Heating Operation With; Hermostat Odulating; Condensate Drain Trap Priming; Furnace Operation - Amana xMVM97 series Installation Instructions Manual

• If the differential is equal to or less than 2 degrees,
the furnace control board will follow the conventional
2-Stage algorithm, equivalent to a W1 request and
be reflected in the heat current demand status %.
• If the heat differential is greater than 2 degrees,
the furnace control board will follow the conventional
2-Stage algorithm, equivalent to a W2 request and
be reflected in the heat current demand status %.
• The circulator will operate per the heat airflow
profile.

HERMOSTAT
• When the Thermostat Heat Setup DIP switch is set
to 1-Stage heat, the furnace control board operation
will be compatible with a modulating communicating
thermostat (CTK02**, CTK03 or CTK04).
• When a call for heat is sent, the furnace will go
through the Light Off Sequence, at which time the
Heat Current Demand Status will still show 0%. After
the successful Light Off Sequence and expiration of
the Ignition Stabilization Period:
• The furnace control board adjusts to the low firing
rate.
• After 2 minutes, the furnace control board accepts
the specific Heat Requested Demand.
• If the differential is 2 degrees or less, the heat
current demand status will show 50%.
• If the specific heat requested demand is above 2
degrees, the heat current demand status will track
the specific heat requested demand.
• The circulator fan will operate per the heat airflow
profile.

ONDENSATE RAIN RAP
The drain trap MUST be primed prior to furnace startup. To
prime, fill the drain trap with water. This ensures proper furnace
drainage upon startup and eliminates the possibility of flue gases
escaping through the drain system. Please see requirements
in Condensate Drain Lines & Drain Trap section.
F O
URNACE PERATION
Purge gas lines of air prior to startup. Be sure not to purge lines
into an enclosed burner compartment. Follow NFPA 54, Na-
tional Fuel gas Code 8.3 for proper purging methods. In
Canada, follow approved purging methods in B149.1.
Check for leaks using an approved chloride-free soap and water
solution, an electronic combustible gas detector, or other ap-
proved method. Verify that all required kits (propane gas, etc.)
have been appropriately installed.

URNACE TARTUP
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 setting.
4. Remove the burner compartment door.

RIMING
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 4 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
temperature.
12. After the burners are lit, set the thermostat to desired
temperature.

URNACE HUTDOWN
1. Set the thermostat to the lowest setting.
The integrated control will close the gas valve and
extinguish 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.

OPERATING
Before placing a gas furnace or any gas appliance in opera-
tion, verify that the gas piping, gas fittings and all gas com-
ponents are safe and free of leaks by means of an electronic
combustible gas indicator and a gas meter dial test. Com-
bustible gas indicators must be calibrated and verified at
intervals prescribed by the instrument manufacturer.
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 proce-
