INSTALLATION
GAS CONNECTION
The gas line can be rigid pipe, or to make installation easier,
use a listed flexible connector if allowed by local codes.
Copper may also be used if approved by local codes.
The gas connection at the valve is 1/2 inch BSP. For minimum
and maximum supply pressure see the System Data Table.
GAS PIPE PRESSURE TESTING
The appliance must be isolated from the gas supply piping
system by closing its individual manual shut-off valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig. (3.45 kpa). Discon-
nect piping from valve at pressures over 1/2 psig (3.45 kPa).
The manifold pressure is controlled by a regulator built into
the gas control, and should be checked at the pressure test
point.
Note: To properly check gas pressure, both inlet and
manifold pressures should be checked using the
valve pressure ports on the valve.
1)
Make sure the valve is in the "OFF" position.
2)
Loosen the "IN" (# 7) and/or "OUT" (# 6) pressure tap(s),
turning counterclockwise with a 1/8" wide flat screwdriv-
er.
3)
Attach manometer to "IN" and/or "OUT" pressure tap(s)
using a 5/16" ID hose.
4)
Light the pilot and turn the valve to "ON" position.
5)
The pressure check should be carried out with the unit
burning and the setting should be within the limits
specified on the safety label.
6)
When finished reading manometer, turn off the gas
valve, disconnect the hose and tighten the screw (clock-
wise) with a 1/8" flat screwdriver.
Screw should be snug,
but do not over tighten.
