Startup Procedure & Adjustment; Heat Anticipator Setting; Drain Trap Priming; Furnace Operation - Amana AMH95 Installation Instructions Manual

XIV. STARTUP PROCEDURE & ADJUSTMENT
Furnace must have a 115 VAC power supply properly connected
and grounded. Proper polarity must be maintained for correct op-
eration. In addition to the following start-up and adjustment items,
refer to further information in Section XVI, Operational Checks.
H A S
EAT NTICIPATOR ETTING
The heat anticipator in the room thermostat must be correctly ad-
justed to obtain the proper number of cycles per hour and to pre-
vent "overshooting" of the setting. Set the heat anticipator setting to
0.7 amps. Follow the thermostat manufacturer's instructions on
how to adjust the heat anticipator setting.
D T P
RAIN RAP RIMING
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 prohibits the possibility of flue gases escaping
through the drain system.
F
URNACE OPERATION
Purge gas lines of air prior to startup. Be sure not to purge lines
into an enclosed burner compartment.
Check for leaks using an approved chloride-free soap and water
solution, an electronic combustible gas detector, or other approved
method. Verify that all required kits (propane gas, high altitude,
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.
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 some types of gas are heavier than air.
7. If you smell gas after five minutes, immediately follow the
instructions 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.
F S
URNACE HUTDOWN
1. Set the thermostat to the lowest setting. The integrated
control will close the gas valve and extinguish flame.
Following a 15 second delay, the induced draft blower will
be de-energized. After a 100 or 150 second delay period
(field selectable), the circulator blower will be de-energized.
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.

HITE ODGERS
The line pressure supplied to the gas valve must be within the
range specified below. The supply pressure can be measured at
the gas valve inlet pressure boss 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 appropriate gas
pressure gauge) at either the gas valve inlet pressure boss
or the gas piping drip leg.
