5.2 Detaching the Diesel-Burner Head
Instructions For Detaching the Diesel-Burner Head from the Aqua-Hot
CAUTION: Before detaching the Diesel-Burner Head, disconnect all
power supplies.
1. Loosen the two Eye-Bolt Nuts and swing the Eye-Bolts out of the way.
2. With both hands, carefully pull the Diesel-Burner away from the Aqua-
Hot, approximately 4-5 inches. Please note that you may have to lift the
head slightly while pulling it away from the Aqua-Hot.
3. Rotate the head approximately 90 angular degrees to the right or until all
the internal components are visible.
NOTE: It may be necessary to disconnect the two RED wires, which
are connected to pin #6 of the B-Zone relay, when rotating the head
beyond 90 degrees, see Figure 3.
CAUTION: When reattaching the Diesel-Burner Head to the Aqua-Hot,
be sure to properly align the head and DO NOT over tighten the Eye-Bolt
Nuts. An improper alignment and or an over tightening of the Eye-Bolt
Nuts can cause damage to the Diesel-Burner Head's aluminum-cast
housing (Blower Casing), see Figure 9.
