Maintenance
11.1 The First Few Weeks
Once the Hurricane® Zephyr™ HW heater has been installed to
approved standards and workmanship, and you have test
operated it a few times, the system will require little
maintenance.
About two weeks after your Hurricane® Zephyr™ HW heater has
been running, you should conduct a general inspection of the
entire system.
Check for any leaks in the exhaust, fuel, or water systems.
Tighten all clamps.
It is strongly recommended that the Hurricane® Zephyr™
HW heater be started and allowed to run through one
complete heating cycle at least every 30 to 45 days to
ensure its proper function and to verify the proper
operation of all components.
11.2 Adding Heat Transfer Fluid
(Antifreeze)
Once the system has been filled with water and purged of all air
during the installation procedure, you need to operate the heater
at normal temperatures and check for
leaks. If you do not find any, add antifreeze to lubricate the
pump and prevent the water system from corroding or freezing
in cold weather. See Sec. 7, Plumbing and filling the System -7.6
pg. 7-7.
PRECAUTION: 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.
IT IS VERY IMPORTANT TO NEVER USE WATER ONLY AS A HEAT
TRANSFER FLUID.
