Natural to Propane Instructions

Failure to retain both rubber o-rings on the
brass union collar will cause an improper seal
between the piping and gas valve resulting in a
potential risk of a gas leak. Any potential gas
leakage can result in substantial property dam-
age, serious injury, or death.
Ensure the proper orifice for the model is installed
per Table 1 on page 2. 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 brass union collar onto the gas
valve using the four (4) T-25 Torx head screws.
Ensure the o-rings are properly placed and in
good condition.
11. Place the gas valve between the brass union and
the gas supply piping. Retighten the union just
above the gas valve and install the four (4) T-25
Torx head screws to attach the gas supply pip-
ing to the gas valve.
12. Reconnect the gas valve electrical connections
as shown in Fig. 3.
13. 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.
