GAS PRESSURE CHECK
Check inlet pressure to burner to ensure that it is as shown in table below.
NOTE: The pressure check point is located on right side of valve facing burner, for ITT, and
left side for SIT.
The appliance and its appliance main gas valve must be disconnected from 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 gas supply piping system by closing its equipment shut-off
valve during any pressure testing of 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 gas lines. Do this by
holding control knob and turning knob to “PILOT” position for about 30 seconds.
To check regulator pressure, remove pressure tag plug at left side of regulator facing heater.
The pressure should be checked with heater burning and control set on high. After measuring
pressure, replace pressure tap plug, ensuring that there are no leaks.
* For the purpose of minimum input adjustment.
