Junction Box Relocation; 24 Volt Thermostat Wiring - Amana MVM97 Installation Instructions Manual

Use a separate fused branch electrical circuit containing
properly sized wire, and fuse or circuit breaker. The fuse
or circuit breaker must be sized in accordance with the
maximum overcurrent protection specified on the unit
rating plate. An electrical disconnect must be provided at
the furnace location.
Connect hot, neutral, and ground wires as shown in the
wiring diagram located on the unit's blower door. For
direct vent applications, the cabinet opening to the
junction box must be sealed air tight using either an UL
approved bushing such as Heyco Liquid Tight or by apply-
ing non-reactive UL approved sealant to bushing.
Line polarity must be observed when making field con-
nections. Line voltage connections can be made through
either the right or left side panel. The furnace is shipped
configured for a right side (left side for counterflows)
electrical connection with the junction box located inside
the burner compartment. To make electrical connections
through the opposite side of the furnace, the junction
box must be relocated to the other side of the burner
compartment prior to making electrical connections. To
relocate the junction box, follow the steps shown below.
NOTE: Wire routing must not interfere with circulator
blower operation, filter removal, or routine maintenance.

To ensure proper unit grounding, an earth ground wire
must be connected between the furnace ground screw
located inside the furnace junction box and the electrical
service panel. NOTE: Do not use gas piping as an electri-
cal ground. To confirm proper unit grounding, turn off the
electrical power and perform the following check.
1. Measure resistance between the neutral (white) con-
nection and one of the burners.
2. Resistance should measure 10 ohms or less.
This furnace is equipped with a blower door interlock
switch which interrupts unit voltage when the blower
door is opened for servicing. Do not defeat this switch.
