Ropane As Anks And Iping - Amana AMV9 Installation Instructions Manual

•
Connect the furnace to the building piping by one of the
following methods:
–
Rigid metallic pipe and fittings.
–
Semi-rigid metallic tubing and metallic fittings.
Aluminum alloy tubing must not be used in exterior
locations. In order to seal the grommet cabinet
penetration, rigid pipe must be used to reach the outside
of the cabinet. A semi-rigid connector to the gas piping
may be used from there.
•
Use listed gas appliance connectors in accordance with their
instructions. Connectors must be fully in the same room as
the furnace.
•
Protect connectors and semirigid tubing against physical and
thermal damage when installed. Ensure aluminum-alloy tubing
and connectors are coated to protect against external
corrosion when in contact with masonry, plaster, or insulation,
or subjected to repeated wetting by liquids such as water
(except rain water), detergents, or sewage.

IRECT TANDARD NLET IPING
When gas piping enters directly to the gas valve through the stan-
dard inlet hole, the installer must supply straight pipe with a ground
joint union to reach the exterior of the furnace. The rigid pipe must
be long enough to reach the outside of the cabinet to seal the grom-
met cabinet penetration. A semi-rigid connector to the gas piping
can be used outside the cabinet per local codes.

NDIRECT LTERNATE
When gas piping enters indirectly to the gas valve through the alter-
nate gas inlet hole the following fittings (starting from the gas valve)
to reach the outside of the cabinet must be supplied:
•
Coupling.
•
90 degree elbow.
•
2 inch close nipple.
•
90 degree elbow.
•
Straight pipe, with a ground joint union, to reach the exterior
of the furnace. The rigid pipe must be long enough to reach
the outside of the cabinet so as to seal the grommet cabinet
penetration. A semi-rigid connector to the gas piping can be
used outside the cabinet per local codes.

Before placing unit in operation, leak test the unit and gas connec-
tions.

pressure may damage the gas valve and cause subsequent
overfiring, resulting in heat exchanger failure.
Disconnect this unit and shutoff valve from the gas supply piping
system before pressure testing the supply piping system with pres-
sures in excess of 1/2 psig (3.48 kPa).
Isolate this unit from the gas supply piping system by closing its
external manual gas shutoff valve before pressure testing supply
piping system with test pressures equal to or less than 1/2 psig (3.48
kPa).

ROPANE AS ANKS AND
P
ROPANE GAS IS HEAVIER THAN AIR AND ANY LEAKING GAS CAN SETTLE IN
ANY LOW AREAS OR CONFINED SPACES.
PERSONAL INJURY, OR DEATH DUE TO FIRE OR EXPLOSION CAUSED BY A
PROPANE GAS LEAK, INSTALL A GAS DETECTION WARNING DEVICE.
A gas detecting warning system is the only reliable way to detect a
propane gas leak. Rust can reduce the level of odorant in propane
gas. Do not rely on your sense of smell. Contact a local propane
gas supplier about installing a gas detecting warning system. If the
presence of gas is suspected, follow the instructions on Page 4 of
this manual.
All propane gas equipment must conform to the safety standards of
the National Board of Fire Underwriters, NBFU Manual 58.
For satisfactory operation, propane gas pressure must be 11 inch
w.c. at the furnace manifold with all gas appliances in operation.
Maintaining proper gas pressure depends on three main factors:
1. Vaporization rate, depending on temperature of the liquid,
and "wetted surface" area of the container or containers.
2. Proper pressure regulation. (Two-stage regulation is
recommended for both cost and efficiency).
