INSTALLATION OF GAS PRESSURE SWITCH
CAUTION: Check gas control valve pressure.
Pressure must not exceed 14” WC pressure.
1.
Remove pressure tap plug in gas valve.
(See Figure 3)
NOTE:
If installing on an existing
appliance, shut off gas supply to gas valve before
plug removal.
2.
Replace the pressure tap plug with the
1
⁄
8
” pipe
nipple and pipe tee. Install pressure tap plug at the
bottom of the pipe tee. (See Figure 4)
3.
Install the gas pressure switch into the side of the
pipe tee. The gas pressure switch is supplied with
a restrictor orifi ce in the inlet and outlet ports. With
these orifi ces in place, the switch does not need to
be vented. This feature complies with current ANSI
standards for gas regulators. (See Figure 5)
CAUTION: If for any reason the system has shut down
during operation, the cause of the system failure should
be investigated and corrected before resetting the
safety switch and restarting the system.
