LP- 293 REV. 9.2.14
 Hardness less than 7 grains
o Consult local water treatment companies for unusually hard water areas (above 7 grains hardness).
 Chlorine concentration less than 100 ppm
o Using chlorinated fresh water should be acceptable as levels are typically less than 5 ppm.
o Do not connect the boiler to directly heat swimming pool or spa water.
o Do not fill boiler or operate with water containing chlorine in excess of 100 ppm.
 *NOTE: It is recommended to clean heat exchanger at least once a year to prevent lime scale buildup. To clean the heat
exchanger, follow the maintenance procedure in Part 13, Section B of this manual.
Hardness: 7 grains
Chloride levels: 100 ppm

G. FREEZE PROTECTION FLUIDS
NEVER use automotive or standard glycol antifreeze, or ethylene glycol made for hydronic systems, with this boiler. Use only inhibited
propylene glycol solutions, which are specifically formulated for hydronic systems. Ethylene glycol is toxic and can attack gaskets and
seals used in hydronic systems.
Consider boiler piping and installation when determining boiler location.
NOTE: Damages resulting from incorrect installation or from use of products not approved by HTP, Inc. ARE NOT covered by warranty.

B. HOW BOILER OPERATES
Elite
®
condensing technology intelligently delivers hydronic heating while maximizing efficiency. Outlined below are the features of the
system and how they operate:
Stainless Steel Heat Exchanger - The highly efficient stainless steel heat exchanger is designed to extract all available heat from the
supply line before it is exhausted.
Modulating Combustion System - The combustion system will modulate the output of the burner during operation to match the
system demand and achieve the control set point while in operation. The set point can change by internal or external signals which
enhance the overall performance of the system.
Control – The integrated control system monitors the system and regulates fan speed to control boiler output. This allows the boiler to
deliver only the amount of heat energy required and nothing more.
