If condensate is not draining from the system, check for improper routing of the drainage tubes or blockage in the drainage system. Tubing must be installed with a continuous fall in the direction of condensate flow. Sags may trap water, defeating the intended operation. Check for blockage by disconnecting drainage tubes at the collector and the vent diffuser. Probe these openings with a tool or wire hook to dislodge any debris.

Limestone gravel neutralizer is required in the condensate tray to prevent corrosion. This material should be replaced once a year to assure its continuous benefit. Replacement packages are available from Teledyne Laars or its representatives.

It is normal that a blue/green deposit forms in the neutralizer. This is caused by very small concentrations of copper ions present in the condensate. By increasing the pH of the condensate, the limestone causes this material to precipitate and be retained in the gravel.

4H. Major Component Service

The venturi assembly, the burner assembly and the heat exchanger tube assembly can be replaced if necessary, but correct procedures and use of only factory-provided parts are essential to assure satisfactory service and safe operation. Sealing the system with the specified sealers and gaskets is especially important. Contact the Teledyne Laars Service Department for information.

5A. General Information

NOTES:

1.The Hi-E2 is design certified by International Approval Services as a swimming pool heater under ANSI Standard Z21.56 for use in the United States and Standard CAN1-4.7-M85 for use in Canada.

2.The Hi-E2 pool heater is certified for use indoors or outdoors in the United States.

3.The Hi-E2 pool heater is for use with natural or liquefied petroleum gas. Ratings apply to either fuel.

4.De-rating for elevation is not necessary because of the Hi-E2 heater's special combustion system. Reduced barometric pressure at high elevations naturally decreases input and output by approximately three percent per 1000 feet above sea level.

5.Heaters require 115V, 60Hz electrical power.

6.Working pressure 75 psig.
