Section 7, Plumbing the System
7-4
The Hurricane
®
Chinook Heating System
•
All plumbing lines must be routed and secured to prevent
damage, chafing and kinking.
•
Ensure that the coolant flow is adequate through the Hurricane
®
Chinook Heating System. The flow rate through the space
heating loop should be at least 2.5 GPM. An indication of
inadequate flow is a large temperature difference between each
subsequent fan in the space heating loop (when the Hurricane
®
Chinook Heating System is running and up to normal operating
temperature). In a system with adequate flow, 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.
•
The Hurricane
®
Chinook should be filled and flushed prior to
operation to remove any foreign debris.
•
Use heavy-duty 3/4” heater hose or 5/8” PEX tubing. Slip-on
foam insulation coverings may be used over the hose fittings to
reduce heat loss. Secure all hose connections with constant
tension spring clamps.
7.3 What NOT to Do
The Hurricane
®
Chinook Heating System’s coolant distribution
pumps are one of the most critical parts of the system.
Never
let
the pumps run dry or damage will occur to the impellers. This is not
covered under warranty.
Don’t
use low-quality heater hose.
Don’t
let the hose come into contact with solvents, which may
cause it to soften and swell. If there is any risk that solvents may
contact the hose, insert it into PVC plastic tubing for protection.
