Gas Pressure Setting Procedure
CONTINUUM and INTEGRITY
REU-2532- W
All settings/adjustments must be performed
by a qualified Service Technician.
1. Turn unit off at power source and turn off the gas to the water heater.
2. Remove the front cover from the water heater.
3. Remove the gas pressure test port plug. Connect manometer to this port. See Figure #1 for location of the
test port plug. Turn on the gas to the water heater.
4. Flow water through the water heater at the maximum flow rate obtainable, at least three gallons per minute.
5. To adjust the “Low” fire pressure, set combustion control dip switch #7 to the “ON” position, and switch
#8 to the “OFF” position (see figure #2 for location of combustion control switches.) This will put the unit
into forced low fire. Check the pressure reading on your manometer. If the pressure needs adjusting, remove
the rubber plug from the bottom of the water heater casing (located beneath the regulator), to access the
regulator adjustment screw. Adjust the regulator screw to achieve the correct gas pressure. (See figure #1 for
location of the regulator adjustment screw.) Below are the proper pressures for “Low” fire, per gas type.
Propane 0.88” w.c
. @ 10” w.c. supply (Low fire rate of 15,000 BTU’s)
Natural 0.56” w.c
. @ 6” w.c. supply (Low fire rate of 15,000 BTU’s)
6. To adjust the “High” fire pressure, set combustion control dip switch #7 to the “ON” position, and switch
#8 to the “ON” position (see figure #2 for location of the combustion control switches), this will put the unit
into forced high fire. Check the pressure reading on your manometer. If the pressure needs adjusting,
adjust it by turning the high pressure “Pot”. See figure #2 for location of “high pressure setting pot”.
Below are the proper pressures for “High” fire.
Propane 5.1” w.c
. @ 10” w.c. supply (High fire rate of 180,000 BTU’s)
Natural 3.4” w.c
. @ 6” w.c. supply (High fire rate of 180,000 BTU’s)
7. Verify both low and high fire pressures by placing the water heater into “Forced Low Fire” and “Forced
High Fire” as described in steps 5 and 6 above. This completes the gas pressure setting procedure.
Dip switches #7 and #8 (combustion control switches), MUST be returned to the “Off” position, after
setting the pressures.
