Check Inlet Gas Supply Pressure; Operating At High Altitudes - RBI Infinite Energy2 IW199 Installation And Operation Instructions Manual

13 - INSTALLATION - Gas supply
13.4 - Check
inlet gas supply
pressure
WARNING!!!
DO NOT
adjust or attempt to measure
gas valve outlet pressure. The
gas valve is factory-set for the
correct outlet pressure. This
setting is suitable for natural
gas and propane, requiring no
field adjustment. Attempting to
alter or measure the gas valve
outlet pressure could result in
damage to the valve, causing
excessive levels of carbon
monoxide, which can result
in severe personal injury or
death!
NOTICE! The maximum inlet gas
pressure must not exceed the value
specified by the manufacturer and that
the minimum value listed is for the
purposes of input adjustment.
The gas piping must be sized for the
proper flow and length of pipe, to
avoid excessive pressure drop. Both
the gas meter and the gas regulator
must be properly sized for the total
gas load.
If you experience a pressure drop
greater than 1"W.C., the meter,
regulator, or gas line is undersized or
in need of service.
1.- Follow Section 14.7 to check the
inlet gas supply pressure;
2.- If gas supply pressure is within
normal range and no adjustments
are needed, proceed on to step 4;
3.- If the gas pressure is out of range,
contact the gas utility, gas supplier,
qualified installer or service agency
to determine the necessary steps to
provide proper gas pressure to the
appliance;
4.- Turn the power switch to the "OFF"
position;
5.- Shut off the manual gas shut off
valve;
6.- After verifying the correct
gas pressures disconnect the
manometer, turn the screw in
pressure connection "D" in Figure
13-6, clockwise until snug and
check for any gas leaks.

CAUTION!!!
Never force the
pressure connection screw or
the gas valve will be damaged!
WARNING!!!
Never use an
open flame to check for gas
leaks, or a fire or an explosion
could result causing severe
personal injury or death!
13.5 - Operating at
high altitudes
For installations in the United
States:
the appliance is rated for operation at
altitudes up to 10,000 ft (3078 m).
For altitude above 2,000 ft (610
m) check and adjust the CO2 level
following Section 14.8. This will result
in an authomatic input downrate of 3%
each 1,000 ft (305 m) altitude.
For installation in Canada:
the appliance is rated for operation at
altitudes up to 4,500 ft (1372 m).
For altitude above 2,000 ft (610
m) check and adjust the CO2 level
following Section 14.8. This will result
in an authomatic input downrate of 3%
each 1,000 ft (305 m) altitude.
