PRESTIGE BOILER INSTRUCTIONS:
1. Turn power to the unit “OFF”.
2. Shut off the gas supply to the boiler at the main
manual shutoff valve.
3. Remove the front jacket panel.
4. Remove the air inlet elbow from the venturi.
5. Remove the Molex plug from the gas valve.
6. Disconnect the gas supply piping inside the
PRESTIGE at the brass union located just
before the gas valve.
7. Remove and save the two Torex screws attach-
ing the venturi / gas valve assembly from the
blower housing. See Fig.1. Remove the venturi
/ gas valve assembly from the blower housing.
Use the Torex wrench supplied in the kit to
remove screws.
There is a gasket between the venturi and blow-
er housing. If gasket “sticks” to the blower
housing use a flat blade putty knife to remove
any gasket material. Make sure not to scratch or
score the mating surface on the blower housing.
8. Remove the three screws attaching the gas
valve to the venturi. Use Torex wrench sup-
plied in kit to remove screws. Note orientation
of the venturi to the old gas valve for reassem-
bly of the venturi on the new gas valve.
9. Reassemble the new gas valve, gas valve/orifice
gasket and the three Torex screws from the kit
and reassemble the gas valve to the venturi. See
Fig. 2.
Ensure the gas valve/orifice gasket is in place
before reassembling the gas valve and venturi.
Failure to do so can result in death, serious
injury or substantial property damage.
