Section 7, Plumbing the System
International Thermal Research 7-3
Do not operate the Hurricane® Zephyr Heating System until a proper
anti-freeze (heat transfer fluid) solution has been added to the
heating system and all trapped air has been bled. An inadequate
mixture may cause system circulation problems and potential heating
system damage and/or personal injury. Use only a non-toxic,
propylene glycol-based coolant with additives recognized as safe
“GRAS” by the FDA. Refer to the anti-freeze manufacturer
recommendations for instructions for your application.
6. Ensure that the coolant flow is adequate through the Hurricane
®
Zephyr Heating System. The flow rate through the space heating
loop should be at least 2.5 GPM. A large temperature difference
between each subsequent fan in the space heating loop (when the
Hurricane
®
Zephyr is running and up to normal operating
temperature) is an indication of inadequate flow. In a properly
flowing system, each fan in the space heating loop will have an outlet
temperature that is only a few degrees cooler than the preceding fan.
The temperature difference will be larger if the fan has a higher BTU
output.
7. The Hurricane
®
Zephyr should be filled and flushed prior to operation
to remove any foreign debris.
8. Slip-on foam insulation coverings may be used over the hose fittings
to reduce heat loss.
