Prestige Solo Installation and Maintenance Manual

Start-Up Preparation
- Remove the front jacket panel and check for
continuity across the low water cut-off device
wire terminals. The contacts should be closed
when system pressure is greater than 10 psi.
See item 6, on Fig. 36 page 78(PRESTIGE
Solo 60) or on Fig. 37 page 79 (PRESTIGE
Solo 175/250) or Fig. 38 page 80 (PRESTIGE
Solo 399) for location of the LWCO.
Check For Gas Leaks
Prior 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 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 periodi-
cally after start-up have the propane sup-
plier check and verify the odorant level.
Check Thermostat Circuit
- Disconnect the external thermostat wires
from the low voltage terminal strip.
- 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 wiring.
In systems using 3-wire zone valves, back-
feed of voltage to the unit is a common
problem. Use an isolation relay to prevent
voltage from the external circuit entering
the PRESTIGE Solo control panel.
- Reconnect the external thermostat
wires to the low voltage terminal strip.
Inspection of Condensate Drain Assembly
1. Inspect and ensure the Condensate Drain
Assembly is properly installed as described
on page 24 and shown in Fig. 14 on page 25.
2. Remove the plug from the Condensate
Drain Assembly and fill with fresh water.
The condensate drain assembly must be
filled with water when the PRESTIGE
Solo is in operation. The condensate
drain assembly prevents flue gas emis-
sions from 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.
