voltage terminal strip.
10.7. Inspect Condensate Drain Assembly
1. Inspect and ensure the Condensate Drain Assembly
is properly installed as described in Section 6.2 on
page 37.
2. Remove the plug from the Condensate Drain
Assembly and ll with fresh water.
The condensate drain assembly must be filled
with water when the EXALT is in operation.
The condensate drain assembly prevents flue
gas emissions from entering the condensate
line. Failure to ensure trap is filled with water
can result in serious injury, or death.
3. Re-Install plug in condensate drain assembly.
