4.10 Gas Supply Pressure
Refer to the illustration
*
.
The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any
pressure testing of the system at test pressures in excess of 1/2 psi (3.5 kPa).
The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve
during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi (3.5 kPa).
Loosen the pressure port bolts before you check the gas inlet pressure.

Offset Adjustment.
Do Not Adjust without using a combustion analyzer
to verify adjustment. Adjust ONLY when in MIN
Fire and when using a combustion analyzer.

Once the CO2 and manifold pressure measurements for both MIN and MAX Fire are correct,
turn OFF the Control Display and set DIP switches 6 and 7 to the OFF position for
Nominal Fire (normal operation).
Turn the Control Display
back on when done.
20.
Write in the correct Conversion Date and the Technicians Name to the included gas
conversion sticker. See Figure F. Then apply that sticker adjacent to the rating plate.
21.
Put the boiler cover back on and assemble/tighten the 4 screws that hold the cover in place.
WARNING
Always make sure that the Control Display is turned
OFF before changing any DIP switch. Then turn Control
Display back ON to continue with CO2 measurements.
