Start-Up Preparation

3.Fill the outer tank to correct system pressure. Correct pressure will vary with each application.

NOTICE

Typical residential system fill pressure is 12 psi. System pressure will increase when system temperature increases. Operating pressure of the system should never exceed 25 psi.

4.Allow air to escape from the outer tank by opening the automatic air vent provided with the ELITE.

5.Purge air in each zone of the primary sys- tem through the purge valve. Open air vents to allow air to be purged in the zones.

6.Once the system is completely filled and purged of all air, check the system pressure and check for leaks.

Check Low Water Cut-Off Device

-The ELITE is provided with a factory installed Low Water Cut-Off device that measures system pressure of more than 10 psi.

-Remove the front jacket panel and check for continuity across the low water cut-off device wire terminals. The contacts should be closed when sys- tem pressure is greater than 10 psi.

Check For Gas Leaks (if applicable)

WARNING

Prior to start-up and during initial oper- ation, smell near the floor and around the unit for gas odorant or any unusual odor. Do not proceed with the start-up if there is any indication of a gas leak. Any leaks found must be repaired immediately.

WARNING

Propane installations only - The propane supplier mixes an odorant with the propane to make its presence detectable. In some cases the odorant can fade and the gas may no longer have an odor.

Prior to start-up of the unit and period- ically after start-up have the propane supplier check and verify the odorant level.

Check Thermostat Circuit

-Unplug the Room Thermostat Snap-set located on the rear of the unit.

-Connect a voltmeter across the end ter- minals of the male half of the Room Thermostat Snap-set.

-Close each thermostat, zone valve and relay in the external circuit one zone at a time and check the voltage reading across the plug.

-There should NEVER be voltage mea- sured at the plug.

-If voltage is measured at the plug under any condition, check and correct the external wiring.

NOTICE

In systems using 3-wire zone valves backfeed of voltage to the unit is a com- mon problem. Use an isolation relay to prevent voltage from the external circuit entering the Room Thermostat Snap- set.
