Masport F38-1 Freestanding Gas Heater

INSTALLATION
as long as an approved inner flue is installed.
Fasten but do not penetrate the inner sleeve of
the flue when tightening the screw.
The minimum flue required is 3.3m from floor
level.
Follow all flueing manufacturer’s requirements
and local building codes or AG 601.
GAS CONNECTION
The gas line should be rigid pipe. Copper may
also be used if approved by AG 601.
The gas connection at the valve is 1/2 male. 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). Disconnect piping from valve at pres-
sures over 3.45 kPa (14" w.c.).
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" (# 7) and/or "OUT" (# 6)
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.
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. Screw should be snug,
but do not over tighten.
