11- 2 Installation Manual for Hurricane® Zephyr™ HW Heating System
We recommend that you add a mixture of 50% water and 50%
antifreeze. NEVER use more than a 50/50 mixture, since the
added viscosity of the antifreeze solution will cause circulation
problems. Your antifreeze/water mixture should be changed
every three years. Antifreeze does wear out and can become
very acidic.
A coolant conditioner can be added to the water system, to keep
the coolant alkaline and not acidic, see page 3-14. These
inhibitors also prevent the coolant from forming calcium scales.
Conditioners are available from diesel engine manufacturers to
maintain water stability and prolong heater life. If a conditioner is
not installed in your system, check the pH level yearly. The
components inside the heater should not normally require
maintenance, except for periodic checks for obvious problems,
such as leaks or overheating.
11.3 Nozzle
Nozzle problems such as clogging will result in a poor flame,
small and blue. Carefully disassemble. Hold nozzle vertically and
turn stem counter clockwise. Clean distributor orifice and air slots
of any debris using solvent and high-pressure air. Check O-rings
for nicks and replace if in doubt. A leaking O-ring will allow air
into the fuel causing popping of the flame.
11.4 Fuel Lines and Filter
You should check your filter every season to determine if it needs
replacement. The frequency depends largely on the quality of
fuel you’ve been using.
11.5 Combustion Chamber
The quality of the fuel varies and some ash is left in the chamber
after combustion. The burner and combustion tube must be
removed and the combustion chamber vacuumed clean every
1000 hours. If this is neglected, the exhaust will be restricted and
will cause the combustion chamber to burn out. The exhaust pipe
should be checked and also be vacuumed, if required.
11.6 Checking Hoses and Tubes
Every so often, check water hoses and tubes for leaks or weak
points. Check air and fuel lines, pay close attention to the
condition of the hoses at the point where they connect to a
