Prestige SOLO 155/175/250 - ACVMax Boilers
Natural to Propane Instructions
3
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 can
result in substantial property damage, serious
injury, or death.
Ensure the proper orifice for the model is installed
per Table 1. Failure to comply will affect input rate
and combustion of the boiler which can result in
substantial property damage, serious injury, or
death.
10. 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.
11. 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.
12. Reconnect Molex plug to the gas valve electri-
cal connection.
13. 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 result in substantial property damage, seri-
ous injury, or death.
14. Reattach the air inlet elbow to the venturi.
15. Replace the front jacket panel and secure with
screws.
16. Turn on the electrical power supply to the
Prestige boiler and return the unit back to service.
