Circulator Blower Fan Timing Adjustment; Operational Checks; Burner Flame; Auxiliary Limit Control - Amana AMH8 Installation Instructions Manual

1. Turn OFF power to the furnace.
2. Select the heating and cooling blower speeds that match
the installation requirements from the airflow table in the
Product Data Book applicable to your model.(Please
contact your distributor or our website for the applicable
product data book referred to in this manual.)
3. Relocate desired motor leads to the circulator blower heat
and cool speed terminals on the integrated control module.
(Terminals are identified as LO HEAT, HI HEAT and COOL
(hot)). If a heating speed and the cooling speed are the
same, a jumper wire must be used between the heat and
cool terminals.
4. Connect all unused blower motor leads to the "PARK"
terminals on the integrated control module. Any leads not
connected to the "PARK" terminals must be taped.
5. Turn ON power to furnace.
6. Verify proper temperature rise as outlined in Temperature
Rise section.

NOTE: Items in this section refer to the air circulator blower fan,
NOT to the induced draft blower. The induced draft blower timing
sequence is not adjustable. The circulator blower fan timing is
adjustable only on models with optional "heating fan OFF delay"
adjustment pins or switches. It is NOT adjustable in any other
circumstances.
As shipped, the circulator blower fan will remain on for 150
seconds after the gas valve closes. When a call for cooling occurs,
the circulator fan comes on and remains on for 45 seconds after
the call for cooling ends. During normal heating operation, the
circulator fan will come on approximately 34 seconds after the
gas valve opens.

The burner flames should be inspected with the burner
compartment door installed. Flames should be stable, quiet,
soft, and blue (dust may cause orange tips but they must not be
yellow). Flames should extend directly outward from the burners
without curling, floating, or lifting off. Flames must not impinge on
the sides of the heat exchanger firing tubes.

UXILIARY IMIT ONTROL
Auto reset limits are located on or near the blower. To access this
auxiliary limit, disconnect the electrical power and remove the
blower door. The auxiliary limit control is designed to prevent
furnace operation in case of main blower failure on horizontal
installations. It may also open if the power supply is interrupted
while the furnace is firing. The auxiliary limit control is suitable for
both horizontal right and horizontal left installations. Regardless
of airflow direction, it does not need to be relocated.
