U37 Regency ULTIMATE Rear Vent Direct Vent Freestanding Gas Heater 19
INSTALLATION
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 1/2 psig.
The manifold pressure is controlled by a reg-
ulator 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.

4) The latches should already be at the
proper setting. If they are too hard or too
easy to close, you may want to adjust
them by loosening the locking nut and
turning the latch catch. See diagram 3.
5) Remove the blue plastic protective coat-
ing from the glass.
6) Test the seal around the door by placing
a piece of paper between the unit and the
door, close the door and try to pull the
paper out. If it slips out easily, then the
door is not properly sealed. Tighten or
loosen the latch by turning the latch catch
inward or outward. See diagram 3.
Note: The door latch may require ad-
justment as the door gasket ma-
terial compresses after a few
fires and after glass replace-
ment. Turn the latch catch in-
ward or outward.

DOOR INSTALLATION
(Packaged Separately)
1) Open the two side panels.
2) Slide the door
onto the two
hinge pins mak-
ing sure the
two pieces are
flush together.
See diagram
1.
3) Close the door. The
latch plate must be
centered around the
alignment pin. See dia-
gram 2. If the latch plate
interferes with the cor-
ner of the stove you may
want to angle the plate
slightly so the door clos-
es easier.
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
