Prestige SOLO 60, 175 and 250 Boilers
Natural to Propane Instructions
3
The Solo 60 contains a natural gas orifice. This
orifice must be remove prior to the installation
of the propane orifice.
Failure to retain the rubber gasket on the gas
valve will cause an improper seal between the
gas valve and the venturi resulting in a potential
risk of a gas leak. Any potential gas leakage may
result in death, serious injury or substantial
property damage.
Ensure the proper orifice for propane as given in
Table 1. Failure to comply will affect input rate and
combustion of the boiler which may result in death,
serious injury or substantial property damage.
12. Reassemble the gas valve onto the venturi using
the three T-25 Torx head screws. Ensure the gas
valve is orientated with the venturi correctly.
13. With the venturi / blower gasket in place,
reassemble the venturi / gas valve assembly to
the blower housing using the two T-25 Torx
head screws.
For the reassembly process do not use adhesive
on the venturi / blower gasket.
Use care in the reassembly of the venturi / gas
valve to the blower housing not to cross thread
the mounting screws. Support the weight of the
venturi / gas valve assembly when threading the
mounting screws.
14. Reconnect the rectifier plug to the gas valve and
secure using the Phillips head screw (MCBA).
15. Reconnect Molex plug to the gas valve electri-
cal connection (TRIMAX).
16. Reconnect the brass gas piping union connec-
tion and open the manual gas shut off valve.
Before placing the Prestige boiler 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 bubble test. Failure to check for gas leaks
can cause severe personal injury, death or sub-
stantial property damage.
17. Reattach the air inlet elbow to the venturi.
18. Reposition the control panel and reattach the
retaining screw (MCBA).
19. Replace the front jacket panel and secure with
thumb screw.
20. Turn on the electrical power supply to the
Prestige boiler and return the unit back to service.
