Masport F39 Room Sealed Freestanding Gas Fire
PRESSURE TESTING
The manifold pressure is controlled by a regu-
lator 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" and/or "OUT" pressure
tap(s), turning counterclockwise with a 1/
8" wide flat screwdriver.
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. Read manometer.
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 (clockwise) with a 1/8"
flat screwdriver. Note: Screw should be
snug, but do not over tighten.
GAS CONNECTION
The gas connection is a 3/8" NPT 90
o
elbow.
The gas line can be rigid pipe or to make
installation easier, use a listed flexible connec-
tor and/or copper tubing if allowed by local
codes. Since some municipalities have addi-
tional local codes it is always best to consult
with your local authorities.
When using copper or flex connectors use
only approved fittings. Always provide a union
so that gas lines can be easily disconnected for
burner and/or valve servicing. Flare nuts for
copper lines and flex connectors are usually
considered to meet this requirement.
Important: Always check for gas leaks
with a soap and water solution or gas
leak detector. Do not use open flame for
leak testing.
Note: Prior to any pressure testing of
the gas supply piping system that
exceeds test pressures of 3.45
kPa, this appliance must be dis-
connected from the piping sys-
tem. If test pressures equal to or
less than 3.45 kPa are used then
this appliance must be isolated
from the piping system by closing
its individual manual shut-off valve
during the testing.
