Start-Up Preparation

Check For Gas Leaks

WARNING
P r i o r to start-up and during initial opera-
tion, smell near the floor and around the
unit 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 re p a i red immediately.
WARNING
Propane installations only - The propane
s u p p l i e r 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 periodi-
cally after start-up have the propane
supplier check and verify the odorant
level.

Check Thermostat Circuit

- Disconnect the external thermostat wires
from the 24V terminal strip on the wiring
panel.
- Connect a voltmeter across the wire ends of
the external 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 at the panel under any
condition, check and correct the external
w i r i n g .
NOTICE
In systems using 3-wire zone valves,
backfeed of voltage to the unit is a com-
mon problem. Use an isolation relay to
prevent voltage from the external circuit
entering the PRESTIGE control panel.
- Reconnect the external thermostat
wires to the 24V terminal strip on the
wiring panel.

Inspection of Condensate System

1. Inspect and ensure the condensate drain
system is properly installed as described on
page 24 and shown in Fig. 14 on page 25.
2. Remove the plug from the Condensate Trap
assembly and fill the trap with fresh water.
NOTICE
The condensate trap assembly must be
filled with water when the PRESTIGE is
in operation.
assembly prevents flue gas emissions
f rom entering the condensate line.
Failure to ensure trap is filled with water
could result in severe personal injury or
death.
3. Re-Install plug in condensate drain assem-
bly.
