Gas Supply Pressure Measurement - Amana MVM97 Installation Instructions Manual

Furnace Startup
1. Close the manual gas shutoff valve external to the
furnace.
2. Turn off the electrical power to the furnace.
3. Set the room thermostat to the lowest possible set-
ting.
4. Remove the burner compartment door.
NOTE: This furnace is equipped with an ignition device
which automatically lights the burner. Do not try to light
the burner by hand.
5. Move the furnace gas valve manual control to the OFF
position.
6. Wait five minutes then smell for gas. Be sure to check
near the floor as propane is heavier than air,
7. If you smell gas after five minutes, immediately
follow the Safety Considerations on page 3 of this
manual. If you do not smell gas after five minutes,
move the furnace gas valve manual control to the ON
position.
8. Replace the burner compartment door.
9. Open the manual gas shutoff valve external to the
furnace.
10. Turn on the electrical power to the furnace.
11. Adjust the thermostat to a setting above room tem-
perature.
12. After the burners are lit, set the thermostat to de-
sired temperature.
Furnace Shutdown
1. Set the thermostat to the lowest setting.
The integrated control will close the gas valve and ex-
tinguish flame. After the blower off delay expires, the
circulator blower de-energizes.
2. Remove the burner compartment door and move the
furnace gas valve manual control to the OFF position.
3. Close the manual gas shutoff valve external to the
furnace.
4. Replace the burner compartment door.

Gas Supply Pressure Measurement

T
O PREVENT UNRELIABLE OPERATION OR EQUIPMENT DAMAGE
INLET GAS SUPPLY PRESSURE MUST BE AS SPECIFIED ON THE UNIT
RATING PLATE WITH ALL OTHER HOUSEHOLD GAS FIRED APPLIANCES
.
OPERATING
Before placing a gas furnace or any gas appliance in
operation, verify that the gas piping, gas fittings and all
gas components are safe and free of leaks by means of an
electronic combustible gas indicator and a gas meter dial
test. Combustible gas indicators must be calibrated and
verified at intervals prescribed by the instrument manu-
facturer.
CAUTION
The line pressure supplied to the gas valve must be within
the range specified in the Inlet Gas Supply Pressure table.
The supply pressure can be measured at the gas valve
inlet pressure tap or at a hose fitting installed in the gas
piping drip leg. The supply pressure must be measured
with the burners operating. To measure the gas supply
pressure, use the following procedure:

1. Turn OFF gas to furnace at the manual gas shutoff
valve external to the furnace.
2. Connect a calibrated water manometer (or appropri-
ate gas pressure gauge) at either the gas valve inlet
pressure tap or the gas piping drip leg. See Honeywell
VR9205R gas valve figure for location of inlet pressure
tap.
