To use waste engine heat for space and domestic water heating:
1. Install a switch, and/or an aquastat (part #1027), on the engine supply line to the heat
exchanger, and wire to the A-A terminals on the main control board.
2. Turn OFF, the ON/OFF control switch, located on the remote indicator panel. This will stop
the burner from operating, but all other heater functions will operate normally.
3. Start your engine.
4. When the engine aquastat heats up to its preset temperatures, it will automatically switch on
the circulating pump of the heating system. All other functions of the system will operate
normally.
5. The circulating pump will continue to operate until the engine aquastat has cooled down. A
manual switch can be wired in series with this aquastat to shut down the pump sooner if
required.
4-10.4 Domestic Water Operation
If your water heater is connected to the Hurricane heating system and its controlling aquastat (part
#1024) is wired to the W-W terminals on the main board, it will cycle the heater and the water pump.
A manual switch can be wired in series with this aquastat to shut down the operation if desired. A
bypass loop can be plumbed in for summer operation.
CAUTION: Where there is a chance of contamination of your domestic water when
using a heating system, use antifreeze specifically intended for hydronic heating systems.
Inhibited propylene glycol is recommended. Do not use automotive, ethylene glycol, or
any undiluted or petroleum based antifreeze as they can cause severe personal injury
should antifreeze leak into your potable water supply. Double wall heat exchangers are
available for potable water which will prevent contamination in the event of an internal
leak.
4-10.5 Troubleshooting
4-10.5.1 Overview
The electronic board consists of a flash micro controller programmed to monitor the timing and safety
function of the heater. Each time the board is energized by a call for heat, it will check its own circuits
for any problems. Should a problem exist, the board will shut down.
You can easily monitor your Hurricane heater’s operation by checking the electronic control box. Any
fault or problem will be immediately picked up by the control board and an LED diagnostic code
indicator will light up to pinpoint the fault. Once the fault has been corrected, it can be reset by
switching the service or remote switch OFF, then ON again. The diagnostic codes are described
below.
4-10.5.2 Power On (Green)
The POWER ON indicator is lit whenever the service switch on the control box is ON and if the
remote panel is switched ON, a small red LED near the lower right hand side of the digit on the
remote panel will also glow. If this light does not come on, check to see if the service switch is ON.
If the power on light does NOT come on:
Check for a blown fuse.
