GAS PRESSURE CHECK
Check the inlet pressure to the burner to ensure that it is as shown in the table below.
NOTE: The pressure check point is located on the right side of the valve facing burner, for SIT
Millivolt, and the left side for SIT Modulating.
The appliance and its appliance main gas valve must be disconnected from the gas supply
piping system during any pressure testing of that system at test pressures in excess of 1/2 psi
(3.5kPa).
The appliance must be isolated from the gas supply piping system by closing its equipment shut
-off 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).

NOTE: On initial installation it may be necessary to bleed out air in the gas lines. Do this by
holding the control knob and turning the knob to the “PILOT” position for about 30 seconds.
To check the regulator pressure, remove the pressure tag plug at the left side of the regulator
facing the heater. The pressure should be checked with the heater burning and the control set
on high. After measuring the pressure, replace the pressure tap plug, ensuring that there are no
leaks.+
