NOTE: New appliances sometimes emit some smoke when first used due
to paint burning off the heating chamber. Do not mistake this smoke for an out-
of-adjustment appliance which will emit an acrid odor and cause sooting of flue
or vent. During initial running-in of the furnace, it is recommended that you
open windows to exhaust the smoke from the interior of the coach.

CAUTION
The Aqua-Hot's Exhaust is HOT!
DO NOT park in areas (i.e. dry, grassy fields) where dry conditions exist
underneath the vehicle, as a fire may result.
DO NOT operate the Aqua-Hot diesel burner inside an enclosed building.
OPERATING THE AQUA-HOT DIESEL BURNER OR ELEC-
TRIC HEATING ELEMENT WITHOUT THE 50/50 SOLUTION OF
WATER AND ANTIFREEZE WILL CAUSE SERIOUS DAMAGE TO
THE HEATER. BE SURE TO USE A GRAS/FDA APPROVED PROPY-
LENE GLYCOL BASED ANTIFREEZE SPECIFICALLY DESIGNED
FOR HYDRONIC HEATING SYSTEMS ONLY. FOR ADDITIONAL
INFORMATION PLEASE CALL 1.800.955.6226.
The heater should be shut OFF when refueling.
OPERATION
1. The diesel burner operates on 12 volt battery power. When dry-camping,
insure that the diesel burner is not operated with less than 12 volts battery
voltage
2. Check diesel fuel level.
3. Be certain the battery disconnect switch is in the ON position.
4. Activate the Aqua Hot switch on the face of kitchen cabinet. This switch
activates the diesel burner. (The Eng. Heat switch activates the engine pre-
heat and should be in the OFF position while engine is running. The 120
VAC switch controls the electric heating element in the system.)
5. Use Comfort Control wall thermostats to control temperature in individual
zones. There is an additional wall-mounted thermostat for the bathroom ex-
cept in 4200 Series coaches.
6. The Aqua-Hot burner should not emit smoke under normal operating con-
ditions. There will be smoke emitted during the first minute of warm-up.
If smoke is visible after full warm-up, check the following:
1. Low battery voltage
2. Fuel filter needs to be changed
3. Fuel nozzle may need to be changed
4. If coach fuel level is below 1/4 tank, Aqua-Hot fuel pick-up may be in-
gesting air.
